• #9: NexGen data reduction technologies deliver performance, endurance and capacity benefits for our All-fash arrays.
• #10: We believe that QoS will be a requirement for the next generation of all-flash arrays. NexGen¡¯s dynamic QoS simplifies performance management and delivers more consistent application performance. Rather than make admins manually input performance targets, we¡¯ve done the work, by creating five simple to assign policies. for them unlike other QoS offerings that force end users to react to a noisy neighbor and manually input minimums, maximums, and burst settings for every single volume in the system. ? NexGen¡¯s Dynamic Storage QoS has three distinct attributes. The first is that it allows customers to apply performance targets to Volumes and VMs. This manages min and max performance levels in terms of IOPS, TP and Latency. Predefined policies control everything, including how data is prioritized, including intelligent BW throttling and queuing to ensure service levels are met. Finally, since we¡¯re a multi-tier architecture, real-time data placement is paramount. This is where features like prioritized active cache ensures that flash is prioritized for more critical workloads. Emphasize dynamic QoS simplifies performance management and delivers more consistent application performance, unlike other QoS offerings that force end users to react to a noisy neighbor and manually input minimums, maximums, and burst settings for every single volume in the system. ? Often times customers don¡¯t realize how much performance to provision, NexGen¡¯s patented QoS uses massive amounts of performance data collected from production environments to pre-define 5 simple policies that automate performance management. ?This is especially important for customers considering using Vmware vSphere 6 with virtual volumes (VVOLs). ?VVOLs can increase the number of objects in a data storage system by 30 times, there is no way users can scale by manually inputing minimums and maximums on every single VVOL. ? PRIORITIES Another shortcoming of other QoS engines is the ability to over-provision system performance. ?Just like thin provisioning in the capacity world, the ability to over provision is key to maximum utilization of resources. ?QoS engines with manual minimum, maximum, and burst settings leave users stranded when it comes to over provisioning as without a way to prioritize between the various performance targets during the times where the system is encountering contention (due to over provisioining), the system can¡¯t make the right trade-offs and ensure mission critical apps get consistent performance. ? PLACEMENT There is a proliferation of new types of non-volatile media including several different types of flash. ?The only way to ensure customers achieve the most affordable all flash system while avoiding latency spikes and contention is to use multiple tiers of flash managed by a QoS engine. ?NexGen designed it¡¯s architected all management capabilities around the concept of QoS in anticipation of using the best of all worlds from multiple media types and types yet to be discovered. ? ? VVOL INTEGRATION Our policies are integrated with Vmware¡¯s Storage Based Policy engine (SPBM), that radically simplifies VM-level performance management. ?Changing performance is as simple as changing a selection on the drop down menu item ¨C end users notice the change in seconds.
• #11: Add VMs and Applications
• #12: Policy based QoS allows any one managing storage to easily assign priorities to a vm or volume. There are 5 preconfigured QoS policies. You¡¯re looking at the QoS policy for the NexGen n-1500 all flash array. One of the our two existing hybrid policies is shown below so you can see the difference between QoS for multi-tier w/ HDD vs. multi-tier all-flash. Keep in mind that each set of polices were designed. To align w/ the amount of flash in the system.
• #14: Why does QoS matter in practice? Because customer data is not homogeneious. They have different performance requirements and SLAs. Take for example VDI. ¡­.
• #15: For SQL customers, this allows customers to attain the granular performance mgmt. that exists with stand-alone instances. Policies can be assigned to VMFS, and now with VVLos support, wach instance gets granular performance management. Our policies are integrated with Vmware¡¯s Storage Based Policy engine (SPBM), that radically simplifies VM-level performance management. ?Changing performance is as simple as changing a selection on the drop down menu item ¨C end users notice the change in seconds.

• #27: 2015 4x 6-core Intel Xeon E5645 2.4GHz (2x CPU per storage processor), 24x physical cores / 48 cores with hyper-threading
• #28: We¡¯re very excited for the upcoming release of our multi-tier all-flash, and believe that QoS as a key element to enable the next generation of all flash arrays. Our data reduction technologies and Dynamic QoS play a vital role in ensuring our customers get efficient predicable storage results from their all-flash arrays.
