I'm struggling a little with Jetstress and how to run it to get a "real-world" test of Exchange performance.
If I run the mailbox test with an IOPS profile of 0.2 and 500 mailboxes each of 100mb (smallish LUN just to do some quick testing) I get: Database Sizing and Throughput Achieved Transactional I/O per Second 135.2 Target Transactional I/O per Second 100 Initial Database Size (bytes) 90580779008 Final Database Size (bytes) 90689830912 Database Files (Count) 1 But if I run the performance test I'm seeing this: Database Sizing and Throughput Achieved Transactional I/O per Second 1374.757 Capacity Percentage 100% Throughput Percentage 100% Initial Database Size (bytes) 86008987648 Final Database Size (bytes) 90580779008 Database Files (Count) 1 So naturally I'm a little confused on how to get "real-world" figures in and out of it? The array is a HP P4000 24x600gb 15k SAS iSCSI SAN. It's not solely dedicated to Exchange but the point is that it's not slow in terms of throughput or IOPS so I suspect the problem is with what I'm telling Jetstress to do. Any advice would be great.
