Dense Virtualisation Platform

The Dell PowerEdge R640 is a 1U rack server built for dense virtualisation and high-performance computing. Dual Xeon Gold 6148 processors deliver 40 cores at 2.40 GHz with turbo up to 3.70 GHz. The system includes 256 GB of DDR4 memory across eight 32 GB modules running at 3200 MHz. Fifteen point thirty-six terabytes of enterprise SATA SSD storage are provided by four 3.84 TB drives.

Redundant Power And Quiet Cooling

Dual hot-swappable power supplies allow a failed unit to be replaced without taking the server offline. The PERC H730 RAID controller with 2 GB non-volatile cache manages the storage array while the Broadcom BCM5720 quad-port 1 GbE controller handles network traffic. iDRAC9 Express provides remote management for uninterrupted operations around the clock.

Ready For Rack Integration

The included rail kit enables quick mounting in a standard rack. Four 2.5-inch drive bays are populated with the SSDs, leaving additional bays available for future expansion. Memory slots hold the eight installed modules with room for further upgrades. Windows Server 2022 Standard with a 16-core license is supplied for immediate deployment.

Questions about this item

How do I install the 8 x 32GB DDR4 3200MHz modules in the R640, and which step is commonly missed?

Power down the server, open the chassis, align each DIMM with its slot and press firmly until the retention clips click; the step often missed is confirming the memory configuration in the iDRAC9 BIOS after reboot.

What maintenance will the PERC H730 RAID controller with 2GB NV cache require over time?

Monitor the cache battery health through iDRAC9 and replace the battery module when the controller reports a degraded state to preserve write-back performance.

Which limit appears first on the dual Xeon Gold 6148 CPUs during sustained 3.70 GHz turbo workloads?

The processor thermal ceiling triggers clock throttling before the redundant power supplies reach their output limit.
