Dense 2U storage server

The Dell PowerEdge R740xd packs 24 drive bays into a 2U rack chassis, making it a compact platform for storage-heavy workloads. Dual Xeon Gold 6148 processors and 512 GB of DDR4 memory provide the compute headroom for virtualisation or software-defined storage clusters.

SATA throughput ceiling

The installed H730P controller and backplane operate over 12 Gbit/s SAS lanes, yet every fitted drive uses the SATA 6 Gbit/s interface. Sequential throughput will therefore top out at the SATA link speed rather than the controller’s maximum, limiting peak bandwidth for the current SSD set.

24-bay 2.5" chassis constraint

Only 2.5-inch drives fit the front bays, so 3.5-inch HDDs cannot be used without a separate enclosure. Buyers who need larger-capacity 3.5-inch spindles must look elsewhere.

Perguntas sobre este artigo

Should I choose the 20-core Xeon Gold 6148 or a lower-core option?

The server ships with two Xeon Gold 6148 processors, each 20 cores at 2.4 GHz with 3.7 GHz turbo, filling both sockets; no lower-core variant is included.

What does 512 GB DDR4 mean for actual workloads?

512 GB is installed as sixteen 32 GB DDR4 2666 MHz registered ECC modules across 24 slots, leaving eight slots free for expansion up to 3 TB.

How does the H730P controller limit drive performance?

The PERC H730P provides 12 Gb/s SAS/SATA connectivity with 2 GB cache and battery backup, supporting RAID 0, 1, 5, 6, 10, 50, 60 and pass-through for the 2.5" bays.
