The Dell PowerEdge R940 fits four Intel Xeon Gold 6134 processors, each with eight cores at 3.2 GHz and a 3.7 GHz turbo frequency. A total of 768 GB of DDR4 2666 MHz registered ECC memory is installed across 24 modules, leaving room for further expansion. The system targets organisations that need dense compute capacity in a standard rack footprint.
Two 1600 watt platinum-efficiency power supplies operate in redundant mode and can be replaced without shutting down. The 3U chassis uses forced-air cooling across the processor and memory zones; fan speeds scale with thermal load to keep components within specification. Power draw varies with CPU utilisation and the eight installed solid-state drives.
Eight 800 GB SATA SSDs occupy the front hot-swap bays, managed by a PERC H730P controller with 2 GB cache and battery backup supporting RAID levels 0, 1, 5, 6, 10, 50 and 60. A daughter card adds two 1 GbE ports and two 10 Gb SFP+ ports for flexible network connectivity. iDRAC 9 Enterprise provides dedicated remote management. Rails and a front bezel are included for rack installation.

Slide each 800GB SATA SSD into a front hot-swap bay until the carrier clicks; the step often missed is pressing the release latch fully so the drive seats on the backplane connector.
The controller uses a 2GB cache backed by a battery; the battery should be checked periodically and replaced when it no longer holds charge to keep write-back caching active.
The dual 1600 Watt platinum power supplies set the ceiling; sustained all-core turbo at 3.7GHz can draw enough power that the PSUs become the limiting factor before thermal throttling occurs.
