A Pragmatic Approach to Data Center Network Convergence

As traffic volumes continue to mount, enterprises must cope with the multiple network silos they have built over the years to address their evolving data center needs.

They often must support three distinct networks—a local area network (LAN) for core business application Ethernet traffic, a Fibre Channel storage area network (SAN) for storage data traveling between servers and corresponding storage devices, and high-performance computing (HPC) environments that rely on low-latency InfiniBand networking. Significant challenges are created by the distinctive technologies, protocols, and management requirements of each of these networking environments, frequently resulting in dramatic cost increases and operational complexity. Clearly, enterprises must find a way to simplify data center infrastructures and reduce operational expenses. Many have decided that the best approach is to chart a measured route toward a unified infrastructure. Gradual migration is the logical approach - one characterized by low risk and high reward. Leaping directly to a unified network architecture can be too risky, not to mention costly and disruptive.

As enterprises consider options for enabling a sensible migration to a converged network scenario, emerging Fibre Channel over Ethernet (FCoE) technology quickly comes to the fore. Developed by a group of storage and data network vendors working within the INCITS T11 committee, FCoE is designed to let native Fibre Channel and standard network traffic run alongside each other over a 10 Gigabit Ethernet infrastructure. The Fibre Channel frames are encapsulated over the Ethernet network, allowing the consolidation of computing and storage (LAN and SAN) I/O environments at the server network edge in a high-performance, low-cost, and standardsbased manner.
