Four FAS2050 controllers - variants of connections?

[demiendark]

E.g. I have 4 FAS2050 controllers - how can I connect them?

Is it possible to make 4-nodes cluster? or maybe Can I make 2 pair of active-active cluster

and set up between pairs an active-passive cluster?

Hi,

No 4 node cluster dosent exist, maybee in GX version, but not sure it's supported in FAS2050...

And you can do ACTIVE/PASSIV conf of tow active/active conf ...

But, the mean question is => Wath do you want to do with your FAS ?

CIFS, NFS, SAN, iSCSI ?

Explain you needs, maybee we can find solutions ...

"Standard" NetApp OS (ONTAP 7G) supports clustering of two nodes only.

They both have to be active in that sense they need to be running & both need some disks associated with them. You have the choice though to either split the disk ownership more or less evenly between two nodes (true a/a) or assign only 3 disks to one node (to keep its root volume there) & all the rest to another node (effectively a/p setup).

ONTAP GX, which does multi-node clustering, doesn't support 2000 series boxes. I am not sure whether it is going to change with the introduction of ONTAP 8, which in essence will (sort of) merge GX & G versions of ONTAP.
