•If these do not solve the problem, re-flash the host adapter and re-install the Windows 2000/XP/Server 2003/Vista/2008 driver. See Updating Hardware Flash, Drivers on page 25.

If the devices connected to the Celerity FC host adapter are not accessible:

1Click on the Start button

2Click Control Panel. (In XP, 2000 and 2003, click Settings then Control Panel.)

3Double click on Administrative Tools.

4Double click on Computer Management.

5Select Device Manager.

•If the Celerity FC host adapter does not appear under the SCSI and RAID controllers, remove

power from the PC, open the case, and check that the Celerity FC adapter is properly seated in the PCI slot. Replace the case and apply power.

•If the adapter has been identified but there is an exclamation point (!) on the listing, right click on the listing and select Uninstall.

6Reload the driver (see Updating Hardware Flash, Drivers on page 25).

7Reboot the system and repeat the installation process.

8If problems persist, contact your authorized ATTO Technology representative.

Linux

1Verify the celerityfc driver is loaded with the lsmod command. If lsmod does not show the driver, refer to the installation instructions to install and load the driver in Updating Hardware Flash, Drivers on page 25.

2Check the system log with the command dmesg. The celerityfc driver creates status messages during initialization. Make sure that all installed cards are properly detected and initialized.

3Examine the contents of the file(s) /proc/scsi/celerityfc/X, where X is the adapter’s host number. This file contains details such as link status, connection speed and discovered devices.

Note

Advanced users only. Modify the driver makefile to enable debugging information. Upon loading, the celerityfc driver displays detailed debugging information which may help troubleshoot the problem.

VMware

1After driver installation, please reboot host. Once the host is back online, go to Storage and create VMFS datastore. If storage does not appear, perform a rescan using the VMware Storage option. If your storage does not present itself, thereafter, please contact your SAN administrator.

FC-81EN, FC-82EN, FC-84EN specifications

ATTO Technology's FC-82EN is a 16Gb Fibre Channel HBA (Host Bus Adapter) that provides high-performance connectivity for storage area networks. Designed for use with both Windows and Linux operating systems, the FC-82EN is ideal for enterprises seeking to optimize data transfer rates and reduce latency for mission-critical applications.

One of the key features of the FC-82EN is its support for 16Gb Fibre Channel, which doubles the bandwidth from previous generations, allowing for faster data transfers. This is particularly beneficial in environments with heavy I/O workloads, such as virtualized data centers and large databases. With its backward compatibility, users can seamlessly integrate the FC-82EN into existing Fibre Channel networks that operate at 4Gb and 8Gb speeds, ensuring flexibility and protecting existing investments.

The FC-82EN employs advanced technologies to enhance performance and reliability. It incorporates ATTO's proprietary Advanced Data Streaming (ADS) technology, which optimizes data flow between the host system and storage devices. By minimizing processing overhead and maximizing throughput, ADS ensures that data-intensive applications run smoothly. Additionally, the HBA features a built-in intelligent caching mechanism to help manage data transfer and reduce bottlenecks.

Another significant characteristic of the FC-82EN is its support for multipathing, which enhances availability and load balancing across multiple paths in a storage network. This feature is crucial in distributed systems where uptime is critical, as it helps to prevent single points of failure and effectively utilizes available resources.

For manageability and ease of use, the FC-82EN includes ATTO's configurable driver and management software, providing users with a comprehensive suite of tools for monitoring performance, configuring settings, and troubleshooting issues. The adapter also supports end-to-end error detection and recovery protocols, ensuring data integrity throughout the transfer process.

In summary, the ATTO Technology FC-82EN is a robust and versatile Fibre Channel HBA that meets the demanding requirements of modern data environments. With its high-speed capabilities, advanced technologies, and strong management features, the FC-82EN is an excellent choice for organizations looking to enhance their storage network performance and reliability.
