Dell PowerEdge R640 10-Bay Virtualization Server

The Dell PowerEdge R640 is a 1U rack server equipped with two Intel Xeon Gold 6148 processors running at 2.40GHz. It delivers 40 total cores and 128GB of DDR4 memory for virtualization, databases, and business applications. Ten 2.5-inch bays come populated with 600GB 10K SAS hard drives.

Sustained Load Behaviour

Dual 20-core Xeon Gold 6148 processors maintain steady throughput for multi-tenant workloads, virtualization clusters, and database services. The 128GB DDR4 capacity supports many concurrent virtual machines without excessive paging. Ten 600GB SAS drives provide consistent I/O for mixed read-write patterns under continuous demand.

Pre-Installation Checks For Rack Deployment

Verify the rack provides a 1U slot and adequate airflow for front-to-rear cooling in a dense configuration. Confirm the SAS backplane and controller match the installed 10K drives and that your infrastructure supports the X540/I350 network interfaces. Ensure power distribution can handle the 55 unit weight and redundant supply requirements.
