This chapter describes a potential consolidation of existing systems that contain some virtual elements. By implementing this consolidation, you can accomplish the following goals:
Consolidate existing Oracle Solaris 11, Oracle Solaris 10, and Solaris 8 servers onto a single SPARC server.
Increase hardware and software efficiency and streamline system maintenance through the exclusive use of virtual environments.
Run applications with different SRUs or update schedules on the same server by using Oracle Solaris kernel zones.
Maintain isolation and perform application monitoring by running each application in its own zone or guest domain.
Figure 2-1 Mapping Existing Systems onto a Single SPARC T5-2 System
The following migrations and consolidations are performed:
Two Oracle Solaris 11.1 systems, Sol11_sys1 and Sol1_sys2, run in the Oracle Solaris 11.2 guest domains ldg1 and ldg4. The guest domains ldg1 and ldg4 host applications in native Solaris zones and kernel zones.
The Oracle Solaris 10 system Sol10_sys1 is migrated onto the solaris10 brand zone Sol10_zone hosted on the Oracle Solaris 11.2 OS.
The Solaris 8 system Sol8_sys1 runs on an Oracle Solaris 10 guest domain.
Two Solaris 8 systems, Sol8_sys2 and Sol8_sys3, are migrated onto the solaris8 zones in an Oracle Solaris 10 guest domain.
