It has also been thoroughly tested with several systems and peripherals to deliver the utmost in reliability and compatibility. The 32-bit PCI Interface transfers data at the rate of 133 MByte/sec with a 33 Mhz PCI clock. The SCSI interface is an Ultra

interface capable of bursting data at 40 MByte/sec on the SCSI bus. These high speed interfaces and an embedded I/O processor makes the IOI-4204UW uses little or no CPU bandwidth by off-loading all the I/O tasks to the 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 the IOI-4204UW host adapters are capable of keeping pace with the most demanding applications, they offer complete compatibility with your existing SCSI peripherals. You can combine SCSI-1, SCSI-2, SCSI-3 or UltraSCSI peripherals for optimum performance and value. The SCSI I/O pad design allows cable lengths of up to 3 meters.

The IOI-4204UW host adapters feature SmartConfig, a user friendly, BIOS resident setup utility that allows individual device configuration, and PCI Plug n' Play installations via the keyboard. The SDMS Driver Manager Set makes upgrading your system fast and easy.
