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.
Definition domain validation Before sending data, domain validation verifies that the physical connection is capable of handling the negotiated transfer speed. If the system determines that Ultra320 speeds are not feasible, a slower speed is enforced. 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.
2 ATTO ExpressPCI provides 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. The ATTO ExpressPCI UL4S is a single channel Ultra 320 SCSI, PCI-X host adapter while the ATTO ExpressPCI UL4D is a dual channel Ultra 320 SCSI, PCI-X Host Adapter. Today’s computing applications continue to strain the host PCI bus and storage subsystem.

3 Installing hardware 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 Ultra320 SCSI devices. WARNING Remember to back up your system data before changing or installing hardware. System requirements The ATTO Express PCI host adapter package contains the host adapter, the ATTO Express ProTools CD and a warranty and registration card.
Refer to the ATTO ExpressPCI Utilities Installation and Operation manual for more information on changing host adapter settings. Installation and configuration 10 ATTO ExpressPCI host adapters come preconfigured to operate properly in a variety of common system setups. However, some systems or setups may benefit by tuning the adapter for optimal performance.
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 devices you may connect at specific cable Exhibit 3.1-1 STA terms distances using differential and single-ended SCSI in various SCSI environments. The development of SCSI capabilities Bus speed Bus width Max.
3 Determine which terminator to use 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. Some termination manufacturers provide automatically sensing terminators.
3.2 Installing and Updating Device 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. 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. Windows Server 2003 & Windows 2000/XP channel.
installation disk and any other vendor-supplied disks you used during custom installation. This is normal. The first time you inserted the disks, Windows loaded the drivers into memory; the second time, Windows copied the driver to the hard disk. Windows NT Installation To install/upgrade the Windows NT driver Log on to Windows as the system administrator. 2 Open the SCSI Adapters applet in the Control Panel 3 Click on Drivers tab. 4 Click Add... 5 Click Have Disk...
To install a new copy of Windows NT onto a SCSI disk attached to your ExpressPCI adapter. 1 2 3 4 5 6 Start Windows NT text mode setup as per the instructions provided with Windows NT. Press F6 when the first blue window, Windows NT Setup, appears. Setup will continue to load files. After loading the setup files, you will be given several choices. Press Enter to install Windows. From the list of devices detected by Windows, press S.
Mac OS X drivers, including installer packages, can be downloaded directly from the ATTO web site, www.attotech.com. The driver installers will automatically unionist existing drivers and properly install the new drivers on your system. After installing, the new adapter driver you will need to update the firmware. The ATTO ExpressPCI Configuration Tool, available on the ATTO web site, www.attotech.com/software/index.html, will verify drivers and firmware versions and attempt to flash.
4 Maximizing Performance with your ExpressPCI HBA 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.
Increase transfer size If you are writing to an application that uses a lot of sequential disk I/O to a contiguous area on disk, you should use as large a transfer size as possible to reduce overhead on the system, on the SCSI bus and within disk drives.
5 Troubleshooting This chapter contains solutions for the most common problems you might encounter. If you need additional assistance, please refer to the ATTO Technology web site (www.attotech.com) or contact an ATTO Technology authorized representative. General suggestions ❖Check each cable connection on every device. Verify all cables are in proper working condition. Loose or broken cables are often the cause of errors or problems.
1 Open the SCSI Adapters utility in the Control Panel under Settings. 2 Verify the ATTO ExpressPCI host adapter 64-bit PCI SCSI host adapter appears under the Devices List. 3 If it does not appear in the Device List, verify that the adapter is seated properly in the PCI slot (remove power from the PC, remove its case, check the PCI slot, replace the case, apply power). 4 If it has been identified, click on the Drivers Tab to see if the ATTO ExpressPCI host adapter driver has been started.
