Generally you want enough memory on both nodes to satisfy the requirements
of each instance in the event of a failover. Each node can only access
databases that are in the resources for that node. Resources do not span
nodes. They share the same storage facilities but not the same drives. Have
a look at these:
Hello,
I Have some questions as regards the cluster of the SQL Server
active/active.
- Which I calculate of memory for the environment to it?
- The two virtual nodes will access to same data base?
- The two nodes will be accessing the same storage shared?
Thanks!
