Cut Your Data Center Cooling Costs

Modern data centers face a number of cooling system challenges due to the requirements of today's IT systems, combined with the way those IT systems are deployed. In the latest issue of PROCESSOR magazine, Elizabeth Millard examines strategies for keeping power and cooling operations streamlined during the summer months when outside temperatures rise.

The article includes my thoughts on the topic, as well as insights from John Busch, chairman and CTO at Schooner Information Technology; Michael Sigourney, senior product specialist at AVTECH; and Kris Domich, principal consultant at Dimension Data.

Key points include:

• Look at upgrading processing and storage capability for greater efficiency.
• Establish a strong preventive maintenance strategy before the summer months hit.
• Keep accurate records to understand utilization and cost changes over different years.

PTS' expertise is a valuable asset in this area as companies are often unable to predict if their data center cooling system will supply a future load, even when the characteristics of the load are known in advance. If your company is looking to establish a cooling system for your data center that will withstand system failures and load increases, contact PTS as the next step in your process.

Considerations for Storage Consolidation

The growth of company files, e-mail, databases, and application data drives a constant need for more storage. But with many networks architected with storage directly attached to servers, growth means burdensome storage management and decreased asset utilization. Storage resources remain trapped behind individual servers, impeding data availability.

There are three storage consolidation architectures in common use today:

• direct-attached storage (DAS),
• network-attached storage (NAS), and
• the storage area network (SAN).

DAS structures are traditional in which storage is tied directly to a server and only accessible at that server. In NAS, the hard drive that stores the data has its own network address. Files can be stored and retrieved rapidly because they do not compete with other computers for processor resources. The SAN is the most sophisticated architecture, and usually employs Fibre Channel technology, although iSCSI-based technology SANs are becoming more popular due to their cost effectiveness. SANs are noted for high throughput and their ability to provide centralized storage for numerous subscribers over a large geographic area. SANs support data sharing and data migration among servers.

So how do you choose between NAS, RAID and SAN architectures for Storage Consolidation? Once a particular approach has been decided, how do you decide which vendor solutions to consider? There are a number of factors involved in making a qualified decision including near and long term requirements, type of environment, data structures, budget, to name a few. PTS approaches Storage Consolidation by leveraging our proven consulting approach:

• to gather information on client needs,
• survey the current storage approach, and
• assess future requirements against their needs and the current approach.

Critical areas for review and analysis include:

• Ease of current data storage management
• Time spent modifying disk space size at the server level
• Storage capacity requirements to meet long term needs
• Recoverability expectations in terms of Recovery Time Objectives and Recovery Point Objectives
• Needed structuring of near- and off-line storage for survivability and ease of access to data
• Security needed to maintain data storage integrity
• Evolving storage complexity if current architecture is maintained
• New applications considered for deployment
• Requirement to provide Windows clustering
• Interest in considering Thin Provisioning
• Storage spending as a percentage of total IT budget

PTS reviews all of the items above, and more --- we then design the best storage architecture for both near and long term requirements and are able to source, install and manage leading edge storage solutions from companies such as Dell and Hitachi.

Ultimately, Storage Consolidation positively impacts costs associated with managing your IT network in terms of redundancy, disaster recovery, and network management. It also allows for a more secure network, free from wasted assets tied to particular servers or data center components. Finally, the tasks of provisioning, monitoring, reporting, and delivering the right storage services levels can be time consuming and complex and Storage Consolidation will enhance your ability to manage your organization's data storage.

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...
