Purpose-built virtualization server

The Dell PowerEdge R640 is a 1U rack server designed for business workloads such as file storage, virtualization, databases and application hosting. Dual Intel Xeon Bronze 3106 processors deliver 32 virtual threads at 1.7GHz to run multiple services simultaneously. With 384GB of DDR4 memory installed across 24 DIMM slots, the system supports dense virtual machine deployments and data-heavy applications. It targets IT teams that need a compact, redundant platform for core infrastructure tasks.

Chassis, power and connectivity

A 1U rackmount chassis houses redundant 750W hot-swap power supplies for continuous uptime. Eight 2.5-inch hot-plug drive bays accept SAS or SATA drives, while the integrated H730 controller manages RAID 0, 1, 5, 6, 10, 50 and 60 arrays. Networking starts with a four-port 1GbE daughter card, with optional 10GbE upgrades available. Three PCIe Gen3 x16 slots provide room for additional controllers or accelerators, and iDRAC9 with Lifecycle Controller enables remote firmware updates and hardware monitoring.

Memory ceiling decides fit

The installed 384GB matches the listed maximum memory capacity, leaving no headroom for future expansion without replacing modules. Buyers who anticipate growth beyond this limit or who require persistent memory options should evaluate a different configuration. The 24 DIMM slots are fully populated to reach this total, so any upgrade path requires module replacement rather than simple addition.

Questions about this item

What PCIe generation do the three x16 slots use, and what bandwidth limit does that impose on add-in cards?

The three slots are PCIe Gen3 x16, so each slot tops out at roughly 16 GB/s per direction; cards that need Gen4 or Gen5 speeds will run at Gen3 rates.

What are the exact rack dimensions and weight I must plan for when mounting this 1U server?

The chassis measures 28.17 inches deep, 17.09 inches wide, 3.42 inches high and weighs 63 lbs, so allow that depth plus cable clearance in a standard 19-inch rack.

How do I install the CPUs and memory without bending socket pins or populating the wrong DIMM channels?

Open the air shroud, lift each socket lever, align the triangle on the Xeon Bronze 3106 with the socket key, lower the lever, then fill the 24 DDR4 slots 12 per processor following the silkscreened channel order.
