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.
If there was ever a time for IBM to look at the storage market and come up with a product, today is that time. IBM released a new storage platform called Storwize. If you remember, IBM acquired another business named Storwize but the two do not have anything in common. It's a cool name and I am glad we got to use it!
There is a ton of information coming out about the product and what it can do and how it will help you, but I wanted to take a little different approach to the announcement today. I am going to be doing some live blogging and tweeting about my journey to the announcement in New York City. I will be trying to help everyone who can not make it get a feel for what is going on and hopefully be able to interview some people along the way.
As for now, I will be putting up some video blogs (Vlogs?) and tweeting. If you don't follow me, my account is 'richswainWORK'. IBM will also be using the #ibmstorage hash all day to keep up with everyone's comments and questions so fire away, we have a staff of people just waiting to help.

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.

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

I have closet in my house that I keep all kinds of computer gear. Most are things from some fun project that I was working or a technology that is past is prime. There is everything from Zip drives to coax termination to a Ultra-wide scsi interface for an external CDROM. Why do I keep these things in a box in a closet? Great question that usually comes up one a year from some family member that sticks there head in there looking for a toy, coat or looking to make a point.

Just a quick drop on the Data Reduction Tool that we use in the field to help estimate how much storage customers will save by running their data on our A9000 All Flash Array. This system (not SSDs) is based on the XIV Grid architecture and is available to customers since this past summer.
One of the things that many of our customers tell us is our competition is out offering silly data savings only based their word. IBM has for the past 5 years giving customers a real estimate on their compression savings using our compression estimation tool within 5% with out change to your code or storage system. Now we have the ability to run the tool on your data for savings on our compression, deduplication and pattern analysis.
This tool is downloaded from the IBM site and run on the host against the storage lun/volume. At the end you will be able to see the savings broken down in those three categories plus how much could also be saved using thin provisioning. The tool is CLI based and should be run by an admin with proper access.
All said this tool is the best thing out there to really give customers an idea of true savings. For more information please follow these link below
For more information about the tool or help running it feel free to contact me or your local IBM Storage Engineer.
I am always blown away with the expertise and insight our Advanced Technical Services team displays. They are our “Go To” guys for driving technology to our field teams and they are the last resort before getting into a development team. For me, they are a well of information and experience that I can use to help build solutions.
Today, I am sitting in the SONAS system training with Mark Taylor. Mark and I have been working together at IBM for a few years and I have the most respect for him. Mark is responsible for supporting the N series and SONAS at IBM along with a few other team members. He has is known for being a stickler on our solution assurance calls and is always finding solutions for our clients.
Our mission this week is to learn more about storage products on a deeper level. Many of the technical sales group has specialty that they focus on. It could be XiV, SONAS, Mid-Tier storage, what ever. This week, when we leave on Friday, we should come away as more rounded technical experts.
I am still amazed at the SONAS product and how powerful it really is, especially compared to other products in the market place. I find it hard to compare to other brands due to great feature set it brings and integration with TSM. No other storage out there is able to provide unstructured NAS data a platform to live on from cradle to grave like SOANS.
This mimics how IBM is doing more solution selling in the marketplace. Our Storage team is partnering with the POWER team and the Software teams to provide customers with a ‘one stop’ solution. If you look just at the SONAS product, it has multiple components all from IBM; X series servers, TSM and GPFS software, XiV storage. We are finding that if we combine these products into a solution based product, customers can solve more issues with the same amount of dollars. I believe this is the future of IBM storage and storage in general.
SONAS does have a couple of points that I would like to see cleaned up. One is the GUI, and the other is its policy writer. From what I can tell, the information in the SONAS GUI is very similar to that of the XiV system. It just has a different look and feel. With the Storwize V7000 getting the ‘XiV’ look and feel, I suspect future releases of SONAS might get the same treatment. As for the policy engine, it’s all based on SQL Query language. If you know how to write it then it’s not an issue but there are some out there that might not be privy to such skills. There are some guidelines and examples that can be used to help setup the policies like moving data from one pool to the next but I suspect people will rely more on their Technical Advisor to help define those rules.
Tomorrow is all about protect tier. I am excited about the hands on and finding how this box can really save people space with their backups.
Well the last two days have been crazy with really good sessions, lots of networking with tons of people and great discussions throughout the entire conference. The sessions have been well attended and people are really asking great questions. For the most part, I hear that everyone is learning from the sessions, which I hope they dont get overloaded with so much information.
Today I presented on PAM II technology for the N series system. We disussed the need for large Read Cache systems and how its not only the size of the disks that are driving this need, but also the business requesting for lower return times on data. During this session, the question was brought up about the new acquisition of StorWize and how that would effect the NAS solutions at IBM.
Here is IBM VP of Storage, Doug Balog, talking about the product.
I think its going to be a good product to put in front of our NAS systems and it will drive the heavy read cache systems like PAM II and the huge amounts of cache in the SONAS systems. Speaking of StorWize, I wanted to give everyone a little more information about this product and maybe why IBM purchased them. They provide real time compression technology that will reduce the storage need by compressing the data into images. They have an engine called Random Access Compression Engine (RACE) which is just a compression algorithm that does the conversion with no overhead. The Storwize appliance will work with popular NAS systems, including IBM N series and SONAS, as well as non-IBM NAS systems from EMC, HP, NetApp and others. Storwize real-time compression can provide added value to clients already using data deduplication, thin provisioning and other storage efficiency technologies.
For more information on the StorWize acquisition, go here for the press release.
There is always a part of the business that gets over looked and usually its the people that are in the trenches making things work and keeping those machines going. I recently had the pleasure of spending some time with three great IBM CEs here in the Raleigh NC area. I was impressed with their professionalism and thoroughness while working on the SONAS upgrade. They made sure everything was installed, cabled and tabled according to the documentation. It is one thing to have a great product and lots of features, but it is even more important to have people who can service the system and do it with the highest level of craftsmanship. Thanks guys and gals for everything you do to help make our job easier!
Today, I helped our local Client Engineers install a couple of new nodes and some more storage into a local SONAS system. This was exciting for me as I love working with the hardware and software and it keeps up my keyboard skills. This client is bringing online more demand and needs both horsepower (interface nodes) and storage to accommodate a new business line. I was amazed at how easy the system is to upgrade and soon his little starter rack is almost full.
We added two interface nodes, IBM xSeries 3650 m2 and two 60 disk shelves to the unit. Once the disks are online and presented up to the interface modules, they can start creating shares for the new operation. As they need more storage or more interface nodes, another rack will be but in and the same process of pooling these resources together will come together.
The idea of having multiple interface nodes and storage pools is to not have single points of failure. In traditional storage, if a controller goes down, its partner has to pick up the entire work load for the down hardware. Not so in SONAS, if a controller goes down, the work is then evenly spread across all of the other nodes in the system. This is why we do not have a problem of loosing CIFS connections when systems go down.
The addition of new storage is also interesting as we are tripling the amount of storage the base system had originally with two 4 U shelves. These shelves are highly dense, top loading containers using either SAS or SATA disks. In this instance today, we were installing 120 2 TB SATA drives. A total of 240TB in 8 U of space. Not too shabby.
At the end of the day, I was pleased to see that IBM is moving forward with smarter storage systems. If you look at the entire portfolio, you can see that our systems like XiV grid, the auto tiering on DS8700, SVC virtualzation, all of these systems are helping our goal of a Smarter Planet. Look for some more pictures and maybe a video on Monday.
I was on my way down to Miami today and was talking to the gentleman sitting next to me about storage technology and the conversation turned to how everyone is scrambling to be in the cloud business. He had heard multiple vendors come in and start talking about cloud technology and how it was going to save him money, time and effort. This gentleman worked for a retail chain that has multiple district offices through out the eastern US and headquarters in Atlanta. He has multiple technologies all helping him keep the business running but nothing planned and as the company grew, they simply cookie cut the previous installation and planted it into the new office. Each office would also replicate back to HQ and that would be the main repository for backups/restores. I would guess there are thousands of companies out there with similar setups.
So instead of going into how he could leverage cloud storage technology, I asked him what were his problems and listened. They basically came down to this:
1. Multiple independent islands of storage that are aging, causing his support contracts to go up.
2. Backups take way to long and systems are slowing down as they get closer to 'capacity'.
3. Future growth was expensive as every time they added a new capacity, they had to add entire systems.
Now they were not cutting edge technolgy leaders nor were they wanting to be, but he needed a way to solve some of these traditional storage problems. He didn't want to go out and buy a new large system that would take forever to get in and while it may solve his problems, it would bring in even more issues. What he needed is less overhead and more throughput.
We sat there for a while thinking, we didn't say much until I offered this tidbit, "So what does cloud mean to you?" After a nice laugh, he stated that he really didn't know and the more he read, the more 'cloudy' became the answer.
There are many interpretations about what cloud really is and it differs between storage vendors. If there is a true declination of what cloud storage really could be, I think it could be defined using NAS technology. NAS lends to be a kinder and gentler protocol set and the need is growing leaps and bounds. Our traditional way of adding more systems and creating more independent silos works for smaller environment but it does not scale when clients want large disk pools of storage under one umbrella. There are ways of making volumes span in to large pools but the underlying storage is still made up smaller components that are typically active/active/passive nodes, even the best load balance will not help if you are overloading that system.
There are ways to find a balance between the same old way and going out and dropping tons of cash on huge storage gear. Find a system that will grow and scale as your storage needs do. Think of ways to keep everything under one umbrella (name space for example) and also try to solve issues that you are having today with real technology and not work arounds.
With NAS technology, we will always be at the mercy of the backup target whether its disk or tape. No matter if we are taking snapshots or ndmp backups, we have to write that out to some target to have a restore point. This is your basic strategy on how to do a backup/restore, why not consider using different types of disks to create a tier and offload disks to slower pools as the data gets 'older'. A few vendors have said there is no need for tiering, mainly because their systems can't take advantage of this and therefore they shun those who do. ILM tiering can help you achieve not only higher utilization rates with the storage but it puts the data that is accessed more frequently on faster disk, and moves the rest away to makes more room. Why pay for fast disk if the data on it is not being accessed frequently?
Future expansion has always been tough for administrators, they tend to over buy on controller size and skimp on the disk. Systems like SONAS from IBM allows you to grow both in storage capacity and server throughput; independently. If a customer needs more storage but doesn't need the additional throughput, why force him to add more controllers? SONAS systems can scaled up to 30 storage servers and 14.4 PB of spinning disk all under one name space. No more having multiple nodes with their own names; this storage is called Accounting1, Accouting2 .... etc. They are called Storage and everyone gets the benefit of having all of the nodes, not just one system.
By the time we had gone through all of this, our flight was landing. It was a great talk and both of us gained a different perceptive on how cloud is perceived. If any of you want to find out more information about the IBM Cloud strategy or SONAS go to the following links:

Who doesn't like getting something free? IBM is offering customers the chance to grab some more flash storage by offering a flash drive at no charge with the purchase of two flash drives on new Storwize V7000s or V5000s. There is a maximum of 4 drives at no charge for the V7 and 2 drives at no charge for the V5. What does this really mean? Since a V7 can hold up to 24 drives in a controller, you will be getting automatically a 25% free upgrade while only paying 75% of the total (24 drives) purchase cost.
The drives sizes for this deal are the 1.6TB, 1.9TB and the 3.2 TB eMLC Flash drives. This offer is only for new systems and does not apply to upgrades and only up to December 26, 2016.
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!
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.

Natural disasters such as earthquakes, floods and hurricanes all have at least one thing in common, it makes companies look at their DR plan. This scenario plays out something like this:
CIO texts IT person in charge of keeping the company running "Hey, just checking to make sure we are ok in case this hurricane hits us???? :)"
Reply "Yeah, but we can just move stuff around to the other datacenter and we have most of it in the cloud, we are headed to the bar for hurricanes, come join us!"
Having a DR plan is only as good as the last test. When I was starting my IT career I had to help put together a DR plan and the go to the offsite location to test it. This was an eye opening/watershed experience for me as I learned not everything you write on paper can be done in the time you actually have. I can still remember thinking we could restore from tape all of the databases and backup libraries in a few hours and be back up and running. My test plan was flawed because I didn't:
a. Understand the business needs (SLAs
b. Have input from different IT sectors (network, directory services, databases, backups, etc. )
c. have a plan b, c and d
Now we have the ability to claim our data is safe because it's "In the Cloud" and that does take some burden off the IT department but in reality the onsite infrastructure still has to be able to connect to the cloud. We also have replication of everything which lowers our downtime and keeps things more in a crash consistent state. VMware allows us to move servers from one data center to the next and we are more accustomed to keeping things up all the time.
This scenario of up all the time still doesn't excuse us from not having a DR plan and testing it. If you rely on the software to make sure your business is always up and running you need to understand the processes it takes to get the software up and running. There is something I have heard people use more and more when describing large down time problems "The Perfect Storm". This is where a process is not understood or taken in consideration when keeping the business running. For me when I was younger this was the fact we needed to have a directory service restored before we can start restoring servers. I didn't understand the primary need to have ALL of the users/passwords for the servers before they restored.
I hope everyone in the FL/GA/SC area stays safe and have taken all of the necessary precautions for their homes and businesses to stay safe. Good luck and God bless you all.

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?
Do you expect more out of your storage? IBM thinks you should and is putting their money where their mouth is. In the past it has gone under different names like STG University and Storage Symposium, but now IBM has revamped its premier storage conference. The big announcement came today with much fanfare that included a new website, some videos and bunch of hype on twitter. A three part conference for executives, gear heads and business partners there is something for everyone. But what will be different tham years in the past? I think IBM looked around how other vendors use conferences to help pump up its customer base (VMWorld, EMCwhatever) and decided to put some hype in the conference.
Think of this as a great place to go and network, learn and have a good time. The conference will be in Orlando and there will be tons of time to sit in class rooms and learn about the latest technologies but there will be sessions where IBM will be pulling in our top execs and analysts to tell you where IBM is going in the storage world.
The Executive Edge will feature different speakers from Jeff Jonas, Aviad Offer and IT Finance expert Calvin Braunstein. This track will take executives through new announcements, deep dives on technical platforms, one on one sessions with IBM Execs and some great entertainment. This is a new feature of the conference as in the past it was more geared towards the technical teams.
Of course the Executive Edge will be limited so talk to your local storage sales person to get a chance to be a part of this special event. There will be time to bring in your team and have special sessions and round tables with the IBM engineers who can help you find your way down this path of crazy storage growth. And there is a golf course on site which I have heard is very nice. Bring your clubs or rent them, I am sure there will be plenty of us out there so find a partner and have a good time.
More importantly IBM is making the effort to step up the event and have it on par with the other IBM conferences like Pulse. The technical portion will have over 250 sessions on storage related topics. You will also get road-map information from the product teams as well as a chance to become a certified technician. One area that has been expanding is our hands on labs and this year we will have the biggest one yet. You will be able to come in to the labs and actually see our storage systems and have a chance to 'test drive' them.
Early bird registration is open now
and you can sign up today. The conference will be in sunny Orlando
Florida at the Waldorf Astoria and Hilton Orlando at Bonnet Creek. The
event starts on June 4th and runs to the 8th. You can follow the
conference on twitter @IBMEdge and use the hashtag #ibmedge For the conference website go here
I look forward to seeing you in June.
It is announcement Tuesday here at IBM today and the V7000 is not releasing a new feature but has a package that will be helping customers greatly. This is not a NAS box, but I have been following the progression of the development for the V7000. IBM Storage announced today a new package of both Hardware, Software and Services to help enhance the Storwize V7000 system.
The hardware doesn't change but it will include both IBM Tivoli Storage Productivity Center for Disk Midrange Edition and IBM Tivoli Storage FlashCopy Manager to help round out a complete set of software functions. This is a very cool way of putting together a suite of software that makes sense for this platform. Much like the N series SnapManger suite the flash copy manager can take consistent backups/snapshots of databases and the like. TPC is a monitoring tool that allows admins to view data both historical and real-time.
Another part of the package is IBM services that can come in and help customers with the setup of the hardware and software. Customers are always wanting to bring in new gear and get it up and running as quickly as possible and IBM has the engineers to do just that. This service will provide planning, implementation, configuration, testing and basic skills instruction to help you eliminate the need for in-house resources skilled in the technology and free up your IT staff to focus on other higher priority business initiatives.
This package is not a way for customers to get their V7000 up and running but its a way to monitor and make the system more efficient. The V7000 already has a long list of features that we have taken from our enterprise storage and now we have the tools and means to help make this solution even better.

There is a demo coming up on January 20th that will show the integration of N series and VMware. The long awaited Virtual Storage Console and Rapid Cloning will be the highlights of the demo. So what is VSC? It is N series software that enables administrators to manage and monitor storage side attributes of ESX-ESXi hosts. VSC functions as a plugin to vCenter and uses APIs to set and retrieve information from the array.
VSC adds a tab into vCenter and enables the following:
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.
IBM released a new Data Ontap version last Friday along with some other minor releases but more about those later. Data Ontap 8 7mode was the first release of a new 64-bit architecture that will allow N series customers to take advantage of larger aggregates.
A little history. Back about 8 years ago, Netapp purchased a company named Spinnaker for the use of their 64 bit code, global name space and some other odds and ends. For the most part, Netapp has been re-branding this code as their GX platform allowing customers who want the feature set to purchase it aside from their Data Ontap base. GX was not a heavy seller as it was complicated to install and much more pricey than the other brand and Netapp decided to co-mingle the two code streams into one. At first glance this sounds like a good idea. The Data Ontap code definitely had some limitations (small aggregates sizes, limited growth and no global name space) but the merging of the two streams was harder than Netapp imagined. This was shown by Netapp promising a release of the new merged code for over years and finally a release was available for testing.
There were many bugs (as RC code can be) but Netapp worked through the majority of them to produce a stepping stone release of the merged code called 7 mode. The developers used bits and pieces of the GX code to get the 64-bit architecture allowing customers to build larger aggregates, up to 100TB in size. This was really important as the release of the 2 TB Sata drives were coming and the limitation of 16TB in an aggregate would of killed any performance on the system. With only 8 2TB drives in the aggregate, the maximum IOPs throughput would be limited to about 400 IOPS per 16TB of drive space, not a good ratio at all. Therefor having a larger aggregate size allows them to put up to 50 2TB drives achieving a more respectable 2500 IOPS per aggregate.
Now that we have the 7 mode available, there are some upsides and some downsides. First, as stated above, the aggregate sizes have increased tremendously. Allowing for more data disks in the aggregate increases the amount of IOPs the filer can pool. On the downside of this news, we see that you can not simply flip a switch and increase an aggregate created in the old 32-bit code to a new 64-bit aggregate. Customers will have to create a new aggregate after upgrading to the 7-mode version of Data Ontap 8 and then migrate with some restore method (think DR restore from backup) on to the new space. You can not mirror the two as SnapMirror can only mirror between like for like aggregates (32-bit to 32-bit and 64-bit to 64-bit). No big deal if you are new customer or if the filer is a new addition to the filer farm, but for those existing customers I believe this will be a lot tougher. If you do not have the drive space to create a new 100TB or less aggregate, you will have to either wait to buy more disks or do a manual backup (not snapshot), destroy the existing aggregate, and build a new aggregate on the 64-bit code, then restore. This is and the fact this is the first release of the new code family, will be why customers will not adopt the new code very quickly.
There are also some other gotchas like no support for Performance Accelerator Cards (PAMII), no real interoperability between the two code bases and more. When I was an administrator, I hated having to read the release notes for the 'fine print gotchas' but in this case I encourage everyone to read the notes thoroughly and perhaps engaging your local IBM Storage engineer to help you access if you are a good candidate to upgrade or not.
The fact this is a stepping stone to the full code line does help customers that need to move to the 64-bit architecture today without slowing down Netapp's development team. They are working on the next release of Data Ontap 8 called cluster mode. This will be the code that allows customers to cluster more than one pair of systems under one global name space. I suspect this will be a great addition to the Data Ontap code line and will give Netapp more traction in the larger enterprise business.
There were also some firmware releases for the EXN3000 shelf on Friday as well. For more information on what was released, visit www.ibm.com support page
The old adage of faster, smaller, cheaper has been revived in the N series product line. This week (officially) IBM released the information around the highly anticipated OEM re-brand of Netapp's FAS 2040; the N3400. This system has a small 2U form factor but delivers higher performance than its beefier brother the N3600. If you want to see a full comparison of the three boxes, click here for more information.
IBM has three systems that round out the entry level or departmental storage platform. The N3600, the N3300 and now the N3400. All three are based on internal drives with some expansion to a few shelves as needed. The N3600 comes with 20 internal drives and the smaller N3300 and N3400 comes with only 12 internal disks and can expand to a maximum capacity of 136TB. There are two controllers that allow administrators to have a high availability solution for low cost. This makes the system more attractive as it also supports FCP, iSCSI, CIFS and NFS all from one platform.
The N3400 does have a few things I want to point out:
All of these help set this box up for an important role within your datacenter. If you compare this system with other storage systems in the market, you find the new N3400 is well stacked and can compete even with larger mid-tier systems. This box is ideal for our SMB clients who really need the all in one system with the horsepower to keep up with a growing company. The system is a long way from the first entry level system IBM decided to roll out, the N3700. If the two were to be compared the N3700 would be a 'Happy Meal' and the N3400 would be a super sized 2lb Angus burger with fries and shake, maybe even an apple pie.
This new system is considered ideal for both Windows consolidation and virtual environments alike. With the additional ports the system does leverage a larger life span as the new EXN 3000 SAS shelves are becoming more of the standard for the N series product line. The system on the other hand does not support 10GBPS cards or FCoE as the N3600 does. But as all N series systems support the same Data Ontap code, the robust system uses the same commands, interface and is built on the same technology as the other N60x0 and N7X000 lines.
Overall, this is an enhanced refresh of the exisitng N3300 with more ability to scale with currently technologies. The performance will be more than the N3600 which begs the question of the need for the N3300/N3600 systems. I suspect as Data Ontap 8 becomes general available from Netapp, there will be more entry level storage devices released.

Move that File! You know that show were people are moved out of their old house, an army of contractors come in and build a new house, then the people come back and are astonished at their new home. I was watching an older episode the other night and released how much this improves a family's mobility, productiveness and state of mind. While, their old house was ok, it provided some what of a shelter, the new house was 100x better.
I think of SONAS in the same way. There are many ways to do NAS technologies. Some take time to develop and build, but others are just as effective with little to no planning. I was talking to a client the other day and his response to NAS was to put NFS servers in all of their locations. It's cheap and something they can repeat like a cookie cutter many times over. What he was not taking in to his planning was administrating all of these islands of storage and how much he was spending on data sitting on expensive disk. If he was able to consolidate these servers and have a way of moving data around and eventually off to the greenest storage media out there, tape, then how much more money and time would that save him? He didn't have an answer but we are working on plan for him today.
IBM announced yesterday that SONAS version 1.1.1 will now support ILM tiering with GPFS and then moving data off to tape using Tivoli's Storage Manger HSM. These two work in concert with the policy manager on the SONAS system to move data on and out of pools based on the meta data properties. As discussed in previous posts, SONAS separates the meta data which allows the scan engine to pass the needed data on to the ILM or TSM agents. These agents then move data between the pools and allows the client to free up space on valuable spinning disks.
If you are one of the people that says tape and tiering is not needed, then think about the idea of putting data that hasn't been touched on a disk that costs $0.03 per GB. Its not that your storage isn't cool and you may not need tiers for your high performance, but what if the only data that was on the system was data that was actively being used and not my old spreadsheet from 2009.
Along with the ILM announcement, IBM released the following with version 1.1.1

Every year IBM puts on a conference for all of our clients, business partners and strategic partners.
All this week I will be attending a training event at IBM called Tech Fest. Kind of Comic Con meets IBM Storage University. Technical engineers from all over the country descend upon Washington DC (ok it’s really Gaithersburg) to learn about IBM Storage.
The goal is bring everyone up to speed on the latest products coming out of IBM Storage: SONAS, XiV, DS8800, Storwize V7000, etc. A pure technical deepdive with the R&D teams to get a better understanding of the new storage and features.
Training is essential to keeping a sales force moving forward. Not only to present new ideas to clients but to solve those issues that has been around for years. With out training, people are forced to pick and choose their products they get up to speed on and with a large portfolio of storage at IBM, which can be a huge undertaking. I for one try to keep up with the NAS systems and that is a never ending saga.
One idea I have had in the last few weeks leading up to this is how to simplify the entire IBM Storage portfolio. We have a ton of products that have great features but they seem to cover a certain area in the data center. You need storage virtualization, we have a system that can do that (actually two now with Storwize V7000). You need a high performance box built on all sata technology? We have a system that can do that too. I was really hoping the big wigs at IBM would start simplifying the product line and have the systems be more universal than they are today.
We have a good thing going with the Storwize V7000. If we could put NAS technology in that system, and integrate the XiV interface into our products, we could start simplifying our products. We should have a low end storage, mid and enterprise storage all based on the unified platform. I am sure we can do this as the products are mostly based on commodity parts, it’s just the software integration.
There are definite advantages in simplifying the product line and I bet we can work towards that goal. Besides sales, support and development can be simplified and improved as there would be fewer things to learn. I think there are lots of benefit and some risk.
So this week I am going to be talking to lots of people and getting their opinions on IBM Storage. If you want to follow me on twitter, subscribe to richswainWORK.
I am at the IBM Storage University this week with the hope to spread the good word about NAS technology at IBM. The opening session was awesome and SONAS was mentioned a couple of times as part of the IBM Storage strategy. Listen below to a few remarks (short clip) from IBM VP Storage Doug Balog.
My session on NAS technology was well attended and people asked thoughtful questions. We talked about the N series and a couple of new features we have been adding through out the year. Then we talked about the SONAS platform which I think is one of the hottest topics being discussed here this week. I also worked in the solution center where all of the vendors setup booths even Netapp, who is a platinum sponser came with a very large booth this year, right at the door. I didn't get a chance to talk to that team afterward but I hope they were able to speak to alot of people here about N series.
I had a ton of people coming by and asking about SONAS, and not just what is it, but how can it help them.
Today there are some great sessions that I am hoping to attend. One is a N series client from IBM talking about Managing the Largest AGFA PACS solution in the Americas. Then there is my session on ILM/HSM in the SONAS system. I am hoping we will have a great turnout for that ! There are so many sessions that I want to attend, I need to clone myself so that I can get them all.
IBM Storwize® V7000 Unified stores up to five times more unstructured data in the same space with integrated Real-time Compression
IBM Storwize® V7000 Unified stores up to five times more unstructured data in the same space with integrated Real-time Compression
Today IBM announced the enhancement of compressing not only block data on the V7000 but also now it includes the file data on the V7000 Unified. The V7000 was first set up with compression back in the summer with a big announcement surrounding “Smarter Storage”. This optimization was the same code and engine that was purchased from a company named Storwize a few years ago.
IBM initially kept the compression appliance that Storwize was first known for in the market. Using LZ compression with a RACE (Random Access Compression Engine) providing an optimized real-time compression without performance degradation. Thus slowing down data growth and reducing the amount of storage to be managed, powered and cooled.
The compression does not require the compression or decompression of entire files to access the data block. The engine will compress and decompress the relevant data blocks “on the fly”. As data is written the RACE engine compresses the data into a smaller chunk and its 100% transparent for systems, storage and applications.
The V7000 Unified can now deliver a larger compressed platform than any other mid-range platform. With compression percentages around 75%, a system that was maxed out at 2.8 PB (960 drives x 3TB each) can now see the system handle up to 5 PB of storage.
Each V7000 Unified with code base 6.4 has the option of turning on a 45 day trial of the compression software. After setting the license to “45” then you can add new compressed volumes on the system. You can also compress data on virtualized storage arrays.
Compression has been part of NAS for a very long time. We have seen compression of files from jpeg to office documents. But the best part is the end user will never have to worry about which files needed to zipped or compressed. Everything that comes through the V700 Unified can be compressed in line before it writes the data to disks.
A couple of other improvements that IBM announced were the addition of a integrated LDAP server to V7000 Unified. This now allows customers to use both local authentication and external authentication servers to allow access to data. Another feature was the ability to upgrade a V7000 to a V7000 Unified in the field. If you currently own a V7000 but need to add file access to the system, IBM will sell you the two file modules and corresponding software to upgrade you system. Now mind you there is a list of requirements that will need to be met so check with your local storage engineer for more information. And finally we now have support for a 4 way cluster on V7000 unified. This allows for more disks to be provisioned and can compete with some of the other mid-range storage platforms in the market.
This all together makes a nice round of improvements that will make life easier for IBM customers. As the V7000 platform matures it looks like IBM is putting their money where their mouth is and making storage smarter and more efficient. More to come on this platform as I suspect we will see bigger things down the road.

I was fortunate enough today to talk with a great engineer from IBM about his experience at IBM Tech Fest, Keith Thuerk. Keith is based in the South East and is a FTSS (SE) for IBM and has been helping clients find IBM storage solutions in his area for over two years. He has a strong background in networking and works hard on finding solutions that are creative and fit customer's pain points. This week, Keith and other engineers from the East came together for technical training on IBM storage.
Keith and I talked about training and how important it is to keep up your skills. We also chatted about how social media is changing the marketplace.
Keith is also a blogger for IBM and is tweeting information about IBM storage. You can find his blog, Data Center 7.0 here and follow him on twitter, @kthuerk
Here is the audio file from our conversation.

The last day of techfest, I was able to sit down with another FTSS from the IBM Storage team. Neil Youshak is a FTSS that covers the south Florida territory (and more). Not only is Neil an awesome engineer, but he is a triathlete and swims with sharks. Thanks to Neil for the time and look for more interviews soon.
Labor day has come and gone and so has all of the holidays between now and Thanksgiving. This is only augmented with the hope that your favorite football team (both American football and what we call Soccer) has a great weekend match and you get to celebrate with the beverage of your choice.
During your work-week, which can and sometimes does include weekends, all you hear is no more money to do the things you have to do to keep the business running. If you have kept up with squeezing more out your systems with virtualization that’s great but your network is now overtaxed. The staff that used to take care of certain aspects of the day to day running of your data center has been let go and their job has been ‘given’ to you with no thought of compensating you for the extra tasks.
The Earth is warming, the weather is out of control and the price of gas is so high that you decide to bike to work to help save the planet. You spend more time on the road commuting and look like you need a shower when you get to work after dodging traffic all morning. Your coffee is priced higher now because the coffee house wants to use Fair Trade coffee from farmers in a county you have never been. And your dog is on anti-depressing meds because you are not home as much and he can’t go out in the yard because of the killer bees migrating north from Mexico.
Our lives seem to be getting more complicated and it’s nice when we find things that not only help us but are easy to use. When you come across these items they make such an impression that you like to tell others about your great fortunes. I came by a solution that was very easy to use and the value was so great that at first I didn’t believe the whole story.
About a year ago, I was asked to help out on the Storewize/Real Time Compression (RTC) team as it transitioned into the IBM portfolio. I met with the engineers and sales people and all had wonderful things to say about the technology. I listened but was hesitant to drink all of the kool aid they were pouring.
A year later I am very much a believer of the RTC technology and think it really could be a game changer in the market. If you keep up with IDC, Gartner and the other analyst, they all point to compression of the data as being one of the larger items for handling future growth. There are a lot of vendors that claim they can compress data but it’s not all done the same.
One of the things that stood out from day one is the idea of using LZ compression in real time to compress data instead of deduplication. Coming from a N series (*Netapp) background I understood how deduplication works and where it was useful. But this was compression which is a different ball game. Now we are able to shrink the storage footprint that wasn’t exactly the same as before. Given that Netapp has issues with block size and offsets, this is exactly what is needed in the market.
The next question I always get and one I had was “That’s great, you can compress data with the best, but whats the overhead?”. I waited a long time to see what the performance numbers were going to be and found an astonishing outcome. The RTC appliance made a performance improvement on the overall solution. It does help by adding cache and adding processing to the serving of data but it also improves the performance of the system by having to process less data.
For example, if a system has to save 100GB of data with no compression, then all of the data has to be laid out on the disk, that sping for 100GB of data, cache, CPUs, I/O ports all have to work harder to save 100GB of data. But if we get 2:1 or 3:1 compression ratios, then all of the components have to work less. No longer are they working to save 100GB of data but 50GB or 25GB or data. This allows the system to process more data and have cycles to respond quicker to I/O requests (IE lower latency).
So the final thing is always the question of how hard is this to install. Is there a period of time that you have to wait or have 5 IBM technicians to install it. All I have to say is its easy. So easy that there is a good YouTube video that goes through the entire process of unpacking to racking to compressing data. I think the video speaks for itself:
So if you are back at work today and find your life swirling around you like a hurricane, stop and be reassured there is a few things out there that still can make your life a little easier. It doesn’t make the killer bees go away but maybe it will give you peace of mind that your storage doesn’t run out in the near future.

My friend and colleague Ian Wright has put together an awesome You Tube video of the V7000 with the Flash Copy manager software. Ian has made several videos of the V7000 including a tour of the GUI, how to do things and now this. Ian says in an email to me earlier: "The video starts out with a restore of an accidentally deleted email (but not a restore of the spam that was deleted) and goes on to show recovering an accidentally deleted database. Both are actions that I think should resonate with customers using these applications."
I thought this was an awesome example of the V7000 and the Rapid Application Storage Solution that was release a few months back. Please take a few minutes to go through the video and give Ian some feedback.

My father is a retired teacher but loves to work with his hands. I can remember very early on in my up bringing, him teaching me that it is good to measure twice and cut once. Whether it was building a deck or just a bird house the point was it took more time to cut something wrong and then has to re-cut the board shorter or even wastes the old board and cut a whole new one.
When I was preparing for this article I remember having to learn that lesson the hard way and how much effort really is put into that second cut. The problem in the storage industry is the misaligned partitions from a move of a 512 byte sector to a new 4096 byte sector. This has to be one of the bigger performance issues with virtualized systems and new storage.
Disk drives in the past had a limit on the number of sectors to 512 bytes. This was ok when you had a 315 MB drive because the number of 512 byte blocks was not nearly as large as what is in a 3 TB drive of today’s’ systems. Newer versions of Windows and Linux will transfer the 4096 data block that match the native hard disk drive sector size. But during migrations even new systems can have an issue.
There is also something called 512 byte sector emulation which is where a 4k sector on the hard disk is remapped to 8 512 byte sectors. Each read and write would be done in eight 512 byte sectors.
When the older OS is created or migrated, it may or may not align the first block in the eight block group with the beginning of the 4k sector. This causes misalignment of a one block segment. As the reads and writes are laid down on the disks the misalignment of the logical sectors from the physical sectors mean the 8 512 byte blocks now occupy 2 4k sectors.
This now forces the disk to perform an additional read and/or write to two physical 4k sectors. It has been documented that sector misalignment can cause a reduction in write performance of at least 30% for a 7200 RPM hard drive.
This issue is only magnified when adding other file systems on top of this misalignment. When using a hyper visor like VMWare or Hyper-V, the virtual image can be misaligned and cause even further performance degradation.
There are hundreds of articles and blogs written on how to check for you disk alignment. A simple Google search of the words “disk sector alignment” and you will find this has been a very popular topic. Different applications will have different ways of checking and possibly realigning the sectors.
One application that can help you identify and fix these is a tool called the Pargon Alignment tool. This tool is easy to use and will automatically determine if a drive’s partitions are misaligned. If there is misalignment the utility then properly realigns the existing partitions including boot partitions to the 4k sector boundaries.
I came across this tool when looking for something to help N series customers who have misalignment issues in virtual systems. One of the biggest things I saw as an advantage was this tool can align partitions while the OS is running and does not require the snapshots to be removed. It also can align multiple VMDKs within a single virtual machine.
For more information on this tool and alignment check out the Paragon Software Group website.
In the end, your alignment will effect how much disk space you have, how much you can dedupe and the overall performance of your storage system. It pays to check this before you start having issues and if you are already seeing problems I hope this can help.
In answer to your requests for IBM N series demos, Andrew Grimes will be delivering a demo on Thursday, March 11th. This Introduction to IBM N series will be followed by a brief and informative demonstration of how N series delivers storage efficiency with disaster recovery solutions.

4. Most importantly, see how we recover these applications in a matter of minutes!
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.
Just a quick note on two new Solution Briefs that were posted to the IBM SONAS front page. These briefs have important information on using Symantec's EndPoint and NetBackup to protect data on the SONAS system. As always, the devil is in the details but this gives SONAS clients a look into how we can utilize these two solutions with the very powerful SONAS system.

I am also headed up to the IBM Storage University to present on NAS technology at IBM. If you get a chance to stop by and see one of my sessions, please come up and give me feedback on the blog (and other things). I will also be in the Solution Center at the SONAS booth.

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.

In response to: IBM Announcements May 2014 - Storwize FamilyTony, great job, also the V7kU 1.5 code now offers mult-tenancy now. FYI
In response to: Looking for FREE IBM Deep Dive information?These sessions are really good, I have been really impressed with the ATS guys and their depth of knowledge on these systems.
In response to: LTFS – Linear Tape File SystemKeith, good info on LTFS, I am always asking people how we help customers with deciding between LTFS and something like HSM via TSM. Also I didn't know LTFS is FREE. thats pretty darn cheap!
I keep hearing how great our compression appliance really is and how quick and easy it is to setup. I did some asking around the office and was sent this video. It does look simple and I wish other products had this type of instructional video. If you want more information about RTC, check out the IBM RTC site here. Enjoy the video and if you like this and have a suggestion for another one let me know!
IBM has been working to enhance the way we do business from day one. From clock, to typewriters, mainframes, PCs, software, storage... the idea behind our innovation is to make it easier for our clients to do their business. Now we are taking it one step further to help our clients make the world better.
If you have been watching standard TV, Youtube or Hulu, you probably have seen a commercial for the IBM Smarter Planet initiative. These great adverts keep the tradition of IBM marketing our message to the masses. They describe how IBM is making our world better by using technology through many disciplines; Healthcare, Traffic, Food, etc. If you dig a little deeper than the catchy ads, you see a real movement not only to 'save the planet' but to make our lives better.
One of the ways IBM is making our planet better is by increasing the utilization of our systems. Today's average commodity server rarely uses more than 6% of its available capacity. This hold true for our storage systems as well. We find storage systems are bound by traditional technologies that keep us from keeping up with demand.
Looking at how this relates to my involvement I see how both SONAS and N series fit this mantra. The technologies allow clients to conserve energy by decreasing the amount of storage needed to achieve typical installations.
N series software allows a client to over subscribe a system by cloning the volumes with out adding additional space. This software called FlexClone allows clients to use products like VMWare, Xen or Hyper-V to create zero space copies of the original image. This zero consumption keeps the original blocks locked to the original image and any new changes are added to the free space as a delta. In traditional storage systems, a 10GB image would consume 1 TB for just 100VMs. With FlexClone, the only space needed for all 101 VMs would be just 10GB. Lowering both the OPEX and CAPEX for this system.
The IBM Scale out NAS system (SONAS) is a gaining steam as the private cloud business has increased in the business market. Not only are research universities and high performance computing labs seeing the benefits, so are mid-market to enterprise business leaders. Typical storage systems are not utilized to their full potential because of the purpose of the system or how it was integrated into their data center.
With a SONAS system, we no longer have to think how this system will be provision as all of the equipment can respond to requests from multiple parts of the business. If you have 5 systems that provide storage to your business and one of those systems is struggling to keep up with demand, the only way to keep up with the requests is to move data off by hand to the other systems. This is time consuming and could introduce mistakes and possible data loss. SONAS allows clients to be flexible in a dynamic-on-demand business environment. No longer will you have one system slowing down productivity as all of the storage in a SONAS system can be distributed through out the entire client interface. This will increase your efficiency rates and lower the required amount of systems in your data center, lowering environmental cost, CAP/OPEX.
There are other Storage systems that can increase utilization, Information Archive moves older data off to low cost, slower disk allowing you to store more on primary, faster disks. XiV keeps data spread throughout the entire system in case of a failure with no traditional RAID overhead. We at IBM are constantly looking for ways to increase the utilization of our systems.
IBM is working hard to build a smarter planet that not helps our clients, but helps the human race. Either through smarter storage systems, servers, software or consulting, IBM is working hard to bring this vision to a realization. Take a look at your systems and take stock of their utilization. Can they be doing more for you? Find out more about the IBM Smarter Planet initiative here.
This week, I am at SNW in San Jose, CA. If you have never heard of the conference, its all about storage and networking and pulls in all of the big vendors to put on labs, lectures and a vendor hall. People come from all over the world to this event to learn what is new and how to do things better.
One thing that I love doing at these events is talking to customers and potential customers about IBM storage technology solutions. Often we find the conversations do not talk about products as much as the technology in them that fix some sort of issue in the data center. I think this is best seen when you come in to the IBM booth. There is no hardware to see blinking lights or yank cables. We have something better, people who know the solutions to your issues.
If you ask any of the IBMers that work these events, they always say it’s a love hate relationship. The hours are long and you stand on feet for 4-8 hrs. The best part is talking about IBM solutions and finding out what people are doing in the field. This is the best way to help drive innovation, listening to the customer. IBM has programs that send our developers into the field to listen to customers and this is just one example of that program.
Another event at SNW this year was a gathering of the storage social media moguls. This is a non-vendor specific event and is open to everyone. It is associated with a certain hash tag of #storagebeers and they have been going on all over the world. Last night was the largest storagebeers to date and it was a whos who of this community. But what was better than meeting the people that you see on twitter or those who write blogs, was the idea of putting all of the vendor fighting behind us and just a group of people who work in the storage industry talking about whatever was on their mind. If you find yourself at an event like SNW or VMWorld, check to see if there is a #storagebeers and go back and meet some really cool people.
If you are at SNW and want to come by for a chat, you will find me at the IBM Booth today between 11am and 3pm. I would love to spend some time learning about what you are doing in the data center.

I just read the blogs from Chris Mellor from the Register and Tom Trainer Network Computing and thought how insightful are these two outsiders about the inner workings of IBM.
First off, yes IBM is no longer selling the DCS9900, a DDN OEM rebranded system in the very large IBM storage portfolio. There is no question that this product is no longer available after the October 15 date.
Second, the DCS 3700 is already part of our portfolio and is now an OEM box from Netapp/Engenio/LSI. The density of this system is the same as the DCS 9900 and makes sense to use the DCS 3700 as a replacement for the DCS9900.
Third, Tom’s blog about SONAS being a monolithic NAS storage is very skewed. SONAS is a very flexible in the way we can scale both storage and the throughput with out affecting either variable. Most “scale out” systems you have to scale both in order to keep up with demand. SONAS uses some of the best technology on the market with a huge amount of throughput.
His statement about IBM dropping DDN from SONAS is un-true and goes to show how much research Tom put into writing this blog. I am sure Tom is looking out to write a non-biased blog for Network Computing but maybe those days at HDS are still making a big influence in his ability to look at announcement letter and make a extrapolations about other products.
Finally, If HDS thought BlueArc was so great, why didn’t they buy them back when they could have gotten the company for a better deal? Has the product changed THAT much since 2006? I wish HDS only the best for dealing with the transition and getting that product under the HDS umbrella.
If you do your homework and base your assumptions on facts instead of conjecture, you will find SONAS is a solid platform in the enterprise NAS market. SONAS has proven it can be the market leader with a low cost to performance ratio and will only get better as time goes on.
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 working with a company today that had 5 storage vendors supplying gear for their data center. They were interested in SONAS not only for the scalability but for the idea that we could consolidate their storage footprint from 5 vendors to 1 with out having to sacrifise performance. Now must vendors would say, sure we can rip and replace all of the storage there and replace it with their own, but can they do it to the same scale (both horizontal and vertical), with a high performance engine like GPFS, one global names space and one single management tool? The customer was really impressed by our solution as is very interested in how we can help him go from 40+ racks of storage down to 13 and increase his efficiency.
The idea is to use multiple teirs to put meta data on the faster disk, data that is being accessed currently on a medium speed and then 'near to archive on slow, fat disk. Currently they have no way of moving data between their 5 different systems. This causes them to keep running into issues where they are buying expensive disk to run applications/databases where they have data that is stagnant or non as important on the existing fast disks. SONAS will allow them to create pools of storage (tiers) and policies to move the data between the pools. Then with the HSM integration, the data can be archived off to tape until needed down the road.
From a cost perceptive, the cost associated with the size and speed of the disk match their purpose with out them having to manually move the data themselves. With IT departments that have a huge growth in storage and are not hiring more admins, this makes sense. They can set the policies up front and not have to worry about some old file sitting on a expensive SAS disk. The other expense savings is in support contracts. The reduction from five support contracts to one will save customers money, and allows them to have one place to get all of their support.
I can not wait to start work on this account as it looks like we will be putting in a great system and helping a client save money.
There are few times that I look at what a company markets as the 'Next big thing' in the storage world and get the same reaction I got when I started learning about the SONAS product. There is already some technical details in the announcement and in Tony's blog from a few days ago so I wont go into that today, but I will go over how this product really makes a paradigm shift in the NAS storage world.
Traditionally NAS storage is looked as the little brother to the bigger systems of SAN. SAN systems tend to be the athletes of the storage high school with their matching letter jackets and oversized girth. All the while, NAS was the band geeks, some frail and thin and some over sized but always in large numbers and not very organized. NAS technology was born from the need to share data over he company and as the amount of information grew so did the servers, network bandwidth and backups. SAN storage is still the big guy on campus but the people that track trends for our industry say NAS has become just as important as the large databases, ERP systems and the like.
If you look at how we have stored NAS data, it has been on single file systems that had local disk drives shared out over a single 10/100 mb network. As storage systems became more advanced, we saw people using clustering, snapshots, thin provision, de-duplication and replication to help keep our companies communicating. When we needed more throughput or more storage we added a server or added disks which created islands of unshared power.
If you look at 2009 and one of the hottest buzz words in the storage market, it was cloud computing. Having a large source of power in one area to pull resources from without having to provision new equipment. We also saw more and more clients looking at NAS protocols as the Ethernet could support faster speeds than traditional fibre channel. A huge amount of you have been looking at and moving your virtual environments to NFS to help cut down on administration overhead and to take advantage of the CNA technology.
With a higher demand for NAS technology, comes the burden of being able to scale at the same rate the storage, network and throughput increases. Older NAS systems allowed clients to increase the amount of storage but once you reach the critical mass the system allowed you had to purchase another clustered system. This creates multiple islands of storage pools that have be managed, provisioned and backed up. Not a great solution for companies that are growing and have fewer administrators to do the work.
Now, IBM has a product that allows our NAS clients to grow and scale as their companies grow. SONAS is a highly scable NAS that works like a cloud. The underlying technology, GPFS, is the same found in some of the fastest computers in the world. SONAS uses a method of scaling in both storage and throughput by adding storage pods (60 SATA or SAS disks) or interface modules (x3650 servers) like Lego blocks. All of this is managed by a central command module that allows a client to have full control over the entire system no matter how much storage or servers are in the system.
So the "Next big thing" in my opinion is here today and IBM is using the best of the best of IBM research for it's clients. The SONAS solution is designed from the ground up as a true blue NAS storage solution. Look for future SONAS blogs on GPFS, creating an ILM strategy and more.
