HP offers the broadest choice of partitioning solutions on HP Integrity and HP 9000 server platforms. Select the combination of HP-UX 11i Partitioning Continuum technologies that best meet your business needs:
- Hard partitions (nPars) offer electrical isolation and cell board granularity, allowing you to service one partition while others are online. With HP-UX 11i v3, those hard partitions actually become Dynamic nPartitions, with the ability to dynamically add or remove a cell, without requiring system reboots for the nPars involved.
- Virtual partitions (vPars) are separate operating system instances on the same nPartition or server, with O/S, application and resource isolation. HP-UX 11i Virtual Partitions enable you to dynamically move CPU power or memory between vPars as your workload requirements change. vPars also offers single CPU core granularity.
- Integrity Virtual machines (Integrity VM) have their own separate “guest” operating system instances, on the same nPartition or server, with different: OSs, versions, applications, and users, in a fully isolated environment. HP Integrity Virtual Machines software provides shared processor (with sub-core granularity), shared I/O, and dynamic resource allocation based on demand and entitlement.
- HP-UX Secure Resource Partitions (SRP) are used to consolidate multiple applications within a single image of the HP-UX 11i operating system. This is an effective way to lower the total cost of ownership (TCO). One instance of HP-UX 11i is licensed thus reducing initial software license costs contrasted to multiple servers running multiple instances of the software. Applications running in an SRP operate as though they were running in an individual system.
- Resource partitions (created from HP Process Resource Manager) allocate resources to specific applications and users within an operating system. They offer fully dynamic application processor or sub-processor and percent memory granularity.
