Virtualisation rack server

Dell PowerEdge R640 is a 1U rack server built for business workloads such as virtualisation, databases and application hosting. Two Intel Xeon Gold 6154 processors deliver 36 cores at 3.0 GHz. 128 GB DDR4 memory and an H730P controller come pre-installed. Eight 2.5-inch bays hold 600 GB 10K SAS drives.

Suitable buyers and limits

This server suits teams that need dense compute and internal SAS storage for virtual machines or file services. The dual-socket design maximises core count in a single rack unit. Buyers who need more than two processor sockets should look at a different platform. Workloads requiring dedicated GPU acceleration are not supported by the integrated graphics.

Deciding specification

The eight 2.5-inch SAS bays with 600 GB 10K drives set the storage foundation. This capacity and drive type determine how many virtual machines, databases or backups fit locally. If your dataset exceeds the available space, you must add external storage or choose a chassis with more bays.

Questions about this item

At what memory capacity does the system reach its DDR4 limit?

The board supports up to 3TB of DDR4 across its slots, so the 128GB installed leaves room for expansion.

How loud or hot does the 1U chassis get when both 3.0GHz Xeon Gold 6154 CPUs run at full load all day?

Dual 18-core processors at 3.0GHz in a 1U form factor move significant heat; expect high fan speeds and front-to-rear airflow demand under sustained load.

Which storage controller must already be present to manage the eight 600GB SAS drives?

The H730P RAID controller is included and required to configure and run the 8-drive SAS array.
