Dual Xeon Gold 5317 compute density

The Dell PowerEdge R650 is a 1U rack server fitted with two Intel Xeon Gold 5317 processors running at 3.0 GHz with a 3.6 GHz turbo frequency. Each chip provides twelve cores, giving twenty-four cores in total for parallel workloads. The system includes 256 GB of DDR4 2933 MHz registered ECC memory across eight 32 GB modules. Ten 1.8 TB 10K SAS drives connect through a PERC H755 controller with 8 GB NV cache and battery backup.

Redundant platinum power and thermal design

Two 1400 W platinum-efficiency power supplies operate in a hot-swap redundant configuration. The 1U chassis uses Dell's 15th generation thermal architecture to move air across the processors, memory and drive bays within a single rack unit. iDRAC 9 Enterprise provides out-of-band monitoring of temperatures, fan speeds and power draw without loading the host operating system. The front bezel and ready rails are included for standard rack installation.

Sustained throughput for virtualization

The PERC H755 controller supports RAID levels 0, 1, 5, 6, 10, 50 and 60, allowing the ten SAS drives to be arranged for capacity, redundancy or a mix of both. The Broadcom 57412 dual-port 10 GbE SFP+ OCP 3.0 adapter delivers consistent network bandwidth for storage traffic and virtual machine migration. Memory can be expanded to 2 TB across thirty-two DDR4 slots when workloads grow beyond the installed 256 GB. Builders needing more than ten drive bays or a different drive interface should consider other platforms.

Questions about this item

How do I install the 10 x 2.5" SAS drives in the 1U R650, and what step is commonly missed?

Slide each drive into the front hot-swap bays until the latch clicks; the step often missed is confirming the PERC H755 controller detects all 10 drives and creating the desired RAID volume before installing the OS.

What maintenance or replacement will the PERC H755 RAID controller need later?

The H755 includes an 8GB NV cache with a battery-backed module; plan to replace the cache battery every 3–5 years to preserve write-back performance and data protection during power loss.

What limit appears first when the dual Xeon Gold 5317 CPUs run sustained workloads in this 1U chassis?

Thermal headroom is the first constraint; the 1U form factor and 1400W PSUs cool the 3.0GHz 12-core processors, but prolonged turbo to 3.6GHz can trigger throttling if inlet air exceeds spec.
