Greetings,
Scenario:
We have a v880 with expansion FCAL backplane and additional FCAL
controller (qlc). We wish to mirror the original set of disks on the
original backplane to the new set of disks on the expansion backplane.
I'm handy with SVM, but having MPxIO in the mix seems to add a layer
of complexity (and fault tolerance) I wasn't prepared for.
Questions:
Is this a reasonable way to increase storage fault tolerance?
Should I use MPxIO or SVM or both?
If we go with SVM alone, is it OK to have just a 2 way mirror on
all volumes?
How is it done? :) Pointers to best practice docs / recipes
would be greatly appreciated.
If I need to scrap this plan completely and start anew, please
feel welcome to say so.
thanks, will summarize.
Jacob Ritorto
