DELL PowerEdge R540 2U rack server 2× Xeon 5118 2.3GHz 12-core 256GB DDR4 8× 4TB SAS H330 iDRAC9 2× 750W

Dual Xeon 12-core 2U server

The Dell PowerEdge R540 is a 2U rack server equipped with two Intel Xeon Gold 5118 processors, each running at 2.3 GHz with 12 cores and a 3.2 GHz turbo frequency. It ships with 256 GB of DDR4 2666 MHz registered ECC memory across eight 32 GB modules. Eight 3.5-inch 4 TB 7.2K SAS drives connect through a PERC H330 12 Gb/s controller, and dual 750 W platinum power supplies provide redundancy.

Upgrade from single-socket or smaller arrays

Replacing a single-processor tower or a 1U server with limited drive bays adds a second 12-core CPU and doubles the memory ceiling to 384 GB across 16 slots. The jump is worth it when workloads outgrow a single socket or when internal storage must exceed four drives without external enclosures.

256 GB memory and 32 TB raw storage headroom

The current 256 GB handles moderate virtualization clusters and database instances comfortably, with room to reach 384 GB for larger page caches. Eight 4 TB SAS drives deliver 32 TB raw capacity for file services or backup targets; the H330 controller caps RAID performance at 12 Gb/s, so all-flash arrays or heavy random I/O will saturate the bus.
