Controller Failover Scenarios - 5508

I am putting a design together for a resilient wireless network.

I have 2 main data center sites

Site 1 I will have either:

1 x 5508

1 x 5508 + HA

2 x 5508 in N+1 failover

 

Site 2 will have just one 5508 controller.

 

What failover models are available to me?

 

Can I have an option of N+1 with also a failover to Site 2 if Site 1 is down

From my initial research I think I can can only configure AP's to have a primary and secondary controller configured.

So think the best model is an HA pair in Site 1 and the 5508 in Site 2

What I don't understand yet is the controller to controller failover?

I will be running a guest network out of Site 1 and require the controllers there to be the anchor

Any advice is appreciated.

Thanks

You can have various designs

You can have various designs:

Option 1:

You can have AP's on both WLC's to off load traffic

Site 1:

5508 with license

Site 2:

5508 with license

Option 2:

You have AP's on one WLC and the other is backup

Site 1:

5508 with license

Site 2:

5508 HA sku

Option 3:

You run N+1

Site 1:

5508 with license

5508 HA sku N+1 (Secondary)

Site 2:

5508 HA sku N+1 (Tertiary)

Option 4:

You run AP and Client SSO

Site 1:

5508 license

5508 HA sku AP SSO

Site 2:

5508 HA sku N+1

Option 5:

Run both sites with AP SSO

Site 1:

5508 license (Primary)

5508 HA sku AP SSO

Site 2:

5508 license (Secondary)

5508 HA sku AP SSO
