Dell PowerEdge r740: Specs and Rack Compatibility


The Dell PowerEdge R740 made several improvements over the previous generation with the ability to support 1.5x more virtual desktops, M.2 boot optimized storage and more PCIe lanes thanks to Intel’s Scalable processors.

Released in 2017, the PE R740 still sells on Dell’s official website with a base price of $3600. This server has more advanced features than the R540, released in the same years, which explains the increased price.
