Hello everybody,
After running with 7-mode for >8 years we have to move to clustered ONTAP and we would like to do it with minimum disruption and need to re-engineer our tools/scripts.
In our current setup we have FAS8020 with dual controllers and 3 24disk shelves per controller, with identical disks. We have just one aggregate per controller, where we have root volume and data volumes (less than 10) as well. Most volumes are used for NFS3, while couple of them - with CIFS. We have 2 1G and 4 10G port per controller which we use following way: one 1G for CIFS (VLAN 10), on1 1G - for administration (VLAN 30), two 10G interfaces for NFS combined in МША with a single VLAN (VLAN 30), two remaining interfaces companed into aggregated channel (VIF) with VLANs enabled for separate VLAN access.
So my question is - how much it is possible to adapt similar design with cDOT? If my understanding is correct, cDOT requires separate root aggrage and we can host data SVMs/volumes at root aggregate. Is this correct? If not - how can I change the standard setup?
Second question - about network. While we plan to have switchless cluster, it would take 2 interfaces (1 - 1G and 1 - 10G) for cluster interconnect so interfaces available for project/administraton networks are reduced. Is this statement correct?
Finally question about SVMs and volumes. At our current setup we have the same volume accessible from different network/purposes. How can I setup the volumes/SVM the same way?
Finally - is there any document/note/report which would help me to understand differences between cDOT and 7-mode and make our transition painless?
Thanks.
