Dense 1U dual-socket server

The PowerEdge R640 packs two Xeon Silver 4110 processors, 768GB DDR4 ECC memory and eight 1.2TB SAS drives into a single rack unit. It targets scale-out workloads that demand high core density and large memory capacity in minimal space. Redundant 750W platinum power supplies and iDRAC9 Enterprise management complete the package.

Steps up from single-socket

Adding the second Silver 4110 doubles thread count and unlocks the full 24 DIMM population for 768GB. The jump is worth it when virtualization, database or HPC clusters hit CPU or RAM ceilings on a single-socket box. The PERC H730P controller supports RAID 0/1/5/6/10/50/60 for flexible data protection.

Limited by 12Gb/s SAS backplane and 1U thermals

The 2.5-inch drive bays connect through a 12Gb/s SAS interface, capping sequential throughput per drive. Ten-thousand RPM disks deliver consistent IOPS but cannot match solid-state latency. The 1U chassis restricts airflow, so sustained all-core turbo clocks depend on rack inlet temperature and aisle containment.

Questions sur cet article

What rack height does the 1U R640 chassis occupy?

The chassis occupies a single 1U rack space in a standard four-post rack.

How are the dual Xeon Silver 4110 processors and 768GB DDR4 memory installed at the factory?

Both processors are pre-mounted in the two LGA 3647 sockets and all 24 DIMM slots are populated with 32GB registered ECC modules.

When will the PERC H730P controller's 2GB cache battery need replacement?

The battery-backed cache typically requires a new battery module after three to five years of continuous operation.
