In our USENIX paper we describe how we do erasure coding in Windows Azure Storage. For erasure coding, we introduce a new set of codes we call Local Reconstruction Codes (LRC). LRC reduces the number of erasure coding fragments that need to be read when reconstructing da...

以微软Azure的云存储(Windows AzureStorage)实现为例,它采用LRC(12,2,2)编码,将12个数据块为一组编码,并进一步将这12个数据块平均分为2个本地组,每个本地组包括6个数据块,并分别计算出一个local parity,之后把所有12个数据块计算出2个global parities。 当发生任何一个数据块错误时,只需用本地组内的数据和...
