THERE IS A SAYING:
Faster, Better, Cheaper pick any two!”
The implication being that it’s not possible to deliver all three together.
This defeatist attitude probably often stops people from even attempting to try, knowing that others that have gone before have failed. On individual tasks or products, this saying might possibly be true.However, when we extend our scope, not only do I strongly believe that achieving all three is possible, I actually know it’s possible having achieved it, not only once, but on several occasions.
At the start of the task I was told that the Data Center was running at an optimum level and that the only way we could improve was to invest. Prior to agreeing to the extension of the data center I asked for a report showing the utilization of our servers, of which we had over 4000.
I was provided with a report, which at a summary level, showed that the overall performance was in line with industry best practice. Whilst I didn’t doubt the accuracy of the report, I felt that it didn’t give the full story, so I asked for a more detailed report that showed the % utilization of each server. What I saw when I received that report was, that we had around 500 servers who’s utilization was close to zero percent. When I questioned this, I was told these were back up/failover servers and it was normal that they would have very low utilization, i.e. <1%.
I wasn’t completely convinced, so I asked for even more details, asking which applications these servers were supporting. Once this report was prepared, it showed that over 450 servers, just over 10% of our total inventory, had zero utilization and were not being used to support any applications at all. These were orphan servers, which were a result of several mergers and acquisitions, which had just been forgotten about. Given that they were never-failing they were just left idle.
We set up a program to decommission these servers, which netted us a saving of over $5m. Additionally, with this reduction of required capacity we were also able to cancel the extension of the data center that avoided additional costs of over $2m. At this point, we had now achieved one of our three goals of Faster, Better and Cheaper.
What we did next was to invest some of the savings to fund projects to:
- Virtualize servers
- Migrate some of the systems from Unix to Linux
- Reviewed the backups/failover systems that some were not correctly set up
- Implemented Oracle Clustering onto additional systems
- Reallocated some of the zero utilized servers to other applications to increase their performance.
As we moved through these optimization projects many staff came forward with additional recommendations where we could eliminate waste/unused resources. Overall we were able to cut the Operations budget by $20m per annum, and improved operational performance and reliability.
Faster, Better and Cheaper is achievable!
