Big buyouts hit the enterprise market, BMC and Bain eye companies

The leveraged buyout of Dell that resulted in its merger with EMC and the computer giant going private was the first of what appears to be many similar moves. Private equity firms are looking to gobble up some of the enterprise giants and in the process, take them private.BMC Software, which develops IT services software and data center automation software, among many other products, is looking to merge with CA, formerly Computer Associates. BMC is owned by Bain Capital and Golden Gate Capital, so any deal to acquire CA would take the company off the public market.To read this article in full or to leave a comment, please click here

Why Do You Still Blog?

After recording an excellent session on social media at Cisco Live with The Network Collective (@NetCollectivePC), I started thinking about blogging and where it stands in the grand scheme of information sharing. With the rise of podcasting and video blogging now in full swing, I was even asked by my friend Michael Stump “Do you see blogging as a dying form of content?” For obvious reasons, I said “no”, but I wanted to explain two major reasons why.

Needle In A Haystack

One of the major reasons why I still blog through written form is searchability. When I started blogging almost seven years ago I wanted to create a place where I could put down my thoughts about topics and share them with everyone. More by accident than design, many of those thoughts became popular topics of conversation. Even today, some of my posts are being used to help people figure out problems and address issues that aren’t well documented in other places.

But why? How can posts many years old still be relevant to audiences today? Because of searching. Use of Google, DuckDuckGo, and even Bing allow people to search for specific error messages Continue reading

Amazon Delivery, Not a Fully Implemented Process

Those of us who work in technology see the need to take expensive, time consuming and/or mundane activities and convert them to streamlined automated processes. Ideally we improve these to the point that they improve accuracy, provide a better experience and can [mostly] be forgotten about. However, not every process fits all of the intended use cases. Maybe a more accurate statement might be that every process isn’t developed to fit every use case. For those of us who are outliers and find ourselves in those process deficiencies, these incomplete processes can create a lot of frustration.

A Little Background

I’ve been an Amazon Prime user for some period of time. I have also been free of a home mailbox for about 18 months and only used a PO Box to receive general mail. As a Prime customer, I regularly place orders with Amazon. Anyone else that has had the experience I’m about to share can probably finish my story.

The Problem

The problem with this scenario is that each order can only have one delivery address. When the order is placed, there is no way to select the delivery mechanism. So if I list my physical home address, I have Continue reading

Worth Reading: Are more specifics harmful?

The number of more specific advertisements in the IPv4 Internet is more than 50% of all advertisements, and the comparable picture in IPv6 has more specific advertisements approaching 40% of all network advertisements. It is tempting to label this use of more specifics as part of the trashing of the Internet commons. Individual networks optimise their position by large-scale advertising of more specifics, which in turn, creates an incremental cost on all other networks in terms of increased BGP table size and increased overhead of processing BGP updates. The question I’d like to look at here is whether these more specific advertisements represent a significant imposition on everyone else, or whether they are simply unavoidable. —APNIC

Comparison: Cisco Catalyst 9500 Vs Cisco Catalyst 4500 Vs Cisco 3850 Switches

Today I am going to talk about the fixed core chassis Cisco catalyst 9500 which Cisco released a month back. Cisco 9500 is actually enhanced version of Cisco catalyst 4500 chassis and also Cisco 3850 Switch. There are lot of other best features in Cisco 9500 Chassis as some of the features are just amazing in this device.

So we have Cisco 3850, Cisco 4500 Catalyst Switches, Cisco 6500 Catalyst switches, Cisco 6800 Catalyst switches and now Cisco 9000 catalyst switches with 3 flavours ( Cisco 9300 catalyst switches, Cisco 9400 catalyst switches and Cisco 9500 Catalyst switches)

How topology and the demand changes, below is the example topology showing the changes which leads to the next generation fabric network with cloud ready solutions and automation. CLI is gone for the campus fabric, All policy is driven with the SDN controller.

Fig 1.1- Network topology and Next Generations

If we have Cisco 4500 and Cisco 3850 fixed chassis why we required Cisco 9500 chassis ?
I knew this is one of the question which you actually thinking and for this i would like to say that you need to understand the next generation campus requirements where customer wants to be Continue reading

Searching for ground truth in IoT

I’ve been reading and writing daily about the Internet of Things (IoT) for about a month, and I have not found ground truth. I’m not new to the field, but now focused on IoT I am trying to find a relative measure of the importance of IoT developments.One of the definitions of ground truth in the Oxford Dictionary is: “Information obtained by direct observation of a real system, as opposed to a model or simulation; a set of data that is considered to be accurate and reliable, and is used to calibrate a model, algorithm, procedure, etc.” Calibrating the development of the IoT with ground truths that match the 20 billion to 50 billion forecasted devices requires a departure into the leap-of-faith lane. This is not pessimism, but a lack of published information that probably does not exist outside of research papers.   To read this article in full or to leave a comment, please click here
