Dual Xeon Silver 4314 2U server

The Dell PowerEdge R750 is a 2U rack server built for enterprise workloads that demand strong multi-threaded compute and large memory capacity. Two Intel Xeon Silver 4314 processors provide 32 total cores at 2.4 GHz base with 3.4 GHz turbo. 512 GB of DDR4 2666 MHz registered ECC memory fills 16 DIMM slots. A PERC H755 controller with 8 GB NV cache manages RAID 0, 1, 5, 6, 10, 50 and 60 across twelve 3.5-inch drive bays.

Who should consider this system

Organisations running virtualisation clusters, database instances or analytics jobs that benefit from high core counts and half a terabyte of ECC memory will find the configuration well matched. Buyers who need GPU acceleration, NVMe-only storage or a smaller 1U footprint should evaluate other platforms. The 2U height and dual 1400 W power supplies also require a compatible rack and PDU capacity.

PERC H755 RAID with 8 GB cache

The installed PERC H755 controller is the single component that defines storage capability for this server. Its 8 GB non-volatile cache and battery enable write-back acceleration for RAID 0, 1, 5, 6, 10, 50 and 60 across SAS and SATA drives. Confirm that your drive type and RAID level are supported by this controller before purchase.

Questions about this item

What comes in the box with the PowerEdge R750 and what must I purchase separately?

The server ships with two Xeon Silver 4314 processors, 512 GB DDR4 memory, a PERC H755 RAID controller with 8 GB cache, twelve 3.5-inch drive trays, a quad-port 1 GbE OCP 3.0 card, iDRAC9 Enterprise, two 1400 W platinum power supplies, rails and a front bezel. Drives and any additional memory or PCIe cards are not included.

Which memory capacity should I choose for the R750 — 512 GB or the 2 TB maximum?

The unit already contains 512 GB across sixteen 32 GB DDR4 2666 MHz registered ECC modules. If your workloads fit within that amount, no upgrade is needed; only expand toward the 2 TB limit when applications demand more capacity.

What does the 2.4 GHz base clock mean once the R750 is running real workloads?

Each Xeon Silver 4314 runs at 2.4 GHz base and can boost to 3.4 GHz under load, giving sixteen cores per processor sustained performance for databases, virtualization and analytics while Turbo provides extra headroom for bursty tasks.
