For those of us old-timers who muscled 9-track tapes on 10 ft tall on Burroughs B-3500 mainframe computers tape drives, with a total storage capacity of about 5 kilobytes, the idea of sticking a 64 gigabyte SD memory chip into my laptop computer is pretty cosmic.
Terms like PCAM (punch card adding machines) are no longer part of the taxonomy of information technology, nor would any young person in the industry comprehend the idea of a disk platter or disk pack.
Skipping a bit ahead, we find a time when you could purchase an IBM “XT” computer with an integrated 10 megabyte hard drive. No more reliance on 5.25″ or later 3.5″ floppy disks. Hard drives evolved to the point “Fryes” will pitch you a USB or home network 1 terabyte drive for about $100.
Enter the SSD
October 2009 brings us to the point hard drives are now becoming a compromise solution. The SSD (Solid State Disk) has jumped on the data center stage. With MySpace’s announcement they are replacing all 1770 of their existing disk drive-based server systems with higher capacity SSDs, and quoted that SSDs use only 1% of the power required by disk drives, data center rules are set to change again.
SSDs are efficient. If you read press releases and marketing material supporting SSD sales you will hear numbers like:
- “…single-server performance levels with 1.5GB/sec. throughput and almost 200,000 IOPS
- … a 320GB ioDrive can fill a 10Gbit/sec. Ethernet pipe
- … four ioDrive Duos in a single server can scale linearly, which provides up to 6GB/sec. of read bandwidth and more than 500,000 read IOPS (Fusion.io)
This means not only are you saving power per server, you are also able to pack a multiple of existing storage capacity into the same space as currently possible with traditional disk systems. As clusters of SSDs become possible through additional tech development of parallel systems, we need to mentally get our heads around the concept of a three dimensional storage system, rather than a linear systems used today.
The concept of RAID and tape backup systems may also become obsolete, as SSDs hold their images when primary power is removed.
Now companies like MySpace will be in a really great position to re-negotiate their data center and colocation deals, as their actual energy and space requirements will potentially be a fraction of existing installations. Even considering their growth potential, the reduction in actual power and space will no doubt give them more leverage to use in the data center agreements.
Why? Data center operators are now planning their unit costs and revenues based on power sales and consumption. If a company like MySpace is able to reduce their power draw by 30% or more, this represents a potentially huge opportunity cost to the data center in space and power sales. Advantage goes to the tenant.
The Economics of SSDs
Today, the cost of SSDs is slightly higher than traditional disk systems. Even with fiber channel or Infiniband supporting large disk (SAN or NAS) installations. According to Yahoo Tech the cost of an SSD is about 4 times that of a traditional disk. However they also indicate that cost is quickly dropping, and we will probably see near parity within the next 3~4 years.
Now, if we remember the claim MySpace made that with the SSD migration they will consume only 1% of the power used by traditional disk (that is only the disk, not the entire chassis or server enclosure). If you look through a great white paper (actually it is called a “Green Paper”) provided by Fusion.io you will see that implementation of their SSD systems in a large disk farm of 250 servers (components include main memory, 4xnet cache, 4x tier 1/2/3 storage, tape storage) you will see a reduction from 146.6kw to 32kw for the site.
Data centers can charge anywhere from $120~$225/kw, showing that we could potentially, if you believe the marketing material, see a savings of $20,000/month @ $180/kw. This would also represent 47 tons of carbon, using the Carbon Footprint Calculator.
Fusion .io reminds us that
“In 2006, U.S. data centers consumed an estimated 61 billion kilowatt-hours (kWh) of energy, which accounted for about 1.5% of the total electricity consumed in the U.S. that year, up from 1.2% in 2005. The total cost of that energy consumption was $4.5 billion, which is more than the electricity consumed by all color televisions in the country and is equivalent to the electricity consumption of about 5.8 million average U.S. households.
• Data centers’ cooling infrastructure accounts for about half of that electricity consumption.
• If current trends continue, by 2011, data centers will consume 100 billion kWh of energy, at a total annual cost of $7.4 billion and would necessitate the construction of 10 additional power plants. (from “Taming the Power Hungry Data Center”)”
When we consider the potential impact of data center consolidation through use of virtualization and cloud computing, and the rapid advancements of SSD technologies and capacities, we may be able to make a huge positive impact by reducing the load Internet, entertainment, content delivery, and enterprise systems will have on our use of electricity – and subsequent impact on the environment.
Of course we need to keep our eyes on the byproducts of technology (e-Waste), and ensure making improvements in one area does not create a nightmare in another part of our environment.
Some Additional Resources
StorageSearch.Com has a great listing of current announcements and articles both following and describing the language of the SSD technology and industry. There is still a fair amount of discussion on the quality and future direction of SSDs, however the future does look very exciting and positive.
For those of us who can still read the Hollerith coding on punch cards, the idea of >1.25TB on and SSD is abstract. But abstract in a fun, exciting way.
How do you feel about the demise of disk? Too soon to consider? Ready to install?

Rob Bernard knows green. As the Chief Environmental Strategist at Microsoft he walks the talk of reducing our carbon footprint, and evangelizing the impact of our actions on both the environment and quality of life. Our quality of life, and the quality of life others on the planet wish to enjoy.
Our Commitment
At Microsoft we are committed to software and technology innovations that help people and organizations around the world improve the environment. Our goal is to reduce the impact of our operations and products, and to be a leader in environmental responsibility.
(From Rob Bernard’s presentation at Data Center Dynamics, 6 Aug 09, Bellevue, WA)
Rob told the story of his first week at Microsoft. In their Redmond campus, Microsoft provided logo Styrofoam coffee cups to both visitors and employees. Lots of cups. Almost two million Styrofoam cups a year ended up in the trash.
Immediately prior to joining Microsoft, Rob had taken his family on a short trip to Oregon, where he stopped for a coffee break, and noticed the barrister provided him a paper coffee cup that included a printed notice the cup would bio-degrade within 30 days of use. Dust to dust. And about the same price as the Styrofoam cups. Those environmentally unfriendly landfilling non-biodegradable Styrofoam coffee cups.
Needless to say, Microsoft is now using biodegradable coffee cups, made from recycled paper stock.
The Green Telephone
Rob gave another example of simple things we can do. Oddly, he was not evangelizing Microsoft products, but rather talking to us as one planet resident to another planet resident. He gave the example of telephones, computers, and video. Most of us have a telephone plugged into the wall at home, next to a desktop or personal computer, in the same room as a television set.
Rob simply explained that he has now unplugged the telephone and television, and uses all three services off a lower power draw “Energy Star” computer. No more need to burn electricity to power redundant utilities within the house.
Microsoft Carbon Production
Microsoft is not perfect. In fact Rob noted as a company they had produced more than 936,000 tons of carbon in 2008. This is considered a grossly unsatisfactory condition for a company such as Microsoft, which employs some of the greatest minds in the world. Now Microsoft is on a corporate search and destroy mission to seek out and eliminate waste. Not only internally, but also to provide the lessons learned in the quest to reduce their negative impact on the planet to everybody. Kind of “open source” green.
Part of the philosophy is to lead by example, within the Microsoft campus, and stress to employees that everything learned at campus may be transferrable to their personal lives and homes.
Act with Transparency, Let Employees Inspire
- Understand your impact
- Share and borrow best practice
- Employees lead by example
- Compostable dishware
- Connector Bus (employee transportation from home or “park and rides”)
- Kitchen Grease (contribute to bio-deisel)
- Help individuals drive change
- Support employee engagement
- Measure, measure, measure
(From Rob Bernard’s presentation at Data Center Dynamics, 6 Aug 09, Bellevue, WA)
He actually believes, evangelizes, and strongly urges Microsoft employees to live the talk.
The Data Center Challenge
Rob advised the delegates the US Government is preparing to study the potential of taxing data center operators who consume too much utility power. He went on to urge data center operators to aggressively attack the existing inefficiencies of data center designs, and start a structured approach to rethink, rebuild, and redesign our approach to data centers.
Do you use blanking panels to reduce inter-cabinet hot air recirculation? Are you working on consolidating individual applications into server-based applications? Do you really understand the implications of running high powered computer and server systems which only use 5~10% of their CPU and disk capacity? When possible, do you insist on buying and deploying “Energy Star” equipment, for, well,… for everything?
One problem many data center operators have is they really don’t even know how much energy their data center, much less individual components of the data center, is actually using. As much as we’ve seen it in the news, most data center operators have not even attempted to calculate their Power Utilization Efficiency (PUE) rating or factor. That is the equation that shows how much power you consume for support services in the data center vs. actual power being applied to IT equipment and operations.
Bottom line is how do we fix problems when we have not even audited our equipment and power consumption? We’ve got to get smart. A data center drawing 10 megawatts of power is producing a creepy amount of carbon, so we better start taking it seriously. And oh yeah, the government is going to eventually regulate our industry (since some data centers consume nearly as much energy as the city of Fresno), and penalize those data center operators who cannot prove their efficient use of power.
Consider the Cloud
It is here. It is working. It helps consolidate inefficient data centers into efficient data centers, eliminating much of the unused processing and storage capacity we insist on burning our limited CAPEX to fund. If we can bring our cloud utilization up to 80% through virtualization of existing stand alone server systems, well – we will recover considerable operational and capital expenses by eliminating hardware that consumes electricity, space, and costs a lot to purchase.
Smaller companies can gain even larger benefit by outsourcing their processing and storage to commercial cloud Infrastructure and Software as a service (IaaS/SaaS) providers, eliminating their need to operate a data center – period.
Rob Sells the Audience
Throughout his presentation the audience remained silent, fixed on his words. It is easy to listen to a man who not only knows his material cold, but also projects an enthusiasm which reaches into the soul of everybody present. And those who were squeezing into the back of the room to hear more of his ideas, stories, and visions of a greener future.
I am sold, as were a couple hundred other conference participants. I want to be green, and will not only try to bring more conscientious effort to my personal life, but also become a micro-evangelist in my company. And a macro-evangelist to my industry.

John Savageau, Long Beach
In 1938 Hawaii’s surfing legend Duke Kahanamoku held the first US national surf contest on the shores of San Pedro Bay in Long Beach, California.
For a variety of reasons, including development of Long Beach as a deep water port and use of Long Beach by the US Navy, a nine mile 50 foot deep breakwater extending nearly 12 feet above the ocean was built between 1932 and 1949. The breakwater is owned by the US government, and thus the city of Long Beach has been merely an observer in the process over the past 60 years, and has suffered the negative impact of a breakwater which has significantly altered the eco-system of San Pedro Bay.
Google Maps View of Long Beach Breakwater
Impacts of the Long Beach Breakwater
The ocean has a natural flow, developed over millions of years. Currents keep runoff from the land, and other sources such as the Los Angeles River from stagnating in the bay, recycling the water through nature’s own system of environmental maintenance.
Since the natural current of water coming into San Pedro Bay was changed, the current has moved further south along the beach area near the Long Beach Peninsula, resulting in accelerated beach erosion. Property owners are in danger of flooding due to this erosion, and are now being forced to pay for a beach replenishment project needed to protect property when heavy southern swells push massive amounts of water through the narrow inlet created by the breakwater.
While Long Beach has one of the most impressive beaches in the Southern California area, on any given summer day the beaches are nearly deserted. The water, lacking any real recirculation or current, is stagnant and much higher in pollutants than other beaches around the area. The “Save the Bay” organization has a monthly review of all beach areas around Los Angeles County, and routinely fails Long Beach’s coastal areas.
Just a few minutes away, the beaches at Seal Beach, Huntington Beach, or even the South Bay area around Redondo Beach are close enough to provide a much better alternative than spending an afternoon in an unhealthy, sometimes smelly beach such as most of Long Beach.
Legitimate Concerns
Of course, as with all things, this is not a simple issue. The THUMS oil islands would need to be reinforced to withstand additional surf. The areas around Shoreline Village would need some reinforcement, although the breakwaters on the Long Beach Harbor side of the bay would probably not be affected, and Shoreline would be secure.
Since the Naples area was heavily built and populated after construction of the breakwaters, there would also be a potential of higher water levels and flooding within this rather opulent section of town. There is also some disagreement on the potential effect on the Long Beach Peninsula, with some believing removing the breakwater would increase the risk of flooding in that area as well.
Breakwater Politics
On July 24, 2007, the Long Beach City Council directed staff to fund a Long Beach Breakwater Reconnaissance Study. “This reconnaissance study is the first step in answering the community’s questions about the impact and role of the Long Beach Breakwater, and could help determine the future of the City’s coastal areas.” LB Gov
Other organizations, with the “Surfrider Foundation” at the top of the list, have done extensive studies on the oceanic, climate, environmental, and social impacts of the Long Beach breakwater. The Surfrider Foundation has been successful in bringing public attention and awareness to the debate. Their studies are available as detailed reports at:
- Surfrider Foundation Long Beach Breakwater Study
- Kalon Morris report on LB Breakwater
As an emotionally charged issue, politicians are naturally attracted or forced into the discussion. The congressional district of Long Beach falls into the 42nd congressional district, a seat held by Dana Rohrabacher. Rohrabacher has fallen on both sides of the issue, recently bending to the volume of discussion favoring removal of the breakwater.
Long Beach Councilwoman Rae Gabelich is in favor of doing a detailed study of the issue, not making a definitive statement one way or the other.
Frank Colonna, a former council member and resident of the city’s peninsula area was also the lone vote against approving a study two years ago.
On Friday, 26 June (2009) Congresswoman Laura Richardson announced she had secured $100,000 in federal funding to evaluate the Federal interest in a reconfiguration of the Long Beach Breakwater.
“After requesting funding last year, conducting several meetings with the Army Corps and intense negotiations with Appropriations Committee leadership, today all of Long Beach once and for all can review the facts of the longest urban breakwater in the country,” Congresswoman Richardson announced. “This $100,000 allocation for the Army Corps’s reconnaissance report is one of the most vital allocations this region will receive and it is particularly vital in these economic times to ensure an objective evaluation is made so that all resident, business and government issues and concerns are considered.”
Next Steps
The federal announced by Congresswoman Richardson is only the first step in a fairly lengthy process. This first step only funds the Army Corps of Engineers to initiate the “Reconnaissance Study,” which will determine if there is US Government interest in removing or altering the breakwater. If the Army Corps of Engineers determines breakwater alterations are in the government’s interest, they will then create a Project Management Plan (PMP).
The PMP documents the purpose of a feasibility study for the alteration, and tasks needed to complete the project. The PMP may include the City of Long Beach, and recommend a potential agreement that would outline the relationship between the city, the Army Corps or Engineers, and the federal government to complete the project.
This would include items such as who pays what percentage, which agency completes the tasks, and the overall plan to complete the project. This could take years.
On the other hand, we have to start at some point, and Congresswoman Richardson has taken the lead in representing the people of Long Beach in addressing the issue.
What We Can Do
Regardless of which side of the Long Beach Breakwater issue we stand, we need to take a stand. The result of this study and debate will potentially cost the city and government a lot of money, change the environment, and change the value of property near the waterfront. There will be an impact on surrounding communities, and an impact on the oil industry.
On the other hand, maybe someday in the future surfers will return to Long Beach and the city will regain its historical nickname as the “Waikiki Beach of California.”
