2.7 Management and support tools
The IBM Flex System V7000 Storage Node system can be managed through the IBM Flex
System Management Node (FSM), or by using the native management software that runs in
the hardware itself.
System Management Node (FSM), or by using the native management software that runs in

The FSM simplifies storage management in the following ways:
Centralizes the management of storage network resources with IBM storage
