Provisioning Disk Space for Two Node AlwaysOn Cluster

Hello,

My below question is based on Win2k12 OS and SQL2k12 or higher SQL server.

If we want to setup a two node AlwaysOn cluster, there will be one primary node and another one will be secondary node. If the primary node hosts synchronized databases size of say 1 tb, then, we need to have another volume to host the same synchronized databases on the secondary node/instance for another 1 tb disk space for a total of 2 tb right?

Just want to confirm from the SMEs out there on this.

Thanks in advance.

Victor
