Purpose-built 1U server

The Dell PowerEdge R650xs is a 1U rack server equipped with two Intel Xeon Silver 4310 12-core processors running at 2.1GHz with 3.3GHz turbo. It ships with 128GB of DDR4 2666MHz registered ECC memory across eight modules. The system includes a PERC H745 RAID controller with 4GB NV cache and battery, ten 2.5-inch drive trays supporting SATA and SAS, dual 10GbE SFP+ networking, iDRAC9 Enterprise remote management, dual 1400W platinum power supplies, rails and a front bezel.

Ideal for dense virtualisation.

This configuration suits organisations consolidating virtual machines, running cloud infrastructure or hosting databases that benefit from high core counts and redundant power in a single rack unit. Buyers who need GPU acceleration for AI training or inference should look elsewhere, as the 1U chassis does not accommodate add-in cards. Teams requiring front-access NVMe storage must choose a different model, because the installed backplane and controller support only SATA and SAS drives.

Ten-bay SATA/SAS storage limit

The single specification that decides fit is the ten 2.5-inch trays wired for SATA and SAS behind the PERC H745 controller. If the deployment demands more than ten drives, NVMe performance or direct GPU attachment, this server cannot meet those requirements.

Questions about this item

What rack depth and rail kit are required to mount the 1U R650xs?

The server is a 1U rack unit and ships with Ready Rails for standard four-post racks; verify your rack depth matches the rail specification before installation.

In which slot does the PERC H745 controller install, and which cables connect it to the 10 front 2.5" drive bays?

The H745 plugs into the dedicated internal storage slot and uses the supplied mini-SAS cables to link the controller to the 10 front drive backplane.

When the PERC H745 battery reaches end of life, what is the replacement part?

The controller uses a 4 GB NV cache battery module; replace it with the Dell part number specified for the H745 to retain RAID cache protection.
