DELL PowerEdge R650 1U rack server 2x Xeon Gold 5317 3.0GHz 12-core 256GB DDR4 10x 1.92TB SSD H755

Compact 1U rack server for dense virtualization

The Dell PowerEdge R650 packs two Intel Xeon Gold 5317 processors, each with 12 cores running at 3.0GHz and 3.6GHz turbo, into a single rack unit. With 256GB of DDR4 2933MHz ECC memory installed across 32 DIMM slots, it targets organisations running virtualised workloads, databases or private cloud clusters that demand high compute density. The system includes a PERC H755 RAID controller with 8GB NV cache and a dual-port 10GbE SFP+ OCP 3.0 network card. iDRAC9 Enterprise provides comprehensive remote management out of the box.

Tool-less rails and hot-swap components simplify

Ready Rails and a front bezel ship with the server, allowing one-person rack mounting without tools. Ten 2.5-inch drive bays and two 1400W platinum power supplies are hot-swappable, so failed drives or PSUs can be replaced while the system stays online. The PERC H755 supports RAID 0, 1, 5, 6, 10, 50 and 60; plan the array layout before loading data because changing RAID levels later requires a full rebuild. Memory population rules for dual-socket 3rd Gen Xeon Scalable platforms are specific — follow the documented channel order to avoid boot failures.

1U height limits expansion cards

The 1U form factor restricts PCIe add-in cards to low-profile halves, so full-height GPUs or additional NICs will not fit. Ten SATA SSDs saturate the backplane bandwidth, leaving no room for SAS or NVMe drives without a different chassis. Dual 1400W supplies provide redundancy but draw significant current; verify PDU capacity and circuit ratings before installation. Maximum memory capacity is 2TB, yet the 32 slots fill quickly with 32GB modules, so future upgrades may require replacing existing DIMMs rather than adding to empty slots.
