Abstract

Methods and apparatus for configuring disaster tolerant clusters of hypervisors as a virtualized service. In an exemplary embodiment, a system discovers WWPNs components, identifies networks zones in SANs having connectivity with at least one of the storage arrays and at least one of the journaling appliances, and creates a disaster recovery service offerings including replication in accordance with the selected service offering.

Claims

1. A method, comprising:

discovering, using a processor, WWPNs for storage arrays in a system by reading an interface of the storage arrays;

discovering WWPNs of ports of the discovered storage arrays;

discovering WWPNs of journaling appliances;

discovering WWPNs of splitters seen by the journaling appliances;

discovering paths for the splitters;

discovering network adaptor addresses for the paths;

identifying networks zones in SANs having connectivity with at least one of the storage arrays and at least one of the journaling appliances;

determining ones of the storage arrays logged in and zoned in the SANs;

determining WWPNs of the storage arrays logged in and zoned in the SANs;

determining WWPN zoning of the storage arrays;

identify adaptors for storage arrays zoned and logged in;

determining ones of the storage arrays and ones of the journaling appliances zoned together for correlating replication networks host;

determining ones of the storage arrays seen the journaling appliances for correlating ones of the splitters;

identifying disaster recovery pools;

creating a disaster recovery policy;

creating disaster recovery service offerings, the service offerings including geographically separated primary and secondary storage;

receiving a user selection of a disaster recovering service offering;

assigning hosts to the selected service offering;

creating a hypervisor at primary and secondary infrastructure for the selected service offering;

creating a volume at the primary and secondary infrastructure for the selected service offering;

mapping and masking volumes to the journaling appliance and the hypervisor for the selected service offering; and

enabling replication in accordance with the selected service offering.

2. The method according to claim 1, further including applying disaster recovery policy settings to the service.

3. The method according to claim 1, further including determining an ability to connect volumes from a first pod to a second pod.

4. The method according to claim 1, further including discovering configuration information for the splitters including adaptor ports of a storage array on which a first one of the splitters is running.

5. The method according to claim 4, further including using the splitter configuration information to associate replication networks to the storage arrays and to build disaster recovery pools.

6. The method according to claim 1, further including determining a list of paths for the splitters and a list of network adapter addresses for the paths.

7. The method according to claim 1, further including correlating the storage arrays to replication networks via a storage area network.

8. The method according to claim 1, further including correlating the journaling appliances via the storage area networks.

9. The method according to claim 1, further including deleting the selected service.

13. The article according to claim 1, further including instructions for discovering configuration information for the splitters including adaptor ports of a storage array on which a first one of the splitters is running.

14. The article according to claim 13, further including instructions for using the splitter configuration information to associate replication networks to the storage arrays and to build disaster recovery pools.

15. The article according to claim 13, further including instructions for determining a list of paths for the splitters and a list of network adapter addresses for the paths.

16. The article according to claim 13, further including instructions for correlating the storage arrays to replication networks via a storage area network.

17. The article according to claim 13, further including instructions for correlating the journaling appliances via the storage area networks.

10. An article, comprising

a computer readable medium containing stored non-transitory instructions that enable a machine to perform:

discovering WWPNs for storage arrays in a system by reading an interface of the storage arrays;

discovering WWPNs of ports of the discovered storage arrays;
