DELL PowerEdge R640 1U rack server 2x Xeon Gold 5118 2.3GHz 12C 512GB DDR4 8x 600GB SAS H730P

Dense dual-socket 1U compute node

The Dell PowerEdge R640 is a 1U rack server built around two Intel Xeon Gold 5118 processors, each running at 2.3 GHz with 12 cores. It ships with 512 GB of DDR4 2400 MHz registered ECC memory across 16 DIMM slots, a PERC H730P 2 GB SAS/SATA RAID controller, and eight 600 GB 10 K SAS drives in 2.5 inch bays. Dual 750 W platinum power supplies, iDRAC9 Enterprise, a quad-port 1 GbE and 10 GbE SFP+ network daughter card, rails and bezel complete the package.

Suits scale-out clusters and virtualization hosts

This configuration fits dense scale-out deployments, virtualization clusters and database workloads that benefit from 24 cores and 512 GB of memory in a single rack unit. The 12 Gb/s SAS backplane and PERC H730P with battery-backed cache support RAID 0, 1, 5, 6, 10, 50 and 60 for local redundancy. Buyers who need more than two processors, greater memory capacity than 512 GB, additional drive bays beyond eight 2.5 inch slots, or PCIe add-in cards for GPU or FPGA acceleration should evaluate larger platforms.

512 GB DDR4 memory ceiling

The installed 512 GB (16 x 32 GB) DDR4 2400 MHz registered ECC kit occupies 16 of 24 slots, leaving eight slots open for expansion up to the platform maximum of 3 TB. Memory type and speed are fixed to DDR4 2400 MHz; other DDR generations are physically and electrically incompatible. Verify your application’s memory footprint against this ceiling before ordering.
