Storage-dense 2U platform

The PowerEdge R740xd fits 24 2.5-inch bays into a 2U rack chassis, giving software-defined storage clusters and virtual desktop infrastructure a high-capacity footprint. Two Xeon Gold 6148 processors and 512 GB of DDR4 ECC memory provide the compute headroom for heavy multi-tenant workloads.

Sustained throughput with hardware RAID

The PERC H730P controller maintains consistent I/O under prolonged write pressure by using its 2 GB cache and battery backup to absorb bursts without throttling. Dual 1100 W platinum power supplies share load evenly, preventing thermal derating during continuous operation.

SATA SSD ceiling and 12 Gb/s controller limit

Installed 400 GB SATA SSDs saturate at the 6 Gb/s link speed, so sequential throughput tops out well below the H730P’s 12 Gb/s SAS ceiling. The 24 DIMM slots and C620 chipset cap memory expansion at 3 TB, defining the practical ceiling for in-memory datasets.

Questions about this item

How loud and hot does the R740xd get when both Xeon Gold 6148 CPUs run at 3.7GHz turbo all day with dual 1100W platinum PSUs?

Dual 1100W platinum supplies and redundant hot-swap cooling handle sustained 3.7GHz turbo loads; fan speed ramps with inlet temperature so noise rises under full CPU utilisation.

What drives and caddies do I need to fill the empty 2.5" SATA bays beyond the two 400GB SSDs?

The chassis accepts 2.5" SATA or SAS drives; Dell 2.5" hot-swap caddies are required for each additional bay.

Will my existing DDR4 2666MHz registered ECC modules work alongside the 16 installed 32GB sticks?

Yes — 24 DDR4 slots support up to 3TB total; matching 2666MHz registered ECC modules can be added to empty slots.
