DELL PowerEdge R650 1U rack server 2x Xeon Gold 6338 2.0GHz 32-core 64GB DDR4 10x 600GB SAS H755 2x 1400W PSU

Purpose-built 1U rack server

The Dell PowerEdge R650 is a 1U rack server designed for dense enterprise workloads such as virtualization and database management. It ships with two Intel Xeon Gold 6338 processors, each providing 32 cores at 2.0 GHz with a 3.2 GHz turbo frequency. The system includes 64 GB of DDR4 registered ECC memory across four 16 GB modules. Ten 600 GB 10K SAS drives and a PERC H755 RAID controller with 8 GB NV cache complete the storage subsystem. Dual 1400 W platinum power supplies and iDRAC9 Enterprise management are standard.

SAS 12 Gb/s storage ceiling

The ten 2.5-inch drive bays use a 12 Gb/s SAS interface backed by the H755 controller, which supports RAID levels 0, 1, 5, 6, 10, 50 and 60. This interface caps sequential throughput for the installed 10K drives, so workloads demanding sustained NVMe-class latency or higher IOPS will hit the bus limit. The controller’s 8 GB NV cache helps absorb bursts, but the underlying SAS lane speed remains the hard boundary for any drive population in this chassis. PCIe Gen4 slots are present for add-in cards, yet the front bays themselves stay on SAS.

Upgrade from older 1U platforms

This configuration replaces earlier 1U servers that relied on previous-generation Xeon Scalable CPUs and slower DDR4 speeds, delivering a substantial core-count and memory-bandwidth jump. The move is worthwhile when consolidation ratios demand 64 cores in a single rack unit and the workload fits within 64 GB of RAM and 6 TB of 10K SAS capacity. Buyers who need more memory slots, NVMe-only bays or higher single-thread frequency will find the R650’s fixed 1U layout and SAS backplane limiting.
