ASA5585 fail over

[shadow]

Hi,

I need to know if is it possible to have 4 ASA 5585 and connect them as cluster one primary and other as secondary  .

Thanks

You can have 4 ASA's in a cluster, but all of them would be active. If you want Active/Standby, you can only do this with 2 ASA's.
Cluster is used to added additional throughput,connections etc. This also provides failover when on of the cluster members go down.
Active/Standby failover just provides stateful failover. Throughput and performance are what a single device can provide.
