There’s no 1-tier network… Do you have a problem with that?

I’m not a car person and I don’t worry too much about what’s under the hood. That means that I’m just a car user, I only want to turn the ignition key and drive. In the Data Center world, the server team is typically a user of the network. Server guys don’t want to know how the network is implemented. They just want their VLANs to extend to the whole network so that they can connect their devices with no constraint, without having to worry about high availability, risk containment, link provisioning… network stuff. That’s precisely what FabricPath is designed to offer them: a network that looks like a single switch, the simplest networking entity. This “Fabric” offers efficient any-to-any connectivity with high bandwidth and low latency, all without having to understand how it works.

User view, a single switch

Of course, this user perspective is an abstraction. The following Figure 2 represents an example of the physical topology of the network, a Clos fabric, typical in Data Center environments. Note that this could just as well be a ring, a star, or even a network distributed across two sites. FabricPath turns an arbitrary topology into a Fabric and does not lock you into a particular model.

Is the new data center fabric really a combination of Borg and big Brother? Answer on March 30th

I don’t know about you , but I want to be well prepared for the March 30th Cisco announcement
Listening to Cisco SVP Bill Brownell’s invitation, we can definitely expect some very interesting product news, but more importantly a new round of conversations about the right fabric-infrastructure, especially in the context of cloud computing.

That’s why we will have special guests such as John McCool, Soni Jiandani and Tim Gillis in addition of Forrester Research and IDC (see my previous blog)

So as I was willing to be well prepared, I found this interesting blog from Ivan about data center fabric architecture , which obviously grabbed also the attention of some of our smart  engineers
