Dell PowerEdge R940 four-socket rack server

This Dell PowerEdge R940 is a 3U rack server built around four Intel Xeon Gold 5120 processors running at 2.2 GHz with 14 cores each. It ships with 256 GB of DDR4 registered ECC memory across 48 slots and eight 1.2 TB 10K SAS drives managed by a PERC H730P controller. Dual 1600 W platinum power supplies and iDRAC 9 Enterprise provide redundancy and remote management.

Suited for high-core-count database

The four-socket design delivers 56 total cores and supports up to 6 TB of DDR4, making it appropriate for memory-intensive applications that scale across many threads. Organisations that require only a single or dual-socket platform, or that need a smaller chassis than 3U, will not match this form factor.

Storage controller and drive interface set

The PERC H730P 2 GB controller handles SAS and SATA drives with RAID levels 0, 1, 5, 6, 10, 50 and 60 plus pass-through. All eight 2.5-inch bays are populated with 1.2 TB SAS drives, so any further storage changes must use the same SAS interface and controller capabilities.

Questions about this item

What is the correct order for inserting the eight 1.2TB SAS drives into the 2.5-inch bays?

Each drive carrier slides into a numbered bay until the latch clicks; the PERC H730P controller auto-detects the SAS links at 12Gb/s so no manual mapping is required.

When should the PERC H730P 2GB cache battery be replaced?

The battery backs the 2GB write cache; plan replacement after three to five years or if iDRAC9 Enterprise reports a degraded battery status.

Which thermal limit triggers first when all four Xeon Gold 5120 CPUs run at 3.2GHz Turbo continuously?

The 1600 Watt platinum power supplies and redundant hot-swap fans manage heat; the first throttle point is the CPU package thermal ceiling enforced by the C620 chipset.
