Dense 1U compute node

The Dell PowerEdge R640 is a dual-socket 1U rack server built for scale-out workloads. Two Xeon Silver 4116 processors deliver 24 cores at 2.1 GHz with 3.0 GHz turbo. 128 GB of DDR4 registered ECC memory occupies eight of the 24 available slots. Eight 400 GB SATA SSDs connect through a PERC H730P controller with 2 GB cache and battery backup.

Virtualisation hosts, not GPU farms

This configuration suits hypervisor clusters, database nodes and high-density web tiers that benefit from dual 10 GbE SFP+ ports and redundant 750 W platinum supplies. Buyers who need GPU acceleration or more than eight drive bays in a single 1U chassis should evaluate alternative platforms. The installed SATA SSDs address read-heavy workloads; write-intensive applications may require different media.

Eight-bay 2.5" front storage limit

The chassis provides exactly eight hot-swap 2.5" bays, all populated with 400 GB SATA SSDs in this build. Expansion beyond eight drives demands external enclosures or a different server form factor. The PERC H730P supports RAID 0, 1, 5, 6, 10, 50 and 60 plus pass-through mode for software-defined storage stacks.

Questions about this item

What rack depth and rail kit does the 1U PowerEdge R640 need?

The server is a 1U rack unit and ships with ready rails for standard four-post racks.

How are the two Xeon Silver 4116 processors and 128 GB DDR4 installed, and what step is often missed?

Both CPUs come pre-installed in the LGA 3647 sockets; the eight 16 GB DDR4 modules fill half the 24 slots — populate remaining slots in matched pairs per channel.

Which drive and battery components will need replacement over time?

The eight 400 GB SATA SSDs and the PERC H730P 2 GB controller battery are the primary field-replaceable parts.
