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)

Hi Team,

We have a customer environment running Nutanix AHV, and we would like to understand the supported approach for integrating external NetApp storage.

Current requirement:

  • Nutanix cluster with AHV hypervisor.
  • Customer is using NetApp storage instead of Dell SAN.
  • The workload (QRadar EP/EC VMs) will be hosted on Nutanix AHV.

Could you please clarify the following:

  1. What is the recommended method to connect NetApp storage to a Nutanix AHV cluster?
  2. Is it supported to present NetApp iSCSI LUNs directly to AHV hosts?
  3. Should the NetApp storage be attached directly to the guest VMs instead of the AHV hosts?
  4. Are there any Nutanix best practices or limitations when using external NetApp storage with AHV?
  5. For QRadar EP/EC VMs, would Nutanix Volume Groups be the preferred approach instead of external NetApp storage?

Any architecture guidance or reference documentation would be greatly appreciated.

NetApp is only a recent announcement from Nutanix with no official documentation (yet).

The target release date for netapp is this summer (in the next couple of months)

You will be able to connect this via the External Storage section of Prism central. They have made it very easy actually. 

Once it’s released, you can expect documentation to be able available. If you want to know more, you may need to engage your account manager who will be able to put you in contact with the right people to help plan this implementation.
