HP-UX 11i v3: The operating system of the mission-critical HP Converged Infrastructure HP-UX 11i v3 is designed to simplify and unify IT, and deliver the always-on resiliency, dynamic optimization of resources, and investment protection and stability demanded in mission-critical computing. It integrates proven UNIX® functionality with advances in high availability, security, partitioning, infrastructure and workload management, and instant-capacity-on-demand.

Overview HP-UX Containers provide multiple container types used to create an isolated operating environment within a single instance of the HP-UX 11i v3 operating system. HP-UX Containers allows the enterprise to host varied application workloads in secure individual operating environments on a single physical server, thereby better utilizing server resources (CPU, memory, and network access) and data center resources (power, cooling, and space).

Figure 2: HP-UX Containers and the Virtualization Continuum for HP-UX HP-UX Containers is a component of the Virtualization Continuum for HP-UX and is compatible with HP-UX nPartitions, HP-UX vPar, and Integrity Virtual Machine (VM) solutions. You can create containers in any HP-UX OS image; the OS image can exist in an nPartition, vPar, Integrity VM, or directly on non-partitioned server hardware.

Container types HP-UX Containers provides multiple container types. Each container type offers unique features, which allow administrators to choose the container that best fits their workload requirements. The next section gives a brief overview of each container type. For more information on system and workload containers, visit: http://www.hp.com/go/virtualization-manuals. For more information on HP 9000 containers, see the HP 9000 Containers Administrator’s Guide at: http://www.hp.

Figure 3: System container file system layout Workload containers Workload containers provide a lightweight workload hosting environment. All workload containers share their file system view, hostname, IPC namespace, and service daemons with the global. A workload container has restricted access and view of these resources, rather than a virtualized view. This restricted view of a workload container can be customized to meet the workload’s requirements.

Figure 4: Workload container file system layout HP 9000 containers HP 9000 containers replicate an HP 9000 HP-UX ecosystem and create a chroot isolated virtual HP 9000 file system. An HP 9000 container provides an environment to re-host the complete HP 9000 user-space environment without the need to recompile or re-install individual applications or reconstruct application ecosystem, all with minimal reconfiguration and application inventory preparation effort.

Figure 5: HP 9000 container file system layout Choosing the right container HP-UX Containers provide multiple container types to meet the workload hosting needs of your environment. In many situations more than one container type may be utilized to meet your needs. In order to select the best container type for the workload, you will need to compare the application deployment, administrative, high availability, and compliance characteristics of the container types with those of your workload.

When to use an HP 9000 container HP 9000 containers are ARIES-based PA-RISC execution environments. The applications under transition consideration must be suitable for ARIES emulation. For example, only user space applications are supported. If any application depends on kernel modules or specific device drivers, it will not work correctly under the ARIES and HP 9000 Containers environment. For more information, refer to the ARIES binary compatibility and product support statement.

When to use a system container System containers provide a look and feel of a standalone system and many of the capabilities of a virtual machine guest without the associated management and performance overhead. System containers allow you to migrate more of the workload’s operating environment, minimizing the process and administrative changes required. When users log into a system container, they have private versions of many of the system services that they have in a standalone operating system.
