ABSTRACT:
The functions of two virtual operating systems (e.g., S/370 VM and S/88 OS) are merged into one physical system. Partner pairs of S/88 processors run the S/88 OS and handle the fault tolerant and single system image aspects of the system. One or more partner pairs of S/370 processors are coupled to corresponding S/88 processors directly and through the S/88 bus. The S/370 processors are alien to the S/88 Operating System, i.e., not in its configuration tables. Means are provided to isolate partner pairs of S/88 processors from the S/88 Operating System and couple the S/88 processors directly to corresponding pairs of S/370 processors for interaction therewith, transparent to the S/88 Operating System.
