Dense Scale-Out Server

The Dell PowerEdge R640 is a dual-socket 1U rack server built for dense scale-out data centre computing. It combines high core density with redundant hot-swap power supplies and integrated remote management. Two Intel Xeon Gold 6148 processors deliver 40 total cores at a base frequency of 2.4 GHz with a 3.7 GHz turbo boost. The system ships with 128 GB of DDR4 2666 MHz registered ECC memory across eight 16 GB modules.

Suited For Virtualisation And Database Workloads

This configuration suits organisations running virtualisation clusters, database instances or high-performance computing tasks that benefit from 20-core processors and hardware RAID. The PERC H730P controller supports RAID levels 0, 1, 5, 6, 10, 50 and 60 with a 2 GB battery-backed cache. Buyers who need more than 3 TB of total memory capacity or who require all-flash arrays should evaluate other platforms.

Storage Capacity And Drive Type Decide Fit

The chassis holds eight 2.5-inch drive bays populated with 300 GB 10K SAS hard drives, providing 2.4 TB of raw spinning-disk capacity. The SAS interface and 12 Gb/s controller bandwidth determine throughput for RAID arrays. If the workload demands larger solid-state capacity or a different drive interface, this specific drive set will not meet the requirement.
