Fibre Channel: The Proven and Reliable Workhorse for Enterprise Storage Networks

Mission-critical assets such as virtualized and database applications demand a proven enterprise storage protocol to meet their performance and reliability needs. Fibre Channel has long filled that need for most customers, and for good reason. Unlike competing protocols, Fibre Channel was specifically designed for storage networking, and engineered to deliver high levels of reliability and availability as well as consistent and predictable performance for enterprise applications. As a result, Fibre Channel has been the most widely used enterprise protocol for many years.

But with the widespread deployment of 10GbE technology, some customers have explored the use of other block protocols, such as iSCSI and Fibre Channel over Ethernet (FCoE), or file protocols such as NAS. Others have looked to Infiniband, which is now being touted as a storage networking solution. In marketing the strengths of these protocols, vendors often promote feeds and speeds, such as raw line rates, as a key advantage for storage networking. However, as we’ll see, there is much more to storage networking than raw speed.

It turns out that on an enterprise buyer’s scorecard, raw speed doesn’t even make the cut as an evaluation criteria. Instead, decision makers focus on factors such as a solution’s demonstrated reliability, latency, and track record in supporting Tier 1 applications. When it comes to these requirements, no other protocol can measure up to the inherent strengths of Fibre Channel in enterprise storage environments.

Despite its long, successful track record, Fibre Channel does not always get the attention and visibility that other protocols receive. While it may not be winning the media wars, Fibre Channel offers customers a clear and compelling value proposition as a storage networking solution. Looking ahead, Fibre Channel also presents an enticing technology roadmap, even as it continues to meet the storage needs of today’s most critical business applications.

In this paper, we’ll begin by looking at the key requirements customers should look for in a commercial storage protocol. We’ll then examine the technology capabilities and advantages of Fibre Channel relative to other protocols, and discuss how those translate to business benefits. Since not all vendor implementations are created equal, we’ll call out the solution set of one vendor – QLogic – as we discuss each of the requirements, highlighting it as an example of a Fibre Channel offering that goes well beyond the norm.

InfiniBand Updates Specs Preparing for 10000 Node Exascale Clusters

We've long been fans of InfiniBand, watching as new generations of enterprise class scale-out clusters and storage solutions learn from the HPC world how to achieve really high-speed interconnection. InfiniBand itself may never win the popular market race against Ethernet, but newer generations of Ethernet are looking more and more like InfiniBand. And parts of the IB world, namely RDMA and RoCE, have swept into datacenters almost unaware (e.g. look under the hood of SMB 3.0).
