PowerEdge VRTX is a shared infrastructure solution designed for small or branch offices as it simplifies IT by combining all of this infrastructure in a single unit, eliminating the need for a lot of cabling and complexity, and allowing for management of these resources from a GUI single interface. The detailed specification of VRTX is available at Dell website.

VRTX integrates servers, storage, networking and management into a single office-optimized chassis in the size of a tower server (or 5U rack).

VMware ESXi 5.1 Update 1 is the supported VMware ESXi version for the sever nodes on PowerEdge VRTX. The RAID controller used in VRTX is "Shared PERC8" for the shared storage management. The driver for Shared PERC8 (the low-latency internal shared storage) is included from the Dell customized VMware ESXi 5.1 Update 1 Image (A01 Revision) which can be downloaded from  support.dell.com.

Note: Earlier revisions (A00) of the Dell Customized VMware ESXi 5.1 Update1 Image does not support Shared PERC8 feature.

The server nodes Dell PowerEdge M520 & M620 are supported on Dell PowerEdge VRTX with BIOS Version 1.7.6 and above.

Dell starts shipping VMware ESXi 5.1 Update 1 (Dell Customized A01 revision) image from factory on all supported server nodes from 6/25/2013.
