If your company still lacks a viable disaster recovery (DR) strategy, it might be time to start thinking virtualization. The initial drivers behind server virtualization adoption have been improving resource utilization and lowering costs through consolidation, but next-wave adopters have realized that virtualization can also improve availability. Virtualization turns physical devices into sets of resource pools that are independent of the physical asset they run on. With server virtualization, decoupling operating systems, applications and data from specific physical assets eliminates the economic and operational issues of infrastructure silos -- one of the key ingredients to affordable disaster recovery. Storage virtualization takes those very same benefits and extends them from servers to the underlying storage domain, bringing IT organizations one step closer to the ideal of a virtualized IT ...
