Compact 1U rack server for virtualization

The Dell PowerEdge R650xs fits two Intel Xeon Gold 6338 processors in a single rack unit, delivering 32 cores at 2.0 GHz with a 3.2 GHz turbo frequency. It ships with 128 GB of DDR4 3200 MHz registered ECC memory across eight DIMM slots. The platform targets virtualization, cloud infrastructure and high-performance computing workloads that demand high core density in minimal space.

Storage limited to eight 2.5-inch SAS bays

Eight 600 GB 10K SAS drives connect through a PERC H745 controller with 4 GB NV cache and battery backup, supporting RAID 0, 1, 5, 6, 10, 50 and 60. The 1U chassis provides no room for additional internal drives beyond the front-accessible bays. Builders who need more storage capacity or NVMe acceleration must use external arrays or a different chassis.

Dual 1400 W platinum power supplies define

Two hot-swap 1400 W platinum-efficiency units supply redundant power for the fully populated configuration. The server includes a Broadcom 57412 dual-port 10 GbE SFP+ OCP 3.0 card and iDRAC9 Enterprise for remote management. Buyers who require GPU acceleration or more than two processors cannot expand this platform.

Questions about this item

Should I pick the 128 GB DDR4 3200 MHz configuration or expand to the 1 TB maximum?

The server ships with 128 GB installed across eight 16 GB registered ECC modules running at 3200 MT/s; sixteen DDR4 slots allow growth to 1 TB if your workloads demand more capacity.

How does the 3.2 GHz turbo frequency behave when both Xeon Gold 6338 CPUs are fully loaded?

Each Gold 6338 offers 32 cores at a 2.0 GHz base clock and can reach 3.2 GHz turbo; sustained all-core speeds depend on the thermal headroom provided by the 1U chassis and the 1400 W platinum power supplies.

What RAID levels does the PERC H745 controller support and how does the 12 Gb/s SAS backplane limit throughput?

The H745 handles RAID 0, 1, 5, 6, 10, 50 and 60 with 4 GB NV cache; eight 600 GB 10 K SAS drives connect at 12 Gb/s each, so aggregate bandwidth is capped by the backplane and drive count.
