Dual-socket 1U density

The Dell PowerEdge R640 packs two Intel Xeon Gold 6142 processors, each with 16 cores at 2.6 GHz, into a single rack unit. It ships with 768 GB of DDR4 registered ECC memory across all 24 slots. Eight 300 GB 10K SAS drives and a PERC H730P controller provide internal storage. Dual 750 W platinum power supplies and iDRAC9 Enterprise complete the package.

Upgrade from single-socket or smaller memory

Moving from a single-processor server doubles the core count to 32 and raises the memory ceiling to 3 TB. The jump is worth it when workloads such as virtualisation, database or high-performance computing need more parallel threads and larger datasets than a single socket can address. The board already holds the maximum of two processors, so further CPU expansion requires a new chassis.

12 Gb/s SAS controller and 10K spindle limits

The PERC H730P operates at 12 Gb/s over SAS and SATA, capping throughput to the speed of the installed 10 000 RPM drives. Random I/O will be bounded by mechanical latency, and sequential transfers cannot exceed the controller's 12 Gb/s lane rate. The network daughter card adds two 10 Gb SFP+ ports, but the 1 GbE links remain at their fixed line rate.

Questions sur cet article

What rack depth and rail kit are required for the 1U R640?

The server is a 1U rack chassis and ships with Ready Rails for tool-less mounting in a standard four-post rack.

Which BIOS step is often missed when installing the dual Xeon Gold 6142 processors and 24 DDR4 DIMMs?

After seating both CPUs and all 24 memory modules, enter the BIOS to verify the 2.6 GHz clock speed and 2666 MHz memory frequency before configuring RAID.

When should the PERC H730P controller battery and the 300 GB 10K SAS drives be replaced?

Replace the RAID controller battery every 3 to 5 years and monitor the 300 GB SAS drives via iDRAC 9 Enterprise SMART alerts for predictive failure.
