Memory

The R750xa supports up to 32 DIMMs, with maximum capacity around 10TB per system for 8x 512GB Intel Optane Persistent Memory 200 Series and 8x 128GB LRDIMM connected to per CPU and speeds of up to 3200MT/s.

The R750xa supports registered (RDIMMs) and load reduced DIMMs (LRDIMMs) which use a buffer to reduce memory loading and provide greater density, allowing for the maximum platform memory capacity. Unbuffered DIMMs (UDIMMs) are not supported

DIMM type	DIMM rank	DIMM capacity	DIMM Rated Voltage, Speed
RDIMM	1R	8GB	DDR4 (1.2V), 3200
RDIMM	2R	16GB, 32GB, 64GB	DDR4 (1.2V), 3200
LRDIMM	4R	128 GB	DDR4 (1.2V), 3200

Storage Configuration/Controller Options

The Dell™ PowerEdge™ R750xa is Dell's latest 2-socket, 2U rack servers purposely designed to run all GPU accelerated workloads by supporting the entire PCIe GPUs in Dell™ PowerEdge™ portfolio and using highly scalable memory, I/O, and network options. The systems feature the Intel Xeon Scalable Processor, support to up to 4 double-wide and 8 single-wide GPUs, up to 32 DIMMs, PCI Express® (PCIe) 4.0 enabled expansion slots, and a choice of network interface technologies to cover NIC.

There are only 4 storage configurations in the R750xa, which comprise two backplane options (config 0, config1):

Up to 8x SAS/SATA SSD in a RAID config
Up to 8x NVMe in a RAID config
Up to 6x NVMe direct attach
Up to 4x SAS/SATA SSD in a RAID config Up to 4x NVMe direct attach

Dell's RAID controller options offer performance improvements, including the fPERC solution. fPERC provides a base RAID HW controller without consuming a PCIe slot by using a small form factor and high-density connector to the base planar.
