Abstract
Extensions to the Fragment Mapping Protocol are introduced which protect a disk array from malicious client access by exporting file system access information to the storage device. FMP requests received at the storage device can be authorized at a block granularity prior to completion, thereby limiting the exposure of the disk array to malicious clients. Client authorizations can be cached at the storage device to enable the permissions to be quickly extracted for subsequent client accesses to pre-authorized volumes.
