The ThinkSystem ST650 V2 is an enterprise-grade tower server with support for hot-swap power supplies, fans, and drives. It also offers full support of Lenovo XClarity Administrator for comprehensive systems management and includes the UEFI-based Lenovo XClarity Provisioning Manager for system setup and diagnosis, and the Lenovo XClarity Controller management processor for ongoing systems management and alerting. These tools make the ST650 V2 easy to deploy, integrate, service, and manage.

The ST650 V2 is a very storage-rich tower offering, supporting up to 32x 2.5-inch drives or up to 16x 3.5-inch drives. The tower server can also be converted to a 4U rack server if needed.

The ThinkSystem ST650 V2 is a high-performance dual-socket tower server based on the third-generation Intel Xeon Scalable processors, supporting a wide range of processors to suit a wide range of budgets and application requirements.

Scalability and performance

The ST650 V2 offers numerous features to boost performance, improve scalability and reduce costs:

• Supports one or two third-generation Intel Xeon Processor Scalable processors
  • Up to 36 cores and 72 threads
  • Core speeds of up to 3.6 GHz
  • TDP ratings of up to 250W
• Support for up to 32 TruDDR4 memory DIMMs operating at up to 3200 MHz means you have the fastest available memory subsystem.
• Supports configurations of 2 DIMMs per channel to operate at the 3200 MHz rated speed of the memory DIMMs.
• Using 128GB 3DS RDIMMs, the server supports up to 4TB of system memory.
• Supports the new Intel Optane Persistent Memory 200 Series for advanced in-memory database applications, dense-virtualization; up to 16 PMem Modules can be installed in conjunction with regular system memory.
• Supports up to eight single-width GPUs or four double-wide GPUs, for substantial processing power in a tower system.
• Supports a variety of front-accessible drive bays:
  • Up to 32x 2.5-inch hot-swap drive bays with two 5.25-inch media bays
  • Up to 12x 3.5-inch hot-swap drive bays with two 5.25-inch media bays
  • Up to 16x 3.5-inch hot-swap drive bays without the media bays
  • Up to 12x 3.5-inch simple-swap drive bays with two 5.25-inch media bays
• Supports up to 16x NVMe drives to maximize drive I/O performance, in terms of throughput, bandwidth, and latency.
• Supports up to 12x SATA drives using the onboard SATA controller (no additional adapter needed), enabling lower cost, high capacity storage solution.

• 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, including compact form factor adapters that are cabled and don’t occupy a PCIe slot.
• Supports M.2 drives for convenient operating system boot functions or data storage. Available M.2 adapters support either one M.2 drive or two M.2 drives in a RAID 1 configuration for performance and reliability.
• The server has two integrated 10 GbE 10GBASE-T ports with support for additional networking using adapter cards.
• The server offers PCI Express 4.0 I/O expansion capabilities that doubles the theoretical maximum bandwidth of PCIe 3.0 (16GT/s in each direction for PCIe 4.0, compared to 8 GT/s with PCIe 3.0). A PCIe 4.0 x16 slot provides 64 GB/s bandwidth, enough to support a 200GbE network connection.
• Up to nine PCIe slots, eight of which are PCIe 4.0 and are standard.
