DELL PowerEdge R640 4LFF 1x Xeon Gold 6154 128GB DDR4 No Drive rack server

Dell PowerEdge R640 4LFF single-processor server

The Dell PowerEdge R640 is a 1U rack-mount server equipped with one Intel Xeon Gold 6154 processor running at 3 GHz with 18 cores and 128 GB of DDR4 ECC registered memory. It includes a Dell PERC H740P RAID controller and an Ethernet 10 GB 2-port 562T adapter for high-speed networking. The chassis supports up to four 3.5-inch drive bays, though no drives are installed in this configuration. It is designed for organisations needing a dense, single-socket platform with enterprise remote management via iDRAC9 Enterprise license.

Suited for memory-intensive single-socket workloads

This server fits virtualisation hosts, database nodes and compute clusters that benefit from 128 GB of DDR4 ECC memory and an 18-core Xeon Gold 6154 CPU while leaving a second processor socket free for future expansion. It is not for buyers who require dual-processor performance immediately or who need internal storage pre-installed. Organisations needing GPU acceleration or more than four 3.5-inch drive bays should evaluate other platforms.

Four 3.5-inch drive bays with PERC H740P controller

The backplane provides four 3.5-inch SATA bays connected to a Dell PERC H740P RAID controller, which determines the RAID levels and drive types you can deploy. No drives ship with the unit, so you must supply compatible SATA hard drives or SSDs to match your capacity and redundancy requirements. This bay count and controller combination is the deciding factor for storage density and data-protection options.
