Dell PowerEdge R750xs 2U Rack Server
The Dell PowerEdge R750xs is a 15th Generation cost-optimized 2U rack server positioned between the entry-level R550 and the full-featured R750. It supports 3rd Gen Intel Xeon Scalable processors with up to 32 cores per socket, 16 DDR4 DIMM slots with up to 1 TB of memory, and flexible storage options including up to 16x 2.5-inch + 8x NVMe mixed configurations or 12x 3.5-inch bays.
Enterasource offers the R750xs in multiple chassis configurations. Each server is built to order, tested through our multi-point hardware diagnostic process, and backed by a 2-year Enterasource warranty.
The R750xs includes iDRAC9, PERC H345/H745/H755 RAID controllers, hot-plug BOSS-S2 M.2 boot, and up to 6 hot-swap fans. For workloads that need more storage flexibility than the R550 but do not require the R750's 32 DIMM slots, Optane PMem, or SNAP I/O, the R750xs is the mid-tier 15G 2U option.
