Introduction to Oracle^® Solaris 11 Virtual Environments

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 systems onto a single SPARC based system.

• 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 system 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:

• The Oracle Solaris 10 system sol10-sys1 is migrated onto the solaris10 brand zone sol10-zone hosted on the Oracle Solaris 11.3 OS.

• Two Oracle Solaris 11.1 systems, sol11-sys1 and sol11-sys2, run in the Oracle Solaris 11.3 guest domains ldg1 and ldg4. The guest domains ldg1 and ldg4 host applications in native Oracle Solaris zones and kernel zones.

• The Solaris 8 system sol8-sys1 runs on an Oracle Solaris 10 guest domain ldg3.

• Two Solaris 8 systems, sol8-sys2 and sol8-sys3, are migrated onto the solaris8 zones in an Oracle Solaris 10 guest domain ldg2.

The high-level tasks to perform the consolidation into virtual environments are described in the following sections.
