....independent 19 sets of storage servers. Swift incorporates data management techniques long present in centralized computing systems into a distributed environment. In particular, it can be viewed as a generalization to distributed systems of I O channel architectures found in mainframe computers [15]. 6 Conclusions This paper presents Swift, a scalable distributed I O system that achieves high data rates by striping data across several storage servers and driving them concurrently. The system validates the concept of distributed disk striping in a local area network. Swift presents a ....

.... a computer s I O bus through a host bus adapter [ANSI86] In contrast to pre SCSI storage devices, whose interfaces exposed data rates, disk geometry [McKusick84] data dependent addressing [Ahearn72] and bufferless speed matching (causing so called rotational positioning reconnect miss delays [Buzen86]) SCSI decouples storage component interfaces from the host s storage interface, enabling rapid introduction of incremental technology advances. Moreover, the adoption of SCSI (and its less expensive contemporary, IDE) across a broad range of the marketplace has increased competition among disk ....
