Lenovo ThinkSystem SC750 V4 Neptune Server

The ThinkSystem SC750 V4 Neptune node is the next-generation high-performance server based on the sixth generation Lenovo Neptune® direct water cooling platform.

With two Intel Xeon 6900-series processors, the ThinkSystem SC750 V4 server combines the latest high-performance Intel processors and Lenovo's market-leading water-cooling solution, which results in extreme performance in dense packaging.

The direct water cooled solution is designed to operate by using warm water, up to 45°C (113°F). Chillers are not needed for most customers, meaning even greater savings and a lower total cost of ownership. Two nodes are installed in a tray and 8 trays are housed in the ThinkSystem N1380 enclosure, a 13U rack mount unit that fits in a standard 19-inch rack.

Lenovo Neptune and the ThinkSystem SC750 V4 are designed to operate at water inlet temperatures as low as the dew point allows, up to 45°C. This design eliminates the need for additional chilling and allows for efficient reuse of the generated heat energy in building heating or adsorption cold water generation. It uses treated de-ionized water as a coolant, a much safer and more efficient alternative to the commonly used PG25 Glycol liquid, reflecting our commitment to environmental responsibility.

The ThinkSystem SC750 V4 server tray uses a new design, where the trays are mounted vertically in the N1380 enclosure. This new design allows for two servers to be mounted on the tray using the larger Intel Xeon 6900-Series processors, along with memory DIMMs for all 12 memory channels of the processors.

Revolutionary Lenovo Neptune Design

Engineered for large-scale cloud infrastructures and High Performance Computing (HPC), Lenovo ThinkSystem SC750 V4 Neptune excels in intensive simulations and complex modeling. It is designed to handle technical computing, grid deployments, and analytics workloads in various fields such as research, life sciences, energy, engineering, and financial simulation.

At its core, Lenovo Neptune applies 100% direct warm-water cooling, maximizing performance and energy efficiency without sacrificing accessibility or serviceability. The SC750 V4 integrates seamlessly into a standard 19" rack cabinet with the ThinkSystem N1380 Neptune enclosure, featuring a patented blind-mate stainless steel dripless quick connection.

This design ensures easy serviceability and extreme performance density, making the SC750 V4 the go-to choice for compute clusters of all sizes - from departmental/workgroup levels to the world’s most powerful supercomputers – from Exascale to Everyscale®.

Lenovo Neptune utilizes superior materials, including custom copper water loops and patented CPU cold plates, for full system water-cooling. Unlike systems that use low-quality FEP plastic, Neptune features durable stainless steel and reliable EPDM hoses. The  N1380 enclosure features an integrated manifold that offers a patented blind-mate mechanism with aerospace-grade drip-less connectors to the compute trays, ensuring safe and seamless operation.

Compared to an equivalent air-cooled system, the SC750 V4 provides:

• Up to 10% performance increase through continuous turbo mode
• Up to 40% data center energy use reduction from server and infrastructure
• Up to 100% heat removal by water directly on the heat sources
• Up to 100% noise reduction by server fans in the data center

Lenovo’s direct water-cooled solutions are factory-integrated and are re-tested at the rack-level to ensure that a rack can be directly deployed at the customer site. This careful and consistent quality testing has been developed as a result of over a decade of experience designing and deploying DWC solutions to the very highest standards.

Scalability and performance

The ThinkSystem SC750 V4 server tray and ThinkSystem N1380 enclosure offer the following features to boost performance, improve scalability, and reduce costs:

• Each SC750 V4 node supports two high-performance Intel Xeon 6900-series processors, 24x TruDDR5 RDIMMs or MRDIMMs, up to two PCIe 5.0 slots for high-speed I/O, and up to two drive bays.
• 16x SC750 V4 nodes are mounted in 8x trays which are installed vertically in the 13U ThinkSystem N1380 enclosure. With server nodes effectively occupying less than 1U of rack space, it is a dense, scalable, and high performance offering.
• Each node supports one or two Intel Xeon 6900-series processors. Each processor has:
  • Up to 128 cores and 256 threads
  • Core speeds of up to 2.7 GHz
  • TDP ratings of up to 500 W
• Support for DDR5 memory DIMMs to maximize the performance of the memory subsystem. Each node supports the following:
  • Up to 24 DDR5 memory DIMMs, 12 DIMMs per processor
  • 12 memory channels per processor (1 DIMM per channel)
  • Support for RDIMMs (operating at 6400 MHz) and MRDIMMs (operating at 8800 MHz)
  • Using 24x 128GB RDIMMs, the server supports up to 3TB of system memory
• Each node has two front bays that support either slots or E3.S drives, giving the following choices:
  • 2x PCIe 5.0 x16 slots
  • 1x PCIe slot plus 2x E3.S 1T drives (or 1x E3.S 2T drive)
  • 4x E3.S 1T drives (or 2x E3.S 2T drives)
• In addition, each node supports 2x E3.S 1T drives mounted on cold plates on top of the two processors
• The server is Compute Express Link (CXL) v2.0 Ready. With CXL 2.0 for next-generation workloads, you can reduce compute latency in the data center and lower TCO. CXL is a protocol that runs across the standard PCIe physical layer and can support both standard PCIe devices as well as CXL devices on the same link.
• All supported drives are E3.S NVMe drives, to maximize I/O performance in terms of throughput, bandwidth, and latency.
• The node includes one Gigabit and two 25 Gb Ethernet onboard ports for cost effective networking. High speed networking can be added through the included PCIe slots. The Gigabit port and one of the 25Gb ports support NC-SI for BMC management communication to the BMC in addition to the host communication.
• The node offers PCI Express 5.0 I/O expansion capabilities that doubles the theoretical maximum bandwidth of PCIe 4.0 (32GT/s in each direction for PCIe 5.0, compared to 16 GT/s with PCIe 4.0). A PCIe 5.0 x16 slot provides 128 GB/s bandwidth, enough to support a 400GbE network connection.

Energy efficiency

The direct water cooled solution offers the following energy efficiency features to save energy, reduce operational costs, increase energy availability, and contribute to a green environment:

• Water cooling eliminates power that is drawn by cooling fans in the enclosure and dramatically reduces the required air movement in the server room, which also saves power. In combination with an Energy Aware Runtime environment, savings as much as 40% are possible in the data center due to the reduced need for air conditioning.
• Water chillers may not be required with a direct water cooled solution. Chillers are a major expense for most geographies and can be reduced or even eliminated because the water temperature can now be 45°C instead of 18°C in an air-cooled environment.
• With the new water-cooled power conversion stations and SMM3, essentially 100% system heat recovery is possible, depending on water and ambient temperature chosen. At 45°C water temperature and 30°C room temperature it will be typically around 95% through surface radiated heat. Heat energy absorbed may be reused for heating buildings in the winter, or generating cold through Adsorption Chillers, for further operating expense savings.
• The processors and other microelectronics are run at lower temperatures because they are water cooled, which uses less power, and allows for higher performance through Turbo Mode.
• The processors are run at uniform temperatures because they are cooled in parallel loops, which avoid thermal jitter and provides higher and more reliable performance at same power.
• Low-voltage 1.1V DDR5 memory offers energy savings compared to 1.2V DDR4 DIMMs, an approximately 20% decrease in power consumption
• 80 PLUS Titanium-compliant power conversion stations ensure energy efficiency.
• Power monitoring and management capabilities through the System Management Module in the N1380 enclosure.
• The System Management Module (SMM3) automatically calculates the power boundaries at the enclosure level; the protective capping feature ensures overall power consumption stay within limits, adjusting dynamically based on the server and power conversion station status change.
• Lenovo power/energy meter based on TI INA228 measures DC power for the CPU at higher than 97% accuracy and 100 Hz sampling frequency to the XCC and can be leveraged both in-band and out-of-band using IPMI raw commands.
• Optional Lenovo XClarity Energy Manager provides advanced data center power notification, analysis, and policy-based management to help achieve lower heat output and reduced cooling needs.
• Optional Energy Aware Runtime provides sophisticated power monitoring and energy optimization on a job-level during the application runtime without impacting performance negatively.

Manageability and security

The following powerful systems management features simplify local and remote management of the SC750 V4 server:

• The server includes an XClarity Controller 3 (XCC3) to monitor server availability.

• LiCO web portal provides workflows for both AI and HPC, and supports multiple AI frameworks, allowing you to leverage a single cluster for diverse workload requirements.
• Integrated Trusted Platform Module (TPM) 2.0 support enables advanced cryptographic functionality, such as digital signatures and remote attestation.
• Supports Secure Boot to ensure only a digitally signed operating system can be used.
• Industry-standard Advanced Encryption Standard (AES) NI support for faster, stronger encryption.
• With the System Management Module (SMM) installed in the enclosure, only one Ethernet connection is needed to provide remote systems management functions for all SC750 V4 servers and the enclosure.
• The SMM3 management module has two Ethernet ports which allows a single Ethernet connection to be daisy chained, up to 99 connections (eg 3 enclosures and 96 servers), thereby significantly reducing the number of Ethernet switch ports needed to manage an entire rack of SC750 V4 servers and N1380 enclosures.
• The N1380 enclosure and its power conversion stations include drip sensors that monitor the inlet and outlet manifold quick connect couplers; leaks are reported via the SMM.

The following table lists the standard specifications of the SC750 V4 server tray.

The ThinkSystem N1380 enclosure provides shared high-power and high-efficiency power conversion stations. The SC750 V4 servers connect to the midplane of the N1380 enclosure. This midplane connection is for power (via a 48V busbar) and control only; the midplane does not provide any I/O connectivity.

The following table lists the standard specifications of the enclosure.

The SC750 V4 node and N1380 enclosure are configured by using the configure-to-order (CTO) process with the Lenovo Cluster Solutions configurator (x-config).

The following table lists the base CTO models and base feature codes

The SC750 V4 node supports two processors as follows:

• Two Intel Xeon 6900-series processors (formerly codenamed "Granite Rapids AP")

Topics in this section:

• Processor options
• Processor features
• UEFI operating modes

Processor options

All supported Intel Xeon 6900P-series processors have the following characteristics:

• 12 DDR5 memory channels at 1 DIMM per channel
• 6 UPI links between processors at 24 GT/s
• 96 PCIe 5.0 I/O lanes

The following table lists the Intel Xeon 6900P-series processors that are supported by the SC750 V4.

The following table summarizes the key features of the Intel Xeon 6900-series processors with P-cores that are supported in the SC750 V4.

The following table lists the feature codes that allow you to specify the mode you wish to preset in the factory for CTO orders.

The preset modes for the SC750 V4 are as follows:

• General Computing - Power Efficiency (feature C3JB): This workload profile optimizes the performance per watt efficiency with a bias towards performance. This workload profile is analogous to “Efficiency – Favor Performance” operating mode on ThinkSystem V3 servers. This profile contains settings for ENERGY STAR® and ERP Lot9 compliance.
• General Computing - Peak Frequency (feature C3JA): This workload profile is defined by the requirement to drive the highest core frequencies out of a processor across a subset of cores available – not for all cores active. This workload profile benefits workloads requiring either high per core and / or overall CPU package frequency. These workloads may have variable resource demands, are relatively insensitive to overall platform latency, and are generally CPU clock constrained. Tuning a system for highest possible core frequency may mean allowing inactive cores to transfer in and out of sleep states (C-states), which allows active cores to run at higher frequency for different durations of time. Allowing cores to go into low power states allows for higher per core frequency but can introduce “jitter” in the systems clock frequency.
• General Computing - Max Performance (feature C3J9): This workload profile maximizes the absolute performance of the system without regard for power savings. Power savings features are disabled. This operating mode should be used when an application can sustain work across all cores simultaneously and is Non-uniform Memory Access (NUMA) aware.
• High Performance Computing (HPC) (feature C3J8): This profile is for customers running large-scale scientific and engineering workloads. These environments tend to be clustered environments where each node performs at maximum utilization for extended periods of time, and the application is Non-uniform Memory Access (NUMA) aware.

The SC750 V4 uses Lenovo TruDDR5 RDIMM memory operating at 6400 MHz and MRDIMM memory operating at 8800 MHz. The server supports up to 24 DIMMs with 2 processors. The processors have 12 memory channels and support 1 DIMM per channel (DPC). The server supports up to 3TB of memory using 24x 128GB RDIMMs and two processors.

Lenovo TruDDR5 memory uses the highest quality components that are sourced from Tier 1 DRAM suppliers and only memory that meets the strict requirements of Lenovo is selected. It is compatibility tested and tuned to maximize performance and reliability. From a service and support standpoint, Lenovo TruDDR5 memory automatically assumes the system warranty, and Lenovo provides service and support worldwide.

The following table lists the memory options that are currently supported by the SC750 V4.

The following rules apply when selecting the memory configuration:

• The SC750 V4 only supports quantities of 12 DIMMs per processor (24 DIMMs total), so that all memory channels are populated
• Mixing of DIMMs is not supported; all DIMMs must the same part numbers

See the following Lenovo Press papers for more information:

• Introduction to MRDIMM Memory, https://lenovopress.com/lp2028
• Introduction to DDR5 Memory, https://lenovopress.com/lp1618
• RAS Features of the Lenovo ThinkSystem Intel Servers, https://lenovopress.lenovo.com/lp1711

If memory channel mirroring is used, then DIMMs must be installed in pairs (minimum of one pair per processor), and both DIMMs in the pair must be identical in type and size. 50% of the installed capacity is available to the operating system. Memory rank sparing is not supported.

GPUs are not offered in the SC750 V4.

For GPU support in a water-cooled solution, the ThinkSystem SC777 V4, SR780a V3, SD650-N V3 and SD665-N V3 all enable high-performance water-cooled NVIDIA GPUs.

For details, see the related product guide:

• ThinkSystem SC777 V4 datasheet
• ThinkSystem SR780a V3 product guide
• ThinkSystem SD650-N V3 product guide
• ThinkSystem SD665-N V3 product guide

The SC750 V4 node supports up to 6x E3.S SSDs. These are internal drives - they are not front accessible and are non-hot-swap.

The locations of the drives are as shown below:

• 2x E3.S 1T drives or 1x E3.S 2T drive mounted in a bay in front slot 1
• 2x E3.S 1T drives or 1x E3.S 2T drive mounted in a bay in front slot 2
• 1x E3.S 1T drive mounted on top of CPU 1
• 1x E3.S 1T drive mounted on top of CPU 2

The drive bays in slot 1 and slot 2 may instead be configured as PCIe slots as described in the I/O expansion options section.

The following figure shows the location of the drives.

Figure 7. SC750 V4 internal drive bays

Configuration notes:

• The node supports only supports NVMe drives
• The drives are connected to onboard controllers; RAID functionality is provided using Intel VROC. Details are in the Intel VROC onboard RAID section.
• NVMe drives are connected to CPUs as follows:
  • Drives in front bay 1 connect to CPU 1
  • Drives in front bay 2 connect to CPU 2
  • Drives mounted on the CPUs are both connected to CPU 2

The feature codes to select the appropriate storage cage are listed in the following table.

The drives of the SC750 V4 are connected to integrated NVMe storage controllers.

RAID functionality is provided by Intel VROC, for both SATA drives and NVMe drives.

The following tables list the drive options for internal storage of the server.

The server supports the external USB optical drive listed in the following table.

The drive is based on the Lenovo Slim DVD Burner DB65 drive and supports the following formats: DVD-RAM, DVD-RW, DVD+RW, DVD+R, DVD-R, DVD-ROM, DVD-R DL, CD-RW, CD-R, CD-ROM.

Each SC750 V4 node supports 1x or 2x slots depending on the configuration:

• Slot 1: PCIe 5.0 x16 slot connected to CPU 1
• Slot 2: PCIe 5.0 x16 slot connected to CPU 2

The location of the slots is shown in the following figure.

Figure 8. SC750 V4 PCIe slots

Both slots are implemented using a 1-slot riser. Ordering information is in the following table.

One or both of these slots can alternatively be configured as internal E3.S NVMe drive bays, as described in the Internal storage section.

The following figure shows the four different networking slot configurations, including Shared I/O and Socket Direct.

Figure 9. SC750 V4 slot configurations

Onboard ports

The SC750 V4 has three onboard network ports:

• 2x 25GbE ports, connected to an onboard Broadcom 57414 controller, implemented with SFP28 cages for optical or copper connections. Supports 1Gb, 10Gb and 25Gb connections.
• 1x 1GbE port, connected to an onboard Intel I210 controller, implemented with an RJ45 port for copper cabling

Locations of these ports is shown in the Components and connectors section. The 1GbE port and 25GbE Port 1 both support NC-SI for remote management. For factory orders, to specify which ports should have NC-SI enabled, use the feature codes listed in the Remote Management section. If neither is chosen, both ports will have NC-SI disabled by default.

For the specifications of the 25GbE ports including the supported transceivers and cables, see the Broadcom 57414 product guide:
https://lenovopress.lenovo.com/lp0781-broadcom-57414-25gb-ethernet-adapters

Shared I/O

The SC750 V4 supports a feature called Shared I/O (SharedIO), also known as NVIDIA Networking Multi-Host technology, where a single network connection is shared between the two nodes in a tray. With Shared I/O, the NVIDIA adapter (feature BKSL or BKSP) is installed in one node in a tray, and a cable (feature BZ7E) is used to connect the adapter to a PCIe connector on the adjacent node in the same tray. The result is that the two nodes share the network connection of the adapter with significant savings both in the cost of the adapters but also the cost of switch ports.

Configuration rules:

• Shared I/O requires the use of cable ThinkSystem SC750 V4 ConnectX-7 Auxiliary Cable, option 4X97B01936, feature BZ7E
• The adapter must be installed in Slot 1 of node B. The cable connects the adapter to the onboard connector for Slot 1 of node A

Socket Direct

The SC750 V4 also supports a feature called Socket Direct where an adapter installed in a node is connected to both processors in that node at the same time. Socket Direct enables direct PCIe access to both processors, eliminating the need for network traffic having to traverse the inter-process bus. This optimizes overall system performance and maximum throughput for the most demanding applications and markets.

In the SC750 V4, Socket Direct is achieved by installing the NVIDIA adapter in slot 2 (connects to CPU 2) and a cable (feature BZ7E) is used to connect the adapter to the PCIe connector for slot 1 (which connects to CPU 1).

Configuration rules:

• Socket Direct requires the use of cable ThinkSystem SC750 V4 ConnectX-7 Auxiliary Cable, option 4X97B01936, feature BZ7E
• The adapter must be installed in Slot 2 of each node. The cable connects the adapter to the onboard connector for Slot 1
• Slot 1 must remain empty if Socket Direct is configured; no drive or adapter can be installed
• By default, the ConnecX-7 adapter connects at PCIe Gen5 and the Auxiliary Cable connects at PCIe Gen4. This can be changed in UEFI.

For more information, including the transceivers and cables that each adapter supports, see the list of Lenovo Press Product Guides in the Networking adapters category:
https://lenovopress.com/servers/options/ethernet

The SC750 V4 does not support storage host bus adapters.

One of the most notable features of the ThinkSystem SC750 V4 offering is direct water cooling. Direct water cooling (DWC) is achieved by circulating the cooling water directly through cold plates that contact the CPU thermal case, DIMMs, drives, adapters, and other high-heat-producing components in the node.

One of the main advantages of direct water cooling is the water can be relatively warm and still be effective because water conducts heat much more effectively than air. Depending on the environmentals like water and air temperature, effectively 100% of the heat can be removed by water cooling; in configurations that stay slightly below that, the rest can be easily managed by a standard computer room air conditioner. Measured data at a customer data center shows 98% heat capture at 45°C water inlet temperature and 99% heat capture at 40°C water inlet temperature and 26.6°C ambient temperature with insulated racks using the SD650-N V2.

Allowable inlet temperatures for the water can be as high as 45°C (113°F) with the SC750 V4. In most climates, water-side economizers can supply water at temperatures below 45°C for most of the year. This ability allows the data center chilled water system to be bypassed thus saving energy because the chiller is the most significant energy consumer in the data center. Typical economizer systems, such as dry-coolers, use only a fraction of the energy that is required by chillers, which produce 6-10°C (43-50°F) water. The facility energy savings are the largest component of the total energy savings that are realized when the SC750 V4 is deployed.

The advantages of the use of water cooling over air cooling result from water’s higher specific heat capacity, density, and thermal conductivity. These features allow water to transmit heat over greater distances with much less volumetric flow and reduced temperature difference as compared to air.

For cooling IT equipment, this heat transfer capability is its primary advantage. Water has a tremendously increased ability to transport heat away from its source to a secondary cooling surface, which allows for large, more optimally designed radiators or heat exchangers rather than small, inefficient fins that are mounted on or near a heat source, such as a CPU.

The SC750 V4 offering uses the benefits of water by distributing it directly to the highest heat generating node subsystem components. By doing so, the offering realizes 7% - 10% direct energy savings when compared to an air-cooled equivalent. That energy savings results from the removal of the system fans and the lower operating temp of the direct water-cooled system components.

The direct energy savings at the enclosure level, combined with the potential for significant facility energy savings, makes the SC750 V4 an excellent choice for customers that are burdened by high energy costs or with a sustainability mandate.

Water is delivered to the enclosure from a coolant distribution unit (CDU) via water hoses, inlet and return. As shown in the following figure, each enclosure connects to the CDU via rack supply hoses. Typically each enclosure connects to the rack supply directly, however two adjacent enclosures can connected in series (daisy chain) to use the same supply, provided the inlet water of the first enclosure is 30°C.

The midplane in the enclosure routes the water via QuickConnects to each of the eight nodes, and each of the four power conversion stations.

Figure 10. N1380 enclosure water connections

The water flows through the SC750 V4 tray to cool all major heat-producing components. The inlet water is split into two parallel paths, one for each node in the tray. Each path is then split further to cool the processors, memory, drives, and adapters.

During the manufacturing and test cycle, Lenovo’s water-cooled nodes are pressure tested with Helium according to ASTM E499 / E499M – 11 (Standard Practice for Leaks Using the Mass Spectrometer Leak Detector in the Detector Probe Mode) and later again with Nitrogen to detect micro-leaks which may be undetectable by pressure testing with water and/or a water/glycol mixture as Helium and Nitrogen have smaller molecule sizes.

This approach also allows Lenovo to ship the systems pressurized without needing to send hazardous antifreeze-components to our customers.

Onsite the materials used within the water loop from the CDU to the nodes should be limited to copper alloys with brazed joints, Stainless steels with TIG and MIG welded joints and EPDM rubber. In some instances, PVC might be an acceptable choice within the facility.

The water the system is filled with must be reasonably clean, bacteria-free water (< 100 CFU/ml) such as de-mineralized water, reverse osmosis water, de-ionized water, or distilled water. It must be filtered with in-line 50 micron filter. Biocide and Corrosion inhibitors ensure a clean operation without microbiological growth or corrosion. For details about the implementation of Lenovo Neptune water cooling, see the document Lenovo Neptune Direct Water-Cooling Standards.

Lenovo Data Center Power and Cooling Services can support you in the design, implementation and maintenance of the facility water-cooling infrastructure.

Water connections to the N1380 enclosure are provided using hoses that connect directly to the coolant distribution unit (CDU), either an in-rack CDU or in-row CDU. As shown in the following figure, hose lengths required depend on the placement of the N1380 in the rack cabinet.

Figure 11. Hose lengths based on the position of the N1380 enclosure in the rack cabinet

Water connections are made up of the following:

• Short hoses permanently attached to the rear of the N1380 enclosure
• Intermediate hoses, orderable as three different pairs of hoses, based on the location of the N1380 enclosure in the rack. Ordering information for these hoses is listed in the table below.
• Connection to the CDU through additional hoses or valves on the data center water loop. Lenovo Datacenter Services can provide the end-to-end enablement for your water infrastructure needs.

The Intermediate hoses have a Sanitary Flange with a 1.5-inch Tri-Clamp at the CDU/data center end, as shown in the figure below.

Figure 12. Connections of the Intermediate hoses

Ordering information for the Intermediate hoses to supply and return the water are listed in the following table. Hoses can either be stainless steel or EPDM, depending on the data center requirements.

The N1380 enclosure supports up to four water-cooled Power Conversion Stations. The use of water-cooled power conversion stations enables an even greater amount of heat can be removed from the data center using water instead of air-conditioning.

The Power Conversion Stations supply internal system power to a 48V busbar. This innovative design merges power conversion, rectification, and distribution into a single unit, a departure from traditional setups that require separate units, including separate power supplies, resulting in best-in-class efficiency.

Figure 13. N1380 power conversion stations

The N1380 supports the power conversion stations listed in the following table.

Quantities of 2, 3 or 4 are supported. The power conversion stations provide N+1 redundancy with oversubscription, depending on population and configuration of the node trays. Power policies with N+N redundancy with 4x power conversion stations are supported. Power policies with no redundancy are also supported.

The power conversion stations have the following features:

• 80 PLUS Titanium certified
• Input: 180~528Vac (nominal 200~480Vac), 3-phase, WYE or Delta
• Input current:
  • Delta: 46.53A (34A per phase)
  • WYE: 23.79A (34A per phase)
• Supports N+N, N+1 power redundancy or non-redundant power configurations:
• Power management configured through the SMM
• Built-in overload and surge protection

Power policies and power output

The following table lists the enclosure power capacity based on the power policy and the number of power modules installed.

Notes in the table:

1. N+1+OVS (oversubscription) is the default if >1 PSU is installed. N+0 is the default with 1 PSU installed.
2. If N+N is selected and there is an AC domain fault (2 PSUs go down), the power capacity is reduced to the value shown in parentheses within 1 second. Example: If 2+2 policy is selected & all 4 PSUs are operational, the power capacity is 36KWDC. If an AC domain faults, 2 PSU go down, and the power is reduced to 30KW within 1 second
3. If N+1 is selected and there is a PSU fault, the power capacity is reduced to <= the value shown in parentheses within 1 second. Example: If 3+1 policy is selected & all 4 PSUs are operational, the power capacity is 54KWDC. If a PSU faults, the power is reduced to <=45KW within 1 second. GPU trays are hard throttled w PWRBRK#. Intel trays are proprotionally throttled with Psys power capping
4. If the chassis is in the degraded redundancy state, due to 1 or more PSU faults, and an additional PSU fails, the chassis will attempt to stay alive by hard-throttling the trays (via PROCHOT# & PWRBRK#), but there is no guarantee. There is risk that the chassis could power off if the PSU rating is exceeded
5. For the redundant power policies, only OVS modes are selectable in SMM (ie. OVS is always enabled). When a user creates a hardware config in DCSC, a chassis max power estimate is completed, via an LCP API call. If the chassis DC max power is in between the chassis degraded power capacity shown in parentheses and the chassis normal power capacity, a warning is displayed stating that the server could be throttled if a PSU fails. If the customer doesn’t want potential throttling, they either need to reduce their config or select a different combo of PSUs/policy to achieve a higher power budget
6. Possible future feature

Power cables

The power conversion stations function at a 32A current, but the power cables enable two PCS units to share a single 63A connection from the data center. Consequently, for racks fully equipped with 12 power conversion stations, only six power connections from the data center are needed.

The N1380 enclosure supports the following power cables.

The SMM has the following ports and LEDs:

• 2x Gigabit Ethernet RJ45 ports for remote management access
• USB port and activation button for service
• SMM reset button
• System error LED (yellow)
• Identification (ID) LED (blue)
• Status LED (green)
• System power LED (green)

The USB service button and USB service port are used to gather service data in the event of an error. Pressing the service button copies First Failure Data Collection (FFDC) data to a USB key installed in the USB service port. The reset button is used to perform an SMM reset (short press) or to restore the SMM back to factory defaults (press for 4+ seconds).

The use of two RJ45 Ethernet ports enables the ability to daisy-chain the Ethernet management connections thereby reducing the number of ports you need in your management switches and reducing the overall cable density needed for systems management. With this feature you can connect the first SMM to your management network and the SMM in a second enclosure connects to the first SMM. The SMM in the third enclosure can then connect to the SMM in the second enclosure.

Up to 3 enclosures can be connected in a daisy-chain configuration and all 48 servers in those enclosures can be managed remotely via one single Ethernet connection.

Notes:

• If you are using IEEE 802.1D spanning tree protocol (STP) then at most 3 enclosures can be connected together
• Do not form a loop with the network cabling. The dual-port SMM at the end of the chain should not be connected back to the switch that is connected to the top of the SMM chain.

For more information about the SMM, see the SMM3 User's Guide:

Platform Firmware Resiliency - Lenovo ThinkShield

Lenovo's ThinkShield Security is a transparent and comprehensive approach to security that extends to all dimensions of our data center products: from development, to supply chain, and through the entire product lifecycle.

The ThinkSystem SC750 V4 includes Platform Firmware Resiliency (PFR) hardware Root of Trust (RoT) which enables the system to be NIST SP800-193 compliant. This offering further enhances key platform subsystem protections against unauthorized firmware updates and corruption, to restore firmware to an integral state, and to closely monitor firmware for possible compromise from cyber-attacks.

PFR operates upon the following server components:

• UEFI image – the low-level server firmware that connects the operating system to the server hardware
• XCC image – the management “engine” software that controls and reports on the server status separate from the server operating system
• FPGA image – the code that runs the server’s lowest level hardware controller on the motherboard

The Lenovo Platform Root of Trust Hardware performs the following three main functions:

• Detection – Measures the firmware and updates for authenticity
• Recovery – Recovers a corrupted image to a known-safe image
• Protection – Monitors the system to ensure the known-good firmware is not maliciously written

These enhanced protection capabilities are implemented using a dedicated, discrete security processor whose implementation has been rigorously validated by leading third-party security firms. Security evaluation results and design details are available for customer review – providing unprecedented transparency and assurance.

The SC750 V4 includes support for Secure Boot, a UEFI firmware security feature developed by the UEFI Consortium that ensures only immutable and signed software are loaded during the boot time. The use of Secure Boot helps prevent malicious code from being loaded and helps prevent attacks, such as the installation of rootkits. Lenovo offers the capability to enable secure boot in the factory, to ensure end-to-end protection. Alternatively, Secure Boot can be left disabled in the factory, allowing the customer to enable it themselves at a later point, if desired.

The following table lists the relevant feature code(s).

  Professional Services consultants perform infrastructure design and implementation planning to support your strategy. The high-level architectures provided by the assessment service are turned into low level designs and wiring diagrams, which are reviewed and approved prior to implementation. The implementation plan will demonstrate an outcome-based proposal to provide business capabilities through infrastructure with a risk-mitigated project plan.

• Basic Hardware Installation

  Lenovo experts can seamlessly manage the physical installation of your server, storage, or networking hardware. Working at a time convenient for you (business hours or off shift), the technician will unpack and inspect the systems on your site, install options, mount in a rack cabinet, connect to power and network, check and update firmware to the latest levels, verify operation, and dispose of the packaging, allowing your team to focus on other priorities.

• Deployment Services

  When investing in new IT infrastructures, you need to ensure your business will see quick time to value with little to no disruption. Lenovo deployments are designed by development and engineering teams who know our Products & Solutions better than anyone else, and our technicians own the process from delivery to completion. Lenovo will conduct remote preparation and planning, configure & integrate systems, validate systems, verify and update appliance firmware, train on administrative tasks, and provide post-deployment documentation. Customer’s IT teams leverage our skills to enable IT staff to transform with higher level roles and tasks.

• Integration, Migration, and Expansion Services

  Move existing physical & virtual workloads easily, or determine technical requirements to support increased workloads while maximizing performance. Includes tuning, validation, and documenting ongoing run processes. Leverage migration assessment planning documents to perform necessary migrations.

• Data Center Power and Cooling Services

  The Data Center Infrastructure team will provide solution design and implementation services to support the power and cooling needs of the multi-node chassis and multi-rack solutions. This includes designing for various levels of power redundancy and integration into the customer power infrastructure. The Infrastructure team will work with site engineers to design an effective cooling strategy based on facility constraints or customer goals and optimize a cooling solution to ensure high efficiency and availability. The Infrastructure team will provide the detailed solution design and complete integration of the cooling solution into the customer data center. In addition, the Infrastructure team will provide rack and chassis level commissioning and stand-up of the water-cooled solution which includes setting and tuning of the flow rates based on water temperature and heat recovery targets. Lastly, the Infrastructure team will provide cooling solution optimization and performance validation to ensure the highest overall operational efficiency of the solution.
