Dual-socket 1U rack server

The PowerEdge R640 packs two Xeon Gold 5118 processors into a single rack unit. Each CPU delivers 12 cores at 2.3 GHz with a 3.2 GHz turbo frequency. The system ships with 64 GB of DDR4 registered ECC memory across four 16 GB modules. It targets organisations that need high compute density in a compact footprint.

12 Gb/s SAS controller limits

The PERC H730P controller operates at 12 Gb/s over SAS and SATA links. It supports RAID levels 0, 1, 5, 6, 10, 50 and 60 plus pass-through mode. Eight 2.5-inch drive bays are wired to this controller. Throughput is bounded by the 12 Gb/s interface and the 10 000 rpm mechanical drives installed.

24 DDR4 slots with 3 TB ceiling

The platform provides 24 DIMM slots and a maximum memory capacity of 3 TB. Only DDR4 registered ECC modules are compatible. Buyers planning larger memory footprints must populate the remaining 20 slots with matching DDR4 parts. Builders who need a different memory generation cannot use this server.

Questions about this item

Which drive configuration should I pick for the eight-bay 2.5" chassis?

The unit ships with eight 300 GB 10 K SAS drives on a H730P controller supporting RAID 0/1/5/6/10/50/60 and pass-through; choose this setup when you need 12 Gb/s SAS throughput and enterprise-grade spindle speed.

What does the 2.3 GHz base clock mean once the Xeon Gold 5118 CPUs are under load?

Each 12-core processor can turbo up to 3.2 GHz, so the 2.3 GHz base is the guaranteed minimum frequency across all cores; actual speeds depend on workload, thermals and power limits.

What does the 12 Gb/s SAS interface cap in practice with the PERC H730P?

The controller and backplane run at 12 Gb/s per lane, so each installed 300 GB 10 K drive can saturate that link; total array bandwidth scales with the RAID level and number of active spindles.
