About Dirty Cache by Bart Sjerps
At EMC – a company with a history in data storage – we sometimes tend to forget why we are all so busy making great infrastructure solutions for our customers.
This blog is dedicated to the most important parts of the IT environment – the Business Applications – and how they interact with storage infrastructure.
About the name of this blog
In computer engineering, a cache is a component that transparently stores data so that future requests for that data can be served faster.
Dirty Cache refers to data which has not yet been committed to the database (or disk), and is currently held in computer memory. In relation with computer storage, cache is at the borderline between application logic (such as a database) and physical storage components.
In my experience, “Dirty Cache” also is analogue to how the average application often behaves (or often rather misbehaves) on a storage infrastructure.
The name Dirty Cache was vaguely inspired by the song “Dirty Cash (Money Talks)” by Stevie V. in 1990 (watch on Youtube). The song was a protest against materialism and talks about being addicted to money like a junkie.
Sometimes our customers spend lots of (dirty) cash to solve application problems, and I regard it as my (and EMC’s) mission to do more with less – by using intelligent infrastructure rather than throwing more raw computing power at the problem.

I started this blog because I think I can contribute my knowledge and experiences to a larger community than just the few customers I directly talk to as part of my job. I don’t get paid for blogging, but my opinions are probably highly influenced by the fact that I work for EMC.
The opinions expressed here are my personal opinions. I am a blogger who works at EMC, not an EMC blogger. This is my blog, and not EMC’s. Content published here is not read or approved in advance by EMC and does not necessarily reflect the views and opinions of EMC.
