DR on a Dime for Oracle CCB - No Audio.

1. Low Cost DR implementation for CC&B DR on a DIME By Srinivasan Ramamoorthy Date: Apr 2011

3. To ensure Zero Data Loss when disaster strikes

4. Finally – low cost

5. Objective – To ensure Business as Usual at all times.Requirement © 2011 Srinivasan R 2

7. Capitalize on Server Virtualization

8. Take advantage of built-in features of Microsoft Windows 2008 R2

9. Hyper-V

10. iSCSI Initiator

11. MS Cluster Service

12. Cluster Shared VolumesThe Approach © 2011 Srinivasan R 3

14. The Oracle CC&B on Windows NLB (Apps & Web Server)

15. Servers- IBM x3650 - Intel Xeon Quad Core 4 GB RAM , 3 x 73 GB RAID 5

16. DB Servers run on Windows Enterprise Edition

17. SAN – IBM DS 4300 – DB Volume 6x300GB RAID5+1Existing setup Database Cluster Application Server (NLB) DB Server 1 DB Server 2 CCB Server 1 CCB Server 2 SAN GB Network Switches © 2011 Srinivasan R 4

19. Secondary= Backup Site

20. @Primary Site

21. Hyper-V Server 1 – IBM x3650 with 3 NICs

22. Hyper V Server 2– IBM x3650 with 3 NICs

23. SAN Server– IBM x3650 with 2 NICs (or Storage Server)

24. A dedicated GBIC switch or a dedicated VLAN required for iSCSI

25. Create Cluster using both Hyper V Servers.

26. Enable MPIO feature

27. Install iSCSI software based SAN e.g. StarWind

28. @ Secondary Site

29. DR Server– IBM x3650

30. SAN Box– IBM DS 4300

31. The Servers were upgraded as follows

32. - All servers RAM upgraded to 16GB

33. - SAN Server Hard Disks upgraded to 6 x 500 GB 15K SATA (SAS can be used)New Setup © 2011 Srinivasan R 5 Existing Servers are rearranged as

35. Use Failover Cluster Manager (FCM) to add the SAN Volume as a CSV.

36. Use FCM to add a new service and choose Virtual Machine Service.

37. Use Hyper V Manager to create new VMs – point to CCB & DB VHDs.

38. Enable the earlier configured VMs as a Cluster Service.

39. iSCSI network must use GBIC for better performance.© 2011 Srinivasan R 6

41. Configure new VM on DR Server and point to the replicated VHDs on the SAN.

42. When disaster strikes start the VM and point the clients to the new DR ServerDR Server Conventional SAN © 2011 Srinivasan R 7

43. Keeping in mind that better solutions exists, the objective of this presentation is to exhibit a concept that is affordable. Without purchasing any expensive hardware or duplicating a SAN box the objective of a DR site was met using the existing hardware with minor upgrades using the concept of iSCSI. The Solution also assumes that certain common elements such as high-speed LAN / WAN are available.
