Storage-dense 2U server

The Dell PowerEdge R740xd is a 2U rack server built for workloads that need large drive counts in a compact chassis. It ships with two Intel Xeon Gold 6148 processors, each running at 2.4 GHz with 20 cores, and 64 GB of DDR4 2666 MHz registered ECC memory across four modules.

Suited for storage-first deployments

This configuration fits software-defined storage clusters, virtual desktop infrastructure hosts and service-provider platforms that prioritise internal capacity over GPU or accelerator slots. Buyers who need PCIe expansion for graphics cards, FPGAs or additional high-speed NICs should look at a different chassis.

24-bay 2.5-inch drive capacity

The defining specification is the 24-bay 2.5-inch front backplane that supports SATA and SAS media through the PERC H730P controller with 2 GB cache. This bay count determines whether the server can hold the required dataset without external enclosures.

Perguntas sobre este artigo

Should I pick the 24-bay 2.5" chassis or a smaller bay count?

The 24-bay 2.5" chassis is the only configuration offered for this R740xd, giving you the maximum drive density in a 2U rack form factor.

What does the 3.7GHz turbo figure mean once the server is running workloads?

Each Xeon Gold 6148 can lift from its 2.4GHz base to 3.7GHz turbo when thermal headroom allows, so bursty single-thread tasks see higher clock speeds while sustained loads sit at the base frequency across all 20 cores.

What does the PERC H730P 12Gb/s SAS/SATA controller cap in practice?

The H730P presents a 12Gb/s SAS/SATA interface to the backplane and supports RAID 0, 1, 5, 6, 10, 50, 60 plus pass-through, so drive throughput is limited by the attached SATA SSDs and the 12Gb/s link rather than the controller itself.
