Scalability and performance

The ThinkSystem SR650 V4 offers numerous features to boost performance, improve scalability and reduce costs:

• Supports one or two Intel 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 Compute Express Link (CXL) memory DIMMs in an E3.S 2T form factor, up to 12x CXL DIMMs 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 high-performance 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 or data storage. 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.
• 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.

Availability and serviceability

The SR650 V4 provides many features to simplify serviceability and increase system uptime:

• Designed to run 24 hours a day, 7 days a week

• Proactive Platform Alerts (including PFA and SMART alerts): Processors, voltage regulators, memory, internal storage (SAS/SATA HDDs and SSDs, NVMe SSDs, M.2 storage, flash storage adapters), fans, power supplies, RAID controllers, server ambient and subcomponent temperatures. Alerts can be surfaced through the XClarity Controller to managers such as Lenovo XClarity Administrator, VMware vCenter, and Microsoft System Center. These proactive alerts let you take appropriate actions in advance of possible failure, thereby increasing server uptime and application availability.
• The built-in XClarity Controller continuously monitors system parameters, triggers alerts, and performs recovery actions in case of failures to minimize downtime.
• Built-in diagnostics in UEFI, using Lenovo XClarity Provisioning Manager, speed up troubleshooting tasks to reduce service time.

Energy efficiency

The SR650 V4 offers the following energy-efficiency features to save energy, reduce operational costs, and increase energy availability:

• The server supports advanced Lenovo Neptune Core direct-water cooling (DWC) capabilities, where heat from key components is removed from the rack and the data center using an open loop and coolant distribution units, resulting in lower energy costs:
• Processor Neptune Core Module uses liquid cooling to remove heat from the processors
• Compute Complex Neptune Core Module uses liquid cooling to remove heat from the processors, memory and voltage regulators
• Energy-efficient system board components help lower operational costs.
• High-efficiency power supplies with 80 PLUS Titanium certifications
• Solid-state drives (SSDs) consume as much as 80% less power than traditional spinning 2.5-inch HDDs.
• Support for Lenovo XClarity Energy Manager provides advanced data center power notification, analysis, and policy-based management to help achieve lower heat output and reduced cooling needs.
• The server uses hexagonal ventilation holes, which can be grouped more densely than round holes, providing more efficient airflow through the system and thus keeping your system cooler.
