  • Redundant power supplies and iDRAC9 remote management keep the server running

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.

Questions about this item

How much heat does the dual Xeon 6148 configuration generate when running continuously?

Two 20-core Xeon Gold 6148 CPUs at 2.40 GHz base and 3.70 GHz turbo draw significant power under load; the redundant hot-swap power supplies handle the thermal output without shutting the server down.

What infrastructure must I already have to install this 1U rack server?

A standard rack cabinet, two AC power circuits for the redundant supplies, and network cabling for the quad-port 1 GbE controller are required before the server can operate.

Will the PERC H730 RAID controller work with my existing 6 Gb/s SATA SSDs?

The PERC H730 12 Gb/s RAID controller with 2 GB NV cache supports SATA III 6 Gb/s drives, so older enterprise SSDs using that interface can be added to the array.
