Abstract
본 발명은 톨러런트 컴퓨터의 I/O인터페이스와 관련된 것으로서 이것은 특히 SCSI버스 방식을 채택하여 I/O디바이스 성능을 빠르게 하여 채널 확장을 위한 제2, 제3의 SCSI가 지원되도록 한 톨러런트 시스템에 관한 것이다.The present invention relates to an I / O interface of a tolerant computer, and more particularly, to a tolerant system in which a SCSI bus method is used to accelerate I / O device performance so that second and third SCSIs for channel expansion are supported. will be.
종래의 톨러런트 시스템은 MFB라는 시스템 버스를 사용하고 I/O디바이스와의 인터페이스를 위해 IOP와 TPI버스를 사용하고 있으나 이때의 TPI버스는 전송속도가 느리며 또 주변기기들이 바로 TPI버스에 접속될 수 없어서 별도의 콘트롤러를 연결하여야 하므로 I/O성능이 느려지게 되고 시스템 가격이 상승되는 원인이 되었다.Conventional tolerant systems use a system bus called MFB and use IOP and TPI buses to interface with I / O devices, but at this time, the TPI bus has a slow transmission rate and peripherals cannot be directly connected to the TPI bus. Connecting a separate controller slowed down I / O performance and caused the system price to rise.
이에 본 발명에서는 시스템 버스인 MFB에 SCSI인터페이스 방식이 TSHA를 연결하고 I/O버스로는 I/O디바이스를 4개까지 확장지원가능하면서 제2, 제3의 SCSI를 지원 가능한 SCSI버스를 사용하여 I/O디바이스를 지원하도록 구성하였다.Therefore, in the present invention, a SCSI interface connects TSHA to the system bus MFB, and an I / O bus can support up to four I / O devices while using a SCSI bus capable of supporting second and third SCSI. It is configured to support I / O devices.
