Next-Generation Disaster Recovery and Availability Technologies for IBM Power Systems
Source: Vision Solutions
Due to globalization, Web-based sales and service, more vigorous competition, and more stringent regulations, the goal of ensuring the availability and recoverability of data and applications has risen considerably on the priority lists of today's CIOs. A wide range of technologies is available to address this goal. At the apex of a spectrum of solutions sits a strategy that maintains highly redundant, geographically dispersed systems and data, commonly identified as High Availability (HA) or Disaster Recovery (DR). Occupying the lower extreme is traditional tape-based backups, which provide reliable but rudimentary disaster recovery capabilities. But between the two sit a variety of technologies offering various levels of system availability and recovery speed and completeness.
