Network Timeouts
System timeouts that cause interruptions in data flow can have a significant negative
affect on data traffic flow in the SAN. Ensuring that timeout parameters, such as the
530F health timeout value, are set correctly might provide better throughput.
530F SAN Appliance
When the 530F is configured in an Internet Protocol (IP) mirror network using the
asynchronous transfer mode (ATM) protocol, the IP mirror link may intermittently go
down due to timeouts. The timeout causes a break in the asynchronous data transfer
between 530F systems. To correct these timeouts, set the timeout parameter in the
530F SAN appliance software for the host, secondary, and remote systems to a
health timeout value of 6. This extended timeout value provides these systems with
additional tolerance for intermittent breaks in the IP mirror link without interrupting the
asynchronous data transfer between systems. For detailed instructions on setting the
health timeout value, see the

530F SAN Appliance Software
