The basic block I\/O interface used for interacting with storage devices hasn\u2019t changed much in 30 years. With the advent of very fast I\/O devices based on solid-state memory, it becomes increasingly attractive to make many devices directly and concurrently available to many clients. However, when multiple clients share media at \ufb01ne grain, retaining data consistency is problematic: SCSI, IDE, and their descendants don\u2019t o\ufb00er much help. We propose an interface to networked storage that reduces an existing software implementation of a distributed shared log to hardware. Our system achieves both scalable throughput and strong consistency, while obtaining signi\ufb01cant bene\ufb01ts in cost and power over the software implementation.<\/p>\n","protected":false},"excerpt":{"rendered":"
