FC 4Gbps PCI-X Adapter hard loop ID

This setting forces the adapter to attempt to use the ID specified in the

Hard Loop ID setting. The default is Disabled.

Hard loop ID

If the FC 4Gbps PCI-X Adapter Hard Loop ID setting is Enabled, the adapter attempts to use the ID specified in this setting. The default ID is 0. You should set this ID to a unique value from 0-125 if there is more than one adapter connected to a FC-AL loop, and the FC 4Gbps PCI-X Adapter Hard Loop ID setting is Enabled.

Spin up delay

When this bit is set, the BIOS will wait up to 5 minutes to find the first drive.

The default setting is Disabled.

Connection Options

This setting defines the type of connection (loop or point to point) or connection preference. The default is 2.

Fibre Channel Tape Support

This setting enables FCP-2 recovery. The default is Disabled. You should change this setting to Disabled if the HBA is connected to a DS4000 storage server. The DS4000 storage server does not support a tape device through the same Fibre-Channel HBA from the host server.

Data Rate

This setting determines the data rate. When this setting is 0, the FC 4Gbps PCI-X HBA runs at 1Gbps. When this setting is 1, the FC 4Gbps PCI-X HBA runs at 2Gbps. When this setting is 2, Fast!UTIL determines what rate your system can accommodate and sets the rate accordingly. The default is 2 (auto-configure). When the setting is 3, the FC 4Gbps PCI-X HBA runs at 4Gbps.

Advanced FC 4Gbps PCI-X Adapter Settings

Access the following advanced host bus adapter settings through the Configuration Settings menu in Fast!UTIL and select Advanced FC 4Gbps PCI-X Adapter Settings. The default settings for the FC 4Gbps PCI-X HBA are as follows:

Execution Throttle

This setting specifies the maximum number of commands executing on any one port. When the execution throttle of a port is reached, no new commands are executed until the current command finishes executing. The valid options for this setting are 1-256. The default is 256.

LUNs per Target

This setting specifies the number of LUNs per target. Multiple LUN support is typically for redundant array of independent disks (RAID) servers that use LUNs to map drives. The default is 256.
