Dual-socket 1U server for scale-out density

The Dell PowerEdge R640 packs two Intel Xeon Gold 6134 processors and 256 GB of DDR4 registered ECC memory into a single rack unit. Eight 800 GB SATA SSDs sit behind a PERC H730P controller with RAID support. Dual 750 W platinum power supplies and iDRAC 9 Enterprise management complete the package.

Suits dense virtualization and database clusters

Buyers who need more than 24 memory slots, additional drive bays beyond eight 2.5 inch trays, or a different network interface should evaluate larger platforms. The fixed 1U height and maximum two-processor limit also rule out workloads that scale beyond dual-socket configurations.

256 GB DDR4 registered ECC across 24 slots

This memory capacity and slot count determine how many virtual machines or in-memory datasets fit in a single node. Confirm the total RAM requirement against the 24 DIMM ceiling before ordering.

Questions about this item

How do I verify the H730P RAID controller is managing all eight 800GB SSDs correctly after setup?

Open the PERC H730P BIOS utility or iDRAC9 Enterprise interface; both show each 2.5-inch SATA SSD, the configured RAID level and battery-backed cache status.

What components come installed and which must be purchased separately for this R640?

The unit ships with two Xeon Gold 6134 CPUs, 256GB DDR4 in eight 32GB modules, eight 800GB SATA SSDs, H730P controller, X520/I350 quad-port NIC, iDRAC9 Enterprise, dual 750W PSUs, rails and bezel; additional memory or drives are optional.

Should I choose a configuration with more than 256GB DDR4 or larger SSDs for this model?

The board supports up to 3TB across 24 DDR4 slots and the eight 2.5-inch bays accept larger SATA SSDs, so select higher capacity only if your workload demands it.
