Physical to virtual migration
Migrating data from physical servers to virtual machines can be painful. Veritas InfoScale Solutions products can make painful migrations of data from physical to virtual environments easier and safer to execute.
With Veritas InfoScale Solutions, there is no need to copy any data from source to destination, but rather the administrator reassigns the same storage or a copy of the storage for a test migration, to the virtual environment. Data migration with Storage Foundation (SF), Storage Foundation HA (SFHA), or Storage Foundation Cluster File System High Availability (SFCFSHA) can be executed in a central location, migrating all storage from an array utilized by Storage Foundation managed hosts.
Physical to virtual migration (P2V) requires migrating data from a physical server to a virtualized guest. The LUNs are first physically connected to the host, and then the LUNs are mapped in KVM from the host to the guest.
Without SF, SFHA, or SFCFSHA in the host, you must identify which storage devices with mapping to the guest. Putting SF, SFHA, or SFCFSHA in the host enables quick and reliable identification of storage devices to be mapped. If you are running DMP in the host, you can map the DMP devices directly. Veritas InfoScale Solutions products add manageability and ease of use to an otherwise tedious and time-consuming process.
The physical to virtual migration use case is supported for the following Linux virtualization technologies:
Red Hat Enterprise Linux (RHEL) KVM
SUSE Linux Enterprise Server (SLES) KVM
Red Hat Enterprise Virtualization (RHEV)
