2U rack server with dual 20-core Xeon Gold 6148 CPUs, 768GB DDR4, PERC H730P RAID controller and 24 hot-swap 2.5-inch drive bays
The PowerEdge R740xd is a 2U rack server fitted with two 20-core Intel Xeon Gold 6148 processors at 2.4 GHz. It targets environments that need dense 2.5-inch drive capacity alongside strong multi-threaded compute, such as software-defined storage clusters or virtual desktop infrastructure hosts.
The system ships with 768 GB of DDR4-2666 registered ECC memory across 24 slots, leaving room to grow to the 3 TB maximum. Twenty-four hot-swap 2.5-inch SAS/SATA trays connect to a PERC H730P 2 GB controller supporting RAID 0, 1, 5, 6, 10, 50 and 60, so capacity scales until the bays or the controller throughput are saturated.
Dual hot-swap 1100 watt platinum-efficiency power supplies share the load, keeping fan speeds moderate under typical utilisation. The integrated iDRAC 9 Enterprise controller provides out-of-band monitoring and remote management without adding acoustic overhead, while the quad-port X520/I350 daughter card handles 1 GbE and 10 GbE SFP+ traffic.

Other versions of this model
The PERC H730P 2GB controller supports both SAS and SATA interfaces, and the 24 drive trays are designed for 2.5" SAS/SATA drives, so your existing drives will fit and work.
Check the POST screen and iDRAC9 Enterprise system inventory; both will list the two 20-core processors running at 2.4GHz with 3.7GHz turbo and show all 24 memory modules populated.
The unit ships with 24 Dell 2.5" SAS/SATA drive trays, ready rails, front bezel and two redundant 1100W platinum power supplies — only drives need to be purchased separately.
