Technical specifications

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

Processor
  • The server supports one of the following Intel® processors:
    • Xeon® E
    • Pentium®
    Note
    Only the Xeon® E processor supports Intel® Trusted Execution Technology (Intel® TXT) feature.

  • Designed for LGA 1700 socket

  • Scalable up to 8 cores per socket

  • Supports TDP up to 95W

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.

  • Minimum: 16 GB
  • Maximum: 128 GB
  • Slots: four DIMM slots (two channels, two DIMMs per channel)
  • Memory module type:
    • TruDDR5 4800MHz (1Rx8) ECC UDIMM: 16 GB (1Rx8)
    • TruDDR5 4800MHz (2Rx8) ECC UDIMM: 32 GB (2Rx8)
Note
Memory operates at up to 4400 MHz, depending on the processor selected and DIMM population order.

For a list of supported memory modules, see Lenovo ServerProven website.

M.2 Drive
The server supports up to two SATA M.2 drives of the following drive form factors:
  • 42 mm (2242)
  • 60 mm (2260)
  • 80 mm (2280)
  • 110 mm (22110)
Supports the following M.2 drive capacity:
  • 240 GB
  • 480 GB
  • 960 GB
Note
Both the M.2 kit and drive bay 3 occupy PCIe slot 3 and therefore cannot be installed in the same system.

For a list of supported M.2 drives, see Lenovo ServerProven website.

Storage expansion
The server supports three 3.5-inch drive bays (two for optional), one 2.5-inch drive bay (optional), one ODD bay (optional).
  • Drive bay 0
    • 3.5-inch hard-disk drive or solid-state drive
  • Drive bay 1 (optional)
    • 2.5-inch hard-disk drive or solid-state drive
  • Drive bay 2 (optional)
    • 3.5-inch hard-disk drive or solid-state drive
  • Drive bay 3 (optional)
    • 3.5-inch hard-disk drive or solid-state drive
      Note
      Both the M.2 kit and drive bay 3 occupy PCIe slot 3 and therefore cannot be installed in the same system.
  • ODD drive bay (optional)
    • One 9mm slim SATA Optical disk drive

For a list of supported drives, see Lenovo ServerProven website.

Expansion slots
Three PCIe expansion slots are available:
  • PCIe slot 1: PCIe Gen4 x4, FH/HL, 25W
  • PCIe slot 2: PCIe Gen5 x16, FH/HL, 75W
  • PCIe slot 3: PCIe Gen4 x4, FH/HL, 25W
Note
Slot 1 and Slot 3 in the ST50 V3 are open-end design, which means that the slots can accept adapters with a longer edge connector than the physical length of the slot connector. For example, if a x8 adapter is installed in the x4 slot 3 of the server, half of the edge connector will not be connected to the slot. The adapter will still function, but performance will be impacted.
Integrated functions and I/O connectors
  • Lenovo XClarity Controller (XCC), which provides service processor control and monitoring functions, video controller, and remote keyboard, video, mouse, and remote drive capabilities.
  • Front connectors:
    • One USB 3.2 Gen 1 (5 Gbps) connector
    • One USB 2.0 connector with XCC mobile support
  • Rear connectors:
    • One serial port
    • One VGA connector
    • One XCC system management port (10/100/1000 Mbps RJ-45)
    • Two Ethernet connectors (Ethernet connector 1 shared with Lenovo XClarity Controller network connector)
    • Four USB 3.2 Gen 1 (5 Gbps) connectors
Note
The maximum video resolution is 1920 x 1200 at 60 Hz.
Network
  • Two 1 Gbps RJ45 Ethernet connectors
  • One 1 Gbps RJ45 Lenovo XClarity Controller network connector
Rear button
NMI button
RAID adapter
The following options are available for this server.
  • Hardware RAID (RAID level 0, 1, and 5)
    • ThinkSystem RAID 5350-8i PCIe 12Gb Adapter
  • Software RAID (RAID level 0, 1, and 5)
    • Intel VROC SATA RAID
