Placement of MQ log and data files

If your system has to be able to process a high message rate, you may should consider placing your MQ log and data files on a fast SAN, preferably configured with a large NVRAM and RAID-10. A single internal disk should have sufficient capacity to allow up to 150K to 200K messages per second. Files on a RAID-10 LUN should be able to get up to around 1.5M to 2.0M messages per hour. Beyond that message rate, you may want to consider implementing multiple queue managers with separate data and log files.
