Use FAS2220 as DAS?

terragenesis — Wed, 04 Jun 2025 15:24:30 GMT

Hi,

Would like to ask if this is possible?

I would like to reduce the load on my switches, that is why I am looking into this.

I am currently running both controllers in HA mode.

I am trying to add the iSCSI initatiors on the server but I am unable to detect them.

Check this one:

Or the SAN Configuration Guide:

Yes it is supported.

Cheers

Hi Syntaxerror,

Thanks going to check it out now!

edit: any idea if it will work with ontap8.1.4?

If you are using 8.1.4 7-Mode it is not supported to have a direct attached connection to a HA pair but you can use it if you only have one controller:

So I can technically have 2 controllers and run each of them with teaming to my server?
