Enterprise 2U rack server

The Dell PowerEdge R750 is a 2U rack server built for enterprise workloads that demand high core counts and large memory capacity. It ships with two Intel Xeon Silver 4316 processors, each running at 2.3 GHz with 20 cores and a 3.4 GHz turbo frequency. The system includes 256 GB of DDR4 2666 MHz registered ECC memory across eight 32 GB modules. iDRAC9 Enterprise provides comprehensive remote management capabilities.

Sustained load behaviour

Redundant 1400 W platinum power supplies and hot-swap redundancy keep the platform stable during continuous operation. The PERC H755 controller with 8 GB NV cache and battery backs write performance across RAID 0, 1, 5, 6, 10, 50 and 60 levels. Twenty-four 2.5-inch SAS/SATA drive trays allow storage expansion without downtime. Quad-port 1 GbE OCP 3.0 networking maintains connectivity under heavy traffic.

Deciding specification

The server maxes out at two processors and 32 DDR4 DIMM slots, so total CPU cores and memory capacity are fixed at this configuration. Buyers who need more than 40 cores or memory beyond the installed 256 GB must choose a different platform. The 2.5-inch drive bay count of 24 also sets a hard limit on internal SAS/SATA device density.

Questions about this item

How much power do the dual 1400 Watt supplies draw under sustained load and how loud are the fans?

Two 1400 Watt platinum supplies provide redundant hot-swap power; fan speed scales with CPU and inlet temperature so acoustic output rises with workload.

Which rails and rack standard are needed to mount the 2U chassis?

Ready rails are included for a standard four-post rack; the server occupies 2U of vertical space.

Can the H755 controller use my existing 2.5-inch SAS or SATA drives in the 24 front bays?

The PERC H755 supports RAID 0, 1, 5, 6, 10, 50, 60 on 24 2.5-inch SAS/SATA trays; NVMe drives are not supported by this controller.
