摘要:
An embodiment of the invention provides an apparatus and method for optimizing reads in a mirrored file system. The apparatus and method receives a plurality of read request blocks for reading the target regions in disks. The apparatus and method will chain the read request blocks in a first set, where all of the read request blocks in the first set are targeted to a first disk. The read request blocks in the first set are then sent as a read request to the first disk. When each read request block in the first set has completed accessing their respective target regions in the first disk, then the read data is generated from the first disk. Therefore, by chaining the read request blocks in a read request to a single disk, read striping is not performed across multiple disks during a read operation.
