P9000 Provisioning for Open Systems User
Guide
Abstract
This guide describes and provides instructions for using HP P9000 provisioning software to configure and perform its operations
on HP P9500 disk arrays. Provisioning software includes Thin Provisioning, Smart Tiers, Open Volume Management (Virtual
LUN and LUSE), LUN Manager, and Data Retention. The intended audience is a storage system administrator or authorized
service provider with independent knowledge of HP P9000 disk arrays and the HP Remote Web Console.
