As we mentioned in the basic section above, there are three predominate types of internal SCSI connectors. IDC 50 connectors are typically female on a cable, and male on a device hard disk, controller card, etc. HPDB 68 connectors are male on the cables, and female on the device.

They have an 80 pin connection that contains both the pins for SCSI data transfer and the pins to power the device. They're quite useful in high-availability systems where you might want to replace a damaged hard disk while the system is still running. SCA drives are usually enclosed in special trays for mounting the disk.

The speed of your SCSI chain does not necessarily reflect the speed of your devices. The fastest that most modern drives can pump out data is 40 Mbps. Why, then, would you need to have a bus that can transfer Mbps? An Ultra bus can support up to 16 devices.

You would have to pull data off of eight of them at full speed to max out the bus. For those of you that were counting, that's over T-1 lines. Stick that in your Denial of Service attack! They're in a league of their own and don't really belong here, but one thing should be said. SCSI is not just some distant creature only to be tackled when you're out of options.

SCSI Small Computer Systems Interface is a smart bus, controlled with a microprocessor, that allows you to add up to 15 peripheral devices to the computer. These devices can include hard drives, scanners, printers, and other peripherals.

High-end single SCSI boards have two controllers and support up to 30 peripherals on a single expansion card. An advantage of SCSI is that you can connect several peripherals to one host adapter, using only one slot in the bus. SCSI is widely used in workstations, servers, and mainframes; it is less commonly used in desktop PCs. If one drive fails, it can be removed and a new one inserted, without loss of data, while the system is still operational.

This feature of RAID hardware is called hot-swapping.
