DELL PowerEdge R640 1U rack server 2× Xeon Gold 6134 3.2GHz 64GB DDR4 8× 1.2TB SAS H740P 4× 1GbE

PowerEdge R640 virtualization server

The Dell EMC PowerEdge R640 is a 1U rack server built for business workloads such as virtualization, databases, backups and application hosting. Two Intel Xeon Gold 6134 processors run at 3.20 GHz with Turbo Boost up to 3.70 GHz, delivering 16 cores in total. 64 GB of DDR4 ECC registered memory is installed across 24 slots, supporting up to 3 TB maximum capacity. Redundant hot-swap power supplies are included.

Suits dense virtualization; not for GPU compute

This configuration suits teams that need high core density and fast SAS storage in a single rack unit for virtual machine clusters or database instances. The 1U form factor limits expansion cards, so buyers who need GPU acceleration or additional PCIe devices should look at a larger chassis. Memory headroom remains for growth up to the 3 TB limit.

8× 1.2 TB SAS drives on H740P

Eight 1.2 TB 10K SAS drives connect through the Dell PERC H740P controller with 8 GB cache, providing hardware RAID for operating systems, applications, virtual machines and backups. The SAS interface delivers 12 Gb/s throughput for write-heavy workloads. Four onboard 1 GbE RJ45 ports handle network connectivity.
