摘要

A computer-implemented method, according to one embodiment, includes: selecting strips from each storage unit for a given erasure code stripe such that the given erasure code stripe includes at most one strip from a high failure rate region of the respective storage unit, where each of the storage units include high and low failure rate regions. The selected strips are organized such that a number of each strip in the given erasure code stripe is offset from the remaining strips by an amount that is greater than a total number of strips in the high failure rate regions. The organized selected strips are further mapped to form the given erasure code stripe such that the high failure rate regions on each storage unit are mapped to one or more sequentially numbered strips, and the low failure rate regions are mapped to additional sequentially numbered strips.

說明書

Furthermore, looking to FIG. 6B, a representational overview 650 of another in-use example for enabling erasure code protection across a number of optical disks is depicted. It should be noted that the overview 650 according to the present in-use example is in no way intended to limit the invention and may implement any one or more of the approaches that are described herein. As mentioned above, by mapping the unit addresses of the various high failure rate regions on an optical disk such that they have sequential numbered virtual addresses as illustrated, an erasure code stripe which includes at most one strip from the high failure rate region of the respective storage unit may desirably be formed. This is also achieved by organizing the selected strips such that a number (e.g., track number) of each strip in the given erasure code stripe is offset from the remaining strips by an amount that is greater than a total number of strips in the high failure rate regions. For instance, each of the shaded strips 652 have been selected from each of the optical disks 0, 1, 2, 3, 4, 5 such that the track number of each shaded strip 652 is offset from the track numbers of the remaining strips 652. For reference, some of the strips in optical disk 0 have been labeled with the track numbers (i.e., strip 0, strip M/P, and strip M?1) that correspond thereto. As a result, the shaded strips 652 span across the optical disks 0, 1, 2, 3, 4, 5 in a sequential manner as shown in FIG. 6B.
