....of disk devices and the higher data rates mandated by new applications is to use several disks in parallel. Much like memory interleaving, faster secondary storage systems can be built from a collection of slower storage devices. Several concurrent I O architectures, such as Imprimis ArrayMaster [1], DataVault [2] CFS [3] and Raid [4, 5] are based on this observation. Swift uses this approach to achieve any required data rate to secondary storage up to saturation of the interconnection medium. Figure 1 has a diagram of the architectural structure of Swift. The Swift architecture ....

....storage devices and driving them in parallel. The principle behind our architecture is simple: aggregate arbitrarily many (slow) storage devices into a faster logical service, making all applications unaware of this aggregation. Several concurrent I O architectures, such as Imprimis ArrayMaster [4], DataVault [5] CFS [6, 7] and Raid [3, 8] are based on this observation. Mainframes [9, 10] and super computers [11] have also exploited this approach. 1 Unix is a trademark of AT T Bell Laboratories 2 Distribution Agent .

....distributed environment, striping files over multiple servers. Examples of some commercial systems that utilize disk striping include super computers [11] DataVault for the CM 2 [5] the airline reservation system TPF [9] the IBM AS 400 [10] CFS from Intel [6, 7] and the Imprimis ArrayMaster [4]. Hewlett Packard is developing a system called DataMesh that uses an array of storage processors connected by a highspeed switched network [19] For all of these the maximum data rate is limited by the interconnection medium which is an I O channel. Higher data rates can be achieved by using ....
