Conventional Fibre Channel SAN (Storage Area Networks) are closed network environments, where devices are often expensive and lack flexibility in deployment. QNAP introduces dual-port Fibre Channel expansion cards that are characterized by high performance, reliability, security, and energy-efficient Fibre Channel. With a QNAP Fibre Channel card in your QNAP NAS, your NAS can be integrated into an existing SAN environment to meet the demands for high-performance storage and backup.
