Dual Xeon 4310 storage server

The Supermicro SSG-640SP-E1CR60-G1 is a 4U rack system built for dense capacity workloads. Dual 12-core Intel Xeon Silver 4310 processors at 2.10 GHz provide 24 threads for parallel tasks. The chassis holds 256 GB of DDR4-3200 ECC memory across 16 slots with a 4 TB ceiling. Four 20 TB 3.5-inch SATA drives and a 960 GB M.2 NVMe boot drive ship installed.

Suits archive and backup workloads

This server suits teams that need massive raw capacity in a single 4U frame with hardware RAID via the Broadcom 3916 adapter supporting up to 240 devices. Dual onboard 10GbE RJ45 ports handle high-throughput replication. Buyers who need all-flash performance or GPU compute density should look elsewhere because the front bays target 3.5-inch mechanical drives and the platform lacks accelerator slots.

Straightforward rack integration

The unit slides into a standard 4U rack space and uses six hot-swap 8 cm fans for cooling redundancy. Dual 2000 W titanium power supplies share the load with hot-plug capability. Installation typically involves rack rails, power cords, and network cables. The most common issue is underestimating weight and airflow requirements for a fully populated 60-bay chassis.

Questions about this item

What network infrastructure is needed to use the onboard dual 10GbE RJ45 LAN ports?

A 10GbE-capable switch and Cat6a or better cabling are required to run the two onboard RJ45 ports at their rated speed.

Can the 16 internal SAS3 ports on the Broadcom 3916 RAID adapter also attach existing SATA drives?

Yes, the 12Gb/s SAS3 ports are backward compatible with 6Gb/s and 3Gb/s SATA drives, so older 3.5" or 2.5" SATA disks can be connected directly.

How can I verify that the 960GB M.2 NVMe boot drive is recognised after installation?

Enter the system BIOS or UEFI setup; the 80mm M.2 NVMe device should appear in the storage device list with its 960GB capacity shown.
