The IOI-4206LVD features the flexibility, speed, and compatibility required to optimize today's PC servers and workstations.  IOI-4206LVD provides unmatched Ultra2 SCSI data transfers of up to 80 Mbytes/sec- that's twice the speed of UltraWide SCSI and up to 8 times the speed of conventional FastSCSI.  Extended cable lengths of up to 12 meters for Ultra2 devices illustrate IOI-4206LVD's system configuration flexibility.   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 Ultra2 interface capable of bursting data at 80 MByte/sec on the SCSI bus.  These high speed interfaces and an embedded I/O processor makes IOI-4206LVD 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-4206LVD 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 12 meters.  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.  The IOI-4206LVD host adapters feature SCSI Configuration Utility, a user friendly, BIOS resident setup utility that allows individual device configuration, host adapter termination, and PCI Plug n' Play installations via the keyboard.  The IOI Manager Set makes your SCSI software utility makes upgrading your system fast and easy.
