Lenovo ThinkSystem SR650 V3 2U Rack Server
PRODUCT DESCRIPTION
Lenovo ThinkSystem SR650 V3 2U Rack Server (Configure-to-Order) - Local Warranty
2U, Dual-Socket Intel Xeon Performance
The Lenovo ThinkSystem SR650 V3 is a 2-socket 2U rack server. It takes one or two 5th Gen Intel Xeon Scalable processors with up to 64 cores each (or 4th Gen with up to 60 cores), and 32 TruDDR5 RDIMM slots for up to 8 TB of memory at up to 5600 MHz.
Storage and Expansion That Scale With the Workload
The chassis supports up to 20 x 3.5-inch or 40 x 2.5-inch hot-swap drive bays, up to 12 PCIe slots (10 rear, 2 front) plus an OCP 3.0 slot with a PCIe 5.0 x16 interface, and up to 3 double-wide or 8 single-wide GPUs, making it a fit for databases, virtualisation and cloud, VDI and AI.
Managed and Secured by Lenovo XClarity
Every SR650 V3 includes the Lenovo XClarity Controller 2 (XCC2) for out-of-band management, works with XClarity Administrator, and is protected by Platform Firmware Resiliency, TPM 2.0 and a chassis intrusion switch.

How to Configure Your Server — Sizing Checklist
Servers are built to order. Answer the questions below so we can size the right configuration for you.
Step 1: Hardware Requirements
- Which server form factor do you need: tower or rackmount?
- How many CPU cores, how much RAM and how much usable storage capacity do you require?
- How many processors: single-socket (1S), dual-socket (2S) or four-socket (4S)?
- Which RAID configuration do you need? Any specific HDD or SSD type, such as 7.2K or 10K rpm drives?
- Which network interface is required: 1GbE Base-T, SFP+ or Fibre Channel?
- How many years of maintenance support do you need? (Minimum 3 years)
Step 2: Deployment & Services
- How many server units are required?
- Will you run virtual machine workloads? Do you need a VMware licence, or Windows Server with Hyper-V?
- How do you store data today? Do you have existing NAS or SAN storage?
- How do you back up today? Would you like a backup proposal, such as an IDPA 8TB appliance?
- Do you require burn-in test services?
- Do you need hard disk retention services?
