Dell PowerEdge R660 specifications

The PowerEdge R660 is an upgrade from Dell's previous generation PowerEdge R650. This 1U rack server is suitable for all applications from general purpose to HCI/HPC. Key features include support for two processors (dual socket), 32 RDIMMs, and three graphics cards.

The biggest step forward for the R660 over the R650 is that it's based on Intel's "Sapphire Rapids" 4th generation Xeon Scalable processors. These new chips scale up to 56 points, use DDR5 memory and support Gen5 storage.

Storage configuration is also one of the advantages of this server. Traditional storage can scale up to ten 2.5-inch SAS/SATA drives, but it can also use Gen5 NVMe SSDs. Additionally, new backplane options include support for up to 16 E3.S (7mm) drives. There are also rear drive options for booting, including a new NVMe BOSS drive.
