Dell PowerEdge R750 2U rack server

The Dell PowerEdge R750 is a 2U rack server built for enterprise workloads. It ships with two Intel Xeon Gold 6338 processors, each running at 2.0 GHz with 32 cores. The system includes 128 GB of DDR4 registered ECC memory across eight 16 GB modules. Twenty-four 1.8 TB SAS hard drives provide high-capacity storage managed by a PERC H755 RAID controller with 8 GB NV cache.

Suits virtualisation and database clusters.

This configuration suits virtualisation hosts, database clusters, and memory-heavy applications needing many cores and large local storage. The 24-bay 2.5-inch chassis and dual 1400 W power supplies support dense deployments. Buyers needing GPU acceleration or NVMe-only storage should consider alternative platforms, as this unit ships with SAS drives and no GPU provisioning.

24-bay 2.5-inch SAS drive capacity decides fit

The single specification that decides fit is the 24-bay 2.5-inch SAS drive capacity paired with the H755 controller supporting RAID 0, 1, 5, 6, 10, 50, and 60. This layout determines whether the server matches your storage density and redundancy requirements. iDRAC 9 Enterprise and dual 10 GbE SFP+ ports complete the management and networking baseline.

Perguntas sobre este artigo

How much power do the dual 1400 Watt PSUs draw when the server runs continuously under load?

The server includes two 1400 Watt platinum-efficiency power supplies with hot-swap redundancy. Actual draw depends on workload, but the platinum rating means high conversion efficiency at typical loads.

Which cabling and SFP+ modules must I supply for the Broadcom 57412 dual-port 10GbE OCP 3.0 card?

The OCP 3.0 card provides two SFP+ ports. You need compatible SFP+ transceivers and either direct-attach copper or fibre patch cables for 10 GbE links.

Will the PERC H755 controller recognise my existing 12 Gb/s SAS drives if I move them into the 24-bay 2.5 inch chassis?

Yes. The H755 supports 12 Gb/s SAS and the backplane accepts 2.5 inch SAS drives, so your current 12 Gb/s SAS disks will be detected and can be imported into new virtual disks.
