Product Description
The IBM 18P3456, also identified by the part number 22R0464, is a high-performance Fibre Channel Host Bus Adapter (HBA) designed for enterprise-level storage area networks (SANs). This adapter boasts four 2 Gigabit per second (Gbps) Fibre Channel ports, enabling robust connectivity to storage arrays and SAN switches. The 'Longwave' designation indicates that these ports are intended for use with optical transceivers suitable for longer distances, typically found in large data center environments. Connectivity to the host server is established via the PCI-X 3.0 interface. PCI-X (Peripheral Component Interconnect Extended) was a standard for high-bandwidth, high-performance I/O buses, and version 3.0 offered significant improvements over its predecessors, providing ample bandwidth to support the aggregate throughput of four 2Gbps Fibre Channel ports. This makes the card suitable for demanding workloads that require fast and reliable access to block-level storage. As a quad-port HBA, the IBM 18P3456 offers redundancy and increased bandwidth options. Administrators can configure multiple paths to storage for high availability or aggregate the bandwidth of multiple ports for exceptionally demanding applications. This adapter is a critical component for IBM server systems requiring robust Fibre Channel connectivity for mission-critical applications such as databases, virtualization, and high-performance computing.
