Do you know if its possible to use a RDX device (removable harddisk cassette) as backup target in VMware? Actually I don't know how to mount Tandberg RDX cartridges into ESXi host filesystem.
Thanks in advance for any idea here.
ESXi supports NFS and iSCSI, apart from locally attached storage. So your posibilities to mount Tandberg RDX will depend on the kind of storage protocols it supports.
In case it does not support anything but attaching it locally via a driver, you would depend on that driver being available for ESXi. In case such driver does not exist for ESXi, you could attach your Tandberg device to a small PC (something like a Raspberry Pi) running some OS that your device supports, and then share that OS via NFS or iSCSI.
