Sun 501-5202-03 DUAL FC-AL HBA SBUS(PC4A 1)(P12B20C2) PTG4B(4883)-2C(P9C29-4C)

Product Description

The Sun 501-5202-03 is a dual-channel Fibre Channel Arbitrated Loop (FC-AL) Host Bus Adapter (HBA) specifically designed for Sun Microsystems' legacy SPARC-based systems that utilize the SBUS expansion interface. This adapter provides two independent FC-AL channels, enabling connectivity to Fibre Channel storage devices and networks that operate using the arbitrated loop topology. This HBA is crucial for systems that require high-speed, reliable access to storage in environments where SBUS was the primary expansion bus. The FC-AL protocol allows multiple devices to share a common loop, with a mechanism for arbitrating access to the loop. The dual-channel design offers redundancy and potentially increased throughput compared to single-channel solutions. The associated identifiers such as PC4A 1, P12B20C2, PTG4B(4883)-2C, and P9C29-4C likely refer to specific revisions, configurations, or internal component designations of this adapter. As an SBUS-based adapter, it represents a solution for older Sun hardware platforms that may still be in use for specific legacy applications or environments.
