Hi Team,

We would like to seek clarification regarding the storage configuration for the QRadar Event Processor (EP) instances.

As per the current design, two QRadar Event Processor (EP) instances and two Event Collector (EC) instances are planned for deployment. The EP instances will be deployed on RHEL virtual machines.

Our understanding is that, after the VM deployment, a Nutanix Volume Group (VG) may need to be created and presented as shared storage to both EP VMs to support an Active-Passive configuration.

Could you please confirm whether a common/shared Nutanix Volume Group can be attached to both EP VMs for this purpose? If supported, we would appreciate your guidance on the recommended approach for configuring and presenting the shared storage to both VMs.

 

We are looking for your acknoweldgement.

Here is the information I could find related to volume groups:

Is this what you are looking for?

QRadar is new to me but if you give me some additional context, I should hopefully be able to help find the answer for you.

Yes that is one of the purposes of volume groups.

Here I'm showing how to do this for a Microsoft SQL Cluster. But for Linux it is the same ;) (only in Linux not, but you will manage that)
