The SYM22801 host adapter is a multi-function board providing two independent single-ended Ultra SCSI channels. Both SCSI channels are identical, offering increased connectivity without utilizing additional PCI slots. A single board provides a powerful dual channel, multitasking interface for Ultra SCSI peripherals such as disk, tape, CD-ROM, and other SCSI devices.
The SYM22801 leverages the SYM53C876 PCI dual channel SCSI multi-function controller capable of connecting directly to the PCI bus, presenting one electrical load, while functioning as a single 32-bit PCI DMA bus master.
The SYM22801 includes an on-board configuration utility allowing viewing and changing of default configuration settings for the host adapter and connected SCSI peripherals.
The device also provides advanced features for ease of use by modifying the on-board terminators depending on cable configuration and LEDs to help with termination power (TERMPWR) monitoring.
The SYM22801 has advanced features which makes it the right choice for applications requiring up to 30 connected peripherals, or for isolating peripheral classes (e.g. CD-ROMs and tape drives on one channel and high performance disk drives on the other).
