Data Center Crisis – Part 3 – Getting Dense

first_imgThis is part three – the implication being that it is a sequel to part one and part two. It is. That said, each of the sections have their own messages and may or may not help your data center. The first part talked about the benefits of bringing in the latest hardware. Intel has been delivering performance increases at a pace beyond “Moore’s Law”. Getting rid of old, slow, inefficient servers can give you 2-12 times the capacity instantly. The second “episode” talked about getting everything you can from each server. Use virtualization and consolidation to make sure your servers are full and busy. The most efficient bus is a full bus ( this is a metaphor, I am talking about the big yellow things carrying students, not the circuitry in the box )My focus in part three is on density. My operating premise is that the data center manager wants to get everything out of the current data center and avoid, or at least defer, construction of a new data center. If your in the data center construction business, this is not for you. To get the most out of our data center we want to pack every server we can power into the space. You can do this by executing three actions. 1) Use every watt, 2) Build the right servers, and 3) Optimize HVAC. In many cases twice the servers can be crammed into the existing rack space even without adding power. If you are able to redirect your hvac power savings to your racks, your results could be even better.So, we potentially got 5x capacity from new quad core servers, 5x capacity from boosting utilization with consolidation, and 2x capacity with higher density. My math says 5x * 5x * 2x = 50x the capacity ( in the same space and power!) videolast_img
