1 EXTENDED ORACLE RAC with EMC VPLEX Metro Reduced Complexity and Improved Availability Allan Robertson Derek O Mahony EMC Solutions Group 1

2 Objectives At the end of this session, you will Understand how VPLEX Metro eliminates complexity for Extended Oracle RAC environments Appreciate how VPLEX Metro and Oracle RAC offers increased availability VPLEX Metro with RecoverPoint continuous remote replication for Oracle RAC 2

3 Agenda What is VPLEX? Oracle RAC and Redundancy Extended Oracle RAC Extended Oracle RAC on VPLEX Metro Adding Disaster Recovery Database workload and Network Latency Benefits and Conclusion Questions 3

4 EMC VPLEX Family Overview VPLEX Metro Across Data Centers synchronous distances RecoverPoint Operational and 3 rd site recovery VPLEX Local Within a data center VPLEX Geo Across Data Centers asynchronous distances Mobility. Availability. Collaboration. GeoSynchrony Operating Environment 4

6 Oracle RAC Single Site Redundant RAC Interconnect Redundant LAN Backbone Oracle RAC cluster Site A Redundant SAN Fabrics Enterprise Storage systems 6

7 Oracle RAC Multiple Sites Redundant RAC Interconnect Redundant LAN Backbone Oracle RAC cluster Site A IP WAN Site B Redundant SAN Fabrics Enterprise Storage systems Array Replication 7

8 Extended Oracle RAC Before VPLEX Site A RAC Interconnect IP WAN Site B Host Mirroring Consumes Valuable CPU Cycles Admins need to configure failure groups, path preferences and ASM mirroring functions Cross-Connect Introduces SAN Complexity Mirrored I/O paths Merged SAN Fabrics Disk Management for Voting files As storage capacity and node counts increase, all of the above need to be readministered for balanced performance and HA requirements RAC Voting Files 8

9 Extended Oracle RAC After VPLEX Site A RAC Interconnect Site B No host mirroring which saves valuable CPU cycles LAN Backbone LAN Backbone No need for Oracle DBA to configure failure groups, path preferences and ASM mirroring functions Same Virtual Volume No need to merge fabrics which reduces SAN complexity and improves fault domain isolation VPLEX Interconnect No 3 rd site voting disk administration as quorum devices reside on VPLEX As storage capacity and node counts increase, VPLEX handles path balancing, scaling storage, non-disruptive movement of data and replication workload VPLEX Witness 9

17 Why VPLEX for Extended Oracle RAC Easy to configure and manage Continuous Availability Ideal for tech refresh and data/application mobility Optimized SAN Performance and Scale All reads local (cache/disk), no host overhead 100% database and application consistency upon failure Leverage for other applications Interoperates with EMC and 3 rd Party servers/arrays 17

18 Summary and Conclusion High Availability Active/active data centers with zero RPOs and RTOs Disaster Recovery Cost-effective DR for active/active data centers with point-in-time data recovery at a third, remote site VPLEX Simplified deployment of Oracle RAC on Extended Distance Clusters 24/7 application availability Simplified high availability management Automatic failure handling & load balancing Zero downtime maintenance Protection for multiple databases or application files as a unit with consistency groups Increased infrastructure utilization VPLEX with RecoverPoint Maximize available points in time (PITs) for disaster recovery Integrated RecoverPoint splitter Continuous data protection (CDP) Continuous remote replication (CRR) Continuous local and remote replication (CLR) On-demand protection and recovery to any point in time 18
