SATA and SCSI
The host adapter is assigned SCSI ID 7, which has the highest priority over all other devices.

RAID and SCSI are completely different things.RAID = Redundant Array of Independent Disks.SCSI = Small Computer System Interface.SCSI is the type of interface that exists on the physical hard drive for connecting it to a host device. The host, be it a computer or a RAID would need to also support the SCSI interface.RAID is a cluster of hard drives which work together as a storage system. RAID could use any type of interface, including SCSI.
The expansion card called the host adapter is responsible for managing all devices on the SCSI bus. SCSI is a peer to peer interface
Wide SCSI bus can support up to 16 devices using channels 0-15.

The UMAX Astra 4100 scanner typically uses a SCSI interface for connectivity, so you would need a SCSI to USB adapter if you're connecting it to a modern computer that lacks a SCSI port. Ensure the adapter supports the SCSI standards compatible with the scanner. Additionally, check for power requirements, as some SCSI devices may need an external power source. Always verify compatibility with your operating system before purchasing.
Host Adapter
Depends on what the SCSI is. Ultra? Ultra Wide? Ultra Wide 2? many different types.
