Common MIB module to manage services in Storage Area
Network (SAN).  Service is deployed on service
nodes on multiple switches forming a cluster.  
Nodes in the same cluster pick up the workload of 
a failed node to provide fault tolerance.  An example 
of service that can be deployed is 
IO Acceleration (IOA) service.
