dedup in SAN environment

How should volumes / LUNs be setup to gain maximum benefit from deup in a VMware SAN environment (No of LUNs per volume, space guarantees, reservations, when to de dup etc).

Re: dedup in SAN environment

Still a work in progress but this is what I have been playing with.

Re: dedup in SAN environment

An example:

A 1TB volume with a 950GB LUN both thin – 800GB’s worth of VMs are added to the LUN – Duplication is ran – The 800GB has reduced to 300GB.

How is free space reclaimed in the aggregate?

Does the LUN and volume shrink (from the storage perspective) down to 300 ish GB ??

Many thanks for this Teresa.
