Abstract:
A method of providing a storage space for a computer system, comprising the steps of:partitioning each of a first and a second of at least two physical data storage devices into primary and secondary storage spaces, wherein the primary storage space of the first physical data storage device has a faster average seek time than the secondary storage space of the second physical data storage device, and wherein the primary storage space of the second physical data storage device has a faster average seek time than the secondary storage space of the first physical data storage device; defining a logical storage space within a storage controller connected to the physical data storage devices, wherein (i) a first portion of the logical storage space is defined to correspond to the primary storage space of the first of the at least two physical data storage devices, and correspond to the secondary storage space of the second of the at least two physical data storage devices, and (ii) a second portion of the logical storage space is defined to correspond to the primary storage space of the second physical data storage device, and correspond to the secondary storage space of the first physical data storage device.
