Abstract:
A method for automatically configuring a mass storage system for measuring system performance, the system comprising a plurality of disk storage elements, each element having at least one hyper and connected to a disk storage controller, the disk storage controller being connected to at least one host computer, the host computer defining a plurality of logical units (LUN's), the storage controller defining in its configuration a front-end hierarchy and a back-end hierarchy, the method comprisingbalancing assignments of LUN's across the back-end hierarchy, and marginally balancing assignments of disk drive elements and hypers of the disk drive elements across the back-end hierarchy, wherein, said marginally balancing of said drive elements comprises monitoring a first set of disk numbers with counts equal to the minimum for the entire system, monitoring a second set of disk numbers with assignment counts equal to a minimum across the first disk adaptor port to be assigned, and selecting, if possible, a disk member from an intersection of the first and second set.
