Configurable views of archived data storage
First Claim
1. A method for creating a view for a plurality of data units, wherein a portion of the plurality of data units are stored in one or more storage drives that are in a lower power mode of operation in the storage system, the method comprising:
- determining a subset of data units stored in a storage system based on one or more filter criteria;
determining metadata representing the subset of data units in the storage system;
creating a view using the metadata; and
storing the view such that it is always accessible on a powered on storage drive, wherein the metadata is for one or more data units in the subset of the data units are stored in one or more storage drives that are in the lower power mode of operation.

Abstract
In one embodiment, a method for creating a view for a plurality of data units is provided. A portion of the plurality of data units are stored in one or more storage drives that are in a lower power mode of operation in the storage system. The method includes determining a subset of data units stored in a storage system based on one or more filter criteria. Metadata is determined that represents the subset of data units in the storage system. A view is then created from the metadata. For example, a dynamic or static view may be created. The view is then stored such that it is always accessible on an always on storage drive. The metadata may be used to provide information about the data units in the storage drives that are in a lower power mode of operation without having to power on the storage drives.

10. An apparatus configured to create a view for a plurality of data units, wherein a portion of the plurality of data units are stored in one or more storage drives that are in a lower power mode of operation in the storage system, that apparatus comprising:
-
one or more processors; and
logic encoded in one or more tangible media for execution by the one or more processors and when executed operable to;
determine a subset of data units stored in a storage system based on one or more filter criteria;
determine metadata representing the subset of data units in the storage system;
create a view using the metadata; and
store the view such that it is always accessible on a powered on storage drive, wherein the metadata is for one or more data units in the subset of the data units are stored in one or more storage drives that are in the lower power mode of operation. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. An apparatus configured to create a view for a plurality of data units, wherein a portion of the plurality of data units are stored in one or more storage drives that are in a lower power mode of operation in the storage system, the apparatus comprising:
-
means for determining a subset of data units stored in a storage system based on one or more filter criteria;
means for determining metadata representing the subset of data units in the storage system;
means for creating a view using the metadata; and
means for storing the view such that it is always accessible on a powered on storage drive, wherein the metadata is for one or more data units in the subset of the data units are stored in one or more storage drives that are in the lower power mode of operation.
