Dense compute platform

The PowerEdge R640 packs two Xeon Platinum 8160 processors into a single rack unit, delivering twenty-four cores per CPU at 2.10 GHz base frequency with 3.7 GHz turbo capability. It ships with 768 GB of DDR4 registered ECC memory across twenty-four slots and eight 400 GB SATA SSDs managed by a PERC H730P controller supporting RAID levels 0, 1, 5, 6, 10, 50 and 60. Dual 750 W platinum power supplies, quad-port networking with two 1 GbE and two 10 Gb SFP+ links, and iDRAC9 Enterprise remote management complete the package.

Scale-out workloads vs specialised needs

This server suits organisations running virtualisation clusters, high-performance databases or containerised microservices that benefit from high core density and fast local storage in minimal rack space. Buyers who need more storage bays, GPU acceleration, or single-thread performance beyond the 3.7 GHz turbo ceiling should evaluate alternative platforms.

Twenty-four cores per socket

Each Xeon Platinum 8160 provides twenty-four cores, so the dual-socket configuration yields forty-eight total cores; this core count is the decisive factor for licensing costs and parallel throughput planning.

Questions about this item

How much power do the two 750 W supplies draw when the server runs at full load all day?

Each supply is rated at 750 W with Platinum efficiency; the system draws only what the components require, up to that limit.

Which cables or modules are needed to use the X520 10 Gb SFP+ ports on the network daughter card?

The card accepts standard SFP+ transceivers and compatible direct-attach or fibre cables for 10 GbE links.

Can the PERC H730P controller manage the existing 400 GB SATA SSDs together with larger SATA drives I already own?

Yes, the H730P supports mixed-capacity SATA SSDs in the same array, using RAID 0, 1, 5, 6, 10, 50 or 60.
