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?

If you haven't heard (get from under that rock) IBM is turning 100 this year and the company is having an awesome time celebrating our longevity. From technical advances, the Apollo program to blazing trails through race and gender equality, IBM has and IS doing the job for all of the world. The company has changed in so many ways and has to adapt in ways only IBMers can but we have survived and thrived.
Find more information about our centennial celebration here.
Here is a great 100 second video of all the cool and great things IBM has done over the last 100 years.

How does one judge a glass of wine? There are a few tests, how it looks, smells and taste are the basic three. But as the wine is poured you may or may not know that your wine is made up of different varieties of grapes. A producer sits down and experiments with different percentages of grapes and this allows some creativity in making a better glass of wine for the consumer. Of course there are many more factors that play into this process but its by in large the same no matter what wine you enjoy. You enjoy the wine as a whole, a combination of things put together for you with out you having to know or even understand all that went into making that glass of wine.
When we talk to clients about their data backup strategy, we find a very similar process to that of wine making. The end user rarely knows all that goes in to creating a backup of their data and protecting it for them. They just enjoy the knowledge that their data is safe and will be there if they need to access it. But what we see in the making of the backup is a blend of technologies and a creative element that allows administrators some work around constraints like budget and man power.
As data evolves, we are seeing multiple layers of protection and depending on the severity of the data will determine the recovery point and recovery time as well as retention period. Backup technologies usually mean more than doing a bunch of incrementals and then a full off to disk pools and then tape. There are many different levels of protection that we can use.
Snapshots seem to be more common today than 5 years ago. They allow for a clean and consistent recovery point of a database or file system. But snapshots are used for more than just a quick backup, with writable copies we can quickly setup copies for test and dev environments and also rapidly deploy virtual images for desktops or servers. Snapshots are usually set to the same disk set that data is sitting on, and can be moved around via a vault technology or a mirror to another site. This can be used for long term storage if needed but typically snapshots are used for quick recoveries of less than 7 days. Snapshots are also vulnerable to data corruption. If a software bug comes in and corrupts data on the storage system, that can effect the snapshots and mirrors.
Backups are more traditional where the file system is scanned for changes and then those changes are sent off to a device where the data is stored until needed. In the past it has taken more time to backup file systems and as storage has gotten larger, those backup times grow longer. The technology has tried to keep up with adding larger backup servers and more tape drives allowing for more streams coming in. Now with the idea of using spinning disk for tape pools, we can backup a little quicker as the disk can write data faster than tape. There are many things that have evolved out of this technology, for example Long Term File System or Hierarchical Storage Management.
When clients are looking for strategies on protecting their data, they will use a combination of these techniques, and a mixture of both disks and tape to fully protect their environment. Depending o the data type, you may want to just use snapshots as the data changes rapidly and you do not need to restore from a week or a year ago. Snapshots are really useful in the case, and so is mirroring or even metro mirroring if the RTO is small enough. There are other factors such as Sarbanes-Oxley that will require longer term recovery methods like backups.
Just like a great wine, there is fewer rules today and room for creativity in designing data protection. And just like wine, there are many consultants that will help you find a good balance of technology to match levels of protection with data. Spend the time looking at your protection schemes and see if there are any better ways of balancing this equation. Maybe, with the right planning, you will be able to enjoy a glass of wine instead of spending time recovering from a disaster.
One of my favorite TV programs is the BBC show Top Gear. They go through and test cars not only for handling, looks, and cup holders but mainly for power. At the end they run all of the cars through the same test track and get a time. That time then gets recorded on their list of all the cars tested and is celebrated for achievement or scorned at for doing poorly. No matter what the car turns up, they were all treated equally.
Today, IBM is announcing a test done by a certain benchmark called SPECsfs. This has been the yardstick for all NAS vendors wanting to flex their muscles and show how they handle small block I/O. Vendors can bring how ever many drives and tweaks they want but the test itself is very rigid and has to be certified before the results are published.
IBM put together a SONAS system consisting of 10 interface nodes and 8 storage pods with all SAS disk. A total of about 900TB of usable disk, and about 1/3 of the maximum SONAS configuration. There was no solid state disk or extra tweaks done just a SONAS system that you could order today. That said, the IBM SONAS set a new world record for performance for a single file system at 403,000 IOPS per second.
Yes you read that right, 403k IOPS in a single file system. If you look at the other vendors they have used multiple file systems to aggregate the performance together in order to achieve a benchmark. Then they tend to use a virtual name space with software that is layered over all of the file systems, but here SONAS is one file system over 900TB with a true global name space. Some issues with multiple file system is they cannot stripe data across the file systems and the load balancing becomes an issue. If you look at the comparison of performance per file system, you can see that IBM is WAY beyond the competitors.
So you maybe asking, "Yeah that's pretty cool but what was the response time?". According to the test, the average response time was 3.23 MS from 0 to 403k IOPs per second. This is extremely good and when you think that was coming from one file system of 900TB, you realize how good that number is compared to other results.
There will be tons of vendors trying to debunk how IBM out performed them and how they have better software or better market share but it really boils down to these key points:
I have included the slide deck for the announcement below. Feel free to check out the information on the SPECsfs website.
I was driving into the IBM Almaden Research Center and just enjoying the beautiful scenery of the San Jose area. The campus is on top of a hill and surrounded by farm lands. I would really like to have a corner office here, but I don't think I would get much done. So here is my Vlog for this morning and I am hoping to get some interviews on here from some of the presenters and attendees.
Day 1: Today, IBM has massed the troops together to learn more about the SONAS product and how the product will look in the near and far future. There is a ton of information they are dumping that I need time to just process it all. Its also nice to meet people from all around the world that have the same mission as I do. I hope to get some interviews tomorrow as well as listening to Sven Ohme talk about performance of the box.
This video is shot in front of the first hard drive, ever. What a testimonial to the IBM innovation. The first words written are..... you gotta watch to find out.
I am headed out west to learn more about SONAS and the future of the product. I think there will be lots of good information that I will try to share with you. If you have any question that you want to ask a SONAS developer, let me know as they will all be there!
Today IBM is releasing two new N6200 systems that will be a huge improvement over the existing N6000 systems. The two new systems will show a bump in capacity and performance and more flexibility. For a very crowded midrange market this new N series product set will bridge the gap between entry level and enterprise class systems
The first thing that stands out to me is the footprint of the new system. The older N6000 has a 6 U requirement for an HA pair. The new N6200 is half the size, only occupying 3U for the two HA pair, or a single node with a I/O expansion module, providing an additional four PCI-e cards. Another configuration is two controllers with two expansion modules in a total space of 6U (equal of the older N6000 systems) but with a total of 12 PCI-e slots (vs 8 on the older N6000).
We will recommend using the two slots built into the controller for high performance 10GbE and / or 8 Gb PC adapters. The additional expansion slots in the expansion module can be used for Flash Cache and other connectivity for disks.
The on-board hardware is getting an face lift as well. While the new system sports a 10GbE port this is used mainly for the interconnect and nothing else. This was one of the disappointments I have with this systems, but understand this is how Netapp will accomplish scale out clustering.
FC ports were kept at 4 Gbps but there is two new SAS ports with matching ACP (alternate control path) ports used for off loading some of the traffic from the data path.
One of the unsung updates was in the NVRAM. Instead of using the same memory in the past, we now see an improvement of the memory by using something called Asynchronous DRAM Refresh (ADR). This is a new self-refresh mode in the Intel chipset that allows a portion of the main memory to be backed by an on-board battery. This gives the NVRAM the same high bandwidth as main memory and also simplifies the design of the motherboard.
This gives the new N6200 systems a bump in performance along with the introduction of the new Intel processors. The SPECsfs benchmark on the highest N6200 system showed 101,183 ops at 1.66ms ORT compared to the N6060 showing 60,507 ops and 1.58ms ORT, an improvement of about 70% in SFS throughput.
IBM is introducing the IBM System Storage N6210 Series and the IBM System Storage N6240 Series These new systems replace the IBM N3600 and N6040 Series respectively. GA date is scheduled for January 28, 2011 (N6240) and February 25, 2011(N6210). Here is the slide deck that is published with the release.
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.
