Lenovo ThinkSystem ST650 V3 Tower Server
PRODUCT DESCRIPTION
Lenovo ThinkSystem ST650 V3 Tower Server (Configure-to-Order) - Local Warranty
Dual-Socket Intel Xeon in a Tower
The Lenovo ThinkSystem ST650 V3 is a 2-socket tower server, also convertible to a 4U rack, for one or two 5th Gen or 4th Gen Intel Xeon Scalable processors with up to 32 cores each. 32 DDR5 DIMM slots take up to 4 TB of memory at up to 5600 MHz with 5th Gen Xeon.
Enterprise Storage and Expansion
Up to 32 x 2.5-inch or 16 x 3.5-inch hot-swap drives (up to 24 NVMe), two 5.25-inch media bays for optical or tape, nine PCIe slots (five PCIe 5.0, four PCIe 4.0) and support for up to four double-wide GPUs. Two onboard 10GBASE-T ports come standard.
Managed by Lenovo XClarity
XClarity Controller 2 (XCC2) provides embedded out-of-band management, and a Root of Trust module with TPM 2.0 protects the firmware. Hot-swap drives, power supplies and fans keep maintenance quick for branch offices and server rooms.

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?
