Measuring Real-World Power Consumption, Part 2

For our second real-world power test, we turn to our "proprietary" virtualization benchmark vApus Mark II EWL. We'll see if this VMware + Windows 2008 combination produces similar results to vApus FOS EWL. You can find out more details about vApus Mark II EWL here. This workload uses several IIS web sites and MS SQL Server 2008 server. First we'll check performance.

vApus Mark II EWL performance

Interestingly, Hyper-Threading does make a difference here: we get about 10% higher performance. When we zoom in on our results, we see that especially the MS SQL VMs perform better with Hyper-Threading: we see an 18% performance boost. The Open Compute server performs again slighly better than the HP.

vApus Mark II EWL Energy Consumption

The HP server needs 12% more power to deliver the same performance. The Open Compute server once again delivers superior performance/watt.

    In the middle of the paragraph below the image caption, the sentence reads "...and offers better slightly better performance..."

    Other than that, nice post!

    It's interesting that no many players have taken a look at Open Compute. Reply

    it's a solution for a specific workload. there are still a lot of workloads that require the traditional model of big database servers

    unlike your bank, facebook's noSQL is not ACID

    Well, yes a voice of reason. OTOH, the Facebook et al folks are convinced that their back to the COBOL era is the future. As if a toy application, albeit pervasive, is "innovation". Reply

    It's a little difficult to look at a comment about Facebook being a toy application and take it seriously. Yes, Facebook is not directly processing bank transactions on a Tandem, but their site is used to conduct business -- and is even the basis for many businesses, all over the world.

    Zynga, the company that makes a few annoying games for Facebook, is worth $15 -- more than Electronic Arts.

    Nearly every major online publisher, including Anandtech, uses their API for content distribution and often as the entire forum system for discussion of publications.

    The founder is the youngest billionaire in history.

    Calling theirs a toy application sounds like a Blockbuster customer calling Redbox a toy. It's denial of an obviously successful, large, powerful, innovative company because they don't do things "the old way."

    I suspect what matters more is that the business is executing flawlessly, the actual problems with data loss or other non-ACID compliant traditional issues are minimal, and that they are making enough money that Google and Microsoft are feel seriously threatened.

    One last thing -- if you really look into what ACID compliance means (and I know you did not specifically mention the acronymn, but replied to someone that did) none of the current major DBMS's are truly ACID compliant. It's too slow. Not Oracle. Not MSSQL. Not Greenplum. Not Teradata. None of them. They may be closer than NoSQL or the like, but then it's all about the right tool for the job, right?

    This is true but ACID can be over-rated for many workloads. How many pieces of data HAVE to be consistent across the entire cluster to be valid? What about NoSQL with configurable consistency like Cassandra?

    NoSQL databases provide the holy grail of system growth which is horizontal scaling and this is no small thing for anyone who has worked with a very large RDBMS like ORACLE and implemented RAC to find it doesn't scale all that linearly for most workloads.

    Wouldn't the presence of the graphics on the HP server account for the 32W idle load savings? Reply

    It is an ATI ES 1000, that is a server/thin client chip. That chip is only 2D. I can not find the power specs, but considering that the chip does not even need a heatsink, I think this chip consumes maybe 1W in idle. Reply

    ES 1000 is almost the same as radeon 7000/ve (no that's not HD 7000...) (some time in the past you could even force 3d in linux with the open-source driver though it usually did not work). The chip also has dedicated ram chip (though only 16bit wide memory interface) and I'm not sure how good the powersaving methods of it are (probably not downclocking but supporting clock gating) - not sure if it fits into 1W at idle (but certainly shouldn't be much more).

    I can not find any good tech resources on the chip, but I can imagine that AMD/ATI have shrunk the chip since it's appearance in 2005. If not, and the chip does consume quite a bit, it is a bit disappointing that server vendors still use it as the videochip is used very rarely. You don't need a videochip for RDP for example. Reply
