408 Configuring iSCSI Optimization
How Does iSCSI Optimization Interact with Dell Compellent Arrays?
Dell PowerConnect switches support a macro that may be used to configure a 
port connected to a Dell Compellent storage array. The name of the macro is 
profile-compellent-nas. The macro takes a single argument: the 
interface identifier to which the Dell Compellent array is connected. The 
macro disables unicast storm control and sets the spanning tree configuration 
on the port to portfast. For an example of how to execute the macro, see 
"Configuring iSCSI Optimization Between Servers and a Disk Array" on 
page 416.
