ThinkSystem SR655 V3 — FAQs

Why choose the single-socket SR655 V3 over a dual-socket server?

Modern AMD EPYC delivers up to 160 cores and 12 memory channels from one socket, so the SR655 V3 gives you high core counts and huge storage/PCIe capacity while avoiding dual-socket licensing and NUMA overhead — ideal for storage-defined and per-core-licensed workloads.

How much storage does the SR655 V3 hold?

Up to 32× 2.5″ hot-swap drives across front, middle and rear zones (31 bay layouts), or up to 20× 3.5″. Maximum internal capacity reaches into the multi-petabyte range with high-capacity NVMe SSDs.

Can it run GPUs?

Yes — up to 8 single-width or 3 double-width GPUs, alongside up to 10 PCIe slots (9 PCIe 5.0-capable) and a dedicated OCP 3.0 network slot.
