Dual-socket 2U server for enterprise workloads

The Dell PowerEdge R750 is a 2U rack server equipped with two Intel Xeon Silver 4314 processors, each running at 2.4 GHz with 16 cores. It includes 64 GB of DDR4 2666 MHz registered ECC memory across four modules. The system targets virtualization, database, and analytics tasks that demand high core counts and memory reliability. Redundant 1400 W platinum power supplies and sliding rails are included.

Storage and networking limits within the 12-bay

Twelve 3.5-inch drive trays accept SATA or SAS hard drives and SSDs; the PERC H755 controller with 8 GB NV cache supports RAID 0, 1, 5, 6, 10, 50, and 60. A Broadcom 57412 dual-port 10 GbE SFP+ OCP 3.0 adapter provides network connectivity. PCIe Gen4 slots are available for additional expansion cards, though the installed controller and network card occupy two positions. Maximum memory capacity reaches 2 TB across 32 DIMM slots.

Replaces single-socket

Organizations moving from a single-processor 2U platform or an earlier 14G PowerEdge gain a second CPU socket, doubling core count to 32 and enabling the full 2 TB memory ceiling. The jump is worthwhile when workloads exceed the thread or memory limits of a single Silver 4314, or when RAID 50/60 and 10 GbE SFP+ are required out of the box. Buyers needing 2.5-inch NVMe density or GPU compute should evaluate other configurations.

Questions about this item

Should I choose the 12-bay 3.5-inch version or a 2.5-inch model for maximum capacity?

This unit has 12 trays for 3.5-inch SAS/SATA drives, giving the highest raw capacity per bay in the R750 line.

What does the 3.4 GHz turbo figure mean once the server is running a real workload?

The two Xeon Silver 4314 processors can boost from 2.4 GHz to 3.4 GHz on active cores, raising single-thread speed when thermal headroom allows.

Does the OCP 3.0 slot limit the 10 GbE card to a lower speed in practice?

The Broadcom 57412 dual-port 10 GbE SFP+ card runs at line rate on the OCP 3.0 interface, so the slot does not cap throughput.
