That's a great question! While the current output only shows the host adapters, many different types of devices can connect to a SCSI bus. Traditionally, SCSI was popular for its robustness and performance in server environments.
Here are some common types of SCSI devices you might encounter:
- Hard Disk Drives (HDDs): One of the most common SCSI devices, particularly in older server systems, for mass storage.
- Tape Drives: Used for data backup and archiving.
- CD-ROM/DVD Drives: Optical disc drives.
- Scanners: Some high-end document scanners used SCSI interfaces.
- RAID Controllers: Dedicated hardware controllers that manage arrays of disks for performance or redundancy.
Although newer buses like SATA, SAS, and NVMe have largely replaced SCSI in many modern systems, understanding its legacy and capabilities is still valuable, especially when dealing with older hardware or virtualized environments that emulate SCSI.
