What is an EVM Network?
An EVM Network is a network that consists of EVM-enabled computers that are connected to a common LAN and to an EVM-compatible StorageWorks subsystem.
Typically, one computer, called the EVM Server, manages the EVM Network and EVM jobs, and provides the Web browser interface to users. The actual production computers that are involved in EVM jobs are called EVM Clients. The StorageWorks subsystem is the other major component of an EVM Network. It provides all of the storage units that are used in EVM jobs. For information on EVM compatible subsystems, see StorageWorks Subsystem.
In its most compact configuration, an EVM Network can consist of a single computer that is connected to a StorageWorks subsystem. The largest EVM Network can include ten computers, one EVM Server and nine EVM Clients.
Planning
To take full advantage of the power that EVM provides, you should assess your present resources and develop an EVM implementation plan. Then, use the plan to guide your installations. Setting up each EVM Network can involve installing the EVM software on up to ten computers.
Information on planning and installation can be found in the SANworks Enterprise Volume Manager Installation Guide and in the Help / User Guide topics.
