The project is reaching its culmination with the

implementation of a prototype disk array file server with a

capacity of 40 GBytes and a sustained bandwidth of 80

MBytes/second. The server is being interfaced to a 1 Gb/s

local area network. A new initiative, which is part of the

Sequoia 2000 Project, seeks to construct a geographically

distributed storage system spanning disk arrays and automated

libraries of optical disks and tapes. The project will

extend the interleaved storage techniques so successfully

applied to disks to tertiary storage devices. A key element

of the research will be to develop techniques for managing

latency in the I/O and network paths.
