PowerEdge R750 12-bay 3.5" 2U server

This 2U rack system ships with dual Xeon Gold 5317 processors, each running at 3.0 GHz with 12 cores and 3.6 GHz turbo. Memory is 256 GB of DDR4-2933 ECC registered DIMMs. A PERC H755 controller with 8 GB NV cache manages twelve 8 TB SAS hard drives. Dual 1400 W platinum power supplies, iDRAC9 Enterprise, a dual-port 10 GbE SFP+ OCP card, rails and bezel are included.

Suited for dense storage and virtualisation.

The twelve 3.5-inch bays and SAS interface make this server a fit for workloads that prioritise raw capacity — backup targets, archival storage or database nodes. The dual-socket design and 256 GB DDR4 also serve virtualisation clusters well. Buyers who need GPU acceleration, NVMe-only arrays or a smaller 1U footprint should look elsewhere.

PERC H755 RAID controller with 8 GB NV cache

The H755 supports RAID 0, 1, 5, 6, 10, 50 and 60 and provides battery-backed write cache. This single component determines both data-protection options and sustained write performance for the twelve installed drives. Confirm the RAID levels and cache size match the application before ordering.

Perguntas sobre este artigo

How do the twelve 3.5-inch 8 TB SAS drives compare to a smaller-bay alternative for capacity planning?

The 12-bay 3.5-inch chassis holds twelve 8 TB SAS hard drives, giving a large raw pool for archival or backup workloads; the 2U form factor fits standard racks while keeping drive count high.

What does the 3.0 GHz base clock with 3.6 GHz turbo mean for sustained workloads on the two Xeon Gold 5317 CPUs?

Each Gold 5317 runs at 3.0 GHz base and can boost to 3.6 GHz under load; with twenty-four total cores the server handles parallel database or virtualization tasks without thermal throttling in a 2U chassis.

How does the PERC H755 controller's 12 Gb/s SAS link affect RAID 5 or 6 rebuild times?

The H755 connects each 7.2K SAS drive at 12 Gb/s and provides 8 GB NV cache with battery backup, so parity rebuilds stream at near wire speed while protecting cached writes during power loss.
