Energy Star partner logoENERGY STAR® Program Requirements for Computer Servers (pdf) version 1.0 have been released on May 2009. This document’s scope includes only Tier 1 servers, from 1 to 4 processors . Applicable in October 2010, Tier 2 will include systems with greater than four sockets, Blade Systems, Fully Fault Tolerant Servers, Server Appliances, and Multi-Node Servers (more than two node in the same enclosure). Storage and network equipment are explicitly excluded and will be covered by extra specifications, although Ethernet efficiency will be included in Tier2 specifications (page 13).

The requirements focus on the following points :

  • PSU efficiency (page 9),
  • Power Management – idle power (page 10) dependant of the number of sockets and configurations (an extra PSU is 20 W, a hard disk is 8 W, etc.)
  • Information presentation through a standardized data sheet (page 11 – sample from HP (pdf) and Dell (pdf)). This will become easier to  compare during purchasing process.
  • Data Measurement and Output on power, processor usage and inlet air temp (page 12). This one applies only if the server qualifies for the “Managed Server” category or has more than 2 cpu sockets. It leaves up to the manufacturer the way to measure (service processor, embedded power or thermal meter). The good part is that:

    Data must be made available in a published or user accessible format so as to be readable by third-party, non-proprietary management system.

Testing criteria are also mentioned at the end of the document.

Two manufacturers have released compliant hardware but note that Dell does not appear on the ENERGY STAR Computer Server Qualified Product List (pdf) from June, 1 2009:

This list will surely be extended soon…

NYT : Data Center Overload: Great New York Times article coming with a slideshow on datacenter evolution, from the wtf? to usage, cost and strategy/impact for industry (Karl Marx involved).  For any architect, the “Latency concerns are not limited to Wall Street; it is estimated that a 100-millisecond delay reduces Amazon’s sales by 1 percent.” is priceless.

When upgrading to Wordpress 2.8 (or any version), the Codex Troubleshouting FAQ is a must have. I felt aventurous and tried an auto – upgrading to wordpress 2.8. Two questions minimum applied to me as I had to remove the .maintenance and re-upload all files to the directory for obscure reason… oh, wait, that’s a manul upgrade.

Jülich Supercomputing Center (JSC)’s Clustercomputer JUROPA: Sun’s Marc Hamilton has a series of posts (1, 2, 3)on the  where Sun is providing two systems : Constellation high performance computing and Lustre storage system. Architecture is presented and pictured into details up to cabling and cooling.
NASA’s Nebula (Sun Lustre used for storage) is worth a look as well.
Nevertheless, the story does not tell if it’s green or not.

Cisco’s blog post A More Granular Approach To DC Cooling, is mentioning two tools:

Data Center Assurance Program: Behind the wording, are standing very useful and strong documents like the DCAP System Assurance Guide 4.0 (PDF – 21 MB) and some Datacenter designs guides:

Depending of your needs, these documents can be too technical or too application oriented (solution for one vendor). I haven’t find Unified Computing System related content there.

Second, the Cisco Power Calculator (requires CCO login) enables sizing and checking PoE configurations.

Symantec 2009 Green IT Report (pdf)Symantec 2009 Green IT Report (pdf) has been published today and is 23 pages of fast reading. Scope is somehow ridiculous in Europe where all northern countries like Germany and Scandinavia were not included in the research scope whereas they are leaders on a lot of environmental and green initiatives in this region. Note that if you want to dive into graph’s details, you will need very good eyes due to compression.

It does not contain very valuable information if you already agree that yes Green IT is important (at least in your strategy and purchasing). It success is limited to interest in reducing running cost  and not really going further (reducing carbon emissions is third interests). That’s good to start with something, but this is only going back to a regular, lean situation where we should have been since the beginning.

I would love to see the question asked for some points:

page 8:

When asked how important a product’s energy efficiency would be in purchasing decisions over the next 12 months, 91 percent said it was important/very important. Only one percent believed that it would be unimportant.

I think they were referring to hardware purchasing and TCO. Even so, we already discuss on the necessary metrics to define efficiency in IT, embrassing both hardware and software world.

page 6:

Additionally, 92 percent of companies said they were somewhat/significantly interested in purchasing energy efficient hardware, followed by re-laying out the data center for more effective cooling and energy consumption (84 percent) and exploring alternative ways to generate power, such as solar/wind (70 percent).

page 10:

Companies are searching for the best ways to go about achieving their desire for green data centers. At the top of the list is an attempt to replace old equipment with newer, more efficient hardware (96 percent). Close behind are monitoring power consumption (94 percent), server consolidation (94 percent) and server virtualization (93 percent).

The hierarchy is clear again: server hardware will be changed for better one, achieving both green objectives and technological/renewal investment in one shot (in that case, it is not a green project, it is green washing). Long term investments, real projects, like for facilities and energy production will wait. The error comes from the point of view : hardware is not only the solution, software via control and measurement provides a lot of solutions. It is maybe the financial context that drives short term decisions and investments but I am wondering how many companies have a full GreenIT plan, containing both facilities and energy sources. The siloed organizations are producing siloed initiatives.  Having a study on collaborative, “Entreprise 2.0″ companies and their green initiatives would have some interests, especially for their scopes.

The good news is there:

page 9:

Finally, 81 percent of companies surveyed have a green advocate in charge of coordinating all green activities. Of those, most have an IT focus.

Installing Ubuntu LTS for a LAMP in VMware Workstation: Nothing new, I just needed to have this under the hand.

centreonCentreon is a web interface for Nagios, adding graphing, reporting and monitoring features.  I added a tutorial that describe its installation (version 2.0.2 for Nagios 3.0.6).

Purpose was to compare open source solutions based on Nagios. I wish they had a WMware Virtual Appliance like Groundwork’s one so this tutorial tries to ease the installation process.

VMware Tools Installation Guide Operating System Specific Packages: note to myself. I am following the traditional way of vmware-install.pl and haven’t tried yet that. It seems longer but safer using packages made by VMware that you don’t have to compile yourself.

How a Good Metric Could Drive Bad Behaviors:  through three issues commonly reported, this post pictured one more time the limitations of The Green Grid’s PUE and the need to make it a real metric : something easily measureable, with an expressed unit (it is actually a ratio more than a metric without it).  I already discussed that but it is always good to repeat. The Green Grid is working on guidelines and improvements, through the “proxies“.
