Dense 1U dual-socket server

The Dell PowerEdge R640 packs two Intel Xeon Gold 6148 processors, each with 20 cores at 2.4 GHz and a 3.7 GHz turbo, into a single rack unit. It ships with 512 GB of DDR4 2666 MHz registered ECC memory across 16 slots, leaving room to grow toward the 3 TB maximum.

Suits compute-dense workloads

This configuration targets virtualization clusters, database nodes and high-performance computing tasks that benefit from 40 total cores and large memory capacity in minimal rack space. Buyers who need more drive bays than the eight 2.5-inch slots provide, or who require a different storage controller feature set, should evaluate other platforms.

Eight 400 GB SATA SSDs on H730P

Storage is delivered by eight enterprise 400 GB SATA SSDs managed by the PERC H730P 2 GB controller, which supports RAID 0, 1, 5, 6, 10, 50, 60 and pass-through modes. This drive count and controller combination determines usable capacity, redundancy options and I/O performance for the intended workload.
