Sub-capacity License Counting Scenarios Sun Microsystems Virtualization NOTE: Review this presentation in conjunction with the most current Sub-capacity licensing overview presentation

Sub-capacity Licensing Requirements Summary Customers must agree to the terms of the sub-capacity attachment Customers must use eligible IBM programs with sub-capacity part numbers Customers must use eligible virtualization technology Customers must use eligible processor technology Install IBM license metric tool when it becomes available (mid 2008) Identify processor type and number of processor cores Identify IBM software deployed on servers Calculate PVUs required based on high water mark processor capacity available Current list of eligible programs and supported virtualization and processor technologies available on Passport Advantage Please note: Customers are responsible for the installation of the upcoming IBM license metric tool and for the server it runs on. While required use of the current IBM license management tool is temporarily suspended, customers remain responsible for acquiring sufficient quantities of license authorizations to comply with the sub-capacity offering terms.

Definitions - Containers Zones: A zone is a virtual operating system abstraction that provides a protected environment in which applications run. The applications are protected from each other to provide software fault isolation. To ease the labor of managing multiple applications and their environments, they co-exist within one operating system instance, and are usually managed as one entity The global zone is the original Solaris OS instance. It has access to the physical hardware and can control all processes. It also has the authority to create and control new zones, called non-global zones, in which applications execute. Non-global zones do not run inside the global zone—they run along side it—yet the global zone can look inside non-global zones to see how they are configured, monitor, and control them. Like the other zones, this global zone is also associated with a resource pool. Solaris Containers: A zone which also uses the operating system's resource management facility is then called a container. Resource pools: A resource pool is a way to dedicate CPUs to one or more containers. CPUs are allocated to a pool when the pools are defined and can be moved by redefining the pools. Containers on resource pool: The resource pools help the dedication of CPUs to one or more Containers. Containers provide the isolation. Dedicated Container: Resources when isolated and dedicated to a single Solaris Container and its applications rather than a complete system. Default Resource Pool: is a configuration mechanism that is used to partition the resources of a host. Every host has a default pool, and all processes are initially bound to this pool. Newly created pools take their processors from the default pool, leaving less processor capacity for the default resource pool. A host can be partitioned into more than one pool. CPUs: Processing resources as seen by the Solaris OS Kernel. This is synonymous with HW threads in the processors

Definitions – Dynamic Systems Domains Dynamic System Domains: Dynamic System Domains are hardware partitioning technologies built into certain high-end SPARC hardware. They allow the administrator to create separate electrically isolated OS Domains which each run their own OS.
