DEC KGPSA-EA 2 GB Host Bus Adapter

Product Description

The DEC KGPSA-EA is a Host Bus Adapter (HBA) that operates at 2 Gigabaud (GB), indicating it is a Fibre Channel adapter. Fibre Channel is a high-speed networking technology primarily used for storage area networks (SANs). This HBA allows a server or workstation to connect to a SAN, enabling high-performance access to storage devices like disk arrays and tape libraries. As a 2 GB Fibre Channel adapter, it supports data transfer rates of up to 200 MB/s per port (2 Gigabaud is approximately 200MB/s in each direction). This was a significant speed for storage networking during its era. The adapter would typically interface with the host system via a PCI or PCI-X slot, depending on the server's architecture. Its primary function is to manage the Fibre Channel protocol, ensuring reliable and efficient data transmission between the host and the SAN fabric. The KGPSA-EA would have been used in enterprise environments where high availability, performance, and scalability of storage were critical. It enables features like storage virtualization, data replication, and centralized storage management by providing a dedicated, high-speed channel to shared storage resources. The specific connector type (e.g., LC, SC) and optical transceiver type (e.g., short-wave, long-wave) would depend on the specific model and intended network configuration.
