Abstract
Official abstract text for this publication.
A storage server receives a write request from a client system including new data and a location to store the new data. The storage server transmits a copy instruction to a storage subsystem to relocate old data at the location and transmits a write instruction to the storage subsystem to overwrite the old data with the new data. The storage subsystem includes fast stable storage in which the copy instruction and the write instruction are stored. After receiving each instruction, the storage subsystem sends an acknowledgement to the storage server. When both instructions have been acknowledged, the storage server sends an acknowledgement to the client system. The storage subsystem performs the instructions asynchronously from the client system's write request.
First claim
Opening claim text (preview).
What is claimed is: 1. A computer-readable non-transitory storage medium having stored thereon executable instructions that, when executed by one or more processors of a storage server, cause the storage server to: receive a write request from a client system, the write request comprising data to be written and a location in a storage space; transmit a copy instruction to a storage subsystem, the copy instruction indicating to copy existing data at the location in the storage sp…
