Abstract
A translation device driver apparatus and method are disclosed. A first type of request is received from a disk-based file system to access a first type of storage device. The first type of storage device permits direct access reads and writes and implements update-in-place data modification wherein individual blocks of data stored in the first type of storage device can be modified individually without invalidating data stored in any other blocks in the first type of storage device. The first type of request is translated into a second type of request. The second type of request is a request for a second type of storage device. The second type of storage device operates in append-only mode. The second type of storage device does not permit update-in-place data modification. The second type of request is forwarded to a storage system. The storage system is designed to be the second type of storage device. The storage system is modified to permit update-in-place data modification.
