1–Overview of the <strong>QLogic</strong> <strong>Fabric</strong> <strong>Manager</strong> Suite<br />
Multiple <strong>Fabric</strong> <strong>Manager</strong>s in a <strong>Fabric</strong><br />
The embedded <strong>QLogic</strong> <strong>Fabric</strong> <strong>Manager</strong> is licensed software, and is tied to a<br />
managed edge switch or <strong>QLogic</strong> 12000 Management Module. A license key must<br />
be obtained from <strong>QLogic</strong> and entered into the switch (using either the <strong>QLogic</strong><br />
Chassis Viewer or CLI interface) before the <strong>QLogic</strong> <strong>Fabric</strong> <strong>Manager</strong> components<br />
can be started.<br />
The embedded <strong>QLogic</strong> <strong>Fabric</strong> <strong>Manager</strong> is accessed through the switch CLI using<br />
commands in the “SubnetManagement” command group, as well as a few<br />
screens in the <strong>QLogic</strong> Chassis Viewer GUI interface for a management module or<br />
edge switch. The majority of the configuration for the FM is accomplished using a<br />
qlogic_fm.xml file which can be loaded onto the switch using the GUI or<br />
Fast<strong>Fabric</strong>.The CLI contains many commands that provide access to<br />
configuration items and operational status. Both the web interface and CLI provide<br />
controls for the embedded <strong>QLogic</strong> <strong>Fabric</strong> <strong>Manager</strong> to be started automatically at<br />
chassis boot time. Additionally, they provide the ability to start and stop the<br />
embedded <strong>QLogic</strong> <strong>Fabric</strong> <strong>Manager</strong>.<br />
Choosing Between Host and Embedded <strong>QLogic</strong> <strong>Fabric</strong><br />
<strong>Manager</strong> Deployments<br />
Please refer to the release notes of IFS software or embedded firmware for more<br />
guidance in choosing between deploying a host or embedded <strong>QLogic</strong> <strong>Fabric</strong><br />
<strong>Manager</strong> solution.<br />
Multiple <strong>Fabric</strong> <strong>Manager</strong>s in a <strong>Fabric</strong><br />
It is possible to deploy more than one <strong>Fabric</strong> <strong>Manager</strong> in a fabric. Normally<br />
deploying more than one <strong>Fabric</strong> <strong>Manager</strong> is done to provide redundancy. Multiple<br />
<strong>Fabric</strong> <strong>Manager</strong>s are a way to ensure that management coverage of the fabric<br />
continues unabated in the case of the failure of one of the <strong>Fabric</strong> <strong>Manager</strong>s.<br />
<strong>Fabric</strong> <strong>Manager</strong> State – Master and Standby<br />
When multiple <strong>Fabric</strong> <strong>Manager</strong>s are present in a fabric, one takes on the role of<br />
master <strong>Fabric</strong> <strong>Manager</strong> through arbitration. All other <strong>Fabric</strong> <strong>Manager</strong>s taken the<br />
role of standby <strong>Fabric</strong> <strong>Manager</strong> and use SM-to-SM communication to monitor the<br />
presence of the master <strong>Fabric</strong> <strong>Manager</strong>.<br />
