Welcome to my new Green IT blog here at BMC. I have been writing "Adventures in Linux" here since 2005, and will continue to do so, however I have a new role inside BMC as the "Green IT spokesperson", so I added this blog as a way to also be the Green IT writer-person..


I have to admit that it was tempting to call this blog "Adventures in Green IT" but that seemed too derivative...


I do expect it to be an adventure however: Green IT is a pretty broad topic, and covers all sorts of things currently happening in the data center space: Internal and external clouds, IaaS, data center consolidation, virtualization... on and on. All of these are implemented with new technologies, power densities, changes in standards like ASHRAE, and so forth.


Green IT is one of those terms that, like "Cloud" can be interpreted many different ways, depending on where it is approached from, and as I peel back that onion layer by layer, I will be talking about it here. I have also seen that, as I have designed data centers, that standards like ASHRAE have to be interpreted to fit the current situation: I'll be talking about that in an early post.


How did I get here? What do I know about this Green IT thing?


Over my 21+ years here at BMC I have been many things: Mainframe Systems Programmer for VM, Production support, R&D Support, manager of Operations, and various similar roles. In every case I have been involved in the data center: Designing and building them, consolidating them, moving them, upgrading them to new standards, and so forth.


In the monolithic Mainframe days, this was in a way a lot easier. IBM had great physical planning guides, and you could look at them, look at your facility, and pretty much know what you had to do.


These days, and especially in our R&D environment, we have such a mix of vintages, models, manufacturers, systems sizes, virtualized and non-virtualized, SAN and NFS support devices, and all other sorts of heterogeneity that designing and building a data center is far more challenging.


That is of course the fun part. The fun is tempered by the simple notion that "If you can't measure it, you can't manage it". Very BSM'ish, and more than just "a good idea". Really: you don't want to get into designing a data center, with all the captial that involves, and not have a fully square rooted idea of where you are going with it. Not just what it will hold now (I.E. what the CMDB, the single source of truth, holds), but what its limits are, and what it will take to change them if you need to react to future circumstances.


Being green is also more than just about saving power, or making sure all your dead computers are disposed of in the correct manner. There is also the very simple fact that being green can save money. Here in the US, when our money was all green, there was a play on words in there.... in any case, one of my early posts will be about that aspect of it.


It is going to be fun to see how this all develops. I am looking forward to the new challanges of the job, and the new conversations here.
