SteelEye™LifeKeeper® for SQL Server is a scalable solution for eliminating SQL Server downtime from either planned or unplanned outages. With integrated data replication, high availability clustering and disaster recovery capabilities, LifeKeeper for SQL Server addresses all levels of uptime requirements, from local SQL database replication, to local application failover, to complete disaster recovery of SQL Server at a remote site.
LifeKeeper constantly monitors the health of all pieces in the SQL Server environment including servers, network connections, data volumes and SQL Server processes. On detection of any problem, LifeKeeper initiates a recovery action. This configurable action can include attempting to restart SQL Server on the same server (a local recovery), migrating the SQL Server instance to a backup server (a failover), or sending an alert to the SQL Server administrator so that the problem can be investigated. Through LifeKeeper’s intuitive GUI, administrators can manually move SQL Server instances among nodes to eliminate the need for planned downtime due to maintenance.
LifeKeeper for SQL Server does not require that you use high-end versions of either Windows or SQL Server. There is also no requirement that all servers in the cluster be identically configured. LifeKeeper is flexible so that you can deploy the HA cluster topology that makes the most sense for your business. This flexibility extends to the use of storage as well. With LifeKeeper, you can build a shared-nothing cluster using LifeKeeper Data Replication, or you can deploy a shared-storage cluster using direct attached SCSI or Fibre Channel devices.
LifeKeeper for SQL Server can also be extended across a WAN connection for full disaster recovery protection.
