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.

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

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
