NetWare 6 is a reliable, highly-scalable version of NetWare which takes advantage of high-powered Multi-Processor (MP) server hardware by MP-enabling the complete packet transfer from the wire to the storage media. This AppNote provides background information about NetWare 6’s MP functionality and explains how MP-enabled programs run on NetWare 6. It details the MP-related improvements made in NetWare 6 and discusses development opportunities for the new OS. | Multiprocessing Support in NetWare 6 Feature Article I NOVELLAPPNOTES Kevin Burnett Senior Research Engineer Novell AppNotes kburnett@novell. com NetWare 6 is a reliable highly-scalable version of NetWare which takes advantage of high-powered Multi-Processor MP server hardware by MP-enabling the complete packet transfer from the wire to the storage media.

Actually it could be looked at as being a third generation as you will see from this short history. Novell introduced MP functionality with NetWare . This first attempt was somewhat limited in functionality in that the core operating system OS was not MP-enabled. All of the core OS functionality had to be funneled to processor 0 which is the default processor that threads are run on when the application is not MP-compliant. This version of NetWare allowed applications that were written to the MP standard to run on processors other than processor 0. But any time the application needed to use core OS functionality disk access transmit on the wire and so on the request had to be reverted back to processor 0. Hence it was not a complete solution. With the advent of NetWare 5 the MP .
