ISSUE: How to maintain data and applications available on a 24x7 basis with minimal impact stemming from planned as well as unplanned downtime events. Solution Overview:[click] Legato offers robust data replication and application management technology to support rapid recovery (on the order of minutes) of applications, data, or entire resource groups (e.g. multiple systems and applications). The outstanding architectural feature of this approach is that Legatos technology provides consistent management of application availability (includes monitoring, restart, and re-hosting), as well as data sources on a cross-platform basis (UNIX and NT). This approach greatly reduces operating and hardware costs when compared to native OS vendor cluster management implementations. [click] The clustering management technology coordinates both application and data failover, thus enabling system updates or application migration without downtime.
A central management console handles performance alerts, and provides automated responses to events occur through a sophisticated rules engine. Proof Point: Companies such as Federal Express and Aetna have implemented Legato fault resilient solutions to meet demanding SLTs while enjoying cost reduction benefits stemming from standardized operating procedures and consolidated management. SLT Discussion: [click] This solutiondramatically improves service level targets. Application and data recovery ranges from under 30 seconds to a few minutes depending on the failure mode. Exposure to data loss can be minimized with proper configuration of real-time data replication.
