USER’S GUIDE

 

Default Smart Settings

There are several default Smart Settings available on the switch. These default Smart Settings were defined by Fibre Channel storage experts to ensure the switch is optimally configured for performance and stability.

The default Smart Settings cannot be modified or deleted, but these settings can be used as templates for creating custom Smart Settings.

Note: Changing the Smart Setting of a port may affect the performance or behavior of the system. Depending on the implementation, some Smart Settings are more appropriate than others.

Initiator or Target

This Smart Setting is the default setting for all switch ports from the factory. This setting offers no change protection and all settings are set to their default values. Initiators and targets can be connected to ports that are set to this Smart Setting.

This is the recommended Smart Setting for setups with targets and initiators connected to a single switch.

Initiator with Stealth

This Smart Setting is used when connecting a host device to the port. When a port is set to this Smart Setting, change notifications are not sent from the initiator to other devices, but change notifications are received by the initiator.

This Smart Setting is appropriate for embedded storage controllers and external Host Bus Adaptors (HBAs) or servers with installed HBAs.

Target with Stealth

This Smart Setting is used when connecting embedded storage devices, like JBODs, SBODs, tape drives, or external RAID systems (JBODs, SBODs, or tape libraries). When a port is set to this Smart Setting, change notifications are sent to other devices, but change notifications are not received by the target.

Fabric Connection

This Smart Setting is used when connecting a port to a Fabric switch. Only one connection from the InSpeed™ SAN Storage Switch Model 355 to a Fabric switch is valid.

Tree Cascade

This Smart Setting is used when connecting two or more switches together in a tree configuration. Up to four tree cascades are supported between switches. See “Cascading Switches” on page 43 for additional information.

String Cascade

This Smart Setting is used when connecting two or more switches together in a string configuration. Up to four string cascades are supported between two switches. See “Cascading Switches” on page 43 for additional information.

Before selecting a cascade option, consider the following:

•Cascade ports of like number should be connected together. For example, connect port 1 of Switch A to port 1 of Switch B, connect port 2 of Switch B to port 2 of Switch C, and so on.

•Cascade port numbers must be lower than non-cascade port numbers (for example, Initiator or Target ports). Therefore, select cascade types before selecting these non-cascade types.

•A maximum of three switches may be connected using string cascades.
