1 What is ATTO ExpressPCI? Compatible with virtually all popular SCSI devices, ATTO ExpressPCI host adapters will increase the performance of disk-intensive applications such as digital video, prepress, multimedia and real-time.
Maximum Host PCI transfer rate: 32-bit/33MHz: 133 MB/sec. 32-bit/66 Mhz: 266 MB/sec. 64-bit/33 Mhz: 266 MB/sec. 64-bit/66 Mhz: 532 MB/sec. Maximum SCSI transfer rate: Synchronous data rate (UL3D/UL3D-66): 60 MB/sec. per channel (Ultra3 mode) Asynchronous data rate:12 MB/sec.
2 SCSI is a key technology for storage SCSI is a serial communications technology designed to transfer large amounts of data between a variety of hardware systems over long distances. It is a key technology for applications that require shared, high bandwidth access to storage. SCSI provides a logical point-to point serial channel for the transfer of data between a buffer at a source device and a buffer at a destination device.
Definition topology logical layout of the parts of a computer system or network and their interconnections transceiver a transmitter/receiver module transfer rate the rate at which bytes or bits are transferred, as in megabytes or gigabits per second.
3 Installing the ExpressPCI SCSI Host Adapter You will need a basic understanding of SCSI before installing the ATTO ExpressPCI host adapter. Please refer to Chapter 2 for a list of SCSI-related web sites. For more detailed explanations of cabling, connectors and termination, see Chapter 3.1. WARNING Remember to back up your system data before changing or installing hardware. WARNING ATTO ExpressPCI host adapters contain components that are sensitive to electrostatic discharge (ESD).

3.1 Determining 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 for proper performance. SCSI cables and devices are subject to specific length and number limitations to deal with electrical problems that arise at increased operating speeds.
one industry standard 68-pin “P” (16-bit) cable connector for internal device connections and one 68-pin “P” (16-bit) VHDCI (Very High Density Cabled Interconnect) cable connector for external device connections. ATTO ExpressPCI UL3D/UL3D-66: two industry standard 68-pin “P” (16-bit) cable connectors for internal device connections and two 68-pin “P” (16-bit) VHDCI (Very High Density Cabled Interconnect) cable connectors for external device connections.
jumper placed over the pins designated for supplying termination. Check with your drive manufacturer if you are not sure which pins to use. LVD Ultra2 and Ultra3 SCSI devices are not capable of supplying their own termination. Instead, termination must be supplied by an outside source, usually an internal ribbon cable which has a SCSI terminator attached to the end. Connect the non-terminated end of the cable to the host adapter card and the internal drives to the subsequent connectors.

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.
After all other drivers have been processed, press Enter and proceed with the rest of the Windows Installation procedure. NOTE When Windows begins copying files to your hard disk, you will again be prompted to insert the ExpressPCI 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.
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.
verify drivers and firmware versions and attempt to flash. Instructions for using this utility are provided as part of the download process. Updating Drivers and Re-flashing Firmware in Mac OS 9 To re-flash the firmware to the latest version: 1 2 3 Obtain the latest firmware and updater program from the ATTO web site www.attotech.com and download to your host. Create a folder or drive where you want the program files to be placed.
4 Maximizing Performance with 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. 9 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.
