4LEDs indicate the real-time status of the adapter, Fibre Channel or Ethernet link status, and link activity. LED patterns are described in detail in “Troubleshooting with LEDs” on page A-1.

5Non-volatile random access memory (NVRAM) is used to store the per-port adapter config- uration parameters. These parameters are typically loaded at manufacturing and should not be modified except by those who have an expert level understanding of the functioning of QLogic Fibre Channel and Converged Network Adapters. During adapter initialization, the parameters are accessed and used to configure the adapter. Examples of adapter con- figuration parameters include Fibre Channel connection type (topology), Fibre Channel data rate, Fibre Channel tape support, and so on.

Software Components

This section describes the following QLogic adapter software components:

Boot Code

OS Driver

Firmware

Management Tools and Utilities

Boot Code

Boot code resides on the Flash memory on the adapter. The primary function of the boot code is to communicate with an external boot device before the operating system takes the control over when booting from a storage device attached to the QLogic adapter. This type of configuration is referred to as boot from SAN.

OS Driver

For all QLogic Fibre Channel Adapters currently supported on VMware ESX/ESXi 4.0, the driver is supported natively with ESX; that is, no separate driver installation is required for VMware ESX/ESXi 4.0 to recognize the QLogic Fibre Channel Adapters. QLogic Fibre Channel Adapters on VMware ESX/ESXi 4.0 require no additional driver installation steps to run the adapters. In some specific cases, you may need to download from the VMware Web site one of the following:

A VMware Approved Driver CD

(http://driverdownloads.qlogic.com/QLogicDriverDownloads_UI/default.aspx)

ESX/ESXi patches that might include specific fixes for adapters or enable new adapters.
