The whitepaper below provides details on this functionality (See page 50). No software needs to be loaded on the ESX or vCenter servers. The reporting functionality to get VM to LUN level information is very helpful. Certain use cases are also described in the whitepaper.  [URL]
Can anyone point me in the direction of some documentation on this feature with R29?  We have an extensive Vsphere environment and i was wondering it is will benefit us any to use this feature.   Does importing the vCenter or ESX hosts have any impact on the array or virtual environment?  any reboots required?  It looks like i will need to know ESX/vCenter credentials to get this configured.  Thanks
