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.
