Dense 1U Dual-Socket Server

The Dell PowerEdge R640 is a 1U rack server built for dense scale-out data centre workloads. It ships with two Intel Xeon Gold 6142 processors running at 2.6 GHz with 16 cores each and 64 GB of DDR4 2666 MHz registered ECC memory across 24 DIMM slots.

Suited For Compute-Dense Racks.

This platform suits operators who need maximum CPU throughput in a single rack unit with redundant 750 W platinum power supplies and integrated 10 GbE plus 1 GbE networking. Buyers who need more than eight 2.5‑inch drive bays, additional PCIe expansion slots or GPU-accelerated compute should evaluate other form factors.

Eight 2.4 TB SAS Drives On H730P Controller

The storage subsystem provides eight 2.4 TB 10K SAS drives managed by a PERC H730P 2 GB controller supporting RAID 0/1/5/6/10/50/60 and pass-through modes, delivering high IOPS for database and virtualisation workloads.
