DELL PowerEdge R640 1U Rack Server Dual Xeon 6148 2.40 GHz 512GB 30.72TB

Built for dense virtualization

This Dell PowerEdge R640 1U rack server ships with dual Xeon Gold 6148 processors, each offering 20 cores at 2.40 GHz with turbo up to 3.70 GHz. The platform includes 512 GB of DDR4 memory across 16 modules and 30.72 TB of enterprise SATA SSD storage in eight 3.84 TB drives. A PERC H730 RAID controller with 2 GB NV cache manages the array, while iDRAC9 Express handles remote management. Memory and drives are supplied separately for on-site installation.

Sustained load behaviour

Redundant hot-swappable power supplies allow a failed unit to be replaced without taking the server offline, keeping critical workloads running continuously. The quad-port 1 GbE Broadcom BCM5720 controller provides consistent network throughput for virtualization and software-defined storage tasks. Unbuffered DDR4 memory at 3200 MHz supports steady data feed to all 40 cores during extended compute sessions. The 1U form factor fits standard racks where space and cooling are constrained.

Pre-order checklist

Verify that your rack provides adequate airflow for a 1U dual-socket server with redundant power supplies and eight 2.5-inch drive bays. Confirm that on-site staff can install the 16 memory modules and eight SSDs, as they arrive uninstalled. Ensure your management network can reach the iDRAC9 Express port for out-of-band control. Check that existing cabling and PDU connectors match the dual power supply inputs before scheduling deployment.
