Converged Enhanced Ethernet-Good for iSCSI SANs
The introduction of new features to enhance the Ethernet protocol will improve the performance characteristics of storage applications. Although commonly associated with an emerging standard, Fibre Channel over Ethernet (FCoE), these new enhancements will contribute to improved performance of iSCSI storage traffic as well. The continuing expansion of 10 Gigabit Ethernet combined with lossless Ethernet supports mixing of traffic types between servers, switched networks, and networked storage targets. Lossless Ethernet extensions (PFC, ETS, Bridging, and Congestion Notification) enable a 10 Gigabit Ethernet connection to support multiple traffic types simultaneously, preserving their respective traffic properties. With these extensions, the same 10 Gigabit Ethernet link can enhance iSCSI performance and robustness and also be able to support Fibre Channel storage traffic by offering a no-drop capable consolidated I/O fabric.
