Cloud Optimized Storage: Atmos

In 1969 during the original Star Trek TV show, The Cloud Minders episode featured Stratos, a city in the clouds. Today, EMC launches Atmos, cloud optimized storage. This is not science fiction, but the realization of much work on managing very large amounts of data “in the cloud.” Having been in the hands of customers since early Summer, this offering is intended to manage massive amounts of Internet-based information. How massive? Petabytes to begin with.

Forecast: Cloudy?

“Cloud computing” is a very popular topic right now, and there is often more heat than light shed on the subject. EMC releases Atmos at a time when many others are still debating over cloud computing and arguing whether it is or is not grid computing, software as a service, outsourcing, or Web 2.0-based data.

The Atmos sphere

What does Atmos encompass? First, it is different than simply block-based Storage Area Networks (SAN), file-based Network Accessed Storage (NAS), or even object-based Content Addressed Storage (CAS). EMC introduced CAS in the Spring of 2002 with the launch of Centera, part of an object-based archiving and compliance solution. As revolutionary as this was half a decade ago, so too is COS today.

  • Massive Scalability

Global manageability through a namespace, regardless of geographical location. Multi-tenancy means that different tenants could store their unique information objects in their own private namespace under the Atmos namespace.

  • Policy Based Information Management

Information can be managed by policy, and automatically acted upon by business rules for the metadata that defines the policy. For example, if an object conforms to a policy of “popular”, it could be replicated appropriately to deliver better service levels to users. When demand drops off and it becomes less “popular” the number of copies could be automatically pruned.

  • Operational Efficiency

Whether it’s a drive, server, or network — all of this can be seen and managed from a single console.

 

There are many excellent articles available already that explain this in greater detail. Check out Chuck Hollis at Chuck’s Blog, Mark Twomey at Storagezilla, Steve Todd at Information Playground, Dave Spencer at Dave Talks Shop, Dave Graham at Dave Graham’s Weblog, and Len Devanna’s summary.

Information Growing Exponentially

Exponential GrowthWhy Info Exponential? Because information is growing faster right now than it ever has in history.

Much of it is coming from so called “end users” like you and me. IDC estimates 70% will come from individual creation by 2010. Personally, I create a data wake, or digital footprint of about 10 gigabytes a day — including all my emails, digital photos, TV DVR recordings, cell phone usage, Internet use and “click stream”, even pictures of me by airport surveillance cameras. That can add up. How fast? This counter below shows how much information I’ve created directly or indirectly since the beginning of the year:

But this is just me. Consider the wider population and their contribution to the "digital shadow." What if you add all of them up? IDC calculated that in 2007 the digital shadow was about 281 exabytes or 281 billion gigabytes. This counter shows the current results:

Would you like to calculate your digital shadow? Check out the personal digital footprint calculator at EMC's website here.

But this growth is not just incremental, it's accelerating. There is a group of people who Gartner Research calls "Generation Virtual." Unlike previous generations, who are usually defined by age, Generation V, regardless of:

gender, social demographic or geography ... demonstrated achievement, accomplishments and an increasing preference for the use of digital media channels to discover information, build knowledge and share insights.

This generation is growing, and changing. My own use, consumption, and generation of information has changed, even over the last few years.

2003I recall a research project conducted at the University of California, Berkeley and sponsored by EMC Corporation -- just five years ago -- that concluded the following:

  • The amount of new information stored on paper, film, optical and magnetic media reached about five exabytes - or 5 million terabytes - in 2002, compared to about half that in 1999.
  • Some 92 percent of new information is stored on magnetic media, primarily hard drives.
  • New information flowing electronically on radio, television and the Internet in 2002 totaled nearly 18 exabytes.
  • The phone accounts for the largest percentage of information flow, with e-mail placing second.
  • While original information on paper continues to grow, most comes in the form of office documents and mail - not books, newspapers and journals.
  • Worldwide production of books increased by 2 percent in the last year.
  • Production of newspapers in the last year decreased by 2 percent.
  • The United States produces 35 percent of all print material, 40 percent of the images and more than half of the digitally stored material.
  • Peer-to-peer file sharing has exploded, and MP3 music files and digital video accounted for 70 percent of the files on the hard disks of users who participate in online file exchanges.
  • Globally, the average Internet user spends 11.5 hours online per month, but the average Internet user in the United States spends more than twice that amount.

Remember, this information is 5 years old!

This blog intends to cover subjects that address the phenomenon of exponentially explosive information growth, and EMC's leadership role in addressing it.

Welcome aboard, and fasten your seat belt low and tight across your lap.

B2D and TiVo

image While giving a talk to a group of sales reps in New York, we were discussing the concepts of Backup to Disk (B2D) and Virtual Tape Libraries (EMC Disk Library). Some of these folks were quite experienced as sales reps, but didn’t quite understand the value proposition of the Disk Library.

At one point, the conversation got around to the Yankees, as I imagine often happens in NYC, and the Sales Manager said,

“Yeah, I’m going to TiVoTM the game tonight so I don’t miss it while I am taking the train home.”

I asked the group, knowingly,

“How many of you use TiVo or other Digital Video Recorders?”

Most of the hands went up.

“Would you ever go back to using VCR tape recording?”

Universal “No’s” came back.

I continued,

“That’s what backing up to disk is all about. You get the benefits of speed, faster seeking, instant playback, etc…”

You could see the lights going on in their eyes.

I love it when that happens.
