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.

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.
Here is a You Tube video of Windows Explorer VSS and IBM SoNAS snapshot demonstration by Roshan Ratnayak..
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.
