Hi,
In VMware we’re used to assign LUNs to the hosts, format as VMFS and then put VMs on them. I have a hard time finding in the docs how this works. I some mentions of assigning raw disks, but that would be a real pain with the number of VMs we have, afraid we would be hitting the max allowed LUNs per host. (Using Pure Storage)
Regards
Hello @Gabe,
Apologies for the delay and welcome to this community.
The way storage works in OpenNebula is a bit different from how VMware handles SAN LUNs and VMFS. There is support for block-level storage like FC, but it isn’t as simple as just presenting a LUN and putting VM disks on it the VMware way.
Please check the docs: DataStorage Overview.
Some of the main differences are:
- No automatic “VMFS” abstraction.
- Datastores are the main abstraction.
- VM features like snapshots and live migration depend heavily on the type of datastore used.
Hope this helps you. In any case, it will help us a bit more if you can comment a bit more about your use case, so we can propose some options.
Best regards,
