My understanding is that the requirement for separate stacks is related to the number of devices on the SAS interface, nothing to do with aggregates. Aggregates are really just a sort of volume group, so as long as the system can see the spindles then it does not matter. I'm sure there's probably some best practice documented somewhere, but the basic answer to your question is yes, aggregates can be cross-stack.</P></BODY></HTML> Tue, 20 Nov 2012 22:28:25 GMT https://community.netapp.com/t5/ONTAP-Discussions/Span-aggregates-across-stacks/m-p/15333#M3447 BEN_HOLKO 2012-11-20T22:28:25Z Re: Span aggregates across stacks https://community.netapp.com/t5/ONTAP-Discussions/Span-aggregates-across-stacks/m-p/15341#M3448 <HTML><HEAD></HEAD><BODY><P>thanks for this.</P><P>with metro cluster are the aggrs mirrored between shelfs within separate stacks, do you know?</P></BODY></HTML> Wed, 21 Nov 2012 10:25:12 GMT https://community.netapp.com/t5/ONTAP-Discussions/Span-aggregates-across-stacks/m-p/15341#M3448 nsitps1976 2012-11-21T10:25:12Z Re: Span aggregates across stacks https://community.netapp.com/t5/ONTAP-Discussions/Span-aggregates-across-stacks/m-p/15343#M3449 <HTML><HEAD></HEAD><BODY><P>This is up to you (or whoever configured metrocluster).
