Sure.

It's called a RDM when you do that. https://docs.vmware.com/en/VMware-vSphere/6.0/com.vmware.vsphere.storage.doc/GUID-9E206B41-4B2D-48F0-85A3-B8715D78E846.html

Pros/Cons... can depend why you want to do it.

migration is probably the only real "con" that stands out when I've worked with these in the past. Which isn't horrible, it's (usually) just a few extra steps.

Alternatively, you can map directly iSCSI to a VM. I've done it all the time in Windows VMs. Procedure is the same as a regular Linux iSCSI LUN.

You asked for pros and cons, what are you comparing to?

Why do you need it?

What are you using now?

This situation is OK, which has the advantages of low hardware cost, easy operation, strong scalability, etc.

The disadvantages are performance loss, network dependencies, security issues, management complexity, and risk of a single point of failure. In actual applications, you need to select a storage scheme based on specific application scenarios and requirements
