U.S. EPA Energy Star Wants and Needs You!

Here’s the message received from the EPA via their mailing list this past week (in italics below):

Dear Enterprise Storage Equipment Manufacturers and Other Interested Parties:

Please see the attached letter from the U.S. Environmental Protection Agency (EPA) announcing their intent to pursue development of an ENERGY STAR specification for Enterprise Storage equipment.  If you have any questions or concerns, please contact Andrew Fanara, EPA, at fanara.andrew@epa.gov or Stephen Pantano, ICF International, at spantano@icfi.com.

Thank you for your support of ENERGY STAR.

Here’s the intro letter excerpted from the above email notification (in italics below):

April 23, 2009

Dear Enterprise Storage Equipment Manufacturers and Other Interested Parties:

This letter is intended to inform all stakeholders that the U.S. Environmental Protection Agency (EPA) intends to continue its efforts towards the development of an ENERGY STAR® specification for enterprise data storage equipment. Following is an outline of EPA’s general goals and next steps.


ENERGY STAR is a voluntary partnership between government, businesses, and purchasers designed to encourage the manufacture, purchase, and use of efficient products to help protect the environment. Products that earn the ENERGY STAR prevent greenhouse gas emissions by meeting strict energy efficiency guidelines. Manufacturers that qualify their products to meet ENERGY STAR requirements may use the label as a tool to educate their customers about the enhanced value of these products.

To date:
•More than 2,000 manufacturers are partnering with ENERGY STAR,
•More than 40,000 product models carry the ENERGY STAR label across more than 50 product categories,
•More than 70% of Americans recognize the ENERGY STAR label,
•Consumers have purchased more than 2.5 billion ENERGY STAR qualified products, and
•Americans, with the help of ENERGY STAR, saved enough energy in 2008 to avoid greenhouse gas emissions equivalent to those from 29 million cars — while saving $19 billion on utility bills.

In the last several years, the energy saving opportunities in data centers have been well documented. However, barriers to energy efficiency still persist and need to be addressed. EPA is pursuing a dual strategy to overcome these challenges by helping purchasers more easily identify energy efficient IT equipment with the use of the ENERGY STAR designation, and by encouraging organizations to benchmark the energy performance of their data centers.


In pursuit of this strategy, EPA will introduce an ENERGY STAR Computer Server specification in the coming weeks. In addition, EPA recently conducted a scoping effort to evaluate enterprise storage products for inclusion in the ENERGY STAR program. EPA reviewed available market research and facilitated discussions with product manufacturers, industry associations, and other interested parties. EPA concluded that IT purchasers would benefit from access to standardized information about the energy performance of storage equipment made available through the ENERGY STAR program. As a result, EPA intends to begin the specification development process. Details on this process will be forthcoming in the next several weeks.

To be added to the enterprise storage e-mail distribution list, please send your full contact information to Stephen Pantano at spantano@icfi.com. To stay informed about the ENERGY STAR specification development process for computer servers and other EPA data center initiatives please visit: www.energystar.gov/datacenters.


Thank you for your continued support of ENERGY STAR and please direct additional questions to Andrew Fanara at fanara.andrew@epa.gov or Stephen Pantano of ICF International, at spantano@icfi.com.

Sincerely,

Andrew Fanara
U.S. Environmental Protection Agency, Climate Protection Partnerships Division ENERGY STAR Program Manager

My take on the Energy Star programs is that as long as they add value including reflecting how energy is effectively used both when IT equipment such as servers and storage are in use, as well as in energy saving or avoidance modes are reflected, they can and should be a good thing.

However industry will need to work together across different trade and focus groups as well as factor in how supporting metrics will be applicable and reflective thus accepted by IT data center environments. This means metrics and measurements for both active or working while in use energy efficiency modes such as IOPS, bandwidth, messages or transactions, files or videos per watt of energy, as well as metrics for in-active or dormant data such as capacity per watt per usable footprint. Check out Chapter 5 (Measurements and Metrics) in "The Green and Virtual Data Center" (CRC) to learn more.

Various industry trade and focus groups including Storage Performance Council (SPC), SNIA GSI, Green Grid, SPEC and others are working on various metrics and aligning themselves to work with EPA. If you are in an IT data center involved with servers or storage, consider getting involved with one or more of these groups to help influence and shape what these programs will look like or affect your organization in the future.

Happy Earth Day 2009

Its that time of the year again, that’s right, earth day April 22 2009!

If you frequent this blog, visit my websites (StorageIO, The Green and Virtual Data Center or Green Data Storage), track twitter, attended any of my speaking engagements, webcast, podcast, videos, radio interviews, seen press or media coverage, not to mention read any of my reports, articles, tips or books, it should not come as a surprise that I have something to say about Green IT and closing the Green Gap.

The Green and Virtual Data Center (CRC)

Common themes have included awareness of the green gap and how to address or close it including discussions around IT transformation, infrastructure optimization, boosting productivity and efficiency to support business sustainability among others. While its tempting to go on and on about different trends, topics, techniques, technologies and related themes with a back drop of earth day, lets leave it at this for now in the sake of brevity and efficiency.

There’s plenty of existing content to be recycled and reused or seen and viewed for today including at some of the above links. However, rest assured, there is more content in the works pertaining to enabling Green IT with a focus around data center productivity, efficiency and sustainability, doing more with less, or, doing more with what is available.

So happy earth day 2009, chat with you again soon.

Ok, nuff said.

MSP Business Journal Names Greg Schulz an Eco-tech Warrior

In the April 10th, 2009 issue of the Minneapolis St. Paul (MSP) Business Journal, guess who was named one of three Eco-Tech Warriors? That’s right, yours truly (See the article here).

Photo by Nancy Kuehn – MSP Business Journal

What can I say, I’m flattered and appreciate the coverage. Besides seeing the finished article in the special report, the real fun was doing the photo shoot with the props including the heavy swords, those were not plastic (Hummm, Iron Chef?)!

The photo shoot with the other two “Eco-Warriors” Tom Diamond of New Boundary Technology, and Travis Pakonen of Encompass Solutions along with Nancy Kuehn our photographer as well as the artistic and project management folks from MSP Business Journal were an absolute blast to work with.

For those of you looking for policy management as well as energy management tools for desktops, workstations and PCs, checkout Tom Diamonds New Boundary Technologies and their solutions. Likewise, I hear good things from friends who have used the services of Travis Pakonen and N’Compass for their data center projects.

Ok, nuff said.

Storage Effiency and Optimizaiton – Balancing Time and Space

Storage I/O trends

Here’s a link to the presentation I recently delivered at the Spring 2009 Minneapolis/St. Paul area CMG (Computer Measurement Group – CMG) March 20th, 2009 hosted by Nexus Information Systems and organized by Tom Becchetti. The theme of the event was "Is your storage efficient? There are many ways to rate your storage, how does yours stack up?". Tom organized a great event as usual with a diverse set of speakers for the well attended event graciously hosted by Keith Norbie of Nexus at their Minnetonka facility. The title of my presentation was "Storage Efficiency: Mirror Mirror On The Wall, Who or What is The Most Efficient of Them All? Finding the Correct Balance" that looked at balancing the need to reduce (or maximize) space (utilization) with time (performance) to meet different requirements including maintaining quality of service, response time and availability.

Keeping in mind that there is no such thing as a data or I/O performance recession, there is a common myth that storage optimization or efficiency is all about driving up storage space capacity utilization which can be true for some environments, applications, data or storage types. However there is also the need to maintain or boost performance, reduce response time and latency, doing more work in a more productive and efficieny manner. Not all data or storage can be consolidated to boost utilization without concern for degrading or in any other way penalizing performance, response time or availability.

Thus it is about time and space, that is, balancing data movement and processing rates with storage space capacity utilization and that sometimes, more is not better for performance when it comes to ratios or the number of components in a solution.

Likewise there is the need to balance energy avoidance with energy efficient, balancing the need to store more data in a smaller footprint using less energy and the need to process more data in less time efficiently for productivity.

These and other related themes are expanded on in more detail in my book "The Green and Virtual Data Center" (CRC). These and other related themes will covered in one of my upcoming presentations (The Other Green — Storage Efficiency and Optimization) at StorageDecisions in Chicago the week of June 1st, 2009, as well as in various seminars and events that I will be involved in the coming weeks and months.

Thanks to all those who helped organize, support, sponsored, presented and attended the recent CMG event, look forward to seeing or hearing from you all again soon.

Storage Decisions Spring 2009 Sessions Update

StorageDecisions Logo

The conference lineup and details for the Spring 2009 Storage Decisions event (June 1st and 2nd) in Chicago is coming together including two talks/presentations that I will be doing. One will be in Track 2 (Disaster Recovery) titled "Server Virtualization, Business Continuance and Disaster Recovery" and the other in Track 6 (Management/Executive) titled "The Other Green — Storage Efficiency and Optimization" with both sessions leveraging themes and topics from my new book "The Green and Virtual Data Center" (CRC).

Track 2: Disaster Recovery
Server Virtualization, Business Continuance and Disaster Recovery
Presented by Greg Schulz, Founder and Senior Analyst, StorageIO
Server virtualization has the potential to bring sophisticated business continuance (BC) and disaster recovery (DR) techniques to organizations that previously didn’t have the means to adopt them. Likewise, virtualized as well as cloud environments need to be included in a BC/DR plan to enable application and data availability. Learn tips and tricks on building an accessible BC/DR strategy and plan using server virtualization and the storage products that enable efficient, flexible green and virtual data centers.

Topics include:
* Cross technology domain data protection management
* Tiered data protection to stretch your IT budget dollar
* What’s needed to enable BC/DR for virtualized environments
* How virtualization can enable BC/DR for non-virtualized environments
* General HA, BC/DR and data protection tips for virtual environments

Track 6: Management/Executive
The Other Green — Storage Efficiency and Optimization
Throw out the "green“: buzzword, and you’re still left with the task of saving or maximizing use of space, power, and cooling while stretching available IT dollars to support growth and business sustainability. For some environments the solution may be consolation while others need to maintain quality of service response time, performance and availability necessitating faster, energy efficient technologies to achieve optimization objectives. To accomplish these and other related issues, you can turn to the cloud, virtualization, intelligent power management, data footprint reduction and data management not to mention various types of tiered storage and performance optimization techniques. The session will look at various techniques and strategies to optimize either on-line active or primary as well as near-line or secondary storage environment during tough economic times, as well as to position for future growth, after all, there is no such thing as a data recession!

Topics include:
* Energy efficiency (strategic) vs. energy avoidance (tactical)
* Optimization and the need for speed vs. the need for capacity
* Metrics and measurements for management insight
* Tiered storage and tiered access including SSD, FC, SAS and clouds
* Data footprint reduction (archive, compress, dedupe) and thin provision
* Best practices, financial incentives and what you can do today

See you in Chicago in June if not before then. Learn more about other upcoming events and activities on the StorageIO events page.

Storage Optimization: Performance, Availability, Capacity, Effectiveness

Storage I/O trends

With the IT and storage industry shying away from green hype, green washing and other green noise, there is also a growing realization that the new green is about effectively boosting efficiency to improve productivity and profitability or to sustain business and IT growth during tough economic times.

This past week while doing some presentations (I’ll post a link soon to the downloads) at the 2008 San Francisco installment of Storage Decisions event focused on storage professionals, as well as a keynote talk at the value added reseller (VAR) channel professional focused storage strategies event, a common theme was boosting productivity, improving on efficiency, stretching budgets and enabling existing personal and resources to do more with the same or less.

During these and other presentations, keynotes, sessions and seminars both here in the U.S. as well as in Europe recently, these common themes of booting efficiency as well as the closing of the green gap, that is, the gap between industry and marketing rhetoric around green hype, green noise, green washing and issues that either do not resonate with, or, can not be funded by IT organizations compared with the disconnect of where many IT organizations issues exist which are around power, cooling, floor space or footprint as well as EH&S (Environmental health and safety) and economics.

The green gap (here, and here, and here) is that many IT organizations around the world have not realized due to green hype around carbon footprints and related themes that in fact, boosting energy efficiency for active and on-line applications, data and workloads (e.g. doing more I/O operations per second-IOPS, transactions, files or messages processed per watt of energy) to address power, cooling, floor space are in fact a form of addressing green issues, both economic and environmental.

Likewise for inactive or idle data, there is a bit more of a linkage that green can mean powering things off, however there is also a disconnect in that many perceive that green storage for example is only green if the storage can be powered off which while true for in-active or idle data and applications, is not true for all data and applications types.

As mentioned already, for active workloads, green means doing more with the same or less power, cooling and floor space impact, this means doing more work per unit of energy. In that theme, for active workload, a slow, large capacity disk may in fact not be energy efficient if it impedes productivity and results in more energy to get the same amount of work done. For example, larger capacity SATA disk drives are also positioned as being the most green or energy efficiency which can be true for idle or in-active or non performance (time) sensitive applications where more data is stored in a denser footprint.

However for active workload, lower capacity 15.5K RPM 300GB and 400GB Fibre Channel (FC) and SAS disk drives that deliver more IOPS or bandwidth per watt of energy can get more work done in the same amount of time.

There is also a perception that FC and SAS disk drives use more power than SATA disk drives which in some cases can be true, however current generations of high performance 10K RPM and 15.5K RPM drives have very similar power draw on a raw spindle or device basis. What differs is the amount of capacity per watt for idle or inactive applications, or, the number of IOPS or amount of performance for active configurations.

On the other hand, while not normally perceived as being green compared to tape or IPM and MAID (1st generation and MAID 2.0) solutions, along with SSD (Flash and RAM), not to mention fast SAS and FC disks or tiered storage systems that can do more IOPS or bandwidth per watt of energy are in fact green and energy efficiency for getting work done. Thus, there are two sides to optimizing storage for energy efficiency, optimizing for when doing work e.g. more miles per gallon per amount of work done, and, how little energy used when not doing work.

Thus, a new form of being green to sustain business growth while boosting productivity is Gaining Realistic Economic Efficiency Now that as a by product helps both business bottom lines as well as the environment by doing more with less. These are themes that are addressed in my new book

“The Green and Virtual Data Center” (Auerbach) that will be formerly launched and released for generally availability just after the 1st of the year (hopefully sooner), however you can beat the rush and order your copy now to beat the rush at Amazon and other fine venues around the world.

EPA Draft 3 of Energy Star for Computer Server Specification

Storage I/O trends

Today is the 2008 USA general election today pitting democratic senator Barack Obama vs. republican senator John McCain as well as several other lesser known party candidates who have made comments about the environment and going green as well as the economy, all of which have an impact on IT spending not to mention green IT and green computing.

Today is also the day that the US Environmental Protection Agency (EPA) sent out notification that Draft 3 of Energy Star for computer server specifications are available for comment (See here).

Energy Star is not a new program for IT equipment having been around for some time on PCs and other commodity products as well as many consumer goods. The EPA has been working on several Energy Star programs pertaining to IT data centers in addition to the Server specification working with industry groups covering servers, storage, networking and facilities among others, all of which to help enable the green and virtual data center on a go forward basis.

If you have not done so, check out the EPA Energy Star for data center programs.

The Many Faces of Solid State Devices/Disks (SSD)

Storage I/O trends

Here’s a link to a recent article I wrote for Enterprise Storage Forum titled “Not a Flash in the PAN” providing a synopsis of the many faces, implementations and forms of SSD based technologies that includes several links to other related content.

A popular topic over the past year or so has been SSD with FLASH based storage for laptops, also sometimes referred to as hybrid disk drives along with announcements late last year by companies such as Texas Memory Systems (TMS) of a FLASH based storage system combining DRAM for high speed cache in their RAMSAN-500 and more recently EMC adding support for FLASH based SSD devices in their DMX4 systems as a tier-0 to co-exist with other tier-1 (fast FC) and tier-2 (SATA) drives.

Solid State Disks/Devices (SSD) or memory based storage mediums have been around for decades, they continue to evolve using different types of memory ranging from volatile dynamic random access (DRAM) memory to persistent or non-volatile RAM (NVRAM) and various derivatives of NAND FLASH among other users. Likewise, the capacity cost points, performance, reliability, packaging, interfaces and power consumption all continue to improve.

SSD in general, is a technology that has been miss-understood over the decades particularly when simply compared on a cost per capacity (e.g. dollar per GByte) basis which is an unfair comparison. The more approaches comparison is to look at how much work or amount of activity for example transactions per second, NFS operations per second, IOPS or email messages that can be processed in a given amount of time and then comparing the amount of power and number of devices to achieve a desired level of performance. Granted SSD and in particular DRAM based systems cost more on a GByte or TByte basis than magnetic hard disk drives however it also requires more HDDs and controllers to achieve the same level of performance not to mention requiring more power and cooling than compared to a typical SSD based device.

The many faces of SSD range from low cost consumer grade products based on consumer FLASH products to high performance DRAM based caches and devices for enterprise storage applications. Over the past year or so, SSD have re-emerged for those who are familiar with the technology, and emerged or appeared for those new to the various implementations and technologies leading to another up swinging in the historic up and down cycles of SSD adoption and technology evolution in the industry.

This time around, a few things are different and I believe that SSD in general, that is, the many difference faces of SSD will have staying power and not fade away into the shadows only to re-emerge a few years later as has been the case in the past.

The reason I have this opinion is based on two basic premises which are economics and ecological”. Given the focus on reducing or containing costs, doing more with what you have and environmental or ecological awareness in the race to green the data center and green storage, improving on the economics with more energy efficiency storage, that is, enabling your storage to do more work with less energy as opposed to avoiding energy consumption, has the by product of improved economics (cost savings and improved resource utilization and better service delivery) along with ecological (better use of energy or less use of energy).

Current implementations of SSD based solutions are addressing both the energy efficiency topics to enable better energy efficiency ranging from maximizing battery life to boosting performance while drawing less power. Consequently we are now seeing SSD in general are not only being used for boosting performance, also we are seeing it as one of many different tools to address power, cooling, floor space and environmental or green storage issues.

Here’s a link to a StorageIO industry trends and perspectives white paper at www.storageio.com/xreports.htm.

Here’s the bottom line, there are many faces to SSD. SSD (FLASH or DRAM) based solutions and devices have a place in a tiered storage environment as a Tier-0 or as an alternative in some laptop or other servers where appropriate. SSD compliments other technologies and SSD benefits from being paired with other technologies including high performance storage for tier-1 and near-line or tier-2 storage implementing intelligent power management (IPM).
