Can I use a good powerful sql deployment with multi node multi instance failover cluster to host dbs for various projects (In different subnets)?
I was thinking 1 instance for each project, 1 for web server, 1 for application server, & 1 for storing transaction logs.
LUNs of each instance will be on a shared storage via SAN.
What are challenges in a setup like this? Could anyone suggest a better solution which improves performance and brings better redundancy and reduce failures and downtime.
