Hi all,

I need to exposs an iscsi disk to be used as a main disk in a vm. Because I am pretty new in this solution I would like to ask some tips and good practices to avoid making rookie mistakes that can really hit the performance or availability.

What are the common things I should take into account before deploying everything?

Thanks in advance

    Don’t present LUNs to VMs is the best practice. The only time you should do it is if you’re absolutely forced because you’re doing something that doesn’t support better shared disk options.

        The problem with external LUNs is that they’re out of the control of the hypervisor. You can run into situations where migration events can cause access issues. If you can have the data presented through the hypervisor it will lead to less potential issues. Using object or NFS are also good options, if available.
