1 Features The HP StorageWorks U320e SCSI Host Bus Adapter represents the seventh generation of parallel SCSI technology, an I/O interface that is committed to increased performance while maintaining backward compatibility and legacy support. The HP StorageWorks U320e SCSI Host Bus Adapter is a dual channel Ultra 320 SCSI PCIExpress (PCIe) host adapter.
2 Installation CAUTION: Back up your system data before changing or installing hardware. Follow the steps in this chapter to install the host bus adapter. 11312 Figure 1 Kit contents The HP StorageWorks U320e SCSI Host Bus Adapter package includes: •...
WARNING! When installing the adapter in a server in a rack, to reduce the risk of personal injury or damage to the equipment, adequately stabilize the rack before extending a component outside the rack. Extend only one component at a time. A rack may become unstable if more than one component is extended. The installation procedure involves the following steps: Planning the installation (see page 14) Preparing the server (see page 16)
The last device in the bus — that farthest from the adapter — must be properly terminated for each SCSI bus. When planning device termination, keep the following in mind: • 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 and cable lengths.
Use a small, flat screwdriver to remove the four stand-offs on the external connectors, as shown in Figure 11315 Figure 3 Removing the stand-offs Remove the bracket and replace it with the low-profile bracket. Verify that the new bracket is oriented correctly, as shown in Figure 11316 Figure 4 Card with low-profile bracket...
Installing the adapter hardware CAUTION: Electrostatic discharge can damage electronic components. Be sure you are properly grounded before beginning this procedure. For more information, see "Appendix: Electrostatic discharge" on page 53. To install the host bus adapter hardware: Open the server case. WARNING! To reduce the risk of personal injury from hot surfaces, allow the drives and the internal system components to cool before touching them.
Power up the server and peripherals. The HP U320e SCSI Host Bus Adapter comes pre-configured to operate properly in a variety of common setups. However, some systems may benefit by tuning the adapter for a specific application. See Chapter on page 25 for information on changing host adapter settings. Installing drivers After installing the HP StorageWorks U320e SCSI Host Bus Adapter, you must configure your system to recognize and use it by installing drivers for your operating system.
Unzip the driver package and view the readme.txt file for release notes and installation instructions. HP provides patches for the AH627A driver in the Linux 2.4 and 2.6 kernels to allow the driver to operate on the HP StorageWorks U320e SCSI Host Bus Adapter. Updating firmware The HP StorageWorks U320e SCSI Host Bus Adapter ships with the latest firmware installed.
3 SCSI Domain Validation utility (Windows only) The SCSI Domain Validation utility tests the physical connection between host adapter and devices to ensure that the desired data transfer speeds can be achieved. Domain Validation eliminates the guesswork of determining transfer rates and is a handy tool for configuring SCSI busses. As SCSI performance has increased over the past several years, it has become more important to verify that the connections between the host adapter and storage devices, such as cables, connectors and target, are capable of handling high-speed data transfers.
Follow the directions in the installer to finish the installation. Running the Domain Validation utility To run the ATTO SCSI Domain Validation tool: Launch the tool. Select the adapter Channel of the SCSI bus, as shown in Figure Figure 6 Domain Validation Utility Select the tests to be run.

4 Configuration tool The HP StorageWorks U320e SCSI Host Bus Adapter ships with the latest firmware installed and configuration set to work in most installations. Use the ATTO Configuration Tool to see information about installed adapters, drivers and devices, and change NVRAM settings on the adapter. This program executes under: •...
Using the Configuration Tool NOTE: The HP StorageWorks U320e SCSI Host Bus Adapter is designed to operate properly using factory settings. Entering invalid or incorrect settings when using an NVRAM configuration utility, such as the ATTO Configuration Tool, may cause your host adapter to function incorrectly. CAUTION: Back up system data before installing or changing hardware configurations.
to the adapter and channel selected. See "NVRAM settings" on page 27 for information about the NVRAM settings. PCI information is displayed in the PCI Info tab. The current status of the Configuration Tool is represented in the Status window at the bottom of the display screen.

Fallback Sync Choices: 40/20, 20/10, and 10/5 Rate (MB/s) Default: 40/20 Specifies the maximum synchronous transfer rate to be negotiated when the adapter detects a Single-Ended SCSI bus. The bus is Single-Ended when Ultra SCSI devices are connected to the bus. Bus Reset Delay Read only;...
Page 29
Sync Rate (MB/s) Choices: Sync DT IU (320, 160), Sync DT (160, 80, 40), Sync ST WIDE (80, 40, 20, 10), Sync ST Narrow (40, 20, 10, 5) Default: Sync DT IU 320. If synchronous transfers are enabled, the sync rate specifies the maximum rate at which host bus adapter negotiates with the selected target ID.
5 Troubleshooting This chapter describes troubleshooting techniques that can be used to identify and resolve issues associated with the HP StorageWorks U320e SCSI Host Bus Adapter. Some of these techniques may seem simplistic or overly obvious, but these are the ones that are commonly overlooked and can take several hours of frustration to find.

process by eliminating the bus free phase. When combined with packetization, reduces command overhead and maximizes bus use. read and write Minimizes data transfer overhead by allowing a target to send one data stream data streaming (LQ) packet followed by multiple data packets. Minimizes overhead of data transfers because the target can send one data stream packet followed by multiple data packets.
