1U rack server with dual 8-core Xeon Silver 4110 CPUs, 512GB DDR4 ECC memory, PERC H730P RAID controller, eight 600GB 10K SAS drives, quad-port 1GbE/10GbE networking, iDRAC9 Enterprise.
The Dell PowerEdge R640 is a dual-socket 1U rack server built for dense scale-out data center computing. Two Intel Xeon Silver 4110 processors each run eight cores at 2.1 GHz with a 3.0 GHz turbo frequency. The system ships with 512 GB of DDR4 2400 MHz registered ECC memory across sixteen 32 GB modules. Eight 600 GB 10K SAS 2.5-inch drives provide high-speed storage capacity.
Redundant hot-swap 750 watt platinum efficiency power supplies deliver reliable power with failover protection. The Intel C620 chipset manages platform I/O and processor communication. The 1U form factor maximises rack density while supporting up to two processors and 24 memory slots for future expansion. Hot-swap power supplies allow maintenance without system downtime.
The PERC H730P 2 GB controller supports RAID 0/1/5/6/10/50/60 and pass-through modes with battery-backed cache. An Intel X520/I350 quad-port network daughter card provides two 1 GbE and two 10 Gb SFP+ connections. iDRAC 9 Enterprise enables comprehensive remote management and monitoring. Ready rails and front bezel are included for immediate rack installation.

Seat the PERC H730P in the dedicated internal storage slot, connect the SAS cables to the backplane, then install the 2 GB battery pack and enable the controller in the BIOS before creating any virtual disks.
The eight 600 GB 10K SAS drives are mechanical; plan to replace any that develop SMART errors or exceed their rated workload. The PERC H730P’s 2 GB battery typically lasts 3‑5 years and should be swapped when the iDRAC9 reports a degraded state.
With two 8‑core Xeon Silver 4110 processors at 2.1 GHz (3.0 GHz turbo) in a 1U chassis, the thermal envelope of the 750 W redundant power supplies and the 24‑DIMM memory subsystem becomes the bottleneck before CPU or storage throughput saturates.
