Purpose-built density

The Dell PowerEdge R640 is a 1U rackmount server configured with two Intel Xeon Gold 6148 processors running at 2.40 GHz, delivering 40 cores in total. It targets organisations that need high core density for virtualisation, database hosting, or multi-tenant application workloads in a compact footprint.

Thermal and power profile

Dual processors and 192 GB of DDR4 memory draw sustained power under load, so the chassis relies on forced-air cooling with redundant fans to maintain stable inlet temperatures. Acoustic output is typical for a 1U rack server and suits data-centre aisles rather than office environments.

Storage controller constraint

The integrated H730P RAID controller manages the ten 2.5-inch drive bays, eight of which are NVMe-capable, and it currently presents ten 1 TB SATA SSDs in a single array. Buyers who need direct NVMe passthrough or a different RAID level must verify controller firmware support before deployment.

Questions about this item

How do I install the 10x 1TB SATA SSDs into the 2.5" bays and what step is often missed?

Slide each drive into a 2.5" bay until the carrier clicks, then use the H730P controller BIOS to create a virtual disk before the OS sees the array.

What maintenance or replacement will the 192GB DDR4 memory need later?

DDR4 modules are solid-state and require no scheduled replacement; only add more sticks up to the 3TB limit if workloads grow.

What limit appears first when the 2x Xeon Gold 6148 CPUs run sustained loads?

The 40 total cores across both sockets reach full utilisation before memory bandwidth or the H730P controller saturates.
