The Initio Ini-9100U/9100Uw Host Adapter - Initio INI-9100U User Manual

Introduction

The Initio INI-9100U/9100UW host adapter

The INI-9100U and INI-9100UW are high-performance PCI bus master host
adapters which provide the interface between the SCSI bus and the PCI local
bus. In this User's Manual we use the term INI-9100U/9100UW to refer to
both host adapter models. The Initio INI-9100U/9100UW supports 32-bit data
transfers across the high bandwidth PCI bus at speeds up to 133 MBytes per
second. The advanced Integrated Scatter/Gather Engine (ISGE) reduces the
command overhead time enhancing the overall system response, thus providing
exceptional performance for the Initio INI-9100U/9100UW PCI-SCSI host
adapter.
An on-board utility program is designed into the host adapter to simplify SCSI
bus set up. The SmartSCSI Setup Utility program enables simple integration
of the INI-9100U/9100UW into most platforms and with many operating
systems. The SmartSCSI Setup Utility will enhance the installation procedure
of the host adapters and allow for complete self-integration in those systems
that implement the current plug and play standards. The INI-9100U/9100UW
complies with plug and play applications on systems using the PCI bus
standard.
The INI-9100U host adapter will support asynchronous SCSI bus transfers to a
maximum rate of 5 MBytes per second and synchronous ultra SCSI bus
transfers to a rate of 20 MBytes per second. The INI-9100UW host adapter will
support asynchronous SCSI bus transfers to a maximum rate of 10 MBytes per
second and synchronous ultra wide SCSI bus transfers to a rate of 40 MBytes
per second, as well as ultra SCSI transfers to a rate of 20 MBytes per second.
Full support of UltraSCSI defined by the SCSI-3 specification,
disconnect/reconnect and command queuing provides maximum bus utilization
in multiple target implementations.
