The primary intent of the Arbutus Open Servers is to provide organizations with an alternative way to stage and access mainframe data. CPU usage costs and resource availability on the mainframe can be a concern in some organizations. Flat files can be moved to the open server with existing file transfer technology, without conversion. VSAM, DB2 and IMS data can also be extracted directly to the open server using the Arbutus technology. Once the data is staged on the server, the data access and integration capabilities of Legacy Link can then be utilized.
