Dense 1U compute platform

The PowerEdge R640 packs two Xeon Gold 6142 processors, each with 16 cores at 2.6 GHz, into a single rack unit. It ships with 128 GB of DDR4 registered ECC memory across eight slots. The PERC H730P controller manages eight 300 GB SAS drives. Quad-port networking adds two 1 GbE and two 10 Gb SFP+ links. iDRAC 9 Enterprise handles remote management. Dual 750 W platinum supplies provide redundant power.

Installation notes

The server arrives with rails and a front bezel fitted, so rack mounting is straightforward. Hot-swap drive bays and redundant power supplies allow component changes without downtime. The 24 DIMM slots are partially populated, leaving room for memory expansion up to 3 TB. Cable routing in a 1U chassis is tight; plan cable runs before sliding the unit into place. The PERC H730P battery-backed cache must be seated correctly for RAID protection to activate.

Sustained load behaviour

Dual 16-core CPUs maintain 2.6 GHz base frequency under continuous multi-threaded workloads, with turbo up to 3.7 GHz when thermal headroom allows. Platinum-efficiency power supplies deliver stable output during prolonged peaks. The H730P controller sustains RAID 0, 1, 5, 6, 10, 50 and 60 throughput across the eight 10 K SAS spindles. iDRAC 9 Enterprise monitors thermals and power in real time, enabling proactive throttling before overheating occurs. Redundant fans keep airflow steady even if one module fails.

Questions about this item

How do I verify the two Xeon Gold 6142 processors are recognised after powering on the R640?

Open the iDRAC 9 Enterprise web interface or press F2 during POST; the System Overview screen will show both 16-core CPUs running at 2.6 GHz with 3.7 GHz turbo enabled.

Which components are included and what must I source separately for the R640?

The unit ships with 2× Xeon Gold 6142 CPUs, 128 GB DDR4 ECC memory, PERC H730P controller, 8× 300 GB 10K SAS drives, X520/I350 quad-port NIC, iDRAC 9 Enterprise, dual 750 W PSUs, rails and bezel; only OS licences and any extra drives or memory are separate.

Which memory capacity should I choose if I want to expand the R640 later?

The board has 24 DDR4 slots and supports up to 3 TB; with 8× 16 GB modules installed you still have 16 free slots for future Registered ECC DDR4 2666 MHz upgrades.
