Introduction to Multi-chassis EtherChannel(MEC) in Cisco Switches
Today I am going to talk about the technology used in the enterprise or the datacenter environment for various vendors in the market. Starting from the Multi-chassis EtherChannel (MEC), Multi-chassis EtherChannel is generally used in the Cisco technology with the VSS.
Before I start with the Multichassis EtherChannel, I would like to tell you guys that we have our own youtube channel for various network videos that can further help you guys to study further. I will going to add many more videos soon on the channel, Please subscribe to the channel for the study network related videos.

Multi-Chassis EtherChannel
Multi-chassis EtherChannel (MEC) is a Layer 2 multipathing technology. This form of EtherChannel allows a connected node to terminate the EtherChannel across the two physical Cisco Catalyst 6500/6800 Series Switches that make up the VSS leading to creating simplified loop-free Layer 2 topology.
Cisco’s Multi-chassis EtherChannel (MCEC) solution addresses the need for inter-chassis redundancy mechanisms, where a carrier wants to “dual home” a device to two upstream points of attachment (PoAs) for redundancy

Terminology Tuesday Presents: Data Gravity
Data Gravity is a concept first coined by Dave McCrory to describe the tendency of data to attract more data, applications and services. As you may have guessed from the name, this principle has many parallels to Newton’s Theory of Universal Gravitation.
The basic premise is that a singular piece of data isn’t meaningful but with more data (metadata as it’s generally called) additional context (and therefore more meaning) can be derived. When all that data is bundled with more applications and services, one can harness a considerable amount of power as evidenced by today’s trends towards data and analytics.
For example, let’s take this piece of data: 0. Although we know what zero means conceptually, we don’t have any way to determine how we should feel about it. Without any context just knowing the number 0 is essentially worthless. If, for instance you were to know the additional data of “inventory of toy Elmos” + [insert where you live] you’d know that you need to make an only order and ASAP.
Data for larger institutions is just like this, except the concept of “friction” plays a larger role. Data Friction Continue reading
A Guide to Open Source for IT Practitioners
It’s easy to see that open source is changing the way people think about infrastructure. However, as the saying goes: “The future is here, it’s just not evenly distributed”. As is normal, there will always be pockets of IT where active involvement in open source will just take some more time.
I’ve worked on open source for a few years now, and I have always wanted to publish a post that focuses on a few key ideas that I wish I could tell every new entrant into the world of open source. I feel like going in with the right expectations can really help any efforts here go much more smoothly. So if you’re accustomed to getting most if not all of your technology stack from a vendor, and you’re wondering about the open source craze, and trying to make sense of it all, this is for you. My goal with this post is to empower you to start getting out there and exploring the various communities behind the projects you may already have your eyes on.
