DELL PowerEdge R640 1U rack server 2× Xeon Gold 6142 2.6GHz 16-core 256GB DDR4 8× 400GB SSD H730P

Dual-Socket 1U Rack Server

The Dell PowerEdge R640 is a 1U rack server built for dense scale-out deployments. It ships with two Intel Xeon Gold 6142 processors running at 2.6 GHz with 16 cores each. The system includes 256 GB of DDR4 2666 MHz registered ECC memory across eight 32 GB modules. Dual 750 W platinum redundant power supplies, iDRAC9 Enterprise, rails and a front bezel are included.

Compute Density Focus

This configuration suits workloads that demand high core counts and fast local storage in a single rack unit. The eight 400 GB SATA SSDs and PERC H730P controller with 2 GB cache support RAID 0, 1, 5, 6, 10, 50 and 60. Buyers who need more than 24 DIMM slots, additional drive bays beyond the eight 2.5-inch bays, or more than two processor sockets should evaluate other platforms.

DDR4 2666 MHz Memory Standard

The installed 256 GB uses DDR4 2666 MHz registered ECC modules; the platform accepts up to 3 TB across 24 slots. Only DDR4 memory is compatible — other DDR generations will not fit. Matching this memory type is the single specification that determines whether additional modules can be used.
