Summary
By managing your Integrity VM resources with gWLM, you can ensure that their behavior aligns more
effectively with your business priorities. In addition, you can consolidate more workloads onto fewer
physical systems to make better use of your IT investments and to reduce costs while maintaining
targeted service levels. You can make all this happen easily, thanks to the simplified, web-based GUI
of the CMS, a centralized management facility integrated with HP SIM to make management of
multiple systems convenient. Through this facility, you can centrally define and manage gWLM
policies across a large number of servers and a variety of partitions with ease.
gWLM automatically adjusts resource allocation based on real-time demand, allowing for resources to
be shared when they are plentiful and to be dedicated to the highest-priority applications when
demands spike. gWLM automatically expands or shrinks the amount of processing resources
allocated to individual virtual machines as needed, and it can automatically activate or deactivate
Instant Capacity or Temporary Instant Capacity resources available to the VM Host—in either case,
you pay only for what you use. Thus, gWLM ensures that your mission-critical workloads always get
the resources they need while you get the best return on your hardware investments.
