Host computer I/O filter re-directing potentially conflicting I/O commands from instantiations of legacy application

摘要

A host computing device has multiple instantiated copies of a legacy application. Each copy may issue a data request to access data at an absolute location common to all of the copies. To respond to the data request from a particular copy, it is determined that the absolute location of the data request has a redirection device specifying an alternate location, and the data request is dishonored. A unique location is determined from the alternate location and a unique ID of the particular copy of the legacy application, and the data request is re-issued to access the data at the unique location. Data requests from different copies of the legacy application are thus directed to different unique locations.
