Rack server for virtualisation and databases

The Dell PowerEdge R640 is a 1U rack-mount server built for virtualisation clusters and database workloads. It ships with a single Intel Xeon Bronze 3106 processor running at 1.7GHz and 128GB of DDR4 ECC registered memory. A second processor socket is available for future expansion up to the platform maximum.

Dual 750W supplies and iDRAC9 remote management

Redundant 750W power supplies share the load during normal operation, keeping power draw stable across both units. The iDRAC9 Enterprise licence provides out-of-band monitoring and remote console access without needing the operating system to be running. Integrated graphics handle basic display output for local maintenance tasks.

Four 3.5-inch bays with PERC H740P RAID controller

The chassis supports up to four 3.5-inch SATA drives managed by the PERC H740P hardware RAID controller for array configuration and data protection. A 10GbE dual-port 562T network adapter delivers high-throughput connectivity for storage and migration traffic. Rail kits are available on request for standard rack installation.

Questions about this item

How do I install the PERC H740P RAID controller in the R640 and which step is often missed?

The PERC H740P installs in the dedicated internal storage slot; the step often missed is fully seating the controller so the edge connector engages the motherboard header.

What maintenance or replacement will the R640 need later?

The two 750 W power supplies and the system fans are the only field-replaceable units that wear out; both are hot-swappable and can be replaced without tools.

What limit appears first under sustained load on the Xeon Bronze 3106?

The 1.7 GHz base clock is the first limit; the 8-core Bronze 3106 cannot turbo higher, so prolonged heavy compute hits that frequency ceiling before thermal throttling begins.
