Components Looking at IT systems several components must be considered Hardware Availability Hardware Availability is the guarantee of the availability of system's hardware Fault Tolerant Systems Fault Tolerant Systems reach by a high measure at redundancy that the loss of one building group does not lead to the impairment of the application
Infrastructure Reliability Infrastructure Reliability includes redundate communication and data connections and the protection of bad access
Logical Fault Protection Logical Fault Protection is the protection of humans caused logical mistakes StandBy Database A stand-by-database is a copy of the original database on an other system in LAN or WAN DBShadow To create and administer a stand-by-database easily Libelle offers a standard product
Application Availability Application Availability is the availability of enterprise-critical data and applications Cluster Clusters represent the connection of several servers to an uniform system and so they provide one or several applications or performances Load Balancing Cluster Load Balancing Clusters provide homogeneous applications several times for the increase of the total performance High Availability Cluster High Availability Clusters (also called Failover Clusters) are used for the protection of one or several business-critical applications SteelEye LifeKeeper SteelEye LifeKeeper is a cluster solution from the class of availability clusters to the integration of enterprise-critical applications and data into High Availability concepts Structure & Function At this point structure and function mode of the SteelEye LifeKeeper are described in detail Hierarchy At this point structure and function mode of the SteelEye LifeKeeper are described in detail
Licensing Licensing of the LifeKeeper takes place per server in the cluster independently of their equipment as for example number of processors Support Constant support of SteelEye LifeKeeper Data Access SteelEye LifeKeeper makes possible a multiplicity of different access methods on the common data
Advanced Appliance Scenarios Advanced Appliance Scenarios develop in LifeKeeper by its modular design and auxiliary components such as Data Replication
