Datasheet on the basics of DR in a virtual world
Disaster Recovery (DR) and Data Protection have become the most critical
challenges in deploying tier-one applications on a virtual infrastructure.
Applications are managed and provisioned as virtual machines (VMs) and virtual
disks (VMDKs), but current storage-based replication and disaster recovery
technologies are still LUN and volume oriented. This approach doesn’t take full
advantage of the flexibility and mobility offered by the virtual infrastructure and
results in complex, labor-intensive setup and management.
