A minimal CloudStack deployment has one zone, one pod and one cluster running with a single shared NFS primary storage. The shared storage hosts the virtual disks for all instances running on the same cluster.

This can lead to unpredictable IO performance as instances are competing for the same shared disk resources. As load increases on the storage server, disk performance on all instances start to degrade.
