Abstract
The present invention provides a system of hardware and software that combine to efficiently integrate the various requirements for system performance and system reliability in a RAID system. A user of the present invention is able to select from a range of system performance and reliability configurations, independently of each other. From user specifications, the present invention initially constructs a user space which must be mapped onto the physical storage space in the array of disk drives. The present invention preserves the orthogonality of performance and reliability concepts through a series of mappings that relate to these concepts independently as it transforms user space into the physical space of the disk array.
