Good day.
We have 2-node active/passive MSSQL2012 cluster (on Win 2008 R2). One "default" instance.
We want convert to active-active, (multi-instance).
As I understand, one SQL instance (existing) will run on 1 cluster node and the second (new) instance on the 2 cluster node.
I have some questions:
- we have cluster virtual name and ip address for existing MSSQL instance, for the second MSSQL instance we need to create another name and ip ?
- for second MSSQL instance we can create 2 separate cluster disks (for DB and LOGS) ?
- for second MSSQL instance we can create another DTC instance and bind it to the second MSSQL instance ?
- we can use existing physical LAN connectors on our servers (data and heartbeat) or we need to add new LAN adaptors ?
- quorum disk is the same for all instances ?
Sorry for my bad English.
