vSphere 5 and LTO via SAS

I would like to know if there is direct support for using LTO-4 Tape drives attached by SAS in VMware. We intend to use a VM for performing OS-level backups, and in addition vCenter to perform imaging. Currently a single server will host all important (vSphere) VMs to consider.

Unfortunately not, it's also not recommend to connect any tape drive to a SAS card. You should use a SCSI card only, and then use VM Direct Path I/O to present this PCI device to the VM.

This is recommended by the tape vendor and the backup vendor.

VMware does not support Tape Drives connected directly to ESXi 5.x

you can't attach a tape drive direct to the ESXi host and do backups from the ESXi OS but you can attach the tape drive to the host and mount to a VM via VMDirectPath.  Make sure your HBA is supported by the VMware HCL
