Storage Consolidation for Data Center Efficiency

One trend in the data center that has shown consistent progress is the convergence of switching fabrics. Servers in data centers are typically connected to three different network areas: Storage, TCP/IP and Cluster networking. Because these areas have different requirements, different switching fabrics are sometimes used: Fibre Channel, Ethernet and InfiniBand. An important aspect of Ethernet’s value proposition is the possibility of using it in all network areas to provide servers with a single connection. Consolidating to an Ethernet fabric greatly reduces the amount of equipment required in the data center and drastically lowers both power consumption and the overall cost of administration. According to a paper by blade.org,

The Benefits of Ethernet for IP-based Storage Networking

As enterprise data centers continue to deploy more powerful processors and clustering for compute capacity, the need for terabits of storage capacity is becoming standard. IP storage solutions such as NAS, iSCSI, and FCoE, can all benefit from the high-bandwidth, low-latency, and scalability of 10 GbE, including:

Consolidation of native SANs over a common high-speed, low-latency 10 GbE backbone.
Elimination of congestion and I/O bottlenecks.
Disaster recovery and remote site backup operations rely on the optimal performance of the intervening IP and Ethernet network.

High-throughput, high-availability and low-latency are crucial requirements of the IP storage network, which can readily be provided by the IBM System Networking family of blade and top-of-rack Ethernet switches.
