Abstract
A method, system and apparatus for allowing a mirroring map to be used with more than one piece of data are provided. First, a mirroring map is created and given a name. Then, the name of the mirroring map and the mirroring map itself are stored into the computer system. When a piece of data is to be stored in accordance with the mirroring map any time thereafter, the name of the mirroring map is used to associate the mirroring map with the piece of data.
Claims20
A method of defining a mirroring map for use with different pieces of data, the mirroring map being an identification of one or more physical storage systems and one or more physical partitions in the one or more physical storage systems to use to store one or more copies of a piece of data, the method comprising the steps of:
- creating the mirroring map;
- naming the mirroring map;
- and
- allowing different pieces of data to be used with the mirroring map when the name of the mirroring map is associated with the different pieces of data.
A computer program product on a computer readable medium for defining a mirroring map for use with different pieces of data, the mirroring map being an identification of one or more physical storage systems and one or more physical partitions in the one or more physical storage systems to use to store one or more copies of a piece of data, the computer program product comprising:
- code means for creating the mirroring map;
- code means for naming the mirroring map;
- and
- code means for allowing different pieces of data to be used with the mirroring map when the name of the mirroring map is associated with the different pieces of data.
An apparatus for defining a mirroring map for use with different pieces of data, the mirroring map being an identification of one or more physical storage systems and one or more physical partitions in the one or more physical storage systems to use to store one or more copies of a piece of data, the apparatus comprising:
- means for creating the mirroring map;
- means for naming the mirroring map;
- and
- means for allowing different pieces of data to be used with the mirroring map when the name of the mirroring map is associated with the different pieces of data.
A computer system for defining a mirroring map for use with different pieces of data, the mirroring map being an identification of one or more physical storage systems and one or more physical partitions in the one or more physical storage systems to use to store one or more copies of a piece of data, the computer system comprising:
- at least a memory device for storing code data;
- and
- at least a processor for processing said code data for creating the mirroring map, naming the mirroring map, and allowing different pieces of data to be used with the mirroring map when the name of the mirroring map is associated with the different pieces of data.
