Configuring the EVM Network
Figure 5–1: EVM-SAN configuration with one host computer
Example 2: EVM on Multiple Host Computers
The configuration in Figure 5–2 provides for nearline storage and tape backups of
volumes on StorageWorks storage systems. EVM can also mount replicated volumes
on any of the three host computers. This configuration allows for several possible
uses.
For example, Computer 3 might be used to perform tests on copies of transaction
records produced by the application on Computer 2. Computer 4 could be a dedicated
tape backup server that backs up daily transactions from the application running on
Computer 2 and also backs up testing results from Computer 3.
