will want to invest in a dedicated data center such as RACK59.
How much storage capacity will you need? Will you be able to add additional storage on-demand? How much data availability are you going to need?
Direct Attached Storage (One-to-One): DAS is adding an external storage device to an existing server or PC to extend storage capacity. DAS is suited for newer small businesses with limited storage needs. Examples of this type of storage are portable USBs, thumb drives, zip drives and the PC external hard drive.
Network Attached Storage (One-to-Many): NAS makes stored data and files available to multiple users in multiple locations, using different operating systems. NAS servers utilize file level transfers, while DAS and SAN block level transfers. Example of this type of storage are file servers, email archiving and storing media files for web apps.
Storage Area Networks (Any-to-Any): SAN makes all storage devices available to any server on the network. Most businesses use SAN for over half of their storage needs. SANs are more complex to manage, but the ability to share the storage on multiple servers allows you to configure storage capacity as needed. Examples of this type of storage are entry-level virtualization, supporting interrelated resources, databases and centralizing enterprise storage.
Cloud (Masses-to-Masses): Cloud is pooled server resources that house massive data stores in remote data centers able to scale on-demand. Examples of this type of storage are serving rich media files, content delivery networks and web hosting. The major differences between all four of the storage solutions are cost, whether storage is shared or dedicated and whether additional storage can be added on-demand.
Sometimes it’s hard to conceptualize the vastness of disk storage. It’s easier to look at a bookcase full of rare first editions and understand the amount and value of information. Here’s a break down on the size of different forms of data as defined by the IBM Dictionary:
Bit: A Bit is the smallest unit of data that a computer uses. It can be used to represent two states of information, such as Yes or No.
Byte: A Byte can represent 256 states of information, for example, numbers or a combination of numbers and letters. One Byte could be equal to one character. Ten Bytes could be equal to a word. 100 Bytes would equal an average sentence.
Kilobyte: One Kilobyte would be equal to this paragraph you are reading, whereas 100 Kilobytes would equal an entire page.
Megabyte: Fifteen years ago, a Megabyte was considered a large amount of data. Today a 500 Gigabyte computer hard drive is common. An old 3-1/2 inch floppy disks can hold 1.44 Megabytes or the equivalent of a small book. 100 Megabytes might hold a couple volumes of Encyclopedias. 600 Megabytes is about the amount of data that will fit on a CD-ROM disk.
Gigabyte: One Gigabyte could hold the contents of about 10 yards of books on a shelf. 100 Gigabytes could hold the entire library floor of academic journals.
Terabyte: One Terabyte could hold about 3.6 million 300 Kilobyte images or about 300 hours of good quality video. A Terabyte could hold 1,000 copies of the Encyclopedia Britannica. Ten Terabytes could hold the printed collection of the Library of Congress. That's a lot of data.
Petabyte: One Petabyte could hold approximately 20 million 4-door filing cabinets full of text. It could hold 500 billion pages of standard printed text. It would take about 500 million floppy disks to store the same amount of data.
According to the MGI Big Data Report, the United States Library of Congress is storing around 235 Terabytes of data and 88% of industries have more data than that. Enterprises are in someway liable for nearly 80% of the digital universe. Businesses have steady daily file creation and the amount of information stored within the company will quickly amass. Precious items should be kept in a safe place and your data is no different.

I have always wanted to attend the massive Consumer Electronics Show (CES) that happens ever year in Las Vegas around this time. I imagined it as this sprawling, hypnotic disneyland of amazing technology and spectacle. A place to see the all your dreams of the future laid out around you like a feast. Where else are you going to learn about the new toys and gadgets that you will be drooling over in the stores next year? Companies like Sony and Microsoft spend all year planning how they will get the most attention at shows like CES. They spend huge amounts of money on booth decorations and lighting. They hire actors and stuntmen to make flashy dramatic entrances. They plant beautiful, evocatively dressed young ladies around their products, hoping to attract more eyes than the next company. But as I sat watching Leo Leporte walk through the convention center yesterday, all streaming to me live thanks to the magic of the modern internet, it occurred to me that these huge trade shows may be entering their twilight years. Watching Twit Live allowed me to be there without having to be there, and more importantly, without having to purchase a ticket to attend. I am sure that I missed out on some of the pure amazement and spectacle that you experience by being there in person. I am sure that things like the large beautiful 3D tvs do not seem very impressive when seen through a normal video stream, and standing next to a lovely young women in a tight Sony T-shirt is much more compelling that seeing her on a laptop screen, but otherwise, I felt like I was there. I was finally getting to attend CES, all without having to deal with the hassle of travel, and the crush of thousands of other technology geeks. I was getting to see all of the new toys and gadgets, and thanks to the power of an internet celebrity like Leporte, I was actually getting to see more than I would have as a normal visitor. I was getting to see interviews with, and hands on demonstrations by, the people behind the tech. Wow, why bother going now? But as powerful as that question is, it really doesn't seem as important as it once would have been. Now that sites likeCNet, Engadget, and Gizmodo are covering not only events like CES thoroughly, but also offering a year round spotlight on everything tech and gadget related, companies are starting to realize that they do not need to spend a ton of time and money to have a presence at huge events like CES. As a matter of fact, this will be the final year that Microsoft will be doing the keynote at CES. That fact alone tells you that interest in the trade show is waning. Apple has already pulled out of Macworld in a huge way and instead started doing their own events anytime they want to make an announcement to the world and it is working. Even if companies wanted to wait for events like CES to make their big announcements, frequent leaks and rampant internet speculation often steal the thunder from what they waited to unveil. If news sites are discussing photos and specs in detail weeks before your big unveiling, why bother with it. Controlling the flow of information becomes harder the longer you wait and CES only happens once a year. For this reason, many products are now being announced long before the big events, even if the product is not actually ready. Based on these changes in the mind set of companies and visitors, I expect that these large shows will start to fade into the background and eventually disappear altogether as the expense and effort eclipse the return. So if you want to attend an event like CES in person, you better do it soon. It may not be here in a few years. Or just watch twit.tv, like I do.
Datacenterknowledge.com is rolling out a review of the best writing about cloud computing in 2011.
One of the best columns was writing in October by Michael Jackson , co-founder of Adaptive Computing. Jackson wrote about the increasing importance of cloud computing to business enterprise needs. Below is an excerpt:
Increasingly, cloud computing has become an IT priority for virtually every organization in business today. According to a June 2010 Pew Research Center survey, a decisive majority of technology professionals predict that, by 2020, most people will access software applications online and work through remotely-accessed server networks. SaaS (Software as a Service) cloud applications such as Salesforce.com and NetSuite are standard, acceptable alternatives to traditional client server enterprise applications. A new competitor to Amazon’s EC2 service surfaces almost every day, and virtually every technology company is incorporating the word “cloud” somewhere in their description.
Given these rapid developments in cloud technologies and services, what are some of the key components to watch for as your enterprise moves into this new IT architecture?
Decision Engine
The technological foundation of a cloud computing environment lies within the decision engine. A unique multi-dimensional and predictive decision engine is one that dynamically manages workloads and resources so cloud environments self-optimize to produce more results, with greater speed and efficiency. Having a limited static cloud, with no decision engine adversely impacts the scalability/elasticity of your cloud environment, the largest benefit to deploy solutions in the cloud. If your workload peaks during an off-hour, is your cloud able to anticipate the need to provision more services? Or will it collapse under the weight of higher than anticipated demand?
Having a multi-dimensional decision engine, with the ability to dynamically provision for an unexpected spike in demand, not only affects your cloud’s uptime under Service Level Agreements (SLAs), but also the speed with which your cloud can make crucial decisions.
