Host Bus Adapters

Two types of HBAs are available:
•
•
The stand-up HBAs are low-profile MD2 form factor PCI Express (PCIe) cards, measuring 6.6 in. by
2.714 in. (16.765 cm by 6.89 cm), that install in standard host computer systems. HBAs are
shipped with a low-profile bracket installed and a standard bracket included for mounting in your
host system). These HBAs contain either one or two external ports for connecting to Fibre Channel
switches via fiber optic cable.

The mezzanine type HBAs are smaller cards. For example, the Brocade 804 adapter measures
approximately 4 in. by 4.5 in. (10.16 cm by 11.43 cm). Mezzanine adapters mount on server blades
that install in supported blade system enclosures. Refer to
references to HBA compatibility information. Note that mezzanine adapters do not have external
port connectors with optics such as stand-up HBAs, but internal ports that connect to the switch
and interconnect modules installed in the enclosure through high-speed links in the internal
enclosure backplane.

PCI Express interface

Install Brocade stand-up HBAs in PCI Express computer systems with an Industry Standard
Architecture/Extended Industry Standard Architecture (ISA/EISA) bracket type.
Install Brocade mezzanine HBAs in supported blade servers that install in supported blade system
enclosures. Multiple HBAs may be mounted in connectors located at different locations in the
blade server.
Following are some of the features of the PCIe interface:
