1 Enterprise Linux Business Continuity Solutions for Critical Applications Introducing SteelEye Protection Suite for Linux Multi-site Cluster May EMEA

2 DataKeeper Our Expanding Family of Solutions Volume block-level change-only replication provides real-time continuous data protection Operates stand-alone or integrates with HA Clustering Offsite protection of data for disaster recovery, backup consolidation, regulatory requirements LifeKeeper High-availability clustering monitors entire application environment including servers, storage, application services, database, network connections. Takes automated corrective action on any failure Supports P2P, P2V and V2V clusters Out-of-the-box protection for MySQL, PostgreSQL, Oracle, SAP Over 30 application-aware agents LifeKeeper Extender lets you protect any application

3 LifeKeeper for Linux The Gold Standard for Linux High Availability Two Primary Storage Configurations Classic Shared Storage Clusters Utilizes Fibre Channel SAN or iscsi Shared Storage Arrays, NAS devices Optimal for deployment within a single data center Multiple servers can share the same storage device SCSI reservations protocol provides I/O fencing to ensure data integrity Distance limited by shared storage protocol Shared storage device can be single point of failure

4 LifeKeeper for Linux The Gold Standard for Linux High Availability Two Primary Storage Configurations Shared Nothing Clusters using SteelEye Data Replication Block Level, Change-only replication Synchronous or Asynchronous Multiple targets in separate locations Compression and Bandwidth Throttling CDP Features Rewind and Recover Ideal for disaster recovery configurations

5 SteelEye Data Replication for Linux Built on top of optimized Linux kernel components: md and nbd SteelEye developed and contributed code into 2.6 kernel to optimize WAN replication and reduce full resync requirements Less than 3% server CPU utilization during initial sync and less than 1% during normal operations Wizard-based user interface simplifies building and management of replica mirrors SLES, RHEL, CentOS support

6 The Best of Both Worlds? What if there was a solution that provided the Robustness and Flexibility of a Shared Storage cluster and the Disaster Recovery Protection of a Replication-based cluster?

7 SteelEye Protection Suite for Linux Multi-site Cluster Combines the robustness of a classic shared storage cluster with efficient data replication to a disaster recovery site. Provides all the features of SteelEye Data Replication to protect data in LifeKeeper shared storage clusters Cascading failover across prioritized server nodes Automatic replication redirection

8 SteelEye Protection Suite for Linux Multi-site Cluster Use Case NFS Server Use Case Combines a local shared storage cluster protecting an NFS service with one or more replicated sites Production Data Center Disaster Recovery Site The primary server (P1) is backed up by a secondary server (P2) P1 P2 D1 These are both backed up by a server in the disaster recovery site (D1) NFS Shared volume (/S1) is replicated across WAN to DR site NFS Clients connect via virtual IP / S1 / S1

9 SteelEye Protection Suite for Linux Multi-site Cluster Use Case NFS Server Use Case with Primary Server Failure The shared storage resources failover from the primary server (P1) to the backup server (P2) All clients automatically redirect to server P2 Production Data Center Disaster Recovery Site P1 P2 D1 The source of the replication automatically switches from the primary (P1) to the backup (P2) / S1 / S1

10 SteelEye Protection Suite for Linux Multi-site Cluster Use Case NFS Server Use Case with Production Data Center Failure Mirrored storage is brought into service automatically All clients automatically redirect to server D1 Replication pauses until Production Site is operational, then all changes during downtime are merged into shared storage and failback can occur if desired Production Data Center P1 P2 D1 / S1 Disaster Recovery Site / S1

11 Benefits of the SteelEye Protection Suite for Linux Multi-site Cluster Leverages SteelEye s years of experience in delivering Linux high availability solutions expanded to include wide-area disaster recovery Extends existing shared storage clusters to include wide-area protection Less expensive and more flexible than storage-based replication solutions No requirement that servers, storage be identical within the cluster Application-agnostic. Any application can be protected with SteelEye solutions for the most common apps available off of the shelf.
