DEWWe just concluded a massive week of technology launches, media briefings, customer meetings and world class thought leadership in Las Vegas at Dell EMC World. Having been to many EMC Worlds, this event was bigger, badder (in a good way) and more fun than anything I have seen before. Here are my top 10 highlights:

10. The products launches were on a scale unheard of. If you went to the event expecting one product update, or a few feature enhancements then you would have been blown away by how almost every product line was enhanced, and the innovation didn’t just stop at technology. It included innovations and launched in= solutions, services and new consumption models. We announced new platforms around Azure stack (hybrid cloud to extend out to Azure).

There has been a lot of talk about disruption in 2015. A big theme in 2016 will be the disruption of the IT professional. Every role in IT will change and the pace at which we learn new concepts, skills and models will be important for success for anyone in IT. This post should help you get your head around some of the changes coming.

Let me start by saying that the ideas discussed here are my own, and not necessarily that of my employer (EMC). This is my own personal blog.

A great article by Andrew Oliver has been doing the rounds called “Never ever do this to Hadoop”. Andrew argues that the best architecture for Hadoop is not external shared storage, but rather direct attached storage (DAS). The article can be found here:–ever-do-this-to-hadoop.html

I want to present a counter argument to this. Now having seen what a lot of companies are doing in this space, let me just say that Andrew’s ideas are spot on, but only applicable to traditional SAN and NAS platforms. There is a new next generation storage architecture that is taking the Hadoop world by storm (pardon the pun!). EMC has done something very different which is to embed the Hadoop filsyetem (HDFS) into the Isilon platform. This approach changes every part of the Hadoop design equation.

Ok, here is an issue I have been struggling with for a while and finally came across a fix. When installing Pivotal Cloud Foundry for a second or third time, often the installation will drop out on the step “creating director user” with the following error:

Target already set to `microbosh-b5f7fa48777480cf307e’ {“type”: “step_finished”, “id”: “microbosh.logging_into_director”} {“type”: “step_started”, “id”: “microbosh.creating_director_user”}

Pivotal CF Issue 2

If you encounter this issue while Installing Pivotal CF then here is a potential fix. A web search showed no public fix to this so this might help others and the fix is fairly simple. The exact error I received is below and this occurred while installing Pivotal Cloud Foundry v1.2.2. on ESX 5.5.

`block in wait_for_task’: The operation is not allowed in the current connection state of the host. (RuntimeError)

Now that you have built your app we need to add a database. Use the following command to see what services you can create:

> cf marketplace

You should see something like this.
