High Availability Database System

Databases are the center of today’s enterprise and web applications, storing and protecting an organization’s most valuable assets and running business-critical applications. Just minutes of downtime can often result in significant amounts of lost revenue and unsatisfied customers. Making database applications highly available is therefore a top priority for all organizations.

  • Server failure (failed CPU, bad network card)
  • I/O subsystem failure (disk failure, controller failure)
  • Software/Data corruption (application bugs, OS binary corruptions)
  • User Error (shutdown a SQL service, dropped a table)
