Question

A customer has a long standing environment on an AIX platform for an application which has 300 volumes assigned to it. The reason given by the customer for such a high number of volumes is to allow the application to spread its workload out across these devices because only 1 transaction per volume is allowed to be outstanding at any one time. The technical specialist is consolidating the environment to a smaller number of volumes on a Storwize V7000. Assuming that the application will support the use of a smaller number of volumes, what adjustment can the technical specialist recommend to allow the number of outstanding I/O operations on each volume be increased to maintain performance?
