This session examines how next-generation file storage architectures will see a convergence of server and storage
virtualisation in a way that will use technologies available today to integrate primary storage, file archive, and the cloud.

  • Data is growing really really fast. This isn’t a surprise to most of you.But just to put it in perspective, IDC says that the total amount of data in existence – the digital universe – is going to grow 44 times between 2009 to 2020.[CLICK] What does that mean exactly? What does 44x growth look like?Now obviously, you don’t have to manage 35.2ZB of data - your environment is a microcosm of this growth.
  • That’s great, but what does that mean to you?Data growth causes a number of problems.
  • So you need to do something about this growth problem…but what?The storage industry is great at coming up with new technologies to try to address your needs, and cloud storage is just the latest technologyBut as you can see, you’re really faced with a bewildering array of storage options
  • Leonardo da Vinci said that simplicity is the ultimate sophisticationSo let’s try to simplify the picture somewhatIf you try to map all of the available storage options, you can create a simple picture that delineate differences in performance and cost.[CLICK] In the upper right-hand corner, you have high cost, but high performance[CLICK] In the lower left-hand corner, you have low performance, but low cost
  • So now we’re going to map your storage requirements to this idea[CLICK] Only a small percentage of your data needs to have the performance [CLICK] Most of your data is happy to be stored on lower-cost storage
  • So what does this really mean? We have to match your storage requirements to the available optionsBack in school, those of us who believed in efficiency lived by a valuable rule – 50% of the work will get you 80% of the benefit…Most organizations can get a lot of benefit out of a simple tiered infrastructure that boils everything you saw on the previous slide into a few simple bucketsStart with your “traditional” concepts of Tier 1 and Tier 2[CLICK] If you need more performance, add a memory-based “Tier 0” for the applications that need it[CLICK] Add cost-optimized storage for medium- to long-term archive of data that you want to keep in-house[CLICK] The cloud is a natural extension to this concept. Cloud storage can save you both capital and operational expenditures, with the delineation being really long-term archive of data that you’re comfortable outsourcing to third-party providerNow, keep in mind that what you implement is dictated by the needs of your organization. You may not need all or even most of these buckets.
  • What you do need is the ability to integrate them.The Galapagos Islands are an apt metaphor for how our storage environments tend to evolve over time[CLICK] As you may know, the Galapagos Islands are geographically isolated from other land massesThis means that it’s near impossible for animals to migrate between themLikewise, many storage environments contain what we call islands of storage, collections of storage resources that are isolated from each otherIt’s extremely difficult to migrate data or share capacity between them.This means it’s difficult to integrate them.
  • Why do traditional storage infrastructures make it difficult to integrate different types of storage?Each storage system is allocated for a specific purposeDifficult to move data between systemsEven if you could move data, constant growth makes it difficult to identify what data to move
  • So we have to get around this problem if we’re going to build a “cloud-ready” storage infrastructure.What does that really mean? What do you need to be “cloud-ready”?[CLICK]Let’s start from the top with users and applications. Now today, users and applications access data on a storage device located somewhere geographically nearby, such as in your data center.[CLICK] But you’re thinking about the cloud. How is that different? Well to start, it’s probably located somewhere other than where your clients are located – either in a different data center or in a third-party provider. So it’s geographically separate.[CLICK] So that calls into focus the first thing you need – a way to hide the fact that you have both local and cloud storage from clients, a way to make it seem like a single storage pool.[CLICK] Next, you need to enable data mobility to give you a way to move data from one part of the pool to another without disrupting access[CLICK] So now you can move data from one location to another without impacting clients. Now you need to figure out what data to move.[CLICK] And then you need to identify and move data automatically, because you don’t want to be doing that constantly.
  • Virtualization is the key to agility
  • Let’s take a closer look at what data mobility actually means.[CLICK] The user accesses his home directory through a virtual CIFS share presented by the ARX device instead of a physical CIFS share presented by a storage device. This user has saved three files to his home directory, a PPT, DOC, and PST file.[CLICK] Behind the ARX, the user’s files are actually stored on physical CIFS shares presented to the ARX by the NAS device and Windows file server. Here, the PST file physically resides on the NAS device, while the PPT and DOC files physically reside on the file server.[CLICK] Regardless of where each file physically reside, the ARX automatically proxies the user’s logical access to that file to the proper physical location on backend storage.[CLICK] Note that all of this is completely transparent to the user – all he sees is a single CIFS share through which he accesses his files.
  • The next step is to classify your data[CLICK] The basic premise is that not all data is created equal. You can see four types of data here[CLICK] These four files have varying degrees of business value, by type, age, name, etc.[CLICK] And, of course, the business value of these files will dictate on what types of storage you want to place them
  • So let’s put it all togetherEvery environment is different but this slide just shows one example of how you can create a simple tiered storage implementation with different storage types[CLICK]First thing you do is identify the types of files that need super-high-performance. Then, you can create a policy that places all of those files by default on this tier. [CLICK] For most applications and general user data, newly created files are placed on performance-optimized disk[CLICK] Newly created files that don’t have any business value are automatically placed on cost-optimized storage[CLICK] Files that have not been modified in the last three months are automatically moved to cost-optimized storage[CLICK] Files that have not been modified in the last year are automatically moved to the cloud

  • It really is a journey - you’re not going to get there todayBut you are going to get there and it will be easier if you prepare your infrastructure beforeAnd you know what they say, the journey is half the funThere are several stages in the journey – each stage can offer your organization significant benefits regardless of your final destination
