A protocol family shifts the decision of which types of faults from implementation time to data-item creation time. If desired, each data-item can be protected from different types and numbers of faults. This paper describes and evaluates a family of storage access protocols that exploit data versioning to efficiently provide consistency for erasure-coded data. This protocol family supports a wide range of fault models with no changes to the client-server interface or server implementations. Its members also shift overheads to clients. Readers only pay these overheads when they actually observe concurrency or failures. Measurements of a prototype block-store show the efficiency and scalability of protocol family members. 2003-12-01 00:00:00 survivable storage protocol family Byzantine fault-tolerance atomic registers erasure codes
