Dense 1U dual-socket server

The Dell PowerEdge R640 packs two Xeon Gold 6134 processors at 3.2 GHz with 8 cores each into a single rack unit. It ships with 64 GB of DDR4 registered ECC memory across 24 slots and eight 300 GB 10 K SAS drives on a PERC H730P controller. Dual 750 W platinum supplies and iDRAC9 Enterprise complete a ready-to-deploy dense compute node.

Suited for memory-heavy scale-out workloads

Virtualization clusters, database nodes and HPC front-ends that need high core counts and fast SAS storage in minimal rack space will fit this configuration. Buyers who need more than 3 TB of RAM, additional drive bays beyond the eight 2.5-inch slots, or GPU-accelerated compute should evaluate larger chassis options.

PERC H730P with 2 GB cache defines storage

The controller supports RAID 0, 1, 5, 6, 10, 50 and 60 plus pass-through mode at 12 Gb/s across SAS and SATA drives. This single component determines whether the eight installed 300 GB disks meet your performance and redundancy requirements.

Questions about this item

How do I replace the PERC H730P controller battery when it reaches end of life?

The H730P includes a 2GB cache backed by a replaceable battery module; swap it by releasing the controller latch, unplugging the old pack and inserting the new one.

Which component hits its thermal ceiling first when both Xeon Gold 6134 CPUs run at 3.7GHz turbo continuously?

The two 8-core processors share the 1U chassis airflow; sustained turbo loads push the CPU package temperature to the firmware throttle point before the 750W PSUs or memory do.

What is the typical power draw and acoustic profile when the server runs 24/7 with all eight 300GB SAS drives active?

Dual 750W Platinum supplies feed the system; idle draw sits near 285W and rises toward 350W under full drive and CPU load, while fan noise stays in the mid-50 dBA range.
