Hi there,
I know this question has been asked several times and god knows i have read every post i could find about it but i am having a hard time trying to convince myself that i understand what i am trying to do. First a little background on the environment. We currently have 2 Datacenters (DC) each with a cluster of FAS8000 (Ontap 9.2) each serving different sets of data through CIFS. Datacenter A has CIFS lifs on vlan 1 and Datacenter B has CIFS lifs on vlan 2. Streching the LAN is not an issue for us. Now, our goal is to be able to create/protect SVM-CIFS-DC-A on Datacenter B and SVM-CIFS-DC-B on Datacenter A through SVM-DR. As I read the SVM-DR express guide it seems possible to replicate the SVM network configuration as well. One of our goals is also making the failover as transparent to our clients as we can, meaning we dont want have to modify clients DNS TTLs or mess arround with CNAMES in the event of a failover. We have heard of the use of loadbalancer but havent been able to find a reference architecture that makes use of them (if you have it please share it). So, in the event of a failure in DC-A's filer would not my clients that were accessing data from DC-A be able to retrive data from the protected SVM-CIFS-DC-A brought up in DC-B after i bring it up and ARP does it things and updates the new "MAC" associated with the CIFS lif brought up on Filer B which has the same IP as in DC A? What I am missing? Where do the CNAME and loadbalancer sit here. I dont even see a need for them...
Thanks in advance and sorry for the long post 🙂
