Provider
The WBEM services provider for real-time utilization data from managed systems.
VCEM Virtual Connect Enterprise Manager. A management tool for defining a server connection
profile for each server bay. This profile establishes the Media Access Control (MAC) addresses
for all Network Interface Controllers (NICs), the World Wide Names (WWNs) for all host bus
adapters (HBAs), and the SAN boot parameters. If the server blade in the server bay is replaced,
the configuration and connection profile stays constant.
virtual machine A software entity provided by HP Integrity Virtual Machines, VMware ESX, VMware ESXi, or
Microsoft Hyper-V. This technology allows a single server or nPartition (with Integrity Virtual
Machines) to act as a VM Host for multiple individual virtual machines, each running its own
instance of an operating system (referred to as a guest OS). Virtual machines are managed
systems under Insight Dynamics.
virtual partition A software partition of a server, or of a single nPartition, where each virtual partition can run
its own instance of an operating system. A virtual partition cannot span an nPartition boundary.
VM Host A server running HP Integrity Virtual Machines, VMware ESX, VMware ESXi, or Microsoft
Hyper-V that provides multiple virtual machines, each running its own instance of an operating
system.
vPars An HP software product that provides virtual partitions.
vPars monitor The program that manages the assignment of resources to virtual partitions in a vPars-enabled
system. To enable virtual partitions, the vPars monitor must be booted in place of a normal
HP-UX kernel. Each virtual partition running under the monitor then boots its own HP-UX
kernel.
WBEM Web-Based Enterprise Management. A set of web-based information services standards
developed by the Distributed Management Task Force, Inc. A WBEM provider offers access to
a resource. WBEM clients send requests to providers to get information about and access to the
registered resources.
WMI Windows Management Instrumentation. Insight Dynamics uses WMI for data collection from
managed systems running Microsoft Windows. WMI queries and responses are converted to
WBEM through the WMI Mapper.
workload The collection of processes in a stand-alone server, nPartition compartment, virtual partition
compartment, or virtual machine compartment. HP Insight Global Workload Manager software
for Integrity (gWLM) extends this concept to include processor set (PSET) compartments and
Fair-Share Scheduler (FSS) group compartments. gWLM enables you to monitor and manage
workloads by automatically adjusting the resource allocations of compartments based on policies.
