Abstract:
A method for providing redundancy in a virtualized storage system for a computer system is provided. The method includes determining a first set of first logical addresses to provide a virtual storage volume. A redundancy schema is then selected to provide redundancy data for primary data stored in the first set of first logical addresses. A second set of second logical addresses is determined to provide logical storage for the primary data and for the redundancy data. The first set of first logical addresses and the second set of second logical addresses are then mapped and a set of physical storage addresses is selected from a set of physical storage elements. Mapping between the second set of second logical addresses and the set of physical addresses is then performed to provide physical storage for the primary data and the redundancy data stored in the virtual storage volume.
