InfoScale configuration options for a KVM environment

The following table lists the configurations that InfoScale products support in a Kernel-based Virtual Machine (KVM) environment. The table also lists the minimum required InfoScale configurations to achieve the corresponding storage and availability objectives. You can mix and match the use of InfoScale components and solutions as needed to achieve the desired level of storage visibility, management, replication support using Volume Replicator (VVR), availability, and cluster failover for your KVM hosts and guest VMs.
