1 SCSI is a key technology for storage Ultra320 SCSI represents the seventh generation of SCSI technology, an I/O interface that increases performance while maintaining backward compatibility and legacy support. From its roots in 5 MB/sec. transfer rates, SCSI driving the unprecedented growth in storage that has evolved as the leading interface for disk drive pushes the I/O bandwidth, requiring more connections in high performance servers. It advanced interfaces to handle data transfer.
Term Definition double transition clocking Increases the data line frequency to equal that of the request signal, allowing sampling on both the leading and trailing edges of the request signal. Clocking can be set to ensure compatibility with legacy devices. flow control The target indicates to the initiator when the last packet of a data stream will be transferred so that the initiator can flush FIFOs and terminate pre-fetch sooner than previously possible.
2 ATTO ExpressPCI Ultra320 SCSI solutions The Ultra320 SCSI Host Adapter represents the seventh generation of SCSI technology, an I/O interface that is committed to increased performance while maintaining backward compatibility and legacy support.

3 Hardware installation Install the ATTO ExpressPCI Ultra320 Host Adapter and attach your SCSI devices to it using the instructions below. To get the best performance from your ATTO Express Ultra320 host adapters, use Ultra 320 SCSI devices. Devices in the middle of the bus, including the ATTO ExpressPCI adapter, must have termination removed or disabled. ATTO ExpressPCI SCSI adapters select the proper termination if left in auto termination mode.
6 Hardware installation
3.1 Cabling and termination Cables and devices must be chosen to maximize performance and minimize the electrical noise from the high-speed data transfers available with the SCSI protocol. Cabling and termination methods become important considerations. Exhibit 3.1-1 The following table lists the maximum number of devices you may connect at specific cable distances using differential and single-ended SCSI in various SCSI environments. Max. bus lengths, meters Bus speed Bus width MB/sec. max.
• A narrow terminator should be used on the last narrow device to terminate the rest of the SCSI bus. Use an LVD terminator if you are only using LVD devices. Although you can use a Single-Ended terminator, all devices will be limited to Ultra SCSI speeds. Single-Ended devices require a Single-Ended terminator. If you use an LVD terminator with SingleEnded devices, the system may hang or devices may not be seen on the SCSI bus.
4 Installing drivers After installing the ATTO ExpressPCI Host Adapter, you must configure your system to recognize and use it by installing drivers for your operating system. Note If you already have one or more ExpressPCI adapters installed and you are installing additional adapter(s), you do not need to perform any of these procedures unless you are updating a previously installed driver.
5 Updating hardware flash ATTO ExpressPCI adapters ship with the latest firmware installed. If you are performing a new adapter installation, you do not need to update the firmware. If you are upgrading a previously installed driver, update the adapter firmware to ensure proper operation. Visit the ATTO Technology website, Use the ExpressPCI BIOS Setup Utility www.attotech.com, for the latest drivers and Note firmware. BIOS utilities are not available on Itanium systems.
