Introduced with Apple's first SCSI hard drive, the Hard Disk 20SC in September 1986, Apple HD SC Setup can update drivers and partition and initialize hard disks.
•
It was often used when reinstalling the operating system of an Apple Macintosh computer, or to repair corrupt partition information on a SCSI hard disk.
It is a serial architecture that can be used as the transport layer in a SCSI network, with up to 127 devices.
Clock skew is the reason why at fast speeds or long distances, serial interfaces (e.g. Serial Attached SCSI or USB) are preferred over parallel interfaces (e.g. parallel SCSI).
Fast Wide Single-Ended, an implementation of SCSI that uses Fast SCSI, Wide SCSI and Single-Ended electrical layout
The Newisys SA2120 SAS (Serial Attached SCSI) JBOD is a high-density SAS host to SAS/SATA disk direct attached primary or near-line storage solution.
•
Based on the SCSI extended command set and serial interface, the Newisys SA2120 delivers up to 6.0 TB of incremental storage capacity at transfer rates up to 4800MB/second aggregate bandwidth.
Original work on Serial Bus Protocol started as an attempt to adapt SCSI to IEEE Std 1394-1995 serial interface.
SCSI (Small Computer Systems Interface), pronounced Skuzzy
SCSI-160, an implementation of the SCSI (Small Computer System Interface) standards for data communication
On the back of the system, a variety of connectivity options were available such as analog audio, coaxial/XLR/toslink optical connectors for input and output, SCSI (for external hard drives or tape backup units), various sync sources (video/SMPTE/etc), MIDI, and RS-422 ports for remote controlling the Foundation 2000 from other devices, or using the it to control other devices.
Ports included SCSI, two serial ports, an ADB port, a floppy drive port, and 3.5mm stereo headphone sound output and microphone sound input sockets.
Debuting at half the price of the 950, the 800 featured the same Motorola 68040 33 MHz processor as the 950 but its additional interleaved RAM, as well as an enhanced video system and SCSI bus, enabled it to outperform the 950.
Standard features included 10baseT Ethernet, LPT connectivity, SCSI connectivity, an expansion port for other networking options, 133 MHz PowerPC CPU, and PostScript.
Both VMEbus and a BBC Micro-compatible "1MHz bus" expansion buses were provided, as was a SCSI host adapter, and an optional Ethernet interface.
The disk subsystem was either accessible from multiple nodes (using a Fibre Channel SAN or dual-ported SCSI) or used cross-node mirroring in a similar fashion to DRBD.
Outside of mainframe environment, tape drives and libraries mostly featured SCSI.
These included graphics cards (through their Paradise subsidiary, purchased 1986), core logic chipsets (by purchasing Faraday Electronics Inc. in 1987), SCSI controller chips for disk and tape devices (by purchasing ADSI in 1986), networking (WD8003, WD8013 Ethernet and WD8003S StarLAN).
