Host Bus Adapters

Figure 2-3. Example of Server Accessing Storage Systems Directly and Behind a PowerVault 530F

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 QLA2x00 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.”

QLogic QLA2200/66 and QLA2200F/66

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 QLA2200F/66 supports fiber-optic media. For additional information about HBA cabling, see Appendix A, “Cable Types.”
