In our environment, we've done a SQL consolidation project, with SQL Server 2012 R2 and Windows Server 2012 R2. We've used 3 physical server, where we've done Windows cluster. on top of windows cluster SQL cluster is running. We've configured 5 instances in the consolidate platform where instance- 1 and 2 running on host-1, instance-3 & 4 running on host 2 and Instance-5 is running on host-3.
To ensure proper resource distribution, we've already capped resources (Memory & CPU) instance wise because multiple instances are running on the same host.
We've migrated various databases from different different platform to instances. Now under a single instance we've hosted databases from different services.
Can we give capping on the databases under the same instance, where as capping is already applied in the instance level?
Please, help us. My system right now in production and i need to ensure proper resource utilization to avoid any kind of service outage. Please help. Urgent.
