I have experience with FAS 3050, each has single controller. We use two such filers, and configured them as active/active HA 2-nodes cluster.
Now, as I understand, with FAS 3200 series, for instance, FAS 3250, each has 2controllers, and one filer itself can be configured as active/active.
Would you please tell me differences between these two situations and using 2 different storages, one is using two Filers, the other is using one single filer and 2 controllers?
Thanks a lot for your advice in advance!

Really not sure what the question is here but here goes:
FAS3050 clusters were shipped as 2 separate heads which together would make a cluster.
the FAS3250 can be shipped with 2 controllers in one unit I believe. There is no difference except that the 2 controllers are in the same unit which saves on space and cabling, however the downside is that there is less expandability. I believe that FAS3250 can also still be purchased as 2 separate heads, and the space where the second controller would go can host an IO expansion module.
Hope this answers you question.

As far as I understand the question it would be FAS3220 not 3250, i.e. one enclosure and 2 controllers.
