HP PRM manages resources by partitioning a system based on PRM groups. A PRM group is a collection of processes that is assigned system resources. The system administrator assigns applications and users to PRM groups and establishes resource allocations for each group. PRM then manages each group's CPU, disk bandwidth, and memory resources according to the current configuration.
Consider using HP PRM for the following reasons:
|
- System consolidation
With HP PRM, you can run multiple, mission-critical applications on a single system.
|
- Secure Resource Partitions
HP PRM supports Secure Resource Partitions, which combine HP-UX 11i v2 security capabilities with the resource management capabilities of PRM. This combination allows you to consolidate multiple applications within a single operating system image with both dedicated resources and operating system level security from other applications.
|
- Response time
You can improve the response time for critical users and applications through effective use of PRM groups and assigned resources.
|
- Performance expectation
You can set and manage user expectations for performance through effective use of PRM groups and assigned resources.
|
- Application isolation
With processor sets and the memory isolation feature of the Memory Resource Group, you can provide your application with total resource isolation.
|
- Budget based sharing
With HP PRM, you can allocate resources on shared servers based on how much of the server each department funded.
|
- Convenient to use
You can change HP PRM configuration any time--even under load. Also, applications do not require modification to work with HP PRM.
|
- Failover recovery
You can ensure that an application package in a Serviceguard cluster has sufficient resources in a failover.
