Architected and Designed for Virtualization Performance

Architected for Virtualization Performance

The Dell PowerEdge R905 rack server was designed for architected performance and streamlined virtualization deployment. It’s fine-tuned to provide virtualization performance with an ideal formula of processor technology, memory capacity and I/O (input/output) scalability. Featuring up to twice the memory and I/O scalability of the previous-generation, standard 4U four-socket servers, the PowerEdge R905 helps remove the barriers to running memory and I/O-bound applications like VMware® ESX Server. The PowerEdge R905 also allows you to start migrating real virtual machines within a few clicks of a mouse, streamlining deployment in virtualized environments.

Dell’s virtualization strategy is to help you manage your infrastructure with the tools you already have, which is why we work with industry leaders to deliver an integrated solution for managing physical and virtual infrastructures.
