2 * ESA in cluster

[demolab]

Hi!

If I am planning 2 ESA in cluster, do I need 2 license bundle totally (for example Advantage Bundle for 500 users for 1 ESA and Advantage Bundle for 500 users for second ESA ) ?

Thanks!

No... ESAs are licensed per user count.
You do need to buy 2 physical boxes, if you're using hardware.
If you're using VMs, you can spin up as many as you need, at whatever size you need (100/300/600) using the same license file.

Keep in mind I am not a Cisco sales guy.
IIRC, clustering is included these days.

You should only have to buy 1 500 user pack.
If you get it for virtual, you will get one license file. You deploy 1 vm, or 2 vms or 5 vms, you put the same license file on it. Hardware is a little different as you have to buy to boxes and have them provisioned. You can also buy a hardware box and then request virtual licenses so you can stand up VMs along side your hardware.



HA for ESA is all in how mail is delivered to them. You can use a load balancer, multiple MX records, point mail send connectors to all ESAs, etc.

The "clustering" feature is a poor name for "configuration replication".
