There are four front-end I/O modules per node on the PowerStore 1000T used in our validation. Front-end I/O modules communicate with a Fibre Channel switch to the PowerEdge servers. An optimized configuration for databases is one where the number of front-end I/O modules is maximized. Maximizing the number of front-end I/O modules reduces the possibility of a bandwidth bottleneck and optimizes overall database storage performance.
The following two configurations were tested in validating the storage configuration:
Results showed improved database performance when all 4 front-end I/O ports from the two PowerStore nodes were zoned to the PowerEdge servers.
