IBM QLogic 16Gb FC Dual-port HBA

IBM QLogic 16Gb FC Dual-port HBA is a host bus adapter designed to provide high-speed Fibre Channel connectivity between servers and SAN storage. With two 16Gb/s ports, this HBA enables low-latency, high-throughput links that support enterprise storage traffic and virtualization environments. The adapter is intended for rack and blade servers where reliable, consistent fabric connectivity is required for I/O-intensive applications.

Advantages

The dual-port design offers redundancy and flexible zoning options for SAN topologies, while 16Gb/s data rate support allows for increased throughput compared with previous-generation Fibre Channel adapters. Hardware offload features reduce host CPU usage for storage I/O processing, improving overall system efficiency. The adapter is compatible with common Fibre Channel switches and storage arrays, providing predictable performance and stable connectivity in mixed-vendor environments.

Suitable for

• Connecting servers to SAN storage for virtualization platforms
• High-transaction database workloads requiring low-latency I/O
• Redundant SAN configurations and multipathing setups
• Storage consolidation and backup/replication traffic

Key specifications

• Interface type: PCIe host bus adapter
• Ports: 2 external Fibre Channel ports
• Data rate: 16 Gb/s per port
• Protocol support: Fibre Channel (FC)
• Operational features: hardware offload for storage I/O, support for multipathing
• Form factor: low-profile compatible for standard server chassis

How to use

Install the IBM QLogic 16Gb FC Dual-port HBA into an available PCIe slot on a supported server and secure it following standard server maintenance procedures. Connect each Fibre Channel port to the SAN fabric using compatible optical transceivers and fibre optic cables or direct-attach options as supported by the environment. Load or verify vendor-supplied drivers and firmware for the operating system in use, configure zoning on the Fibre Channel switches, and set up multipathing software if redundancy and path failover are required.

Usage recommendations

Use quality SFP+ / Fibre Channel transceivers and multimode or single-mode fibre matching the SAN switch and storage array specifications. Keep firmware and drivers up to date to ensure compatibility and performance. For critical workloads, deploy both ports to separate fabric paths and enable multipathing to provide failover and load balancing.
