HDD 24 x 300GB 10K SAS

  • Dual Xeon Gold 6142 CPUs provide 32 cores at 2.6 GHz base with 3.7 GHz turbo
  • 256 GB DDR4 2666 MHz registered ECC memory across 8 modules for large workloads
  • PERC H730P 2 GB controller supports RAID 0, 1, 5, 6, 10, 50, 60 and pass-through
  • Twenty-four 300 GB 10 K SAS drives in 2.5 inch bays deliver high-density storage
  • Quad-port X520/I350 card adds two 1 GbE and two 10 Gb SFP+ connections

Storage-dense 2U platform

The Dell PowerEdge R740xd fits twenty-four 2.5-inch drive bays into a two-socket 2U chassis, giving software-defined storage clusters and virtual-desktop farms a high-capacity foundation. Dual Xeon Gold 6142 processors supply sixteen cores each at 2.6 GHz, while 256 GB of DDR4-2666 registered ECC memory feeds memory-hungry workloads.

Thermals and power in steady state

Redundant 1100 W platinum-efficiency supplies share the load, keeping conversion losses low during typical virtualization or storage duties. The 2U airflow path draws cool air across the CPUs, memory risers and the PERC H730P controller, so fan speeds remain moderate and acoustic output stays within data-centre norms.

Behaviour under sustained load

When all thirty-two cores hold 3.7 GHz turbo across extended compute or RAID rebuilds, the dual power supplies maintain headroom without throttling. The H730P’s 2 GB cache absorbs write bursts while the twenty-four 300 GB 10K SAS drives deliver consistent IOPS, and iDRAC 9 Enterprise provides continuous telemetry so operators can act before thermal limits are reached.

Questions about this item

How do I install the 24 2.5-inch SAS drives and what step is often missed?

Slide each drive into the front 2.5-inch bays until the latch clicks; the step often missed is configuring the desired RAID level on the PERC H730P before loading the operating system.

What maintenance or replacement will the PERC H730P battery need later?

The PERC H730P includes a battery-backed cache; the battery should be replaced every three to five years to preserve write-cache protection during power loss.

What limit appears first under sustained heavy I/O on the 24 300 GB 10K SAS drives?

The 10K SAS drives reach their sustained throughput ceiling before the 12 Gb/s SAS backplane or H730P controller saturate, making drive IOPS the first bottleneck.
