Data Center War Stories talks to SAP’s Jürgen Burkhardt

And we’re back this week with the second installment in our Data Center War Stories series (sponsored by Sentilla).

This second episode in the series is with Jürgen Burkhardt, Senior Director of Data Center Operations, at SAP‘s HQ in Walldorf, Germany. I love his reference to “the purple server” (watch the video, or see the transcript below!).

Here’s a transcript of our conversation:

Tom Raftery: Hi everyone welcome to GreenMonk TV. Today we are doing a special series called the DataCenter War Stories. This series is sponsored Sentilla and with me today I have Jürgen Burkhardt. Jürgen if I remember correctly your title is Director of DataCenter Operations for SAP is that correct?

Jürgen Burkhardt: Close. Since I am 45, I am Senior Director of DataCenter Operations yes.

Tom Raftery: So Jürgen can you give us some kind of size of the scale and function of your DataCenter?

Jürgen Burkhardt: All together we have nearly 10,000 square meters raised floor. We are running 18,000 physical servers and now more than 25,000 virtual servers out of this location. The main purpose is first of all to run the production systems of SAP. The usual stuff FI, BW, CRM et cetera, they are all support systems, so if you have ABAP on to the SAP in marketplace, you, our service marketplace, this system is running here in Waldorf Rot, whatever you see from sap.com is running here to a main extent. We are running the majority of all development systems here and all training — the majority of demo and consulting system worldwide at SAP.

We have more than 20 megawatt of computing power here. I mentioned the 10,000 square meters raised floor. We have 15 — more than 15 petabyte of usable central storage, back up volume of 350 terabyte a day and more than 13,000 terabyte in our back up library.

Tom Raftery: Can you tell me what are the top issues you come across day to day in running your DataCenter, what are the big ticket items?

Jürgen Burkhardt: So one of the biggest problems we clearly have is the topic of asset management and the whole logistic process. If you have so many new servers coming in, you clearly need very, very sophisticated process, which allows you to find what we call the Purple Server, where is it, where is the special server? What kind of — what it is used for? Who owns it? How long is it already used? Do we still need it and all that kind of questions is very important for us.

And this is also very important from an infrastructure perspective, so we have so many stuff out there, if we start moving servers between locations or if we try to consolidate racks, server rooms and whatsoever, it’s absolutely required for us to know exactly where something is, who owns it, what it is used for etcetera, etcetera. And this is really one of our major challenges we have currently.

Tom Raftery: Are there any particular stories that come to mind, things issues that you’ve hit on and you’ve had to scratch your head and you’ve resolved them, that you want to talk about?

Sentilla thinks of data centers, as data factories!

Data center
If you have been following this blog, you’ll know I have been profiling Data Center efficiency companies over the last few weeks. This week I take a look at Sentilla.

I talked to Sentilla’s CTO and co-founder, Joe Polastre, the other day and Joe told me that Sentilla came out of Berkeley where they had been looking at data analytics problems around large, potentially incomplete or inaccurate, streaming datasets. The challenge was how to turn that into a complete picture of what’s going on so people could make business decisions.

Sentilla takes an industrial manufacturing approach to Data Centers – in manufacturing you have power going in one side, and products and (often) waste heat coming out the other. In the same way in data centers you have power going in one side and coming out the other side you have the product (compute cycles) and waste heat. To optimise your data center you need to get the maximum data/compute (product) output with the minimum power in and the least waste heat generated. Sentilla thinks of data centers, as data factories!

Unlike most of the data center people I have talked to, Sentilla don’t talk so much about energy savings. Instead they emphasise maximising performance – getting the most out of your existing data centers, your existing storage, your existing servers, your existing power supply. By far the greatest saving from deploying Sentilla, Joe claimed, is not from the energy savings. That pales in comparison to the capital deferment savings gained from being able to delay the building of extra data center facilities by however many years, he said.

So how does Sentilla help?

Well Sentilla analyses the energy profile of every asset in the data center, whether metered or not, and makes recommendations to improve the planning and management of data center operations…

My “Green IT – driving efficiency, sustainability and enabling efficient working practices” presentation
Green IT – driving efficiency, sustainability and enabling efficient working practices

Conference organising company iQuest contacted me last year to ask me to deliver a keynote presentation at their Green IT Summit.

The event took place in Dublin yesterday and my keynote talk entitled “Green IT – driving efficiency, sustainability and enabling efficient working practices” is above.

The organisers prudently decided that they didn’t want to take the risk of any of their international speakers not making it to the event because of the ashcloud. This would have left them with a hole in the schedule at the last minute so they contracted the services of OnlineMeetingRooms and three of the presenters were able to present to the audience in Dublin, over an online video connection, without having to travel!

The title I was asked to present on was quite broad and I had 30 minutes to try cover it all so I had to go at quite a clip but the feedback has been extremely positive so it seemed to work out very well.

Up is down, black is white, Microsoft does Linux deal with Novell!

From the “They said it would never happen dept” comes news today that Microsoft have signed a deal with Novell!

The deal has been summarised into three main points by Dana Gardner:

  1. Under a technical cooperation agreement, Novell and Microsoft will work together in three primary areas to deliver new solutions to customers: virtualization, web services management and document format compatibility.
  2. Under a patent cooperation agreement, Microsoft and Novell provide patent coverage for their respective customers, giving customers peace of mind regarding intellectual property issues.
  3. Under a business cooperation agreement, Novell and Microsoft are committing to dedicate marketing and sales resources to promote joint solutions.

The timing of this deal is curious, coming as it does only a few short days after Oracle announces its enhanced support for Linux!

Looks like a competition to see who can love Linux the most these days, doesn’t it?
