Dual-Socket 1U Server

The Dell PowerEdge R640 is a 1U rack server with two Intel Xeon Gold 6148 processors running at 2.40 GHz. Each processor provides 20 cores for a total of 40 cores. The system includes 128 GB of DDR4 2666 MHz registered ECC memory across 8 modules. It is built for dense scale-out data center deployments.

Compute Density vs Expansion

This server suits workloads that need high core counts in a single rack unit, such as virtualisation clusters or database nodes. The 8-bay 2.5-inch drive cage and single PCIe daughter card limit internal storage expansion and additional network adapters. Buyers who need more drive bays or extra add-in cards should look at a 2U platform.

PERC H730P RAID Controller

The installed Dell PERC H730P 2 GB controller manages the 8 included 2.4 TB 10K SAS drives and supports RAID 0, 1, 5, 6, 10, 50 and 60 plus pass-through mode. This controller determines which drive configurations and protection levels are available. Verify that its RAID feature set matches the storage topology required for the target application.
