HBA Features and Specifications
The StorageTek Dual 8Gb FC Dual GbE ExpressModule HBA (SG-(X)PCIEFCGBE-Q8-Z,
SG-(X)PCIEFCGBE-Q8-N) consists of a single-wide, ExpressModule bus expansion
board. The board interfaces an eight-lane PCI Express bus, supporting two
Fibre Channel (FC) optical media ports and two UTP (copper) Gigabit
Ethernet ports. The two FC ports operate at 8 Gbit/second and feature
8/4/2 autonegotiation.
The HBA is also backward compatible with FC ports that operate
at 4 Gbit/second and 2 Gbit/second. The Gigabit Ethernet ports can
be configured to operate in 10-, 100-, or 1000-Mbit/second Ethernet
networks.
