Using Logical Server Management in Virtualization Manager

The Logical Servers feature in Virtualization Manager allows you to perform tasks such as the following:

Populate an enclosure.
Load balance servers by moving a running logical servers from one location to another.
Evacuate servers, for routine maintenance or in case of disaster.

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 CPU cores, CPU frequency, and amount of memory.
Storage configuration.
Logical server management supports ESX and Hyper-V virtual machine logical server storage using the Virtual Machine File System (VMFS), DAS, or SAN datastores.
Logical server management supports Virtual Connect blade logical servers using shared (SAN) storage. These logical servers require that the operating system boots only from SAN, and do not support any operating system that boots from a non-SAN disk. (A virtual machine host that is running on a Virtual Connect blade with a SAN boot disk can be managed as a Virtual Connect blade logical server.)
Before you can activate a Virtual Connect blade 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.
Network configuration. Logical server management supports selection of networks from a predefined set supported by hypervisors or Virtual Connect.




	NOTE: Creating and activating logical servers does not include: Operating system provisioning. Before you can fully utilize an activated 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. (A VM guest or Virtual Connect server blade does not need to be provisioned with an operating system before it is imported.) Information such as the IP address. This is available as an attribute of the HP SIM node, and is created and maintained independently of the logical server.
