Server Purpose

The Dell PowerEdge R640 is a 2U rackmount server system designed for business workloads such as virtualization, databases, and application hosting. It ships with dual Intel Xeon Gold 6154 processors, 256GB of DDR4 memory, and eight 600GB 10K SAS drives managed by an H730P storage controller.

Target Buyer

This server suits organisations that need a dense 2.5-inch drive platform with integrated 10GbE networking for virtualised environments or data-intensive applications. Buyers requiring GPU acceleration, larger 3.5-inch drive bays, or support for more than two processors should evaluate alternative chassis designs.

Deciding Specification

The 36 total CPU cores across two sockets set the processing ceiling for concurrent virtual machines and database threads; if the workload demands more cores per socket or a higher maximum memory limit than 3TB, this configuration will not meet the requirement.

Questions about this item

Should I pick the 8-bay 2.5" version or a larger chassis for more drive slots?

The 8-bay 2.5" chassis holds exactly eight drives; the installed configuration already uses all bays with 600GB SAS disks, so no further 2.5" slots remain.

What does the 36-core total mean for actual virtualization density?

Two Xeon Gold 6154 CPUs give 20 cores each at 3.0GHz, yielding 36 cores total to schedule virtual machines and containers across.

How fast can the H730P and SAS drives really move data?

The H730P controller manages the eight 600GB 10K SAS drives; each drive runs at 6GB/s interface speed, setting the practical throughput ceiling.
