Citing a recent survey by Digital Realty Trust, the article reads: “… 70 percent of companies planning data center expansions say they envision large projects of at least 15,000 square feet in size or 2 megwatts or more of power.”

Of all the companies surveyed, a whopping 83 percent said they plan to expand their data centers in the coming 12-24 months. Yet, the availability of this space is dropping precipitously. This could lead to a serious supply and demand crunch, according to Data Center Knowledge. Not only that, but the cost of powering these data centers is already the number one concern for many companies.

What do you think? Is this a concern for your company or those with whom you partner or serve?

However, a company’s core transactional database is the most conservative asset in the data center. Introducing compression would save space, for sure, but you could only use very fast, simple compressors there. At the same time, customers will be hesitant to deploy a new layer of processing in their most sensitive application.

So, where is most data growth? In fact, it’s being driven by unstructured data – Office documents, rich media, email with attachments, PDFs, Flash videos, and so forth. This complex data does not lend itself to fast simple compressors. But perhaps we should back up for a moment and think about how customers have been behaving all along.

Throughout the history of storage, there have always been tradeoffs available between fast expensive storage, and slower but cheaper alternatives. This is not a bad thing. It gives users alternatives based on their priorities and budgets. Back in the old mainframe days, these choices were between very expensive mainframe memory and “offline” storage like drums, cards, and tapes. Today the technology is all much bigger, faster, cheaper and sexier. But really, the tradeoffs are the same.

Data reduction technology adds another layer of choice above and beyond the traditional hardware choices. Now in addition to choosing whether you want fast, expensive solid state disk (SSD) or slower but very cost-effective SATA, you can also choose whether you want to compress and/or deduplicate the data that is stored on those disks.

Just like physical disks, compression and dedupe come in a range of speeds and capabilities. There are simple and very fast compressors that are essentially invisible in terms of their impact on storage performance. There are more complex compressors that get better results, but which may take longer, either to compress or to decompress the data. Deduplication, done well, should always be pretty fast, and streaming dedupe rates of well of 300MB/sec are now available from many vendors (including Data Domain and Ocarina).

The emergence of tools to automatically tier data to its appropriate place help make the use of all of these technologies more feasible. That applies as much to solid state disks as it does to dedupe and compression. When data tiering can be made invisible to end-users and applications, then implementing multiple physical and logical tiers of storage becomes practical.  Good examples would include EMC’s new FAST tools, Compellent’s “Fluid Data Storage”, and HDS’s Data Migrator. When users or administrators have to move data by hand to get it to a compressed tier or a solid state disk, then the operational costs offset the capital savings.

You might want to be wary when someone’s biggest claim to fame is fast dedupe. Just as the old mainframe admin had to decide whether something was important enough to live in RAM, or could be stored on cheaper tapes instead, today’s IT shops have to decide where it is most important to try to get data reduction, and what tool will get the most bang for the buck for that kind of data. You need the whole story, and then you can decide based on your own priorities.

This Saturday I’m participating in an event that aims to bridge the gender gap in computer science and engineering. It’s the first annual Dare2BDigital, a conference for young women in the 7th-10th grades that exposes them to the new and exciting career options that now exist in computer science and engineering.

Why such a young group? Studies suggest this is the time when we begin the decision-making process about our career path. These young women are beginning to make pictures in their minds about how they’ll be spending their days when they enter the workforce. They might well be gifted in math or logic. But computer science still suffers from an image problem. Most people–girls in particular–see it as the realm of geeky guys who make endless Star Trek references, drink too much soda and have questionable grooming habits.

What many don’t know is how far this field has come in the last decade. If you’re creatively inclined, now is one of the best times to enter the vast computing field and start poking around for an interest area. An example, one of the first workshops at Dare2BDigital to fill up was one taught by Pixar technical directors on “Computers, Art, and Animation — How opposing specialties come together to create feature films.” What a a treat for a middle- or high school-aged girl to be able to dip her toes into the exciting field of computer animation. Other popular choices were programming with Python, making a Facebook game (with folks from Zynga), my workshop on being a tech reporter, and others. For the full list of workshops to share with your daughter, go to the workshops page.

The event is sponsored by SAP, along with many other top names in technology, including, HP, Microsoft, Cisco, IBM, Symantec, and others. What do you think? Is this the way to bring more women into the fold? What else can be done to open up the world of computing to more potentially qualified and creative people?

Full disclosure: I personally am receiving a small stipend from the event presenters for my consulting work on this conference. This blog’s parent Ocarina Networks is in no way involved, other than to be supportive of the concept.

One of the persistent myths about the Internet is that it is clean and green. We overestimate the value of going “paperless” while lowballing the effect on the environment of data centers. One need only look at an online pub like Data Center Knowledge to see that one of the most talked about issues in data centers today is how to reduce rack space, cooling and other energy costs associated with storage. (Another great resource is Greg Schulz’s StorageI/O blog.) This is particularly true of the data being generated through our new Web 2.0 sharing habits. Jon Toigo can laugh about the exploding digital universe all he likes, but it’s still the case that data growth is going like gangbusters in this socially networked era. Recession or no recession, there is a growing demand for ways to make storage more efficient.

Large players in this space are all too aware of the environmental and financial costs of such rapid data growth. Every time you share a photo or video, you’re contributing to it. And who among us doesn’t do this nowadays? In response. companies are experimenting with all kinds of techniques, including new building designs making use of outside air, reducing overall rack space usage with data reduction such as is offered by this blog’s parent Ocarina, cloud adoption, and so on and so forth. Companies like Google, Yahoo and Facebook are also creating next generation storage architectures that are more efficient for handling the realities of today’s internet. In short, let’s be sure, as we discuss the fallout from the latest global warming debate that we don’t start acting too lax about the effect of our actions on the planet.

Some of the more thought provoking posts of late:

DCIG - How SSDs can be leveraged to Deliver Inline Deduplication for Primary Storage
Jerome Wendt responds to a comment from someone about Hifn’s Bitwackr inline dedupe. I don’t necessarily agree with Jerome’s take on this. In general, inline solutions are extremely limited, as the original commenter pointed out. But the post provides interesting food for thought.

Storagebod - Where is OnTap 8 with a bit of a rant!
Martin Glassborow isn’t talking specifically about NetApp dedupe here, but the delay on shipping OnTap8 is of interest to anyone who is concerned about data reduction products. As he puts it, the elephant in the room is that A-SIS dedupe as it now stands has limited scalability.

Recovery Monkey - More FUD busting: Deduplication - is variable-block better than fixed-block, and should you care?
This post, by Dmitris Krekoukias, argues that major distinction some vendors make about variable and fixed block deduplication is a way of distracting customers from the real issues. The post served to defend NetApp against its detractors and competitors who say fixed block dedupe is limiting. The comments field is in some ways the most interesting part, with EMC heavy Chuck Hollis raising questions about his connections with NetApp. Also, our own Mike Davis weighed in, and the numbers he cited were so notable that further commenters questioned how this could be lossless compression. At this point, we’re used to it–the industry at large has become accustomed to less than spectacular results. More on all of this in a later post.

And here’s another interesting trend. The word “dedupe” is starting to creep into the lingo in a more general way. Among storage tweeps there is a greater tendency to throw “dedupe” into their conversations about everything from their record collections to what they eat. It reminds me a little bit of the “hepcat” slang I used to hear when hanging around jazz musicians. If something was ordinary, they’d call it “B Flat,” since that’s the most common key in jazz. For example, “Oh, I just had a B Flat lunch today of a burger and fries.”

The often Twit-witty Greg Schulz recently tweeted: “ I can have dvr record on disk NBC tape delay (thats probably on disk) then dedupe da commercials.” Good plan, Greg.

This post by Steve Gillmor at TechCrunch also uses the term–in a way that I’ve never heard anyway. In this case, he’s referring to the fact that there is duplication of content across what are now becoming overlapping social networks–FriendFeed, Twitter, and the new Google Buzz.

OK that’s all for now. Keep on deduping friends!

As regular readers of this blog know, we’re obsessed with out there tech.

The news is sad. The company that was developing it, InPhase, is out of business. Their web site is still up, but according to the article, the company, a Bell Labs spin-off, was shuttered in early February and the Colorado Dept. of Revenue is now seizing its assets. As he points out, for now, technologies like deduplication make it hard to justify spending $10K on holographic drive.

Despite this terrible setback I for one don’t want to believe this idea will die out entirely. It promises a new generation in storage at a time when data growth is spiraling out of control, threatening to overtake data centers worldwide. And who says we can’t add compression and deduplication on top of that? Howard and I both predict that sooner or later someone else will follow the holographic storage clarion call. As he so succinctly put it: “It’s just so cool.”

Here is a video demonstration of the thing. Too bad the Microsoft Surface retails at $12,500+ and is only currently for “commercial” usage such as retail venues.

Here are some of the stops we at Online Storage Op make on a regular basis in order to stay up-date on IT infrastructure news without driving ourselves nuts in the process. We’d love to hear your suggestions–how do you find out what you need to know? What used to work and isn’t so much anymore? What do you wish were out there that isn’t? For now, here’s our list:

TechTarget - Still a prime source of storage news and views, particularly SearchStorage. Reporters to watch: Beth Pariseau and storage gossip watcher Simon Sharwood.

The UK Register - Chris Mellor, Timothy P. Morgan and others continue to churn out solid daily coverage of industry trends, with headlines that might make you laugh out loud.

Gestalt IT - I admit it, there are days when I don’t bother reading anything else except Gestalt to get my daily dose of storage news and views. With a solid lineup of independent writers and objective analysis on industry trends–not to mention the new addition of a humor column–it’s a one stop shop.

Network Computing - For those who used to read Byte & Switch, this is the new site that integrates it with other networking news. A necessary update in these lean times one supposes. Solid regular contributions from such writers as Howard Marks and George Crump offer simple, straightforward information and advice about products and platforms.

Wikibon -Dave Vellante and others contribute to this blog, which picks out some of the hottest trends in storage. A good way to get a quick hit on what the Wikibon analyst community is talking about.

Emulex’s Shared Items - An easy cheat sheet on what the latest industry observers and vendor bloggers are talking about. Easy to track on Twitter or through Google Reader.

Storage Monkeys - This community site has a lot going on, so I tend to just quickly check the blogs and then take a listen to the latest episode of the Infosmack podcast, which is posted each Monday morning. The blogs tend to be a little on the insiderey side, so if you’re not actively working in the data center you might find them too granular. On the other hand, the podcast is very much the 30,000-foot view of overall storage, networking and virtualization trends, served up in a highly entertaining radio format with two great hosts, Greg Knieriemen and Marc Farley.

Twitter - It sometimes seems like more trouble than it’s worth, but truth be told, the best way to find out what people in storage are talking about, worried about, and trying to fix is to sit around and listen to what they’re saying on a daily basis. Go ahead and follow a couple of Storage lists and you’re pretty much all set–here are a few I’d recommend:
