7 Oracle Solaris Cluster For Mission Critical Clouds Oracle Solaris Cluster Best HA. Best Integration. Oracle Solaris 11 Virtual Clusters Built-in server, storage, network virtualization Multi-tenant configuration from Web to database Secure, isolated Oracle Solaris Zone clusters Application fault isolation in zone clusters Failover Zones Dedicated zone network and data resources Enterprise High Availability Instant system failure detection Orchestrated policy-based, applicationspecific failover Pre-adapted fencing and quorum for data integrity Broadest data management and networking support Cluster-level Load Balancing Optimized distribution of applications load and priority management for optimized distribution Soft and hard resource limits for flexible behavior Ultimate Disaster Recovery Business continuity across unlimited distance One-click, automated switchover One-click, automated takeover Physical and virtualized environments 7 Copyright 2011, Oracle and/or its affiliates.

8 Oracle Solaris Cluster Functions Monitors health of all cluster components: Servers, storage, network OS, virtual machines Applications Tolerates failures by exploiting hardware redundancy and software algorithms Recovers cluster infrastructure and applications in in the event of failures Enables low-impact maintenance 8 Copyright 2011, Oracle and/or its affiliates. All rights reserved.

9 High Availability Framework Membership Establishes consistent inclusion of nodes in cluster Coordinates reconfiguration Cluster Configuration Repository Provides local copy on each node Enables automatic updates Enables nodes to arbitrarily join or leave the cluster Heartbeats Monitors nodes over a private network Triggers reconfiguration when a node leaves or joins the cluster 9 Copyright 2011, Oracle and/or its affiliates. All rights reserved.

10 Preserving Data Integrity Quorum Prevents partitions (split brain, amnesia) in the cluster Protects against data corruption Uses a majority voting scheme 2 node clusters require a quorum device (an external tie-breaker) Disk Fencing Used to preserve data integrity Non cluster nodes are fenced off from updating any shared data 10 Copyright 2011, Oracle and/or its affiliates. All rights reserved.

11 Application Level Management Resource Group Manager Rich and extensible framework for plugging applications into Oracle Solaris Cluster Application is wrapped by an RGM resource, supplying methods for controlling the application: Start, Stop, Monitor, Validate (aka agent) Closely related resources placed in Resource Groups (RG) Support rich dependencies between Resources and RGs Facilitates proper startup/shutdown sequencing Dependencies can have various flavors such as strong/weak/restart Works between RG and across different cluster nodes Oracle Solaris Service Management Facility (SMF) support Standard agents provided for popular applications and DB 11 Copyright 2011, Oracle and/or its affiliates.
