When I first started working at IBM, we had a couple of NAS storage devices: NAS 100, NAS 300(G) and the NAS 500. The NAS 100 was a 1U server appliance that used Windows 2000 and so did the NAS 200 device, all built on IBM hardware. The NAS 500 was on an AIX system also from the IBM stock. They were traditional NAS type systems and IBM sold them as let us build the system for you so you don't have to. Somewhat limited in functionality but did the job they were designed to do, serve NAS data.
That same year, IBM decided to partner with a company that was doing some things in the storage market that looked really interesting. Network Appliance had just started gaining steam with their Data Ontap code (6.something if I remember correctly) and had broken the barrier that IBM systems lacked. Unified protocols from a single architecture and integration into other products like Exchange and SQL using their cool snapshot technology. It took some time to get up to speed on the new Netapp technology with snap this and snap that, but soon we were all talking about waffles and aggrs.
Through out the years, the product set grew and so did the hardware offering. We kept up with the releases and for the most part a 20-60 day lag in release of new software was ok for most IBM customers. We partnered with the sales teams and support teams to help grow the N series customers base and to keep them happy. As with any partnership there are bumps along the way and there seemed to be two parents telling each other they agree to disagree. All in all the N series system has been very successful at IBM.
But as the years progressed, new technology like XiV, Real Time Compression, TSM Flash Copy Manager etc, have filled some of those voids previously filled by N series in the IBM portfolio. As with many companies there are products that overlap and N series does overlap over half of the product line at IBM Storage. Positioning became harder as sales teams questioned when to sale N series and when to sell something "blue". We quickly learned that customers really liked what N series brought to the table and how the solution could be so flexible.
Now with the news of Netapp purchasing Engenio I wonder how the relationship between IBM and Netapp will survive. IBM also rebrands the Engenio products as the IBM DS 3k, 4k and 5k. I guess the bigger question is now what will Netapp do with that product line? If history is any indicator, they will simple keep things like they are for some time and slowly move the customers over to a Data OnTap product. The other question is how long will IBM keep sending money over to Netapp for products that we sale and support?

Every year IBM puts on a conference for all of our clients, business partners and strategic partners.
Now available is the IBM System Storage N series with VMware vSphere
Redbooks are a great way of learning a new technology or a reference for configuration. I have used them for years not just in storage but for X series servers and for software like TSM. The people that write the books spend a great deal of time putting them together and I believe most of them are written by volunteers.
This is the third edition of this Redbook and if you have read this before here are some of the changes:
-Latest N series model and feature information.
-Updated the IBM Redbook to reflect VMware vSphere 4.1 environments
-Information for Virtual Storage Console 2.x has been added
This book on N series and VMware goes through the introduction of both the N series systems and VMware vSphere. There are sections on installing the systems, deploying the LUNs and recovery. After going through this Redbook, you will have a better understanding of a complete and protected VMware system. If you need help with how to size your hardware there is a section for you. If you are looking to test how to run VMs over NFS, its in there too!
One of the biggest issues with virtual systems is making sure you have proper alignment between the system block and the storage array. This will negatively impact the system by a factor of 2 in most random reads/writes as two blocks will be required for one request. To avoid this costly mistake or to correct VMs you have already setup a section in the book called Partition alignment walks you through the entire process of correctly setting the alignment or fixing the older systems correctly.
Another area that I will point out is the use of deduplication, compression and cloning to drive the efficiency of the storage higher. These software features allow customers to store more systems on the storage array than if they used traditional hard drives. Also there is how to use snapshots for cloning, mirrors for Site Recovery Manager and long term storage aka Snapvaults. At the end of the book are some examples of scripts one might use for snapshots in hot backup modes.
Whether you are a seasoned veteran or newbie to the VMware scene, there is a great guide that will help you from start to finish setting up your vSphere environment. The information is there, use the search feature or sit down on a Friday with a high-lighter, which ever fits your style and learn a little about using a N series system with VMware.

Last week at the IBM Technical Conference I was able to spend some time with a couple of friends discussing technology. It is always interesting to hear their take on where the storage market is going and what lays ahead in the future. As my Netapp pal and I were chatting about the messaging around unified architecture, we both noted that unified to one perceptive is disjointed to another.
IBM and Netapp have been using the term unified for its NAS/SAN device for about 5 years now. The idea is to share a common code base on the same hardware to increase functionality and usability of that storage. Other vendors have gone similar routes using multiple code bases and/or hardware but I see that as a NAS gateway in front of SAN storage system.
This has been very successful in data centers both large and small. But the idea of how we manage storage is changing. Virtualization is changing the idea of how and even where our data may be stored. The term cloud is something of a marketing term but I like the term Storage Utility better. Utility companies such as electric, water, sewer and even cable provide a product to its consumers and storage utility vendors could do the same.
Most people are not concerned about process companies take to make water drinkable or how electricity is generated as long as it is safe, reliable and easy for them to consume. Storage as a Utility is no different, it is only when the storage is offline or hacked in by outsiders the consumers are concerned. There are laws that govern utilities and the FTC has put some privacy laws together to help consumers but I believe we can take it a little further (a blog for another time).
As our data is changing from traditional spinning drives in our data center to a storage utility, we will need some type of bridge that will ease the pain of transition. The main reason people do not adapt new technology is because the transition is often too painful and the benefit of new technology is less than the need to move. Whether it is a software package that helps move data or a hardware device, it will have to give access to both file based data and object based data. This will allow for users to read the files as needed no matter what their connectivity or location. It could also be used to help drive efficiencies up buy allowing data to move from file based (high cost) to object based (lower cost) environments.
Today there are some vendors who have early versions of this type of unified solution. They are bridging the gap between what we have today in private data centers and the future of public utility storage. This is very early in the transition but with this type of technology, we will be able to adapt and provide a better way of storing data. Will it still be called a unified solution? Only the marketing people can tell us that.

May 9th has been a target on my calendar for some time now. Inside of IBM, we have been waiting for this day to come so we could talk about the new things being released in the storage platform. It almost feels like Christmas morning with a bunch of new presents under the tree. Each gift has inside something that is either really cool or something very useful. The only difference is your Aunt Matilda and her little dog is not coming over for brunch.
Under the IBM tree today is a slew of presents for almost the entire storage platform. I will concentrate on just the IBM NAS ones but if you are interested in knowing what is going on elsewhere, you can find more information at the main website.
SONAS must have been a good boy because there are plenty of gifts for him under the tree this morning. Not only did he find presents under the tree but there were a few little things in his stocking. Here is what Santa brought:
This SONAS release is labeled R1.2 and can be obtained by contacting the technical advisor assigned to you.
Santa was also at the N series house and dropped off a few gifts. A new N6270 to replace the N6070. This new system is in line with the N6200 series with larger amounts of RAM and processors. Just like the smaller N6240, there is an expansion controller where customers can add more PCI control cards like HBAs, 10GbE or even FCoE. A new disk shelf was also released which uses the smaller 2.5 inch drives with improved back end performance.
And over at the Real Time Compression house they got new support for EMC Celerra.
Over all a very busy time of year for IBM (and Santa) as these were just a fraction of the Storage announcements today. Also today is the IBM Storage Executive Summit in New York City. My friend and fellow blogger Tony Pearson is covering this great event and will be updating his blog and twitter feed. If you were not able to make it to NYC for the event, feel free to tweet him your questions @az990tony You can also send questions to our IBM Storage feed at @ibmstorage
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.
There is an ancient proverb that says " When you have only two pennies left in the world, buy a loaf of bread with one, and a lily with the other.". There is some wisdom in this old saying that we can still apply to today's IT budget and strategy. If you have been keeping up with the news, you would know companies are starting to invest again in their IT hardware and software. This maybe the turn in some of the hardest times in the hardware business. But what are customers really buying and planning to buy with their dollars?
What is my bread and what is my lily today? The bread represents nourishment of the body. We have to eat in order to keep going. With out it, we starve and eventually die. This would be the basic part of a business IT strategy. What do you have to do to keep the lights on? I have this conversation with IT planners all the time. People love to do the newest and greatest, but have a smaller understanding or take for granted the things they have to do to keep the business going.
The lily is a beautiful and majestic flower. Dating as far back as 1580 B.C., when images of lilies were discovered in a villa in Crete, these majestic flowers have long held a role in ancient mythology. Derived from the Greek word “leiron,” (generally assumed to refer to the white Madonna lily), the lily was so revered by the Greeks that they believed it sprouted from the milk of Hera, the queen of the gods.
The storage market is evolving with the help of cloud storage, unified platforms and consolidation. IT planners and CIOs are dealing with a new way of putting value to these terms and offering their business units a charge back model not only based on data consumption but throughput and retention. The smarter businesses are seeing that running multiple storage platforms with trapped efficiency does not work in today's data center. Storage has to be big, wide and easy to use.
Long gone are the days where 10-25 TB were a big deal. We now see systems that start at those levels and go to infinite proportions. Networks are becoming faster and even consolidated with 10/20 gbps driving protocols like FCoE and iSCSI. Backups are being replaced by better replication algorithms that have quality of service levels and automated failover.
NAS storage can take advantage of these technologies that can also help you keep the lights on. Most businesses have some form of NAS storage to help employees share documents, spreadsheets, images, and what nots. There is a movement from the traditional block based systems to unstructured data sets using NAS and these are pushing the market and vendors to come up with better NAS products. Companies like Amazon, Facebook, Twitter, all push vendors to think about how they do storage.
So how are you planning your IT spending are you going to spend more on things that you have to have or will you spend more on the things that look nice? I suspect in most cases there will be an 80/20 split of bread to lily ratio. But how you classify what is needed and what is 'nice to have' in your IT department will change as your business changes this year. Businesses are putting more demand on IT with fewer resources. Even though there is evidence businesses are spending more the hardware recently, the resources (admins) are still not there. The only way companies will be able to achieve success with such a high demand on storage with out the resources is to have simple, scalable storage that allows single admins to manage multiple petabytes of storage.
IBM is working to help customers achieve this type of new IT department. Cloud is one way, either public or even private, but also from a basic system level. Interfaces that are less complicated like the V7000 or XiV allow admins to move easily with out much training. SONAS offers large scale out NAS storage where storage and throughput can be scaled independently.
This year, take time to figure out what is needed and what will be cool to have in your department. Technology will always change, even if its a change back to what we had 20 years ago (mainframe/virtualization). Keep in mind it might look like a lily today, but will be a loaf soon, where do you want to be when the business needs it.
