Abstract: A semi-static distribution technique distributes parity across disks of an array. According to the technique, parity is distributed (assigned) across the disks of the array in a manner that maintains a fixed pattern of parity blocks among the stripes of the disks. When one or more disks are added to the array, the semi-static technique redistributes parity in a way that does not require recalculation of parity or moving of any data blocks. Notably, the parity information is not actually moved; the technique merely involves a change in the assignment (or reservation) for some of the parity blocks of each pre-existing disk to the newly added disk.

Abstract translation: 半静态分配技术在阵列的磁盘上分配奇偶校验。 根据该技术，奇偶校验以在盘的条带之间维持奇偶校验块的固定模式的方式分布（分配）在阵列的盘上。 当将一个或多个磁盘添加到阵列中时，半静态技术以不需要重新计算奇偶校验或移动任何数据块的方式重新分配奇偶校验。 值得注意的是，奇偶校验信息实际上没有被移动; 该技术仅涉及将每个预先存在的磁盘的一些奇偶校验块的分配（或预留）改变为新添加的磁盘。

Abstract: A network caching system has a multi-protocol caching filer coupled to an origin server to provide storage virtualization of data served by the filer in response to data access requests issued by multi-protocol clients over a computer network. The multi-protocol caching filer includes a file system configured to manage a sparse volume that “virtualizes” a storage space of the data to thereby provide a cache function that enables access to data by the multi-protocol clients. To that end, the caching filer further includes a multi-protocol engine configured to translate the multi-protocol client data access requests into generic file system primitive operations executable by both the caching filer and the origin server.
