Fabric Watch Overview and Information

Fabric Watch software monitors the performance and status of StorageWorks SAN switches,
and can alert storage area network (SAN) managers when problems arise. The real-time alerts
from Fabric Watch software help SAN managers solve problems before they become costly
failures. SAN managers can configure Fabric Watch software to monitor any of the following:
• Fabric events (such as topology reconfigurations and zone changes)
• Physical switch conditions (such as fans, power supplies, and temperature)
• Port behavior (such as state changes, errors, and performance)
• SFPs (for switches equipped with SMART SFPs)
Fabric Watch is documented in the HP StorageWorks Fabric Watch Version 3.0.x/4.0.x User
Guide. Fabric Watch default settings can be found at the following HP website:

Refer to the HP StorageWorks Fabric Watch Version 3.0.x/4.0.x User Guide for more
information.
Fabric Watch Daemon
During switch startup or reboot, the Fabric Watch daemon is one of the last processes to
become active. Depending on the size of the fabric, Fabric Watch may take several minutes to
complete its start up sequence. Before Fabric Watch is completely active, it cannot monitor
events occurring in the fabric. During this time, the switchstatuspolicyshow
command shows the default settings instead of any custom settings.

ISL Trunking Overview and Requirements

Interswitch Link (ISL) Trunking is an optionally licensed product available on the
StorageWorks 2 Gb SAN switches running Fabric OS V3.0.x, and the StorageWorks SAN
switches and StorageWorks Core switches running Fabric OS V4.0.x. ISL Trunking is
managed using telnet commands or the Advanced Web Tools interface. ISL Trunking
simplifies network design and reduces the cost of storage management by optimizing
bandwidth use and enabling load sharing of traffic at the frame-level.
