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.

Frågor om den här produkten

Should I pick the 10-bay 2.5-inch SAS configuration or a different drive count for the R650?

This unit ships with ten 600 GB 10K SAS drives filling every 2.5-inch bay, giving 6 TB raw capacity under the H755 RAID controller.

What does the 3.2 GHz turbo figure mean once the Xeon Gold 6338 is installed in this 1U chassis?

Each 32-core processor can lift from its 2.0 GHz base to 3.2 GHz when thermal headroom allows, boosting single-thread response for database and virtualization threads.

How does the OCP 3.0 10 GbE SFP+ card limit real-world throughput?

The Broadcom 57412 dual-port adapter caps each port at 10 Gb/s, so aggregate bandwidth tops out at 20 Gb/s across both SFP+ links.
