Lenovo ThinkSystem SR650 V3 Server

Combining performance and flexibility, the SR650 V3 server is a great choice for enterprises of all sizes. The server offers a broad selection of drive and slot configurations and offers numerous high performance features. Outstanding reliability, availability, and serviceability (RAS) and high-efficiency design can improve your business environment and can help save operational costs.

Scalability and performance

The SR650 V3 offers numerous features to boost performance, improve scalability and reduce costs:

• Supports one or two fifth-generation Intel Xeon Processor Scalable processors
  • Up to 64 cores and 128 threads
  • Core speeds of up to 3.9 GHz
  • TDP ratings of up to 385 W
• Supports one or two fourth-generation Intel Xeon Processor Scalable processors
  • Up to 60 cores and 120 threads
  • Core speeds of up to 3.7 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 5600 MHz (5th Gen processors) or 4800 MHz (4th Gen processors)
  • Supports 2 DIMMs per channel operating at 4800 MHz (5th Gen processors) or 4400 MHz (4th Gen processors)
  • Using 256GB 3DS RDIMMs, the server supports up to 8TB of system memory
• Supports up to eight single-width GPUs or three double-wide GPUs, for substantial processing power in a 2U system.
• The server is Compute Express Linsk (CXL) v1.1 Ready. With CXL 1.1 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 40x 2.5-inch drive bays, by using combinations of front-accessible (up to 24 bays), mid bays (8 bays) and rear-accessible (8 bays).
• Supports 20x 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.
• 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 14x SATA drives using the onboard SATA controller (no additional adapter needed), enabling lower cost, high capacity storage solution for cold or archival storage workloads.

• Supports high-speed RAID controllers from Broadcom providing 12 Gb SAS connectivity to the drive backplanes. A variety of PCIe 3.0 and PCIe 4.0 RAID adapters are available.
• Supports up to two externally accessible 7mm hot-swap drives for operating system boot functions. Optional RAID-0 or RAID-1.
• Supports M.2 drives for convenient operating system boot functions. Available M.2 adapters support either one M.2 drive or two M.2 drives. Optional RAID-0 or RAID-1.
• Up to 12x PCIe slots (10x rear, 2x front), plus a slot dedicated to an OCP 3.0 adapter. 2.5-inch drive configurations also support an additional internal bay for a cabled RAID adapter or HBA.
• The server has a dedicated industry-standard OCP 3.0 small form factor (SFF) slot, 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.
