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.
15G PERC Controller offerings will be a heavy leverage of 14G PERC family. The Value and Value Performance levels will carry over to 15G from 14G. New to 15G, is the Harpoon-based Premium Performance tier offering. This high-end offering will drive IOPs performance and enhanced SSD performance.
