What is the relationship between a storage volumeand an extent?

A storage volume can be split into multiple extents An extent must map to an entire storage volume A storage volume can be created out of multiple extents An extent can span multiple storage volumes

3.

Why is it EMC best practice that each back-end LUN has a connection to all the A-directors and to all the B-directors in theVPLEX cluster?

Prevents data unavailability during a non-disruptive upgrade Reduces the number of ITLs Ensures writes are mirrored on director local cache Optimizes global read cache
