Dual-processor 1U rack server

The Dell PowerEdge R650xs is a 1U rack server built for data-centre workloads that need high compute density in a single rack unit. Two Intel Xeon Gold 5317 processors supply 12 cores each at 3.0 GHz with 3.6 GHz turbo frequency, while 64 GB of registered ECC DDR4 memory provides a stable base for virtualization and database tasks.

SAS storage limits and RAID options

Eight 2.5-inch 1.8 TB SAS drives connect to the PERC H745 controller, which supports RAID 0, 1, 5, 6, 10, 50 and 60 with 4 GB of battery-backed cache. The SAS 12 Gb/s interface caps sequential throughput at the drive level, so mixed read and write workloads will not exceed the mechanical limits of 10 000 rpm disks. NVMe and SATA drives are not installed in this configuration.

Pre-installation checklist

Confirm the rack provides standard 1U spacing and that the included ready rails match your cabinet depth. Verify the facility can supply two 1400 W power circuits for redundant hot-swap operation. Ensure the operating system and hypervisor support the LGA 4189 socket and the H745 RAID driver stack before deployment.

Questions about this item

Should I choose the 1.8 TB SAS drives or look for a different capacity?

The server ships with eight 1.8 TB 10K SAS drives on a PERC H745 controller supporting RAID 0/1/5/6/10/50/60; this capacity suits mixed read/write workloads needing redundancy and speed in a 2.5" bay layout.

What does the 3.0 GHz base clock mean once the Xeon Gold 5317 is under load?

Each 12-core Xeon Gold 5317 runs at 3.0 GHz base and can reach 3.6 GHz turbo, giving two processors strong single-thread response and multi-thread throughput for virtualization or database tasks.

How does the H745 controller's 12 Gb/s SAS interface cap real-world drive performance?

The PERC H745 connects the 10K SAS drives at 12 Gb/s, so sustained throughput is limited by the mechanical drive speed rather than the controller link, while the 4 GB NV cache absorbs write bursts.
