Dual-socket Xeon Gold 6142 platform

The PowerEdge R640 is a 1U rack server built around two Intel Xeon Gold 6142 processors. Each CPU delivers 16 cores at 2.6 GHz with a 3.7 GHz turbo frequency. The system targets dense scale-out data centre workloads that demand high core counts in minimal rack space.

Sustained compute and storage throughput

Twenty-four DDR4 slots populated with 256 GB of 2666 MHz registered ECC memory feed the dual processors continuously. The PERC H730P controller with 2 GB cache drives eight 600 GB 10K SAS drives at 12 Gb/s, supporting RAID 0, 1, 5, 6, 10, 50 and 60 for consistent I/O under load. Redundant 750 W platinum power supplies maintain delivery during extended operation.

SAS 12 Gb/s and 10 GbE connectivity limits

The storage bus tops out at 12 Gb/s per lane, capping drive-to-controller bandwidth. Network I/O is handled by an Intel X520/I350 daughter card providing two 1 GbE and two 10 Gb SFP+ ports. The 1U chassis holds a maximum of eight 2.5-inch drives, so total raw capacity is bounded by the installed 600 GB SAS devices.

Questions about this item

How much power do the two Xeon Gold 6142 processors and the 750 W platinum power supplies draw when the R640 runs 24/7?

The server includes two 750 W platinum-efficiency hot-swap power supplies in a redundant configuration, supporting continuous operation.

Which rails and bezel are required to mount this 1U R640 in a standard rack?

Ready Rails and a front bezel are included with the system for direct rack installation.

Can the PERC H730P controller use the existing 600 GB 10K SAS drives together with larger SATA drives in the same array?

The H730P supports SAS and SATA drives with RAID 0, 1, 5, 6, 10, 50, 60 and pass-through, allowing mixed drive types in supported configurations.
