Fibre Channel Over Ethernet: A Pragmatic Approach to Data Center Network Convergence
As the needs for data center connectivity have evolved, enterprises have typically deployed discrete technologies in silos to address distinct networking requirements. Core business application traffic flows across Ethernet LAN networks. Storage data travels between servers and corresponding storage devices via a Fiber Channel based Storage Area Network (SAN), while ultra High-Performance Computing (HPC) environments rely on low-latency InfiniBand networks. However, as traffic volumes mount and data storage requirements increase, enterprises today are struggling to cope with the multiple networks they've built up over the years. Having to support three distinct networks (LAN, SAN, HPC) - each with its own technologies, protocols and management requirements - creates significant challenges and can lead to dramatic increases in cost and complexity of data center operations.
