Dense compute for virtualization and databases

The PowerEdge R650 packs two Intel Xeon Silver 4316 processors, each with 20 cores running at 2.3 GHz and a 3.4 GHz turbo, into a 1U rack chassis. With 1 TB of DDR4 2666 MHz registered ECC memory installed across 32 DIMM slots, it targets dense virtualization, database clusters and high-performance computing workloads.

Front-access storage and quad 1 GbE networking

Ten 2.5-inch hot-swap trays accept SATA and SAS drives behind a tool-less bezel, while the PERC H755 controller with 8 GB NV cache supports RAID 0, 1, 5, 6, 10, 50 and 60. A Broadcom 5720 OCP 3.0 card delivers four 1 GbE ports, and iDRAC9 Enterprise provides dedicated out-of-band management over the same rack footprint.

Redundant platinum power keeps thermals steady

Dual 1400 W platinum-efficiency power supplies share load and allow hot replacement without downtime. The 1U airflow design moves air front-to-rear across both CPU sockets and memory banks, maintaining stable temperatures under sustained multi-core loads while fan speeds adjust to actual thermal demand rather than fixed curves.

Questions about this item

What storage interface and RAID levels does the PERC H755 controller support?

The PERC H755 controller provides eight internal lanes for SATA and SAS drives and supports RAID 0, 1, 5, 6, 10, 50 and 60 with 8 GB of NV cache and a battery backup.

What are the drive bay dimensions and tray count for the R650 chassis?

The 1U chassis holds ten front-accessible 2.5-inch hot-swap trays for SAS or SATA drives.

How do you install the server into a rack and which step is most often missed?

Mount the supplied ReadyRails sliding rails to the rack posts, slide the server onto the rails until it locks, then secure the front bezel and connect both 1400 W power supplies; the step most often missed is engaging the rail latch before releasing the server weight.
