1U Dual-Socket Rack Server

The Dell PowerEdge R650xs is a 1U rack server built for dense compute environments. It ships with two Intel Xeon Silver 4316 processors running at 2.3 GHz with a 3.4 GHz turbo frequency. Each CPU provides 20 cores, giving 40 cores total across the system. The platform uses the LGA 4189 socket and supports a maximum of two processors.

Suited For Virtualisation And Dense Storage

This configuration suits teams running virtualisation clusters, database workloads or high-performance computing jobs that benefit from 128 GB of DDR4 2666 MHz registered ECC memory across eight DIMM slots. The eight 1.92 TB SATA SSDs behind a PERC H745 controller with 4 GB NV cache deliver high-capacity redundant storage. Buyers who need GPU acceleration, NVMe boot drives or more than 1 TB of memory should evaluate other platforms.

PERC H745 RAID Controller With 4 GB Cache

The storage subsystem centres on the Dell PERC H745 front RAID controller equipped with 4 GB of non-volatile cache and a battery backup unit. It supports RAID levels 0, 1, 5, 6, 10, 50 and 60 across the eight 2.5-inch drive bays. This controller choice determines the RAID flexibility and cache protection available for the installed SATA SSDs.

Questions about this item

What RAID levels does the H745 controller support and what practical limit does its SATA 6Gb/s interface impose?

The H745 supports RAID 0, 1, 5, 6, 10, 50 and 60; each of the eight 1.92TB SATA SSDs is limited to the SATA 6Gb/s link speed.

What physical mounting hardware is included for rack installation?

The package includes Dell Ready Rails sliding rails and a front bezel for standard rack mounting.

How is the H745 RAID controller installed and what step is commonly missed?

The H745 is a front-mounted controller that plugs into the dedicated front storage slot; the step often missed is connecting its 4GB NV cache battery before closing the chassis.
