Purpose-built 1U server for virtualisation workloads

The Dell PowerEdge R640 SFF is a 1U rackmount system designed for business workloads such as file storage, virtualisation, databases, backups and application hosting. Two Intel Xeon Gold 6146 processors at 3.20 GHz with 12 cores each deliver dependable performance for multi-service environments. 192 GB of DDR4 memory supports multiple virtual machines and data-heavy applications simultaneously.

Storage density limited by ten 2.5-inch bays

The chassis provides ten 2.5-inch drive bays, five of which are populated with 512 GB SSDs for operating systems, applications, virtual machines and business data. The H740P storage controller simplifies array configuration and day-to-day management. Remaining bays allow capacity expansion but the physical limit of ten bays constrains maximum internal storage.

Rack-ready build with front status LEDs

The unit weighs 60 units and fits a standard 1U rack footprint for straightforward mounting. Front-panel LEDs for power, Ethernet and USB give immediate visual status without opening the chassis. Hot-plug drive carriers enable drive swaps while the server remains online, reducing downtime during maintenance or capacity changes.

Questions about this item

Should I choose the 192GB DDR4 configuration or add more memory up to the 3TB maximum?

The system ships with 192GB DDR4 installed; the platform supports up to 3TB total so you can expand later if workloads grow beyond the current capacity.

What does the 3.20GHz Xeon Gold 6146 speed mean for my virtualization workloads?

Each of the two Gold 6146 processors runs at 3.20GHz with 12 cores, delivering consistent clock speed for responsive VM performance.

How does the H740P controller affect the 5x 512GB SSDs in the 10-bay 2.5" chassis?

The H740P RAID controller manages the five 512GB SSDs across the ten 2.5-inch bays, providing hardware RAID for data protection and performance.
