HP Systems Insight Manager 5.3 Technical Reference Guide

Appliance software provides a launch site for value-added HP storage management applications and
provides navigation links to directly manage storage components on the SAN.
• HSG Element Manager
This easy-to-use, graphical storage configuration and monitoring tool centralizes storage management
across network and multivendor platforms. HSG Element Manager reduces the job of storage
management to simple point-and-click actions across the switched Fibre Channel SAN. It provides for
easy configuration of HP StorageWorks HSG80/60 storage systems as well as field-replaceable unit
(FRU) level fault detection and notification through an SNMP agent with MIB event logging. This new
version introduces a provider for the Storage Networking Industry Association Storage Management
Initiative Specification (SMI-S), enabling greater multivendor manageability in the enterprise network
storage infrastructure.
HP OpenView Storage Management Appliance is available through HP SIM from the Tools & Links tab
on the System Page. See “Tools & Links tab” for information about accessing the System Page.

HP Process Resource Manager overview
HP Process Resource Manager (PRM) enables you to focus the appropriate amount of system resources
exactly where you need them. This powerful resource management tool runs as in addition to HP-UX. When
PRM is enabled, groups of users or applications are guaranteed a specified portion of the total system CPU
processing cycles, of the available real memory resources, and of the disk bandwidth to logical
volume-managed (LVM) systems.
PRM is a resource management tool used to control the amount of resources that processes use during peak
system load (at 100% CPU, 100% memory, or 100% disk bandwidth utilization). PRM can guarantee a
minimum allocation of system resources available to a group of processes through the use of PRM groups.
A PRM group is a collection of users and applications that are joined together and assigned certain amounts
of CPU, memory, and disk bandwidth. There are two types of PRM groups:
• FSS PRM groups An FSS PRM group is a traditional PRM group, whose CPU entitlement is specified
in shares. This group uses the Fair Share Scheduler (FSS) in the HP-UX kernel within the system's default
processor set (PSET).
• PSET PRM groups A PSET PRM group is a PRM group whose CPU entitlement is specified by assigning
it a subset of the system's processors (PSET). Processes in a PSET have equal access to CPU cycles on
their assigned CPUs through the HP-UX standard scheduler.
Reasons to use PRM
• Improve the response time for critical users and applications.
• Set and manage user expectations for performance.
• Allocate shared servers based on budgeting.
• Ensure that an application package in a Serviceguard cluster has sufficient resources on an active
standby system in the event of a failover.
• Ensure that critical users or applications have sufficient CPU, memory, and disk bandwidth resources.
Users who at times run critical applications might at other times engage in relatively trivial tasks. These
trivial tasks can compete in the users' PRM group with critical applications for available CPU and real
memory. For this reason, it is often useful to separate applications into different PRM groups or create
alternate groups for a user. You can assign a critical application its own PRM group to ensure that the
application gets the needed share of resources.
• Restrict the CPU, real memory, and disk bandwidth resources available to relatively low-priority users
and applications during times of heavy demand.
For example, mail readers can consume significant disk bandwidth when users first come into work or
return from lunch. Therefore, you might want to assign a mail application to a PRM group with small
