IOI-A100U2W-Mac provides unmatched Ultra2 SCSI data transfers of up to 80 MByte/sec¡V that¡¦s 16 times faster than the built-in external SCSI in every Macintosh! Extended cable lengths of up to 12 meters for Ultra2 devices illustrate its system configuration flexibility. Thoroughly tested with the most common Mac peripherals,  IOI-A100U2W-Mac provides the speed, flexibility, and compatibility required to optimize today¡¦s most powerful Macintosh systems. 

The 32-bit PCI interface transfers data at the rate of 133 MByte/sec with a 33 MHz PCI clock. The Ultra2 SCSI interface is capable of bursting data at 80 MByte/sec on the bus. This high speed interface with its embedded I/O processor makes IOI-A100U2W-Mac suited for servers and professional desktops. IOI-A100U2W-Mac uses little or no CPU bandwidth by off-loading all the I/O tasks to the 32-bit I/O processor embedded in the controller. This results in very high system performance in I/O intensive applications such as multimedia, imaging, client server databases, intranet applications, web tools and RAID subsystems that require high availability and throughput. 

While IOI-A100U2W-Mac is capable of keeping pace with the most demanding applications, it offers complete compatibility with your existing SCSI peripherals. You can combine SCSI-1, SCSI-2, SCSI-3 or UltraSCSI peripherals for optimum performance and value. In Ultra2 SCSI modes, the SCSI I/O pad design allows cable lengths of up to 12 meters, and in point-to-point configurations cabling can be extended up to 25 meters. This increased cable length provides greater flexibility in system configurations, especially in clustering and RAID applications.

IOI-A100U2W-Mac features SmartSCSI, a user friendly setup utility that allows configuration of individual SCSI devices and host adapter termination via the keyboard. Updates to the firmware can also be accomplished with SmartSCSI¡¦s intuitive interface. And the field upgradeable BIOS utility makes upgrading your system fast and easy. 

IOI-A100U2W-Mac guarantees compatibility with the latest version of Mac OS-compatible systems. The newest in a family of PCI-to-SCSI host adapters from IOI, IOI-A100U2W-Mac has been fully tested to deliver the utmost in reliability and performance.
