HBA Features and Specifications
The StorageTek Dual 8 Gb FC Dual GbE HBA (SG-XPCIEFCGBE-E8-Z,
SG-PCIEFCGBE-E8-Z, SG-XPCIEFCGBE-E8-N, SG-PCIEFCGBE-E8-N, and 7105393) consists
of a single-wide, ExpressModule bus expansion board. The board interfaces an
eight-lane PCI-Express bus, with four lanes supporting two Fibre
Channel (FC) optical media ports and four lanes supporting two UTP
(copper) Gigabit Ethernet (GbE) ports. The two independent FC ports
operate at 8 Gbit/second and feature 8/4/2 Gbit/second autonegotiation.
The HBA is also backward compatible with FC ports that operate
at 4 and 2 Gbit/second. The Gigabit Ethernet ports can be configured
to operate in 10-, 100-, or 1000-Mbit/second Ethernet networks.
See Figure 1, Table 1, HBA Features and Specifications for a list of the HBA
features.
