5 Memory subsystem The PowerEdge R750xs supports up to 16 DIMMs, with up to 1024 GB of memory and speeds of up to 3200MT/s. The PowerEdge R750xs supports registered (RDIMMs) that use a buffer to reduce memory loading and provide greater density, allowing for the maximum platform memory capacity. Topics: • • Supported memory Memory speed Supported memory The table below lists the memory technologies supported by the platform. Table 4.

DIMM performance details (continued) DIMM type Rank 2R Capacity DIMM rated voltage and speed Operating speed for DIMMs per Channel (DPC) 16 GB, 32 GB, 64 GB DDR4 (1.2V), 3200 MT/s 3200 MT/s NOTE: Maximum memory speed supported on the system depends on the processor specifications. So, while the DIMMs supports up to 3200 MT/s, the processor may not support this memory speed. Please refer table Supported processors.
6 Storage Topics: • • Storage controllers Internal storage configuration Storage controllers 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 Performance levels will carry over to 15G from 14G.
7 Networking Topics: • • Overview OCP 3.0 support Overview PowerEdge offers a wide variety of options to get information moving to and from our servers. Industry best technologies are chosen, and systems management features are added by our partners to firmware to tie in with iDRAC. These adapters are rigorously validated for worry-free, fully supported use in our servers.

8 Expansion cards and expansion card risers NOTE: A system event entry is logged in the iDRAC Lifecycle Controller if an expansion card riser is not supported or missing. It does not prevent your system from turning on. However, if a F1/F2 pause occurs with an error message, see Troubleshooting expansion cards section in the Dell EMC PowerEdge Servers Troubleshooting Guide at www.dell.com/ poweredgemanuals.

The following table provides guidelines for installing expansion cards to ensure proper cooling and mechanical fit. The expansion cards with the highest priority should be installed first using the slot priority indicated. All the other expansion cards should be installed in the card priority and slot priority order. Table 12.

10 Rack, rails, and cable management Key factors in selecting the proper rails include, Identifying: ● Type of rack in which the rails will be installed ● Spacing between the front and rear mounting flanges of the rack ● Type and location of any equipment mounted on the rear of the rack such as power distribution units (PDUs), and the overall depth of the rack Reference the DellEMC Enterprise Systems Rail Sizing and Rack Compatibility Matrix for the following information: ● Specific details about rail types
Figure 22. Sliding rails with optional CMA Figure 23. Sliding rails with optional SRB B22 Stab-in/Drop-in sliding rails for 4-post racks ● Supports Drop-in or Stab-in installation of the chassis to the rails ● Supports tool-less installation in 19-inch EIA-310-E compliant square, unthreaded round hole racks including all generations of Dell racks.
Static rails The static rails, shown in the figure below, support a wider variety of racks than the sliding rails, but do not support serviceability in the rack. The static rails are not compatible with the CMA and SRB.
Strain Relief Bar The optional Strain Relief Bar (SRB) for the system organizes and secures cables exiting the back of the server.
11 Supported Operating Systems The PowerEdge R750xs system supports the following operating systems: ● Canonical® Ubuntu® Server LTS ● Citrix® Hypervisor® ● Microsoft® Windows Server® with Hyper-V ● Red Hat® Enterprise Linux ● SUSE® Linux Enterprise server ● VMware® ESXi® Links to specific OS versions and editions, certification matrices, Hardware Compatibility Lists (HCL) portal, and Hypervisor support are available at Dell EMC Enterprise Operating Systems.
