First, off I want to say what an awesome year IBM had in storage! We announced several new products and improvements to older ones. SONAS was one of the NAS product of 2010 at IBM. The idea that came from bringing a parallel file system and merging it with commodity parts is brilliant. People have been building these systems for years and having to deal with the issues of interoperability and supportability, can now focus more on making storage work for them. Real Time Compression was also released for the N series product. This was an acquisition that really helps IBM position compression technology in the NAS market. RTC today is an appliance that compresses the data into smaller packages with no performance degrade. I believe we will see more of this technology spread into other aspects of storage line.
The biggest storage announcement was definitely the introduction of a new mid-tier storage device, Storwize V7000. This device is based on the tried and true SVC code base with some new enterprise class features from our DS8000 line. This system has the cool XiV like interface and a very cool form factor and with things like easy-tier and disk virtualzation, the box is going to be hard to beat in 2011.
Second, I want to honor IBM as we celebrate our centennial year of business. The Computing Tabulating Record Company started on June 15, 1911 and while the name has changed and our products and services have changed, but our mission and dedication to our clients remains unchanged. So many of us do not even begin to understand the role IBM has made on our world as it is today. IBM has been well known through most of its recent history as one of the world's largest computer companies and systems integrators. With over 388,000 employees worldwide, IBM is one of the largest and most profitable information technology employers in the world. IBM holds more patents than any other U.S. based technology company and has eight research laboratories worldwide. The company has scientists, engineers, consultants, and sales professionals in over 170 countries. IBM employees have earned Five Nobel Prizes, four Turning Awards, five National Medals of Technology and five National Medals of Science.
Lastly, I want to challenge everyone, IBMers, clients, everyone, to really look at what is going on in the storage space this year. With the explosive growth of data we are seeing people buying unprecedented amounts of storage. Most of the vendors are going to be investing in R & D for storage and coming out with new and time saving features. Clients should challenge their vendors to exceed their requirements not just make them. I also want vendors to look beyond products and start looking the services that help clients make better decisions and support the products they have purchased.
Good luck to everyone in the New Year!
Netapp, for some reason, has removed the SVC from their interoperability list of storage subsystems under a V series. The development team at Netapp has for months not kept up the development and testing for support on SVC (and other storage platforms). This was no more evident when the Storwize V7000 was announced last year that runs the same code base as the SVC system and Netapp refused to offer any support for the product. The lack of support probably comes from the V series team feeling threaten by the virtualization power of the SVC code. These two systems do have some similar capabilities but we find them in different parts of the data center. The V series / Gateway is more of a host to another storage system. It treats the luns presented to it as disk and then presents another protocol out to another host or client. SVC is more a virtualization engine for all the storage and allows customers to move data around in pools that can cross storage subsystems with out the end user knowing.
With all this said, IBM has stepped up and is continuing support for the N series and Netapp models in front of the SVC or the Storwize V7000. As my fellow IBM blogger "The Storage Buddhist" the place for support is not Netapp, but IBM. I stole this chart from his blog to show the levels of code and models supported.
BM N series Gateway and NetApp
For those who have V filers / Gateways today, your support should not change, but if you do run into issues where Netapp is denying you support on this environment, feel free to comment here.
Quick and simple new way to look at storage. Stop buying flash arrays that offer a bunch of bells and whistles. Two main reasons, 1. It increases your $/TB and 2. It locks you into their platform. Lets dive deeper.
1. If you go out and buy an All Flash Array (AFA) from one of the 50 vendors selling them today you will likely see there is a wide spectrum not just from the media (eMLC, MLC, cMLC) but also in the features and functionality. These vendors are all scrambling to put in as many features as possible in order to reach a broader customer base. That said, you the customer will be looking to see which AFA has this or is missing that and it can become an Excel Pivot Table from hell to manage. The vendor will start raising the price per TB on those solutions because now you can have more features to do things therefore you now have more storage available or data protection is better. But the reality is you are paying the bills for those developers who are coding the new shiny feature in some basement. That added cost is passed down to the customer and does increase your purchase price.
2. The more features you use on a particular AFA, the harder it is to move to another platform if you want a different system. This is what we call 'stickiness'. Vendors want you to use their features more and more so that when they raise prices or want you to upgrade it is harder for you to look elsewhere. If you have an outage or something happens where your boss comes in and say "I want these <insert vendor name> out of here", are you going to say well the whole company runs on that and its going to take about 12-18 months to do that?
I bet your thinking well I need those functions because I have to protect my data or i get more storage out of them because I use this function, but what you can do is take those functions away from the media and bring it up into a layer above them in a virtual storage layer. This way you can move dumb storage hardware in and out as needed and more based on price and performance than feature and functionality. By moving the higher functionality into the virtual layer the AFA can be swapped out easily and allow you to always look at the lowest price system based solely on performance.
Now your thinking about the cost of licenses for this function and that feature in the virtualization layer and how that is just moving the numbers around right? wrong! For IBM Spectrum Virtualize you buy a license for so many TBs and that license is perpetual. You can move storage in and out of the virtualization layer and you do not have to increase the amount of licenses. For example. You purchase 100TB of licenses and your virtualize a 75TB Pure system. You boss comes in and says, I need another 15TB for this new project that is coming online next week. You can go out to your vendors and choose a dumb storage AFA array and insert it into the virtual storage layer and you still get all of the features and functions you had before. Then a few years go by and you want to replace the Pure system with a nice IBM flash system. No problem, with ZERO downtime you can insert the Flash 900 under the virtual layer, migrate the data to the new flash and the hosts do not have to be touched.
The cool thing that I see with this kind of virtualization layer is the simplicity of not having to know how to program APIs, or have a bunch of consultants come in for some long drawn out study and then tell you to go to 'cloud'. In one way this technology is creating a private cloud of storage for your data center. But the point here is by not having to buy licenses for features every time you buy a box allows you to lower that $/TB and it gives you the true freedom to shop the vendors.
