We also have our ITSM DATABASE (5.2.8.1/AIX 5.2ML5/Powerpath 4.5.1) on Clariion CX600 with 10k disk (146GB) on p695 partition (4 processors/8GB memory). But we have among 55Mo/s (20 <=> 80) troughput for each hdiskpower in dual path with load balancing. We have 4 luns (each 50GB) all created on 4 +1 RAID Group (4+1 is optimized for write and read) balance between the 2 storage processors for the db. Inventory run in about 3<->6 hours. dbfile is build with file of 10GB.
