Technical specifications

Summary of the technical specifications of solution. Depending on the model, some features might not be available, or some specifications might not apply.

Note

  • Up to eight SC750 V4 trays can be installed in an N1380 13U enclosure.

  • Each SC750 V4 tray contains two compute nodes, node A and node B. Node A is the bottom node and node B is the top node when viewing the tray from the front of the N1380 enclosure.

  • Access one set of monitor (VGA port) and keyboard/mouse (USB port) peripheral per N1380 enclosure at a time is recommended per radiated emission compliance.

Processor

  • Supports two processors per node.

  • Supported CPU is 6th Gen Intel® Xeon® Scalable processors (codenamed Granite Rapid-AP)

    • Support up to 128 cores, base speeds up to 3.9 GHz, and TDP ratings up to 500W.

    • Twelve channels per processor

    • UPI 2.0

      • Six UPI per processor

      • x24 UPI link width with speed of 16, 20, and 24 GT/s.

    • New Socket Technology (Socket BR with PCIe 5.0) LGA 7529.

Note
  1. Use the Setup Utility to determine the type and speed of the processors in the node.
  2. For a list of supported processors, see Lenovo ServerProven website.
Memory

See Memory module installation rules and order for detailed information about memory configuration and setup.

  • Slots:

    • 24 DIMM slots per node, 12 DIMMs per processor. SC750 V4 only supports fully populated DIMM configuration.

  • Memory type and capacity:

    • 6th Gen Intel® Xeon® Scalable processors (codenamed Granite Rapid-AP)

      • Capacity:

        • 24Gb based DDR5 RDIMM: 48GB and 96 GB at 6400 MT/s

        • 32Gb based DDR5 RDIMM: 32GB, 64GB, and 128GB at 6400 MT/s

        • MRDIMM: 32GB and 64 GB at 8800 MT/s

      • Minimum capacity per node: 768 GB per node with twenty-four 32 GB RDIMMs

      • Maximum capacity per node: up to 3 TB memory with twenty-four 128 GB RDIMMs

  • Protection:

    • ECC

    • SDDC (for x4-based memory DIMMs)

    • ADDDC (for x4-based memory DIMMs)

Important

  • The tray only supports fully populated processor and memory configuration (2 processors and 24 DIMMs per node).

  • Mixing DIMM speed is not supported.

  • ADDDC not supported for 9x4 ECC DIMM (Value)

Storage expansion
Supports E3.S 1T or E3.S 2T NVMe solid-state (SSD) drives.

  • Up to four E3.S 1T NVMe SSD at the front of the server (location shared with PCIe adapters)

  • Up to two E3.S 2T NVMe SSD at the front of the server (location shared with PCIe adapters)

  • Up to two E3.S 1T NVMe SSD on top of processor cold plate on the water loop.

Attention
As a general consideration, do not mix standard 512-byte and advanced 4-KB format drives in the same RAID array because it might lead to potential performance issues.
Expansion slots

Up to two PCIe 5.0 x16 PCIe slots (slot 1 and slot 2) on the front per node for half-height half-length (HHHL) PCIe adapter (location shared with front E3.S NVMe SSDs)

Integrated functions and I/O connectors
Integrated functions

  • System I/O board (DCSCM)

  • Lenovo XClarity Controller (XCC), which provides service processor control and monitoring functions, video controller, and remote keyboard, video, mouse, and remote drive capabilities.
  • I/O connectors

    • One Gigabit Ethernet port with RJ45 connector (Dedicated XCC management connector)

    • Enclosure rear connectors: two Ethernet ports on the System Management Module 3 (SMM3) installed in the rear of the enclosure.

      Note

      It is recommended to use SMM3 Ethernet port as the default dedicated management network. If required to use node front Ethernet port as dedicated management network, refer to XCC user guide for network configuration instructions.

    • One Gigabit Ethernet port with RJ45 connector, shared between operating system and Lenovo XClarity Controller.

    • Two 25Gb SFP 28 ports. One port is shared between operating system and Lenovo XClarity Controller.

      Note

      Lenovo XClarity Controller connection is mutually exclusive between RJ45 Ethernet connector and 25Gb SFP28 Port 1.

    • Two USB 3.1 Gen 1 (5 Gbps) connectors

    • VGA connector

    • Maintenance port system log connector (Mini USB connector)

    • DisplayPort Alternate Mode Type-C connector

    • External diagnostics handset connector

  • Video controller (integrated into Lenovo XClarity Controller)
    • ASPEED
    • SVGA compatible video controller
    • Avocent Digital Video Compression
    • Video memory is not expandable
    Note
    Maximum video resolution is 1920 x 1200 at 60 Hz.
Network and I/O connectors

  • One Gigabit Ethernet port with RJ45 connector (Dedicated XCC management connector)

  • One Gigabit Ethernet port with RJ45 connector, shared between operating system and Lenovo XClarity Controller.

  • Two 25Gb SFP 28 ports. One port is shared between operating system and Lenovo XClarity Controller.

    Note

    Lenovo XClarity Controller connection is mutually exclusive between RJ45 Ethernet connector and 25Gb SFP28 Port 1.

Storage controllers
Onboard NVMe ports with software RAID support (Intel VROC NVMe RAID)

  • Intel VROC standard: requires an activation key and supports RAID levels 0, 1, and 10

  • Intel VROC Premium: requires an activation key and supports RAID levels 0, 1, 5, and 10

  • Intel VROC Boot: requires an activation key and supports RAID level 1 only

Electrical input
SC750 V4 tray installed in N1380 enclosure
Supports up to four 15000W Power Conversion Stations (PCS):

  • The enclosure must be installed with at least three PCS.

  • Input voltage: 380 – 480 Vac (Acbel DWC PCS)

  • Redundancy: work as N+1 with OVS and N+N with OVS (OVS: oversubscription)

  • Resetting SMM3 to factory defaults will cause the PCS redundancy mode to return to the default N+1 mode. If needed, re-configure PCS redundancy mode as the original or as loading required via SMM3.

CAUTION

Power Conversion Stations and redundant Power Conversion Stations in the enclosure must be with the same brand, power rating, wattage or efficiency level.

Mixing PCS manufactured by different vendors is not supported.

Note
Refer to SMM3 User Guide for more details of solution power status.
