Abstract
Embodiments of the present invention generally provide for multi-dimensional disk arrays and methods for managing same and can be used in video surveillance systems for the management of real-time video data, image data, or combinations thereof.
Claims20
A method, comprising:
- providing data redundancy across a plurality of disk drives at a node, wherein the plurality of disk drives and the node are included in a first level disk array;
- forming, by a cross-node manager, a second level disk array based on the disk drives of the node;
- restoring data using the second level disk array responsive to failure of the node receiving an indication of unavailability of a particular disk of the second level disk array;
- and
- setting bits of a bitmap corresponding to locations of the particular disk.

A non-transitory computer readable medium comprising instructions that when read by a processor perform:
- providing data redundancy across a plurality of disk drives at a node, wherein the plurality of disk drives and the node are included in a first level disk array;
- forming, by a cross-node manager, a second level disk array based on the disk drives of the node;
- and
- setting bits of a bitmap corresponding to locations of a particular disk of the second level disk array.
