Introduction to the HP Virtual Server Environment

These benefits also make gWLM a suitable solution for many common types of IT environments where
fine-tuned policies and specialized resource management are not applicable.
HP-UX Workload Manager is designed to manage workloads on a single system or in a high
availability cluster. HP-UX WLM is a suitable solution for a line-of-business (LOB) consolidation in
which the LOB owns its servers but relies on an IT team to manage them. WLM also gives you the
ability to fine-tune policies to support specialized resource management needs.
HP-UX WLM is intended for installations where it is already in use. HP gWLM should be considered
for new installations as well as installations where growth, in terms of scale or complexity, are
anticipated.
