The HP 3PAR InServ storage system provides the University with its Type 1 "performance" storage. This system is a revolutionary form of SAN storage with a number of innovative features found only on high-end enterprise arrays.
Most servers clients use a low proportion of the total storage they are allocated. Thin provisioning allows the array to allocate storage only when it is used. This means that the storage can be "over-allocated", making the array seem much bigger than it is. A space saving in excess of 50% is quite common. The rest of the storage does not need to be installed until it is going to be used; on some systems the space is never completely used, and the extra storage never needs to be purchased at all.
Because of this, thin provisioning gives organizations the ability to support their storage needs with much fewer disk drives. This in turn can cut energy consumption and the production of greenhouse gasses while saving on capacity and energy costs.

Migration “fat to thin”
Using thin provisioning, existing volumes can be migrated onto the storage array, automatically reclaiming the empty space that has not yet been used. Also, when existing data is erased correctly, space can be reclaimed and will be reused in preference to requesting additional storage space.
Storage allocated from all disks evenly
This gives very fast response, as data is less frequently requested from the same disk at the same time. No disk is overworked in comparison to another, so no maintenance “hot spots”.
Excellent random I/O performance
Due to the way storage comes from all across the array, there is much less waiting for a piece of data to be available and so the access times for random disk I/O are much better than for traditional storage arrays. This is particularly good for virtualised server infrastructures such as VMWare.
Different storage technologies and disk layouts provide varying levels of performance. The 3PAR arrays can move storage volumes between these configurations without significantly affecting the storage clients.
