Editor's Notes

  1. Lets take a look at some of these use cases in some more detail. ====================== Integrated Tiered Storage – Mix and match HDD types as you need – FC, SAS, SATA,SSD, Heterogeneous controllers, Operational Flexibility – Matching capacity/ performance needs of users to storage, on-demand re-balancing; Tech refresh with no disruption Maximized utilization - Host workloads of different throughput characteristics on a single cluster, yet tailor services to their needs Capacity/Performance Scaling Expand as you grow! – Don’t need to start with a big set up; Start w/a 2 node cluster; expand controllers and capacity when you need; non-disruptively! WRT Oracle and Exchange, this scale of the cluster is possible with Oracle and NFS or Exchange running in Vmware. Current limitations for SAN applications is four nodes. However, the technological capabilities apply equally.
