Terminology wise, a logical disk is somewhat analagous to an emc raid set. 3par doesn't have the fracture in its architecture like emc does with pool luns/traditional luns. We just have the vv. Emc pool luns have a lot of downsides (mostly performance) which is why emc keeps the traditional lun around. 3par was designed around a modern virtualized architecture, so we dont have any of those downsides. As far as maximum size, currently any single vv can be up to 16TiB in size. And yes, max user size is the maximum size for any one vv. |
