#2. NETWORK

Here are the key requirements to send over and discuss with the network team:

1 IP dedicated by sub-net for each node

1 IP dedicated to the failover cluster

For each SQL Server Always On Availability Group (AAG) you’ll also need:

1 port number for the listener

1 endpoint port number (the default is 5022)

A share folder in which the SQL engine service account has read/write permissions (used to initialise the replication when adding a database in an Always On AG)

All ticked off? Great, let’s have a look at DNS and IP addresses next.
