Abstract
As network latency drops below disk latency, access time to a remote disk will
begin to approach local disk access time. The performance of I/O may then be
improved by spreading disk pages across several remote disk servers and
accessing disk pages in parallel. To research this we have prototyped a data
page server called a Page File. This persistent data type provides a set of
methods to access disk pages stored on a cluster of remote machines acting as
disk servers. The goal is to improve the throughput of database management
system or other I/O intensive application by accessing pages from remote disks
and incurring disk latency in parallel. This report describes the conceptual
foundation and the methods of access for our prototype.
