Dell PowerEdge R640 dual Xeon server

The Dell PowerEdge R640 is a 1U rack server fitted with two Intel Xeon Silver 4114 processors running at 2.2GHz. Each CPU provides ten cores and 13.75MB of cache, giving twenty cores in total. The system ships with 256GB of DDR4 ECC registered memory installed across the available slots. It is aimed at organisations that need dense compute for virtualisation, database or high-performance workloads in a standard rack footprint.

Four 3.5-inch drive bays with SATA interface

The chassis supports up to four 3.5-inch drives connected through a SATA backplane and the Dell PERC H740P RAID controller. No drives are included, so buyers must supply their own SATA HDDs or SSDs. The controller handles RAID levels supported by the H740P firmware, but the interface limits throughput to SATA speeds. The board provides a maximum memory ceiling of 7.68TB, though only 256GB is populated in this configuration.

Dual 750W supplies and iDRAC9 Enterprise remote

Two 750W power supplies provide redundancy for continuous operation. Remote management is handled by iDRAC9 with an Enterprise licence, allowing out-of-band monitoring, firmware updates and virtual console access over the network. A 10GbE two-port 562T adapter is installed for high-speed connectivity. The unit measures 36 by 24 by 10 inches and weighs 40 units; rail kits are available on request.

商品問答

Should I choose the 4LFF chassis or a different drive-bay layout for the PowerEdge R640?

The 4LFF chassis provides four 3.5-inch bays for high-capacity SATA drives. If you need more bays in the same 1U height you would need the small-form-factor version, which is not this model.

What does the 2.2 GHz figure mean for the two Xeon Silver 4114 CPUs once the server is running workloads?

Each Xeon Silver 4114 runs at a base frequency of 2.2 GHz across its 10 cores, giving 20 cores total. Turbo can raise clocks higher depending on thermal headroom and the number of active cores.

How does the PERC H740P controller and SATA interface limit the storage performance I can get?

The PERC H740P connects to the four 3.5-inch bays through SATA links. Drive throughput will not exceed the SATA bus, so the controller’s cache and RAID features operate within that ceiling.
