Mirrored disk systems provide high reliability by multiplexing disks. Performance is improved with parallel reads and shorter read seeks. However, writes must be performed by both disks, limiting performance.We introduce distorted mirrors, a mirroring system which combines write anywhere semantics with traditional database-specified block locations. This technique radically reduces the cost of small writes, making it attractive for random access applications such as OLTP, while retaining the ability to efficiently perform large sequential accesses. Distorted mirrors also scale better than traditional mirrors in terms of both disk caching and large mirrored sets. We show the effectiveness of distorted mirrors on the TP1 benchmark.
