Dual-socket 2U rack server for virtualization

The Dell PowerEdge R750 packs two Intel Xeon Gold 6330 processors at 2.0 GHz with 28 cores each, 256 GB of DDR4-2933 registered ECC memory, and a PERC H755 RAID controller with 8 GB NV cache. Twenty-four 1.92 TB SATA SSDs provide high-density flash storage in a 2U chassis with dual 1400 W platinum power supplies, iDRAC9 Enterprise management, quad-port 1 GbE networking, rails and bezel.

Ideal for consolidation and storage-heavy workloads

This configuration suits teams running virtualised databases, analytics or VDI clusters that need abundant core count and all-flash capacity in a standard rack slot. Organisations requiring NVMe throughput, GPU acceleration, or more than two sockets should evaluate alternative platforms. Buyers needing 3.5-inch drive bays or single-socket economy will not match this form factor.

24-bay 2.5-inch SATA backplane with PERC H755 RAID

The front panel accepts exactly twenty-four 2.5-inch SATA drives managed by the H755 controller supporting RAID 0, 1, 5, 6, 10, 50 and 60. This drive-count and controller combination determines raw capacity, rebuild times and the RAID levels available for data protection.

Questions about this item

How often should the H755 RAID controller battery be checked or replaced?

The PERC H755 includes an 8 GB NV cache backed by a battery; Dell recommends checking battery status via iDRAC9 Enterprise annually and replacing the battery module when the controller reports degraded capacity, typically every 3 to 5 years under continuous operation.

Which component reaches its thermal or power ceiling first during sustained 24/7 workloads?

The two 1400 W platinum power supplies and dual Xeon Gold 6330 CPUs (2.0 GHz base, 3.1 GHz turbo) set the sustained power envelope; under full load the CPUs and 24 SATA SSDs will hit the thermal design limits before memory or the H755 controller.

What is the typical noise and heat output when the server runs all day in a 2U rack?

With dual 1400 W platinum PSUs and 24 SATA SSDs, the R750 produces significant airflow noise — expect data-centre grade fan levels — and exhaust heat approaching the combined CPU and drive thermal design power, requiring proper rack cooling and aisle containment.
