1U Rack Server for General Purpose Workloads

The Lenovo ThinkSystem SR635 is a 1U rackmount server built for general purpose workloads. It ships with a single AMD EPYC 7203P processor running at 2.80 GHz and 64 GB of TruDDR4 memory. The chassis includes a slide rail kit and power cord for immediate rack integration. Certified operating systems include Windows Server and major Linux distributions.

Single Processor Configuration Limits Expansion

This model supports a maximum of one processor, so the installed EPYC 7203P defines the total compute capacity. Memory can scale to 1 TB across 16 DIMM slots, but CPU performance cannot be increased by adding a second socket. The ASPEED AST2500 graphics controller provides basic management video output only.

Suits Single Socket Deployments Not Dual CPU Needs

Organisations running single threaded applications or virtualised environments that fit within one EPYC socket will find this configuration efficient. Buyers who need dual processor performance or higher core counts from two CPUs should look at platforms that support two sockets. The 1U form factor also limits internal drive bays compared to larger chassis.

Questions about this item

How does the 2.80 GHz EPYC 7203P perform once installed in the SR635?

The single 7203P runs at 2.80 GHz base clock and handles general-purpose workloads within the 1U chassis without a second socket option.

What interface does the ASPEED AST2500 GPU use and what does it limit?

The AST2500 provides basic 2D video output for remote management consoles and does not support 3D acceleration or GPU compute tasks.

What physical space and mounting hardware does the 1U rack server need?

It occupies 1.7" height, 17.3" width, 29.7" depth and includes a slide rail kit for standard 19-inch rack mounting.
