Hi all, 

We have a PBHA environment with FS7300 systems (9.1.0.x). For this, we need an IP quorum.
There is information about the IP quorum requirements: https://www.ibm.com/support/pages/ibm-storage-virtualize-ip-quorum-application-requirements-1
But I can't find any information about whether the IP quorum application is supported in a public cloud (Azure, AWS, IBM).
Is there an official statement available somewhere?

I know it was supported for IBM Spectrum Virtualize for Public Cloud

Thanks.

hi 

Yes, it is supported. public and private Cloud ...You just have to ensure the requirements for it to work correctly:

  • The maximum round-trip delay must not exceed 80ms (milliseconds), which means 40ms in each direction.
  • A minimum bandwidth of 2 megabytes per second is required for traffic between the system and the quorum application
  • Connectivity from the servers that are running an IP quorum application to the service IP addresses of all nodes or node canisters.


  • Connectivity from the servers that are running an IP quorum application to the service IP addresses of all nodes or node canisters.
