Host Bus Adapters

Within a SAN, a host bus adapter (HBA) provides the connectivity from the host com-

puter system to the external Fibre Channel device or to a PowerVault 50F, 51F, or 56F

switch. The following HBAs are supported.

QLogic QLA2100, QLA2100F, QLA2200, and QLA2200F

The QLA2

00 series HBAs support a 33-megahertz (MHz), 64-bit Peripheral Compo-

nent Interconnect (PCI) 2.1 interface (fully backward compatible with 32-bit PCI). The

QLA2100 and QLA2200 support copper media. The QLA2100F and QLA2200F sup-

port fiber-optic media. For additional information about HBA cabling, see Appendix A,

“Cable Types.”

The QLA2200/66 series HBAs support a 66-MHz, 64-bit PCI interface (fully backward-

compatible with 32-bit PCI). The QLA2200/66 supports copper media. The
