Dense 1U dual-socket server

The Dell PowerEdge R640 packs two Intel Xeon Gold 6134 3.2GHz 8-core processors and 128GB of DDR4 registered ECC memory into a 1U rack chassis. Eight 2.5-inch drive bays connect to a PERC H730P 2GB controller supporting RAID 0, 1, 5, 6, 10, 50 and 60. Dual 750W platinum power supplies and iDRAC9 Enterprise provide redundancy and remote management. A quad-port network daughter card delivers two 1GbE and two 10Gb SFP+ links.

Suits dense compute clusters.

This configuration targets scale-out workloads such as virtualization, HPC nodes and database tiers that benefit from high core count and fast memory in minimal rack space. The 300GB 10K SAS drives offer low latency for boot or caching but limited capacity. Organisations needing GPU acceleration, more than eight drive bays in 1U, or fibre-channel connectivity should evaluate other platforms.

128GB DDR4 registered ECC across 24 slots

The system ships with eight 16GB DDR4 2666MHz modules populating a third of the available memory slots, leaving room to scale toward the 3TB maximum. Buyers whose applications demand larger memory footprints per node can expand within the same chassis, while those satisfied with the factory capacity can deploy immediately.

Questions about this item

What does the 12Gb/s SAS controller cap in real throughput?

The Dell PERC H730P 2GB controller runs at 12Gb/s SAS/SATA and supports RAID 0, 1, 5, 6, 10, 50, 60 plus pass-through.

What clearance and rails does the 1U chassis require?

The 1U rackmount chassis includes Dell Ready Rails and a front bezel for standard rack installation.

How are the CPUs and memory installed, and what step is often missed?

Two Xeon Gold 6134 processors come pre-installed in LGA 3647 sockets; 128GB DDR4 2666MHz ECC memory populates 8 of 24 slots in matched pairs per processor.
