SAN Transport on VMware VSAN

Hello

NetBackup supports VSAN but I'm not sure if it will support actual SAN Transport in the backup method. Having said that, the Infobits video is a bit misleading in the sense that it depicts the VSAN as being contained on what seems to be an external or SAN disk.

I'm not saying that such a configuration is not possible but the idea behing VSAN is providing a VIRTUAL SAN that is made up of internal storage from multiple ESXi Hosts. An important component of VSAN is the VmKernel Network that would distribute the reads/writes between hosts that contain copies/pieces of the data. VSAN makes sure to have multiple copies of the data so that it can tolerate one or more host failures.

So if we look at the video again, configuring VSAN on SAN that is shared between the hosts doesn't really align with the concept as all of the hosts have access to the SAN so why would you need VSAN? I suppose there might be some use case but I can't think of one now.

So back to your question. If you've configured VSAN as shown in the video then I suppose SAN transport might work if you give access to the luns as one would in non-VSAN configuration (not really sure about this one). But if you've got a VSAN configured in the traditional sense, the disks would all be contained in the ESXi hosts, so there is no way that NetBackup can access them via SAN transport, as there really is no SAN.

Does that make sense?
