Database instances like Oracle (including RAC) and Microsoft SQL Server (including Failover Cluster Instances (FCI) are commonly used in conjunction with volume groups. Volume groups were designed to serve several purposes, including:Decoupling VM and storage lifecycles Snapshot and storage replication based on volume group (virtual disk) boundaries instead of VM boundaries Storage presentation for physical (bare metal) workloads Sharing storage for clustering between multiple VMs or physical servers Scaling up storage performance for applications running in a single VM or physical serverIt is this last point of scaling up performance where I’d like to focus. Nutanix makes it possible to load balance virtual
