Dual-socket 1U rack server

The PowerEdge R640 is a 1U rack server equipped with two Intel Xeon Gold 6142 processors running at 2.6 GHz with 16 cores each. It provides 768 GB of DDR4 registered ECC memory across 24 slots and includes a Dell PERC H730P 2 GB storage controller with battery-backed cache. Two 800 GB SATA SSDs are installed in the 2.5-inch drive bays, and a quad-port network daughter card adds two 1 GbE and two 10 Gb SFP+ connections. iDRAC9 Enterprise and redundant 750 W platinum power supplies complete the platform.

Suited for dense virtualization.

This configuration suits organisations running dense virtualization, high-performance computing or database workloads that benefit from 32 total cores and a large memory footprint. The 24 DIMM slots allow expansion up to the platform maximum of 3 TB. Buyers who need more than eight 2.5-inch drive bays or who require a different drive interface should consider alternative chassis designs. The fixed 1U height limits PCIe expansion to low-profile cards only.

768 GB DDR4 registered ECC memory installed

The system ships with 768 GB of DDR4 2666 MHz registered ECC memory populated across all 24 slots. This capacity determines how many virtual machines or in-memory datasets can run simultaneously without swapping. Memory type and speed are fixed to DDR4 registered ECC; other generations or unbuffered modules are not compatible. Verifying the application memory requirement against this installed total is the primary step in confirming suitability.

Questions sur cet article

Does the 1U R640 chassis include the ready rails needed for a standard four-post rack?

Yes, the ready rails and front bezel are included with the server so it can be mounted directly into a standard four-post rack.

What is the correct order for seating the two Xeon Gold 6142 processors and the 24 DDR4 DIMMs during initial build?

Install both processors into the LGA 3647 sockets first, then populate the 24 DDR4 slots with the 32 GB registered ECC modules following the memory population guide for the C620 chipset.

Which component of the PERC H730P controller requires periodic replacement to preserve RAID cache protection?

The 2 GB battery-backed cache module on the PERC H730P controller should be monitored and replaced when the iDRAC 9 Enterprise reports a degraded battery status.
