An HPE Shadowbase active/active system architecture provides disaster tolerance by maintaining a network of independent processing nodes, each having access to a common replicated database. This architecture eliminates the uncertainty and cost that exists with an active/backup...
Business continuity encompasses those activities that an enterprise performs to maintain consistency and recoverability of its operations and services. The availability of application services provided by an enterprise’s IT infrastructure is only one of many facets of...
A big data analytics system typically requires a large network of tens, hundreds, or even thousands of heterogeneous, purpose-built servers, each performing its own portion of the task. All of these systems must intercommunicate with each other in real-time, and integrate with...
Continuous availability of online service necessitates the minimization or elimination of planned downtime, such as for an operating system or hardware upgrade, or for installing a new application version. This requirement...

The Connection, by Keith B. Evans
Perceptions remain that the use of TMF is superfluous, costly, or has bad performance issues, as well as a lack of understanding or disregard for the data integrity protection benefits offered by TMF. Debunking these myths...
Shadowbase synchronous replication (Shadowbase Zero Data Loss, or Shadowbase ZDL) resolves two key issues of asynchronous replication: data loss on source system failure and data collisions when running an active/active environment. By eliminating data loss...
Keeping up with user demand and managing a service outage or brownout is a significant challenge for IT departments. The traditional scale-up approach suffers from significant limitations and cost issues that prevent it from satisfying the ever-increasing workloads of a 24×7 online society...
Extended outages happen, and when they do, the cost to your business can be severe. You are at risk if you: have no business continuity plans, are using tape or virtual tape backup for disaster recovery, or have an active/passive disaster recovery plan, which may encounter failover faults...
