PowerEdge R750 12-Bay 3.5" Server

The Dell PowerEdge R750 is a 2U rack server equipped with two Intel Xeon Gold 5317 processors running at 3.0 GHz with a 3.6 GHz turbo frequency. It includes 1 TB of DDR4 2933 MHz registered ECC memory across 32 DIMM slots and a PERC H755 RAID controller with 8 GB NV cache. Twelve 3.5-inch 4 TB 7.2K SATA hard drives are installed, and dual 1400 W platinum power supplies provide redundant hot-swap power.

Virtualisation hosts needing dense 3.5-inch capacity

This configuration suits teams that want a single 2U chassis with twelve large SATA drives and dual 12-core Xeons for memory-heavy workloads. Buyers who require NVMe speeds, 2.5-inch drive bays, or more than two processor sockets should look at a different platform. The system arrives new with iDRAC9 Enterprise, a Broadcom 57412 dual-port 10 GbE SFP+ OCP card, rails and a front bezel.

PERC H755 RAID controller with 8 GB NV cache

The installed H755 supports RAID 0, 1, 5, 6, 10, 50 and 60 and backs its cache with a battery. This single component determines whether the drive array can deliver the redundancy and write performance your workload expects.

Questions about this item

How are the 3.5" drives installed in the 12-bay front chassis, and which step is commonly missed?

Slide each drive into a bay until the carrier latch clicks; the step often missed is pressing the latch fully so the drive seats on the backplane connector.

What maintenance will the PERC H755 RAID controller's 8GB NV cache battery require?

The cache battery is a replaceable module; plan to swap it every three to five years or when iDRAC 9 Enterprise reports a degraded state.

Which limit appears first when all twelve 7.2K SATA drives sustain heavy write workloads?

The 6 Gb/s SATA link on each drive saturates before the controller or PCIe bus, capping sustained throughput per drive.
