Virtualization Manager starts with the Visualization tab selected. By default, this view shows the VSE resources on the
systems within the currently-selected collection that are properly
licensed and that you are authorized to view, along with real-time
utilization metrics (CPU, Memory, Network, Disk, and Power). Systems
are displayed in hierarchical compartments (for example, nPartitions
inside a complex, virtual machines inside a VM Host, server blades
inside a BladeSystem enclosure). The hierarchical display can be expanded
and collapsed using the ![[+]](img/tree_open.gif) and ![[-]](img/tree_close.gif) icons.
To include workloads within the displayed hierarchy, select the Show Workloads check box. Additional icons in the compartments provide quick navigation
to management tools or provide more detailed information in a pop-up
window. Hover over any icon or control to see quick information about
its function. For detailed help, click the ![[?]](img/help_button.png) button. Using the Perspective control, you can
change from the default perspective to any of the following: Physical and Virtual (default perspective)
To view workload details, select the Workload tab. To use HP Global Workload Manager (gWLM) to view
and manage SRDs, select the Shared Resource Domain tab. To use HP Capacity Advisor,
select the Capacity Advisor tab. For more information about Virtualization Manager, see the HP Virtualization Manager Version 4.0 Getting Started Guide. A logical server is a set of configuration
information that you create, activate, and move across physical and
virtual machines. It contains the logical server definition and description,
including the server compute resources (for example, number of processors
and amount of memory), and the server connections to networks and
storage fabrics. A logical server is managed within Virtualization Manager and,
when activated, is applied to the creation of a virtual machine using
hypervisor-based software or to a bare-metal server blade using HP
Virtual Connect technology. Logical servers can be defined using
the Create Logical Server wizard, or created and activated via the
import of an existing server blade or virtual machine. The Logical Servers feature in Virtualization Manager allows
you to perform tasks such as the following: Populate an enclosure Use Create Logical Server, Import Logical Server, and Move Logical Server. Load balance servers Use Move Logical Server to move running logical servers from
one location to another. Evacuate servers, in case of disaster Use Move Logical Server.
Using logical servers within the Virtualization Manager provides
the following benefits: Allows you to use a common interface and management
tools for both virtual machines and server blades. Allows you to deploy resources only when needed. For
example, some applications are needed only during parts of a business
cycle. Increases business agility and flexibility by decoupling
business processing from physical hardware, allowing you to respond
to rapid changes in demand. Reduces downtime required for physical system maintenance,
whether planned or unplanned. Allows for server consolidation and improved server
utilization, which help to maximize limited compute resources.
Each logical server that you create, or define,
includes the following information: Identity information,
including a unique name, description, platform type, architecture,
and operating system on which the logical server is to be created. Compute resources, including number of CPUs, CPU frequency,
and amount of memory. Storage configuration. Before you can activate
a logical server, you must obtain storage world wide names and LUN
IDs from a storage administrator. Alternatively, you can modify storage pool entries that are accessible
when you create a logical server. Storage pools allow you to access
storage without being concerned with where or how that storage is
physically located or managed. Predefined network configuration.
Creating and activating logical servers does not include: Operating system provisioning. Before you can activate
a logical server, you must install the operating system. (If the server
blade or virtual machine has been provisioned with an operating system,
activating the logical server boots it.) Information such as the IP address. This is part
of the HP SIM node’s server or system metadata, and is created
and maintained independently of the logical server.
