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.
- 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.
