Dell PowerEdge R640 1U server

The Dell PowerEdge R640 is a 1U rack server built for business workloads such as file storage, virtualization, databases, backups and application hosting. It ships with dual Intel Xeon Bronze 3106 eight-core processors running at 1.7GHz and 32GB of DDR4 memory. Redundant hot-swap 750W power supplies and an H730 RAID controller with 2GB cache simplify setup and day-to-day management.

IT teams running virtualised workloads

Organisations that need dependable performance for multiple virtual machines, data-heavy applications or mixed business services will find the dual-socket design and 24 DIMM slots well suited. Buyers who require higher single-thread speed, GPU compute or more than 32GB of memory as delivered should evaluate other configurations.

Eight 2.5-inch hot-plug drive bays

The chassis supports up to eight 2.5-inch hot-plug SAS or SATA drives with RAID 0, 1, 5, 6, 10, 50 and 60 levels on the H730 controller. Maximum raw capacity reaches 64TB. Three PCIe Gen3 x16 slots and a 1GbE quad-port daughter card provide expansion for storage, networking or accelerator cards.

Questions about this item

How deep is the rack space needed for this 1U server?

The chassis measures 28.17 inches deep, so the rack must provide at least that much usable depth plus cable clearance at the rear.

Which steps are required to install the CPUs and memory correctly?

Open the top cover, lift the processor sockets' load plates, align each Xeon Bronze 3106 using the notches, close the load plates, then populate the 24 DIMM slots evenly across the 12 slots per processor.

When and how should the redundant power supplies be replaced?

Each 750 W unit is hot-swappable; pull the failed module while the other remains live, insert the replacement, and verify the green status LED before closing the rack door.
