Dense 1U dual-socket server

The Dell PowerEdge R640 is a 1U rack server fitted with two Intel Xeon Gold 6134 processors running at 3.2 GHz with eight cores each. It ships with 768 GB of DDR4 2666 MHz registered ECC memory across 24 slots and a Dell PERC H730P 2 GB controller managing two 400 GB SATA SSDs in eight 2.5-inch bays. Redundant 750 W platinum power supplies and iDRAC 9 Enterprise remote management complete the package.

Suits scale-out workloads.

This configuration suits dense scale-out data centre tasks that benefit from dual-socket compute and integrated 1 GbE and 10 Gb SFP+ networking. Buyers who need more than eight 2.5-inch drive bays should look elsewhere. Workloads requiring a different storage interface than SATA or SAS are not addressed by this backplane.

PERC H730P RAID flexibility decides fit

The PERC H730P controller supports RAID 0, 1, 5, 6, 10, 50 and 60 plus pass-through mode with a 2 GB cache and battery backup. That breadth of RAID levels is the single specification that determines whether the storage topology matches the application.

Questions about this item

What rack width and rail kit does the 1U R640 require for mounting?

The server is a 1U rack unit that ships with ready rails for standard cabinets; the rail kit is included in the box.

How are the two Xeon Gold 6134 processors and 24 DDR4 DIMMs installed, and what step is often missed?

Both LGA 3647 sockets are populated from the factory and all 24 slots are filled with 32 GB modules; the common oversight is forgetting to enable the H730P controller battery in BIOS before creating RAID volumes.

Which components in the R640 are hot-swappable and will need replacement over time?

The two 750 W power supplies and the eight 2.5-inch drive bays support hot-swap replacement; the PERC H730P battery and system fans are also field-replaceable.
