Abstract:
1. A system comprising: a processor; a heterogeneous data volume comprising a plurality of redundancy groups and storage disks; and an electronic storage medium containing program instructions executable on the processor for: associating each storage disk with a class of storage, wherein each class of storage is associated with data access mechanisms used to read data from and write data to the storage disk; associating a first set of the storage disks with a first class of storage; associating a second set of the storage disks with a second class of storage; associating a first data set with the first class of storage and the second class of storage; and writing the first data set to the heterogeneous data volume using the data access mechanisms associated with the first class of storage, wherein the writing occurs as part of an input/output operation including storing the first data set within the first set of storage disks associated with the first class of storage and storing the first set of data within the second set of storage disks associated with the second class of storage.
