Compact 1U server with dual Xeon Silver 4316

The Dell PowerEdge R650xs is a 1U rack server fitted with two Intel Xeon Silver 4316 2.3 GHz 20-core processors, 64 GB of DDR4 memory and a PERC H745 RAID controller. Ten 1.8 TB SAS hard drives provide 18 TB of raw storage. Dual 1400 W power supplies and iDRAC9 Enterprise management are included, making the system ready for immediate deployment in virtualisation, cloud or dense compute workloads.

Suited for high-density virtualisation

Organisations running hypervisor clusters, database nodes or analytics platforms that benefit from 40 total cores and front-accessible SAS storage will find the configuration well matched. Buyers who require GPU acceleration, faster networking than 1 GbE, or larger memory capacity per socket should evaluate other platforms.

PERC H745 controller with 4 GB NV cache

The integrated Dell PERC H745 RAID controller supports RAID 0, 1, 5, 6, 10, 50 and 60 with a 4 GB non-volatile cache and battery backup. This specification determines the range of RAID levels and write-performance characteristics available for the ten installed SAS drives.

Questions about this item

What DDR4 memory speed must the existing modules run at to match the 2666MHz registered ECC DIMMs installed in this R650xs?

The server ships with 64GB of DDR4 2666MHz registered ECC memory in four 16GB modules. Any additional DIMMs should be 2666MHz registered ECC to maintain matched speeds across all 16 slots.

Will the PERC H745 controller manage the 10x 1.8TB 10K SAS drives alongside older SATA SSDs in the same 2.5" bays?

The H745 supports mixed SAS and SATA drives in the 10 front bays. The 10x 1.8TB 10K SAS 12Gb/s drives are pre-configured; SATA SSDs can be added to empty bays and managed in the same virtual disks.

How do I confirm the dual 1400W platinum power supplies are both active and redundant after racking the 1U server?

iDRAC9 Enterprise reports real-time PSU status. In the iDRAC web interface or front-panel LCD, verify both 1400W units show "OK" and "Redundant" — green LEDs on each supply confirm active load sharing.
