Fibre Channel Features Refer to Section 11.4.2 for detailed information navigating the (SCSI) I/O Processors. As indicated in this section, double-clicking the (SCSI) I/O processor icon displays channel information about that processor. When doing the same on an FC I/O processor, note the only difference is the "TYPE" field changed to "FC" (see Figure C-5 for details). All other parameters remain the same for FC I/O processor(s) and FC devices. Figure C-5. ICP RAID Navigator Channel Information C.2.4 Configuring an FC-Enabled RAID Controller for Optimal Performance Correct configuration of your controller is crucial if attempting to attain the highest possible performance of the controllers. These are some of the areas that should be checked when considering optimal performance of your RAID controller: • Ensure that your FC-AL loops are initialized. See the section of your FC-enabled ICP RAID Controller's Hardware Guide entitled "Configuring Single and Dual Loops" to ensure that your loop is configured correctly. Also see Section C.1, Boot BIOS Message to ensure that your loops are initialized. • Ensure that your controller is running at a 2G Link Speed. To check, use one of these methods: - Enter ICPCON. Select "Save Information." Under "Controller Information," locate the field "Link Speed [MBaud]." This field should include "2125" if your 2G link is working correctly. or - Verify this information in the "Fibre Channel Information" window (see Section C.2.2). • Use a Dual-Loop configuration. See the section of your FC-enabled ICP RAID Controller's Hardware Guide entitled "FC-AL Single and Dual Loop Configurations" for details on how dual loops improve performance. • Ensure your controller is inserted in a 64-bit/66MHz PCI slot.
