Dense storage compute

The Dell PowerEdge R740xd packs twenty-four 2.5-inch drive bays into a 2U rack chassis with dual Xeon Gold 6148 processors. Each CPU runs twenty cores at 2.4 GHz with a 3.7 GHz turbo, giving forty cores total for virtualisation or software-defined storage workloads.

SAS/SATA controller ceiling

The PERC H730P handles twelve-gigabit SAS and six-gigabit SATA links with RAID levels up to 60 plus pass-through. All twenty-four front bays share this single controller, so aggregate throughput caps at the card's twelve-gigabit SAS pipe rather than per-drive speeds.

768GB memory headroom

Seventy-six-eight gigabytes of DDR4-2666 registered ECC fill all twenty-four DIMM slots, leaving no room for expansion without replacing modules. The platform supports up to three terabytes, so memory-heavy databases or VDI clusters will need higher-capacity DIMMs to grow beyond the current configuration.

Questions about this item

Should I choose the 768GB configuration or add more DDR4 modules up to the 3TB maximum?

The server ships with 768GB across 24 slots using 32GB DDR4 2666MHz registered ECC modules; all slots are populated, so expanding to 3TB requires replacing modules with higher-capacity DDR4 DIMMs.

What does the 2.4GHz base clock with 3.7GHz turbo mean for sustained workloads on the dual Xeon Gold 6148 CPUs?

Each of the two 20-core Xeon Gold 6148 processors runs at 2.4GHz base and can boost to 3.7GHz; sustained all-core performance will sit between those frequencies depending on thermal headroom and the 1100W platinum power supplies.

How does the PERC H730P 12Gb/s SAS/SATA controller limit the installed 400GB SATA SSDs?

The H730P provides 12Gb/s SAS and 6Gb/s SATA connectivity; the two 400GB SATA SSDs operate at SATA 6Gb/s speeds, while the controller supports RAID 0/1/5/6/10/50/60 and pass-through for additional drives.
