Power and thermal costs have become an increasingly important component of data center TCO. For some time, Tom Kondo, another Distinguished Technologist, and I have been working on turning NonStop green. We have worked on making sure that you, the customer, get the answers to the following questions:
· I am buying new cooling solutions. How much power will an enclosure really require? It’s always seems to be wired for more than it needs.
· My NonStop systems have low usage or are even idle part of every day or once a week. Is there any way I can save on power during times of low usage?
· Can I see my power and cooling usage in any form?
· What is the history of my power and cooling usage so I can predict the future?
· How can I set the power regulation policies for my data center?
Tom and I worked with many engineers across HP for the last two years with the result that we now have several recently released power management features shipping on NonStop that you may not be aware of.
So, you've built your data center, put in redundant power feeds, and loaded it with systems and storage? What could possibly go wrong from a power and cooling perspective? I've spoken with customers and some of our internal HP engineers, and they've regularly seen a common problem that prevents redundant power set ups from providing system level protection - a big problem, especially for mission critical systems. HP has something that could help you diagnose and prevent this problem in your data center.
I had a chance to spend some time with a customer yesterday talking about how HP runs its internal IT operations, industry best practices, trends and more.
One of the interesting comments from the customer was that they were running all there servers at high performance or maximum power levels all the time, even though he knew that average utilization was 40% or less even with virtualization. He also said that he was worried about the risk of reducing processor power and potentially impacting server performance, something that was echoed by studies that I mentioned in a blog post late last year.
One of his requests was a practical way to start implementing power management in a non-intrusive, quick and easy way. He hadn't seen anything that provided that level of detail. Since he primarily had HP BladeSystem for his compute infrastructure, we figured that it made sense to implement HP Power Regulator dynamic power mode on his blades via the iLO 3 cards.
