Installation manual

73 ATTO Technology Inc. ATTO Utilities Installation and Operation Manual
2.1 FC BIOS Configuration Utility
Default NVRAM settings work for most applications, but your particular hardware configuration may require some
changes. Fibre Channel storage controller NVRAM settings may be changed from the
BIOS Configuration
Utility.
The Configure Adapter Channels menu selection
displays a dialogue which contains the parameters for
a specific adapter.
Adapter Node Name
The Node WWN assigned to this channel of the adapter.
Adapter Port Name
The Port WWN assigned to this channel of the adapter.
Adapter Number
Choices: Variable
Default: 0
Choices depend upon the number of Fibre Channel adapters
installed in your computer and the number of channels per
adapter. If one single channel adapter is installed,
0 is the only
choice. If two dual channel adapters are installed, choices are
0, 1, 2 and 3 .
Data Rate
Choices for 4 Gig: 1 Gb/sec., 2 Gb/sec., 4 Gb/sec, Auto
Choices for 8 Gig: 2 Gb/sec., 4 Gb/sec., 8 Gb/sec, Auto
Default: Auto
Selects the Fibre Channel transmission rate. If
Auto chosen,
the adapter determines the rate based upon the devices
connected.
Connection Mode options
Choices: AL, PTP, AL Preferred, PTP Preferred
Default: PTP Preferred
Arbitrated Loop (AL) : Connects to either an FCAL Arbitrated
Loop or a Fabric Loop Port (FL Port) on a switch.
Point-to-Point (PTP) : Connects to a direct Fabric
connection, such as an F port on a switch.
AL Preferred: Allows the card to determine what kind of
connection to use, but tries to connect in Loop mode first, then
Point-to-Point mode.
PTP Preferred: Allows the card to determine what kind of
connection is to use, but tries to connect in Point-to-Point mode
first, then Loop mode.
Current Boot Node Name
Displays the IEEE worldwide address assigned to the current
boot device.
Current Boot LUN Number
Displays the LUN address assigned to the current boot device.
Device Discovery By
Choices: Node WWN, Port WWN
Default: Port WWN
Specifies the type of device discovery the adapter performs.
Use the Port WWN when the adapter requires separate paths to
a device and the device is dual ported. A dual ported device has
one path when the Node WWN is specified and two paths when
the Port WWN is specified.
Enable Selectable Boot
Choices: Yes, No
Default: No
Specifies a boot device to use other than BIOS device 80. If you
select
yes , a page listing the devices connected to the storage
controller displays. Select the device from which you wish to
boot and press
Enter .
Execution Throttle
Choices: 1-255
Default: 16
Specifies the maximum number of concurrent commands active
for a port. Increasing this value may increase performance, but
you may saturate a drive with commands, decreasing
performance.
Frame Size
Choices: 512, 1024, 2048
Default: 2048
Changes the size of the FC packet of information being sent.
Typically, the initiator and target negotiates the desired frame
size, starting with the largest value. The frame size should be
set to the largest value for normal operation. However, some
older devices may not properly negotiate frame size: use
Frame Size to specify the size rather than permitting
negotiation.
Hard Address
Choices: None, 0-125
Default: None
When a Fibre Channel loop is initialized, each device selects
and configures itself to an available ID.
Hard Address
Enable
permits the host to select the value entered in the Hard
Address
field.
