1 SCSI is a key technology for storage Ultra320SCSI 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 Ultra320SCSI solutions The Ultra320SCSI 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. The ATTO ExpressPCI UL4S is a single channel Ultra320SCSI, PCI-X host adapter, the ATTO ExpressPCI UL4D is a dual channel Ultra320SCSI, PCI-X host adapter, and the ATTO ExpressPCI UL5D is a dual channel Ultra 320 SCSI PCI Express (PCIe) host adapter.

3 Hardware installation Install the ATTO ExpressPCI Ultra320host 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. The following table lists the maximum number of distances using differential and single-ended devices you may connect at specific cable SCSI in various SCSI environments. Exhibit 3-2 The development of SCSI capabilities STA terms Max.
3 • If you combine Wide 16-bit and Narrow 8-bit devices on the same connector, connect the Wide devices first (closest to the connector). • Please refer to the documentation for your SCSI devices to determine if they are Wide or Narrow, UltraWIDE SCSI, Ultra2 SCSI, Ultra160 or Ultra 320.
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. 2 Open the appropriate file and follow the installation instructions.
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.
6 Maximizing performance in Windows If you are getting less performance than you expect, there are several things you can do such as making sure you are using the latest ATTO driver, setting the registry entry for large block transfers, using ATTO ExpressRAID for setting up RAID groups, increasing transfer size, and analyzing your system’s I/Os.
If your application requires a small number of I/Os and the transfers are rather small, however, you may get better performance by letting the system cache your data in the system pages. You might want to use over-lapped I/O using the FILE_FLAG_OVERLAPPED option with the CreateFile call. Overlapped I/O allows the application to send many commands to the device at once.
Appendix A Standards and compliances The equipment described in this manual generates and uses radio frequency energy. The Technical Specification sheet for a particular ATTO ExpressPCI host bus adapter list certifications for that model. FCC standards: radio and television interference WARNING This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules.
