Network, your next big storage problem!


Good post by Enrico Signoretti (thank you)

A few days ago I had an interesting chat with Andy Warfield at Coho Data and the topic of Network/Storage relationship came up several times. (Quick disclaimer: I’m currently doing some work for Coho)

In a couple of my latest articles (here and here) I talked about why many large IT organizations prefer PODs to other topologies for their datacenters but I totally forgot to talk about networking (I also have to admit that networking is not my field at all). So, this article could be the right follow-up for those posts.

Big Switch Networks has a big announce

Good post by Andrea Mauro (thank you)

Big Switch Networks is a company in the Software Defined Network (SDN) area with a clear declared mission: to bring hyperscale networking to a broader audience, by delivering fit-for-purpose products based on hyperscale networking technologies.

They have two main products: Big Tap Monitoring Fabric and Big Cloud Fabric. The first one is an entry level solution for monitoring existing networks, the second one is an advanced bare-metal SDN switching fabric intended for new data center pods such as private cloud, big data and virtual desktop infrastructure (VDI).

Despite being declared dead, Fibre Channel continues to evolve with FC-BB-6

Good post by Greg Schulz (thank you)

Like many technologies that have been around for more than a decade or two, they often get declared dead when something new appears and Fibre Channel (FC) for networking with your servers and storage falls into that category. It seems like just yesterday when iSCSI was appearing on the storage networking scene in the early 2000s that FC was declared dead yet it remains and continues to evolve including moving over Ethernet with FC over Ethernet (FCoE).

Why should CIO’s and business leaders care about Software Defined Networking

Good Post by Keith Townsend (thank you)

Software Defined Networking is a meaty topic and a good follow-up to last week’s conversation on Software Defined Storage.  There’s a lot at stake from both the software and hardware vendors in this space.  Both VMware, who’s trying to get their foot in the door and Cisco, who’s trying to maintain market dominance have skin in the game.  All SDN vendors have to answer the same question, do we really need this whole idea of a policy based programmable network?

The Software-Defined Data Center Myth

Good Post by Jesse St.Laurent (thank you)

I am writing this blog as I return home from the Software-Defined Data Center Symposium (thanks to Gestalt IT for a great event!). Attending and presenting at the symposium gave me an opportunity to speak with a lot of folks who are thinking about Software-Defined Data Center (SDDC) and how it fits into their environments.

Mellanox open sources its switch software as SDN pressures vendors to react

Post by Stacey Higginbotham (thank you)

Mellanox, a company better known for selling Infiniband products, will open source its Ethernet switching code. It’s a response to software-defined networking and the commodification of networking gear.

SDN is coming soon to a network near you

Good post on SDN from Sandip Lahiri (thank you)

Software Defined Networking (SDN) is an emerging network architecture that reduces cost while increasing quality and service agility over existing networks. Cost includes both capital and operational expenditures. Quality spans network security, robustness, manageability, mobility and flexibility. Service agility allows rapid introduction of new services on the network. (“Why SDN?” offers a good overview.)

A traditional networking device, for example a switch or a router, lumps network control functions together with a data-forwarding mechanism. These components are complex and proprietary, resulting in major shortcomings with the current networking technology. SDN separates these functions with open interfaces. It simplifies networking and lets us innovate.

2013: The Rise of SDN, Death of the “Transaction-Based” User and Customers Bite Back on Vendor Lock-In

The Year 2012 will be remembered for many remarkable events, including the Summer Olympics in London that not only showcased the best in human achievement and global collaboration, but also illustrated how technology-obsessed the world has become. Indeed, more than 4.8 billion people watched the event, with digital viewers outnumbering traditional television viewers for the first time in history.

This single event epitomizes how much society depends on networking technology, and while 2012 was a breakthrough year for broadcasters, enterprises and consumers, what does 2013 hold?

David Meyer, Service Provider business CTO and Chief Scientist at Brocade looks into his crystal ball to outline the top five technology trends we should watch out for in 2013.

How can you make the most out of Software-Defined Networking (SDN)

Post by Alan Murphy (thank you) with a good overview on SDN

Software-Defined Networking (SDN) is a big discussion point in the IT world at the moment, and for good reason. It means no more dealing with individual devices, or manual set up or reconfiguration of switches when they need to be moved or when new locations need to be provisioned with network services. The separation of the control and data planes and the addition of programme interfaces to switches gives unprecedented flexibility to networks and helps to decrease latency. This flexibility and speed is essential for keeping pace with the needs and increasingly high expectations of network users. But if the control plane can gain significant innovation advantages from this separation, what’s happening on the level of the data plane? Is a traditional architecture enough or do we need to rethink it?
