Data centers electricity consumption-Amazing facts

Data centers electricity consumption-Amazing facts from AMD


AMD has released some amazing data center facts- servers,data center infrastructure and cooling infrastructure consumed around 1.2% of the electricity consumption of the entire US market


Alternatives to lowering electricity consumption in data centers


Data centers need to seriously look at data center options such as server consolidation and virtualization, in the aim to use data center server CPU as a service


  • Data center server consolidation:In a survey of data centers across the US, I can state with confidence that 80% of servers are operating at below 20% capacity. Data center server consolidation will not only save money for data centers in server cost but also help in reducing precious energy resources such as electricity consumption

  • Data storage server virtualization:Data storage server virtualization assists data centers in optimally switching between blade servers to create a true CPU and data storage as a service data center. This server virtualization will also mean that optimal electricity consumption is taking place in the data center

Google publishes hard drive expose!

Hard drive expose by Google-A hard drive white paper study from Google


Google has published a document on hard drive failure rates based on the study of hard drives at Google's data centers


Google's hard drive study makes for very interesting reading-and cannot be taken lightly since the sample size of Google's data centers is very huge


Google's hard drive collapse surprise finding 1:Hard drive failure not correlated highly with temperature


Google's hard drive failure study finds that there is no one on one correlation of temperatures with hard drive failure


Per Google's hard drive research,new hard drives prefer higher temperatures and older hard drives prefer lower temperatures and are susceptible to reverse temperatures


Google's hard drive research is in short suggesting that we shouldn't assume that all drives are equally susceptible to manufacturers


Google uses cheap and a variety hard drives from various manufacturers


Google operates one of the largest data centers in the world, and amazingly uses cheap hard drives with a combination of serial and parallel hard disk drives, with speeds from 5400 to 7200 rpm.


Incredible, that Google's large data centers uses hard drives that may be obsolete elsewhere


Google's hard drive research suggests that SMART hard drive parameters are not the only symptoms that aid in preventing hard drive failures


Firstly,Google extensive use of SMART hard drives (self-monitoring drives) is interesting


Further,Google's conclusion about SMART hard drives is a signal to SMART drive manufacturers that the data monitored is not good enough


Google's hard drive research summary


Get rid of hard drives after the

  • Hard drive first scan error

  • First hard drive sector reallocation error

  • The first hard drive probational count error

Disaster recovery-Should disaster recovery centers be local or geographically dispersed?

Should disaster recovery center be local or geographically dispersed


Disaster recovery centers are typically near shore-close to the geographic region where the core operations data centers are located.

Is this near-shore disaster recovery location a good idea?


Disaster recovery centers at near shore locations to data centers have the disadvantage of being used for actual data center operations as a supplementary data center site


The typical data center scenario: More and more normal operations data center stuff gets pushed to the disaster recovery data center and as a result, the disaster recovery data center begins to resemble a supplementary data center

Disaster recovery disaster-This supplementary data center scenario defeats the very purpose of having a separate disaster recovery data center
