Why are so many still using guesswork to determine their needs for power?

It is 2010 & so many data center & IT managers are still relying on manual derated name plate calculations to manage the power required throughout their power chain even though many of these data centers are on the verge of running out of power & many have experienced outages due to tripped circuits. So many data center & IT managers come to us looking for real-time monitoring of power, many solutions are evaluated, but few ever get implemented. I'm trying to figure out why many are not investing in real-time power management.

If you read the Green Grid's white paper "Proper Sizing of IT Power and Cooling Load" it discusses the fluctuations in IT power draw due to inlet temperature changes, server component changes, virtualization, etc. http://www.thegreengrid.org/en/Global/Content/white-papers/Proper-Sizing-of-IT-Power-and-Cooling-Loads

I don't think we can underestimate the potential danger in using derated nameplate information to calculate power requirements. Unvirtualized servers typically use 15% of the processing power, virtualized we see #'s in the 60-95% range of processing utilization, this directly correlates to #'s closer to nameplate values as the Green Grid pointed out in the white paper. Most IT organizations are rapidly adapting virtualization technology to consolidate and operate more efficiently at the same time, which is a good thing, but it is putting rapid pressure on previously underutilized power infrastructures in data centers.

With so many variables to account for how can one depend on derated calculation tools? With so many real-time tools available to measure & trend power accurately including; branch circuit monitoring, outlet level monitored power strips, in-line power meters, IPMI and extensive software options why are so many still trying to use derated calculations to guesstimate the power they'll need for higher density virtualized deployments? This guesswork leads to potential circuit breaker trips & designed inefficiencies throughout the entire power chain. I am amazed with rising power costs, less power capacity available and so many looking to operate a more efficient "greener" data center footprint that so few are investing in real-time power monitoring tools that will allow them to plan & manage capacity effectively.

What is your definition of a "Green" Data Center solution?

Is your organization looking for "Green" Data Center Solutions or are you looking to incorporate "Green" into your Data Center Design in 2010 or in this decade? Below are some thoughts on this important issue in regards to building "Green" Data Centers. We're interested in hearing your opinions & ideas as well.

For the most part “Green” Solutions for the Data Center, is in my opinion a bit of an oxymoron, because most supposed “Green” solutions still have a carbon footprint & typically use power generated by fossil fuels in the Data Center industry. We also find that rarely are Data Center owners & operators willing to reduce availability to improve the efficiency of their Data Center. That being said, our design philosophy is to design “Greener” Data Center Infrastructure technologies where possible into any proposed new builds, renovations and upgrades for Data Center facilities.

In our opinion the 1st step towards “Greener” Data Centers is collecting accurate measurements & trending the environmentals in your Data Center facilities so we can model proposed changes & fine tune the efficiency. PTS has been running several monitoring & management tools in our own Data Center facility as well as in our clients Data Centers for several years. We use this base knowledge as well as industry best practices & PTS’ proven trade secrets during an engagement for design to propose “Greener” solutions where applicable & in line with the rest of the key design criteria for a project. In our experience many “Green” solutions such as solar & hydro power rarely can make a impact to a Data Center Design, however using water or air side economizers to take advantage of the free cooling days available in an applicable climate can provide a reasonable ROI while “Greening” the Data Center.

In addition by eliminating air mixing in Data Centers, we reduce the power consumed by the HVAC systems supporting a Data Center, and we prove these savings in cooling through CFD modeling before making investments. ASHRAE has widened the temperature range in the new TC9.9 recommendations for Data Center operations, but before we embrace this “Greener” standard and go maximizing the set points for supply & return air; we first must make sure that air mixing has been eliminated as much as possible because as we raise set points, “hot spot” issues & inefficiencies will be amplified, second raising set points reduces the availability of the Data Center so we have to make sure that any proposed increases in set point to make a Data Center “Greener” are in line with the availability requirements established for the Key Design Criteria of a project, third many servers fans will spin faster as the intake temperature rise so there is an inflection point where raising set points further will not continue to lower power consumption.

Focusing on effective Data Center capacity management is key to any "Greening" initiative:
• Better predictability of space, power, and cooling capacity and redundancy limits means more time to plan on ways to mitigate their affect
• Increased real-time availability of IT operations as a result of an enhanced understanding of the present state of the power and cooling infrastructure and environment
• Reduced operating cost from energy usage effectiveness and efficiency as well as operator effectiveness from the use of automated tool sets

In our experience most facility oriented "Greener" solutions provide only a fraction of the efficiency gains found in IT focused solutions such as: server consolidation, virtualization & data deduplication. That's not saying we shouldn't consider the facility oriented "Greener" solutions, especially if they fall in line with our design criteria & ROI needs, but it is saying we should focus on the IT side 1st because of the greater savings & our capacity requirements will be appropriately defined if we become IT efficient first.

‘Lights Out’ Data Center Management

In a recent post at The Data Center Journal, titled “Save some money – work with outsiders,” Rakesh Dogra discusses the new trend to minimize power bills using Lights-Out data center and remote management. [As a side note, way back in 2006 we blogged about how “dim” data center designs are a realistic goal for most companies. You can read that post here.]

Dogra explains that the use of these tactics can lead to major cost savings. He suggests that, looking at your IT, security and facilities staff, it is unwise to cut back on security personnel but it may be prudent to use remote management to replace portions of the IT staff. Additional benefits may include:

• A lesser possibility of accidents and security breaches since fewer people will have physical access to a computer room.
• Response time is boosted with remote bios level access to a data center’s servers.
• Geographical independence can also be achieved through this system.

A potential downside of this system is that a “data center will need people within its premises too to fire fight something going wrong like outages. Also, a data center manager may not find someone with the required amount of experience and expertise to fend off crisis when it happens.”

It is surely a best practice to consider operating as ‘lights out’ a data center as possible, as the author suggests.

For PTS, the real secret to realizing operational costs savings from reduced energy consumption has less to do with facility based solutions than it does with IT. Our position is that there is far more operational cost savings potential coming from virtualizing servers and storage.

To prove the point, in 2010, PTS will perform a network re-design effort of our own operations and provide detailed documentation and analysis of the before and after conditions of our data center energy usage. So, stay tuned...

Intel's Active Management Technology {AMT} provides KVM access & console access eliminating the need for external KVMs or console servers?

There has been a lot of talk in the industry on how Intels new onboard AMT could replace service processors, such as; ILO, DRAC, RSA & ILOM.

http://sof​tware.inte​l.com/en-u​s/blogs/20​09/10/18/i​ntel-kvm-t​his-is-you​r-sol-on-s​teroids/

According to the Blog the local user has to allow the remote user in so I’m not sure this is a valid KVM or ILO replacement as much as a replacement for desktop tools like PCAnywhere & GoToMyPC?

If Intel does have a strategy to lead server remote access & control with AMT, I don't believe it will work. 1st of all, I'd like to point out AMT is an Intel product so it isn't an open standard for a management console. What about those who are buying AMD Opteron processors and/or Sun UltraSparc?

Secondly an open standard for server managment is already well underway from 1998 with IPMI & I think we need to look at what has transpired with IPMI to see what if any support will be given to AMT at the server level. IPMI was originally proposed in 1998 and driven by market leaders Intel, Dell, HP and NEC. Since then IPMI has been adopted by more than 150 other companies, including IBM, Sun, and every major server platform vendor. IPMI is now on its third major release. A significant percentage of rackoptimized servers and most blade computing platforms now include some form of built-in server processor technology that can work with IPMI. Obviously, IPMI data from across the enterprise can only be useful if management teams can view it from a common console. Otherwise, it would offer no advantages over a fragmented, vendor-specific management architecture. Thus, to take full advantage of IPMI, management teams need a solution that 1) delivers aggregated IPMI data to a single application, and 2) supports the IPMI implementations of different vendors.

This second point is critical. While most server vendors include the IPMI protocol in their platforms, they often hide it behind proprietary software/firmware extensions and/or bundled management solutions. An effective server management solution must be able to handle these variations in IPMI implementation in order to provide a unified view into the computing environment. My point is if AMT is to be successful like IPMI the Server OEM's are going to build their own management tools around it to differentiate themselves. Then there will also be 3rd party vendors that build central management tools to centralize access to the different Server OEM's tools that leverage AMT just as there was for IPMI. However, I'm not sure I see all of this happening for AMT because it is proprietary to Intel. IPMI is already included on most systems for these system mangement & diagnostic purposes. The Server OEM's have invested heavily in tools like ILO, DRAC, RSA & ILOM to take advantage of the IPMI chipset. Unlike AMT, IPMI is independent of the CPU and thus independent of a CPU chip failure and can be run on most systems out of band on a separate NIC. Although a few years old. Here is a good whitepaper that covers the development of IPMI and what has occured with its development.
