Dnac in cluster

[Ciro G Mele]

I am about to configure a dna cluster ( 3 DN2‑HW‑APL 44 cores ) in the next few days together with ise. Any information about this configuration will be welcome.

Thanks a lot

Hello,

I would refer you to the High Availability guide for 2.3.3 if that's the version you have.

For integration with ISE, please refer to the Administration guide.

There's also an overview video from one of our TMEs.

Hope that helps.

Regards.

Hi PabMar,

Thank you very much for your answer. I have a question for you. Can you implement a cluster with these 3 devices 3 DN2‑HW‑APL 44 cores ? It is the smallest in the dna family.

Thanks a lot !

Hi Ciro,

From the HA guide I had linked you'll see a section that says:

What the 44 core appliance allows you to do is mix DN1 and DN2 appliances.

Hi PabMar,

This is what I read, but I don't have any dn1, that's why my question is, they are all dn2 with 44 cores, so the cluster can be made without problems, is that so? Thanks again for your time.

Hi again PabMar

If it serves as additional information, these are the 3 dna to configure in a cluster.

Thanks.

Hi Ciro,

Yes either all 3-nodes in the cluster are DN2, or all 3 are DN1 or mix of DN1 & DN2.

The screenshot you've provided are the 3 sizes available for DNA Center. Again, per the HA guide I've shared, a cluster can only be formed with the same size appliances.

Hi PabMar

For that reason I select it in red at the 3 dna that we are going to use.

Thanks again.
