Abstract:
A method includes distributively encoding data stored in a storage system using an erasure-correcting code. The encoded data is distributed into multiple w storage device arrays in the storage system. Each storage device array includes n storage devices. Each storage device is divided into m sectors or pages. The n storage devices are grouped into l groups of t storage devices each. Data erasures in the w storage device arrays are corrected by recovering erased data using the erasure-correcting code of un-erased data based on each row and column in each m×n array being protected by the erasure-correcting code for the data. Each group of t storage devices contains extra second responder parities to correct extra data erasures in addition to data erasures corrected by first responder vertical parities in each m×t subarray, and w, n, m, l and t are positive integers.

Claim (Index 1):
A method for distributed hierarchical data recovery processing comprising:\n distributively encoding data stored in a storage system using an erasure-correcting code; distributing the encoded data into a plurality of w storage device arrays in the storage system, each storage device array including n storage devices, each storage device divided into m sectors or pages; grouping the n storage devices into l groups of t storage devices each; and correcting data erasures that occurred in the plurality of w storage device arrays by recovering erased data using the erasure-correcting code of un-erased data based on each row and column in each m\u00d7n array being protected by the erasure-correcting code for the data, wherein each group of t storage devices contains extra second responder parities to correct extra data erasures in addition to data erasures corrected by first responder vertical parities in each m\u00d7t subarray, and w, n, m, l and t are positive integers.
