High Availability

Rest Easy with nResiliency

First to deliver continuous database availability through simultaneous multi-node failure

ClustrixDB is designed to run your business-critical production applications, with our customers achieving five-9s of availability.

Within a cluster, we keep multiple consistent mirrors of each slice of your data. You get automated recovery in the face of disk or node failure and your database stays available with no data loss. This capability is significantly more robust than local master-slave configurations, where slaves can lag.

ClustrixDB’s new nResiliency feature further ensures that the database, and hence the application, remains available in the event of multiple simultaneous server or instance failures. nResliency is the first in the market to offer complete confidence that your valuable data is safe and continuously available should two or even more servers (nodes) fail at the same time. Our customers can now decide on the maximum number of nodes that could potentially fail in the cluster without losing any data, then ClustrixDB automatically generates the number of data replicas necessary to successfully recover, in the event of multi-node failure.

Configurable to the specific needs of the company and its data

ClustrixDB’s new nResiliency feature provides the ability to define the number of servers in the cluster that can become unavailable simultaneously while ensuring continuous database availability. It is easily configurable according to data sensitivity and criticality. For example, users may:

  • Set MAX_FAILURES at a high number for their high-value data that are necessary to keep mission-critical applications running in the event of simultaneous failures
  • Set MAX_FAILURES at a mid-range number for high volume data that are not required to have multiple levels of redundancy
  • Set MAX_FAILURES at a low number for high-throughput, ‘fast-lane’ data which can be easily replaced

You can also deploy another cluster across geographies with asynchronous replication. Clustrix uses the MySQL replication protocol. For disaster recovery Clustrix offers fast parallel backup that takes the same time irrespective of the number of nodes in the database cluster.
