2.6.2 PCI Express Interface
The LSI Logic PCI Express interface operates as a x8 lane DMA bus
master. The narrow edge connector makes the PCI Express connection,
which provides connections on both the front and back of the board. The
signal definitions and pin numbers conform to the PCI Express base
Specification, Revision 1.0a. Refer to that specification for details
regarding the signal assignments.
2.6.3 FC Interface
The number of FC ports varies, depending on which specific LSI Logic
4 Gbit/s host adapter you have selected. Refer to
Section 2.8, “Physical
Characteristics,” for details.
2.6.4 FC Link Activity/Link Fault LED
All of the LSI Logic 4 Gbit/s host adapters feature a tri-color LED to
indicate link speed, link activity, and fault conditions. The LED(s) are
visible below the FC ports on the bracket. The LED color-code definitions
are detailed in the individual host adapter descriptions that follow.
2.7 Unique World Wide Name
Each LSI Logic FC port is assigned a unique 64-bit number called
World Wide Name (WWN) that is registered with IEEE. The first 4
hexadecimal characters are set at 0x1000 for all LSI Logic host adapters.
The last 12 hexadecimal characters of this number are printed on a label
affixed to the adapter. Multiport boards have only one label; WWN
enumeration for Port 0 begins with the value printed on the label, and
increments by one (+1) for each additional port.
2.8 Physical Characteristics
The LSI Logic 4 Gbit/s family of FC host adapters includes one to four
external FC connectors, depending on the specific host adapter you have
chosen. The host adapters are all available with optical interconnects. No
host adapter configuration is necessary.
