Abstract:
Information is maintained in one or more virtual volume aggregates comprising a plurality of virtual volumes. A plurality of virtual volumes is maintained in a first information storage medium, and forms one or more virtual volume aggregates, where each of the of virtual volumes is assigned to one of the virtual volume aggregates. The method further provides a plurality of second information storage media. The method then identifies the least recently used virtual volume, and writes the virtual volume aggregate comprising that least recently used virtual volume to one or more second information storage media. Thereafter, the method determines if space is required on said first information storage medium. If space is required on said first information storage medium, the method selects the virtual volume aggregate comprising the least recently used virtual volume and removes from said first information storage medium each virtual volume in that selected virtual volume aggregate that has been written to one or more second information storage media.

PROBLEM TO BE SOLVED: To maintain information in one or more virtual volume aggregates comprising a plurality of virtual volumes. SOLUTION: A plurality of virtual volumes are maintained in a first information storage medium, and form one or more virtual volume aggregates. Each of the virtual volumes is assigned to one of the virtual volume aggregates. Furthermore, a plurality of second information storage media are provided. Then, the least recently used virtual volume is identified, and the virtual volume aggregate comprising that least recently used virtual volume is written to one or more second information storage media. Thereafter, it is determined if space is required on the first information storage medium. If space is required on the first information storage medium, the virtual volume aggregate comprising the least recently used virtual volume is selected, and each virtual volume in that selected virtual volume aggregate written to one or more second information storage media is removed from the first information storage medium.

Un método para mantener información en uno o más agregados de volúmenes virtuales, que comprende los pasos de: mantener una pluralidad de volúmenes virtuales en un primer medio de almacenamiento de información; formar uno o más agregados de volúmenes virtuales, asignándose cada uno de dicha pluralidad de volúmenes virtuales a uno de dichos uno o más agregados de volúmenes virtuales; prever una pluralidad de segundos medios de almacenamiento de información; identificar el volumen virtual que haga más tiempo que no haya sido usado; y transferir el agregado de volúmenes virtuales que comprenda dicho volumen virtual que haga más tiempo que no haya sido usado a uno o más segundos medios de almacenamiento de información; comprendiendo el método, también, los pasos de: mantener (N) volúmenes virtuales; generar (M) identificadores, siendo (M) > 1; asignar un identificador (j) a uno o más de dichos (N) volúmenes virtuales, siendo (M) >_ (j) >_ 1 asignar uno de dichos (M) identificadores a cada uno de dicha pluralidad de segundos medios de almacenamiento de información; y transferir uno o más volúmenes virtuales que haga más tiempo que no hayan sido usados, cuyo identificador asignado sea (j), a uno o más segundos medios de almacenamiento de información cuyo identificador asignado sea (j).

Abstract:
Information is maintained in one or more virtual volume aggregates comprisin g a plurality of virtual volumes. A plurality of virtual volumes is maintained in a first information storage medium, and forms one or more virtual volume aggregates, where each of the of virtual volumes is assigned to one of the virtual volume aggregates. The method further provides a plurality of second information storage media. The method then identifies the least recently use d virtual volume, and writes the virtual volume aggregate comprising that leas t recently used virtual volume to one or more second information storage media . Thereafter, the method determines if space is required on said first information storage medium. If space is required on said first information storage medium, the method selects the virtual volume aggregate comprising t he least recently used virtual volume and removes from said first information storage medium each virtual volume in that selected virtual volume aggregate that has been written to one or more second information storage media.
