Hi,
If I got the question right - ASM will issue two write requests to separate
controllers/ports your arrays are connected to. It's same as any other
software based LVS - no tricks there. 2 mirrors 2 write requests. Starting
with 11g you can define preferred mirror for read requests if I remember
correctly.
