Page 6: Scsi Is A Key Technology For Storage
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 has evolved as the leading interface for disk drive connections in high performance servers. - Page 7 Term Definition double transition Increases the data line frequency to equal that of the request signal, allowing sampling on clocking 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.

Page 12: Cabling And Termination
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. - Page 13 • 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 Single- Ended devices, the system may hang or devices may not be seen on the SCSI bus.

Page 14: 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. -
Page 15: Updating Hardware Flash
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, , for the latest drivers and www.attotech.com... -
