XCC standalone (no XMC), adoption license violation?

[tfsnetman]

Hello,

• There seems to be a discrepancy between the recommended SW version for XMC and XCC and only the later version of XCC is supporting the AP410C for instance.

1. This being the case, I am wondering whether I could run XCC as as standalone VM, outside of XMC.

• Let’s say I am running 2 x XCCs with a 100 device adoption license on each, covering 200 APs.

1. What would happen if one XCC is going down and the other one has to adopt 200 APs but is only licensed for 100 APs?
2. Can I exceed the licenses for short amount of time until the dead XCC is back online?

Thank you,

Klaus

Hi Klaus,

You can run XCC as a standalone VM outside of XMC, it can be deployed as a controller on its own. 

XCC supports two modes of High-Availability (HA) configuration; Active-Active and Active-Passive.

For Active-Active

XCC will (automatically) load balance HOME assignment across both appliances (~50/50 split). It will allow up to maximum capacity of the pair. Assignment is performed on a first-come-first serve basis. The goal is to maintain an AP assignment close to 50/50. 

Example: if you have a pair of E2120s to cover 4000 APs (max HA capacity), 2000 APs will be registered to one appliance as PRIMARY and the  2000 APs will be assigned to the Peer.

In case of Fail-over (Appliance down) the 2000 APs from that instance will  automatically transition to the peer. Peer appliance will host all 4000 APs during failover time.

For Active-Passive:

XCC will assign all  adopted APs to the Primary (Home)  appliance. That assignment is done in a 100:0 ratio covering the for the entire capacity of the pair  (double capacity of a single instance).

Example: if you have a pair of E2120s at 2000 APs each, all 4000 would be declared as HOME on the primary appliance.
