FCP Adapter Load

During our performance tests, we examined the adapter load on the FCP disks.

The data files of the DB2® UDB databases are residing on FCP disks. From the Performance Toolkit for z/VM® we saw that the per adapter load on the FCP adapters using 5 triplets was 0.4 MB/sec per write and 64 KB/sec per read. This resulted in a per adapter load of 2 MB/sec per write and 320 KB/sec per read, which is very low.
