2You Only Need One VVOL for Every Virtual Machine
3Every Storage Vendor Supports the Same Number of VVOLs
4VVOLs Make All Storage Equal
5Customers Don’t Have to Make Any Changes to Deploy VVOLs
6VVOLs Solve Performance Issues by Eliminating Noisy Neighbors
7You Only Need One Storage Container per Array
VMware has suggested that VVOL users can create just one storage container per array, but that’s hardly granular. Whatever policies (disk type, QoS, dedupe, snapshots, replication, etc.) you apply to that container may apply to all the VMs on that container. You’re going to need a VVOL implementation that can support a lot of containers.
8VVOLs Enable VM-Level Storage Management
VVOLs allow you to choose VM-level services the storage admin has already set up—the VM admin can select desired performance policies for each VM. However, it does not set or guarantee performance; it merely determines into what storage container the VM will fall.
