Take the headache out of troubleshooting faulty optics and cables with Emulex Gen 5 Fibre Channel HBA support for Brocade’s ClearLink (D_port) feature

Posted November 20th, 2013 by Barbara Porter

Data centers can have hundreds or thousands of optics and cables installed. If something goes wrong it can be like finding a needle in a haystack to find the faulty cable or optic. Emulex has partnered with Brocade to support their ClearLink Diagnostic port (D_port) feature on Emulex LightPulse® Gen 5 FC Host Bus Adapters (HBAs) to ensure optical and signal integrity for Gen 5 Fibre Channel (FC) optics and cables, and to simplify deployment and troubleshooting of high-performance networks. With ClearLink support, data centers now have the ability to track down faulty parts from the Brocade Gen 5 FC switch all the way to the Emulex Gen 5 FC HBA, reducing the troubleshooting process to a matter of hours vs. days. Emulex’s ClearLink support is available at no extra charge on Emulex Gen 5 HBAs. The management is integrated into the Emulex OneCommand® Manager application.

Here’s how ClearLink diagnostics work:

  • Performs a series of tests on both  Brocade Gen 5 FC switches and Emulex Gen 5 FC HBAs
  • Detects physical cabling issues that could result in  increased error rates and intermittent behavior,
  • Runs a series of tests, including local electrical loopback, loopback to the remote optics, loopback from the remote port to the local optics, and a full device loopback test, with data integrity checks, and
  • Provides an estimate of cable length to validate that a proper buffering scheme is in place.

Emulex ClearLink support will be available in Q1 2014 on Emulex LightPulse Gen 5 FC HBAs.
