Figure 7 Alternate path mode is Single mode with alternate paths in Normal and Standby

NOTE:

External arrays with Asymmetrical Active/Active (AAA) controllers, such as the Hitachi Thunder,

are an example of Figure 7. A notable characteristic of using AAA controller arrays as external

storage is that paths to alternate ports on the owning controller for a given external LU are seen

as Normal status, but I/O load balancing does not occur (either across controllers or across ports

to the owning controller). Paths to the non-owning external controller's ports are shown as Standby

status.
