H1. 6, not Q2.    Also see comment section for deduplication dialogThis is, in my personal opinion, one of the coolest stories at EMC World this year and let me tell you why. What do you think is harder inventing something new with a clean sheet of paper, or changing the entire car as its barreling around a racetrackTheres a joke in the IT industry that The reason God was able to create the world in only six days was because he didnt have to deal with an installed base. I think what Unity represents is an incredible engineering achievement and an incredible story a wholesale architectural change, while moving, with a massive installed base. This post will cover whats new in Unity, but the thing that the most fascinating is the story behind the story. Unity Scripts. unitypackageUnity Scripts AssetsIve been lucky to see it from the inside, and today Ill share it from my perspective with all of you. EMC VNX has an installed base that is well, well north of 1. Aretha Franklin Respect The Very Best Of Download Google on this page. It has been the most successful EMC platform to date in terms of the number of people and customers, and VNX brings more net new customers to EMC than anything else we do even as it became increasingly aged. The VNX was released on Jan 1. Thats more than 5 years ago. For perspective, thats when the first Mac. Book Pro was released, and about a year before Windows Server 2. Since then its been a huge success. Now even before the VNX was born, we were already grappling with how we would transition the architecture and move completely past its CLARii. ON and Celerra roots, and their deep architectural underpinnings we needed to move away from the old, but how There are other examples of change the engine while the car is running in the storage ecosystem playing out, and it is NOT EASY. Im not saying were perfect, but this is an interesting example that has been occurring in parallel, somewhat under peoples noses. Unity is that and its a whole new platform we have swapped every part out while not missing a beat in VNXVNXe. Unity will redefine the mid range unified market. Its faster, denser, less expensive, and simpler than all of its competition and were willing to put our money where our mouth is with a money back guarantee. VNX was the king in this space. The King VNX is dead though not EOL, long live the King Unity For more gory technical detail, and the fascinating story behind the scenes read onAs Ive noted before it takes a lot of time to harden a storage stack from inception. A rough rule of thumb is 5 years for a transactional stack, 7 years for a NASObject stack. Scale Outdistributed variations are materially harder. This isnt a matter of smarter engineers its rather that persistence stacks are HARD, and I hate to say it, but theres an incompressibility of the schedule because in part that time is because they get hardened at customers, in deployments, over time. When youre a big company vs. For example, as Isilon and Xtrem. IO have ramped like crazy they both have gone through bumpy periods before they stabilized. How do we do it for the most widely deployed enterprise storage stack VNX on the planet while minimizing customer and business risk As a business, we embarked on an long journey with important milestones that culminate today. I want take a moment to give a shout out to Rich Napolitano under whose watch this started, and the hundreds of engineers who have invested blood, sweat and tears over the years what a journey its been. This has been a journey to redefine, recreate the world best mid range external scale up unified storage platform, and do it without risking customers, partners, and revenue. You can literally see powerpoints of the internal strategy in the bottom of this post from 2. The journey can be summarized this way and its fascinating to any people interested in this part of the industry you have to play the long game Step 1 build a new core platform at the kernel level that would allow us to modularize the code, and support containerized packages, as well as clean kernel mode insertion of things that need to be very close to the hardware. This project was codenamed C4. Step 2 find a way to test that out and start hardening with customers. Thus was born the VNXe in 2. You can see this milestone in the journey here. The VNXe has turned out to be a huge success bringing more new customers to EMC than anything weve built before. There are still things smaller than a VNXe, and Unity, but thats another story for another day. Step 3 At the same time that you do Step 2, completely do a ground up re write of the block stack. Start changing the design center in anticipation of pervasive flash, and multi core CPUs this was jettisoning the old FLARE code base that VNX inherited from CLARii. ON, and replacing it with MCx. Without these changes, legacy very simple mapping models would inhibit new data services like compressiondedupe, and would leave the platform in the 1. LUN ownershipfailover behavior. This was born the VNX2 in 2. Like VNXe, the VNX2 has been a wild success billions of dollars of revenue, hundreds of thousands of customers. Step 4 completely re write the NAS stack, which was mature in both good and bad ways. Good very robust, and with all the stuff enterprises expect. Bad 3. 2 bit filesystem seriously that meant small filesystems and filesystem limits, a legacy mechanism for filesystem meta data mapping that meant that NASblock functions were very disparate, and failover behavior was too slow. What was needed was a modern 6. NAS re write that mapped into the new block mapping code. Each of these steps were carefully coordinated, and consciously broken into digestible parts so that each part would get hardened, tested and we would ultimately change the whole car while barreling down the highway. That journey ends today and a new journey with the new platform, Unity, begins. Unity will cover the entire market segment that VNX and VNXe currently serve. Well not entirely. Weve realized that at the top part of the VNX bands VNX8. Xtrem. IO and VMAX All Flash rule the market expect them to have configurations that move down to cover the top part of that market. Unity is squarely focused at the external storage use cases that start small into the lt 1. K bands, and with all flash configurations that start at 1. K and go up to 5. SSDsHDDs. How small is start small Well with Unity we are covering the VNX market as a whole with the system architecture that looks like a VNXe. U, and everything is in there. How powerful In practice, about 3x more performance than the previous generation at every scale point, and not just more powerful, but more dense, more simplicity, less power consumed not a small leap, but a huge leap. Wow. And the core codebase isnt just faster, its also better. New mapping, snapshot underpinnings, and a killer advancement in the Qo. Psa Xs Evolution Driver. S behaviors where there much finer granularity, and the ability to provide distinct Qo. S handling for primary devices versus replicas. Now if you look at the picture youll notice there are NO datamovers or file blades. The convergence is complete. Speaking of the filesystem Ill say this strongly this aint your daddys VNX.
