I have analysis server installed on one node of a 2-node cluster. The cubes are on a SAN drive. What I'm wondering is if anyone else who has installed AS on clusters has had any serious performance problems? This week I have started having issues where the cluster service starts going balistic, and has twice taken down the entire SAN from development to production. Bugger. This *seems* to coincide with AS queries because if I watch the graphs in PerfMon they run parallel with each other, and both push the CPU to 100% before the server looses the plot - but I really don't see the correlation between the 2 services.
