(8) Addition of Node
1. Upgrade by adding nodes
By adding a new D8-3010 configuration with using extended node chasis to the existing D8-3010, it
can be upgraded to 2 nodes configuration
In this case, one set of cable between nodes (7m) [NF9120-SJ65] , Cache memory, Host Director, and
Disk Director are required.
Likewise, by adding a new D8-3010 configuration with using extended node chassis and 2 sets of the
cable [NF9120-SJ65] to the existing 2 nodes configration, it can be upgraded to 3 nodes configuration
without interrupting operation.
By adding a new D8-3010 configuration with using extended node chassis to the existing 3 nodes
configuration unit, it can be upgraded to 4 nodes configuration, without interrupting operation.
In case of units in multiple nodes, you can access to disk drives of any node of from a host
port. AccessControl can associate host ports and disk drives.
Note: The number of node is the same as the number of the DAC chassis.
