4 SVA Path User’s Guide

Summary of SVA Path Benefits

• Increases potential subsystem throughput by directing I/O

through multiple host adapters and SVA channels. Logical

drives can be assigned to host bus adapters, manually

balancing the I/O load across paths.

• Provides continuous access to mission-critical data by

insulating server applications from I/O path failures.

• Installs easily and is transparent to server applications.

• Allows you to limit access to devices in a multi-initiator

(SVA) environment using LUN (logical unit number)

exclusion.
