https://community.netapp.com/t5/ONTAP-Hardware/Cluster-two-FAS-2552-with-two-controllers-each/m-p/147176#M9344 <P>Hi, is it possible to jhave a switchless cluster of two FAS 2552 that have two controllers each? That means a cluster contraining 4 controllers in total.</P> <P>&nbsp;</P> <P>And what's the maximum DS 2246 shelves filled with 1.2TB SAS drives can a FAS 2552 take?</P> Fri, 15 Mar 2019 09:27:42 GMT KIngstone 2019-03-15T09:27:42Z https://community.netapp.com/t5/ONTAP-Hardware/Cluster-two-FAS-2552-with-two-controllers-each/m-p/147176#M9344 <P>Hi, is it possible to jhave a switchless cluster of two FAS 2552 that have two controllers each?

So.. if my quick math is correct,&nbsp; with 1.2TB drives you'd be maxed out at 5&nbsp; (1 internal + 4 external).&nbsp;&nbsp;</SPAN></P> <P>&nbsp;</P> <P>&nbsp;</P> Sat, 16 Mar 2019 14:47:30 GMT https://community.netapp.com/t5/ONTAP-Hardware/Cluster-two-FAS-2552-with-two-controllers-each/m-p/147190#M9345 SpindleNinja 2019-03-16T14:47:30Z
