Original ThinkSystem SR650a V4 2U Rack Server

Specifications:

• Supports one or two Xeon 6700-series or 6500-series processors with Performance-cores (P-cores)
  • Up to 86 cores and 172 threads
  • Core speeds of up to 4 GHz
  • TDP ratings of up to 350 W
• Support for DDR5 memory DIMMs to maximize the performance of the memory subsystem:
  • Up to 32 DDR5 memory DIMMs, 16 DIMMs per processor
  • 8 memory channels per processor (2 DIMMs per channel)
  • Supports 1 DIMM per channel operating at 6400 MHz
  • Supports 2 DIMMs per channel operating at 5200 MHz
  • Using 256GB 3D RDIMMs, the server supports up to 8TB of system memory
• Support for MRDIMMs for increased memory bandwidth with memory bus speeds of up to 8000 MHz.
• Supports up to 4x double-wide GPUs or 8x single-wide GPUs, at the front of the server, for substantial processing power in a 2U system
  • 2x H200 NVL 600W GPUs
  • 4x L40S 350W GPUs
  • 8x L4 single-wide GPUs
• Supports up to 8x 2.5-inch SAS/SATA, NVMe or AnyBay hot-swap drive bays or 8x E3.S 1T NVMe hot-swap drives for local storage.
• Supports 8x NVMe drives without oversubscription of PCIe lanes (1:1 connectivity). The use of NVMe drives maximizes drive I/O performance, in terms of throughput and latency.
• Supports high-speed RAID controllers providing 12 Gb SAS connectivity to the drive backplanes. A variety of PCIe 3.0 and PCIe 4.0 RAID adapters are available.
• Supports M.2 drives for convenient operating system boot functions. M.2 drives can be internally mounted or can be mounted at the front or rear of the server as hot-swap drives. Optional RAID-0 or RAID-1.
• Up to 8x PCIe slots (front accessible) for GPUs and 6x PCIe slots (rear accessible) for other PCIe adapters, plus two slots dedicated to OCP 3.0 adapters. Some configurations also support an additional internal bay for a cabled RAID adapter or HBA.
• The server has up to two dedicated industry-standard OCP 3.0 slots supporting a variety of Ethernet network adapters. A simple-swap mechanism with a thumbscrew and pull-tab enables tool-less installation and removal of the adapter. The adapter supports shared BMC network sideband connectivity to enable out-of-band systems management.
• The server 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 Gen 5, compared to 16 GT/s with PCIe Gen 4 and 8 GT/s with PCIe Gen 3). A PCIe 5.0 x16 slot provides 128 GB/s bandwidth, enough to support a dual-port 200GbE network connection or a single-port 400GbE connection.
