Dual-socket 1U server with 768GB DDR4

The Dell PowerEdge R640 is a 1U rack server equipped with two Intel Xeon Silver 4116 processors, each running at 2.1GHz with 12 cores. It provides 768GB of DDR4 registered ECC memory across 24 slots and includes a PERC H730P storage controller with 2GB cache. Eight 1.2TB 10K SAS drives and a quad-port network daughter card with two 1GbE and two 10Gb SFP+ ports complete the configuration.

Suited for dense scale-out workloads

This platform suits buyers who need high core counts and large memory capacity in a single rack unit for virtualisation, database or high-performance computing clusters. Redundant 750W platinum power supplies and iDRAC9 Enterprise management support continuous operation. Buyers who require GPU acceleration or all-flash arrays should look at other configurations. Builders needing more than two processors or memory beyond 3TB will need a different chassis.

Storage decided by eight 1.2TB SAS drives

The installed storage consists of eight 1.2TB 10K SAS hard drives connected to the H730P controller, which supports RAID 0, 1, 5, 6, 10, 50 and 60 plus pass-through. This drive count and interface determine usable capacity, I/O performance and redundancy options. No solid-state drives are included, so buyers who need flash latency must add them separately.

Questions sur cet article

How do I install the 24 DDR4 memory modules in the 1U chassis, and which slot population rule do people overlook?

The R640 has 24 DDR4 slots across two processors; fill all 12 slots per CPU in identical pairs to enable quad-channel operation — skipping a pair cuts bandwidth in half.

When will the PERC H730P controller battery need replacement, and what fails first if it is ignored?

The 2 GB cache battery typically lasts 3 to 5 years; once depleted the controller disables write-back caching, slowing every RAID 5, 6, 50 or 60 write.

Which thermal limit appears first when both Xeon Silver 4116 CPUs run at 3.0 GHz turbo under sustained load?

The 1U form factor caps total CPU power at 285 W; dual 2.1 GHz 12-core chips hit that ceiling before memory or drive temperatures become critical.
