Dell PowerEdge R640 8x 2.5" 40-Core 2x Xeon Gold 6148 2.4GHz 512GB DDR4 8x 1TB SATA SSD X550-T4

Dual-socket Xeon Gold 6148 rack server

This 1U rackmount server delivers 40 cores across two Intel Xeon Gold 6148 processors running at 2.40GHz. It ships with 512GB of DDR4 memory and eight new 1TB SATA SSDs installed in the 2.5-inch drive bays. The H730P storage controller manages the array for virtualization, databases and business application hosting.

SATA SSD throughput and bay count limit storage

Eight 2.5-inch bays are populated with SATA solid-state drives, so sequential throughput is bound by the SATA interface rather than faster protocols. The H730P controller supports RAID levels for redundancy, but the bay count and drive interface set the practical ceiling for total capacity and IOPS in this chassis.

512GB DDR4 installed with 3TB maximum capacity

The system arrives with 512GB of DDR4 memory installed across the two processors and supports up to 3TB when fully populated. Buyers who need more memory than 512GB must add compatible DDR4 modules; those who require a different memory generation or larger out-of-the-box capacity cannot use this configuration.
