Original ThinkSystem SR650 V4 2U Rack Server

Specifications:

* Supports one or two Xeon 6700-series or 6500-series processors with Performance-cores (Pcores)
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.
*Support for Compute Express Link (CXL) memory modules in an E3.S 2T form factor, up to 12x CXL
modules with two processors. 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.
*Supports up to 10x single-width GPUs or 2x double-wide GPUs, for substantial processing power in a
2U system. For support for 4x double-wide GPUs, consider the ThinkSystem SR650a V4 server.
Supports up to 40x 2.5-inch drive bays, by using combinations of front-accessible (up to 24 hot-swap
bays), mid bays (8 simple-swap bays) and rear-accessible (8 hot-swap bays).
*Supports 36x 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 up to 16x 3.5-inch drive bays for lower-cost high-capacity HDD storage. 2.5-inch and 3.5-
inch drive bays can be mixed if desired.
*Support for up to 32x E3.S 1T NVMe drives, a new form factor drive for high-density and highperformance storage.
*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 10x PCIe slots (rear accessible), plus two slots dedicated to OCP 3.0 adapters. 2.5-inch drive
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.
