Which version of HPSE you have. If you have 6.0 try upgrading it with HPSE6.0 SP4 and you can find a utility "Storage Planner" under the folder (Once you extract it) HPSE6.0 SP4\SESRM_00007(SP4)\Utilities\Windows
Try installing and check it out.. I dont have Visio licence when I tried installing "Storage Planner"
