If you are concerned about performance, with that many users, you should
really consider a box like the EMC or XP-256. If the price is an issue,
then consider instead using the 12H for only the system volume set, and
move all user data/applications to private volumes on JBOD with disk
mirroring. It keeps the price down and still gets reasonable
performance.
Have you requested HP, or EMC look at your system and propose solutions?
