DELL PowerEdge R650 10x 2.5" 1U 2x Xeon Silver 4316 2.3GHz 768GB DDR4 H755 10x 600GB SAS 5720 iDRAC9 2x 1400W

1U 10-bay rack server for dense enterprise workloads

This 1U Dell PowerEdge R650 fits ten 2.5-inch drives in a single rack unit and ships with two Intel Xeon Silver 4316 processors. Each CPU provides 20 cores at 2.3 GHz with a 3.4 GHz turbo frequency, giving 40 cores total for virtualization, database, or private cloud tasks. The system includes 768 GB of DDR4-2666 registered ECC memory across 24 slots and dual 1400 W platinum power supplies for redundancy. It is built for organisations that need maximum compute density in minimal rack space.

SAS 12 Gb/s backplane limits drive speed and count

The ten front bays connect through a 12 Gb/s SAS backplane to the PERC H755 RAID controller with 8 GB NV cache. Only SAS and SATA drives are supported on this backplane; NVMe drives cannot be used in these bays. RAID levels 0, 1, 5, 6, 10, 50, and 60 are available, but the total number of drives is fixed at ten 2.5-inch devices. Buyers who need more than ten drives or NVMe performance in the front bays should look at a different chassis.

768 GB DDR4-2666 decides memory capacity today

The server arrives with 768 GB installed across 24 DIMM slots, leaving eight slots open for expansion up to the 2 TB platform maximum. All memory is DDR4-2666 registered ECC; no other DDR generation is compatible. Buyers who need more than 768 GB immediately must purchase additional DDR4-2666 modules, while those who require a different memory speed or generation cannot use this system.
