The XP24000/XP20000 introduced a new storage allocation concept called Thin Provisioning (ThP). Thin provisioned storage allows the array administrator to pre-plan user capacity needs and allocate virtual storage based on the planned future capacity, but physically only consume the amount of disk space that the user is actually accessing. As a result, administrators no longer have to concern themselves with unused storage - that has been allocated but is not currently in use by the users. This white paper provides an overview of the best practices for setting up XP Thin Provisioning (ThP) on the XP24000/XP20000 array.
