Configuring Boot from SAN

Boot from SAN

 refers to installing and booting a server’s operating system from a 

storage device attached to the SAN instead of from a locally attached storage 
device. The OS is installed on one or more LUNs in the SAN array and the FC 
adapters are configured to boot from the specified LUN. Boot from SAN providers 
several benefits including:

„

More affordable servers

„

Ease of management

„

Improved disaster tolerance

„

Improved boot LUN availability
