Goals of a Combined Virtualized Environment on a SPARC T5-2 System

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.

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.
