2 Storage Session Lecture Presentation Session Title: Exploiting Tier 0 and Storage Virtualization to Maximize Storage Performance Abstract: Tier 0 is a level of storage that s faster though perhaps more expensive than any other level in the storage hierarchy. But how do you justify its costs? By combining technologies such as Flash (TMS) and solid-state drives (SSD) with Storage Virtualization (SVC and V7000), and then applying application awareness or smarter data placement, companies can realize significant cost-saving benefits. This presentation will illustrate how using these performance accelerators with Storage Virtualization can eliminate the current Disk I/O choke points in your servers or applications. What Attendees Will Learn: Attendees will see how applications such as VDI, highly transactional databases and Private and Public Storage clouds can leverage these high-level technologies to increase performance, productivity, and ROI. Live examples and supporting charts will quantify the critical need to exploit these storage technologies. 2

3 What is TIER 0 Tier 0 is a level of storage that s faster, and perhaps more expensive, than any other level in the storage hierarchy. 3

4 Flash vs SSD Flash is hardware based arrays providing maximum performance and lowest latency with optimized Field-programmable gate array (FPGA) hardware only data path SSD is composed of flash that is put inside a carrier and inserted into an array like a hard disk drive, there is added latency caused by controllers, software layers, and shared data paths. What Should I use? Use SSDs to optimize performance when there are less than 6 SSDs. When there are more than 5 SSDs, Flash System is a more cost and performance effective choice. Do your own Pricing Exercise SSD s will generally be microseconds additional latency. Does that matter? 4

5 Benefits of TIER 0 with Storage Virtualization 5

6 Benefits of TIER 0 with Storage Virtualization Applications see time waiting, not IOPS All client requests take time I/O Time Network Time CPU Time Newer CPUs help I/O Time Network Time CPU Time Newer CPUs + RamSan or SSD magnify the gains I/O Time Network Time CPU Time Time Recovered 6

7 Benefits of TIER 0 with Storage Virtualization Dramatically boosting the performance for workloads that really need it. Significantly improving response time for better and timely decision making Add Business value by reducing overall processing time Easy to move around expensive assets (SSD-Flash) to maximize customers assets and provide a better ROI. **HUGE** 7

Expected to save $3+M in first 2yrs 12

13 Storage Benchmarks Notes: A Single V7000 will be able to Drive GB SSD drives to 120K IOPs 120K IOPs is a LARGE workload 13

14 Private Storage Cloud Real World Notes: Customer #3 generates a total of 45K IOPs on SVC3 14

17 Database volume read acceleration in Tier0 V7000 Database Vdisks Using EazyTier and SSD, able to accelerate database volumes to.3 -.6ms read service times Supply just enough SSD into Storage pool to increase Database volumes performance for a critical application demand 17

18 VDI volume read acceleration in Tier0 SVC VDI Vdisks Using EazyTier and SSD, able to accelerate VDI Storage Pool from 4.2ms to 1.2ms read service times. Storage Pool contains SAS 10K drives (Red/Yellow Lines) Using EazyTier and SSD, able to accelerate VDI Storage Pool from 10-12ms to 4-6ms read service times. Storage Pool contains SAS 3TB drives (Green Lines) Supply just enough SSD into Storage pool to increase VDI volumes performance for a critical application demand 18

19 VDI volume read acceleration in Tier0 SVC VDI Vdisks Using Performance management tools, such as Galileo, we are able to view the hottest IOP vdisks and corresponding service times to measure the benefits of TIER 0 These tools allow us to properly identify the best candidates for movement to TIER 0, and allow us to identify the best placement of TIER 0 assets and movement between SVC Storage Pools for maximum benefit 19

20 TMS vs Violin Here are the initial results of our TMS vs. Violin test. We ran 5 servers split 2 on the first ESX host and 3 on the second. The IOmeter settings are:» 2 Workers Each w/ 100GB LUN» 4k (60% Read) Workload 100% Random» 32k (40% Write) Workload 20% Random» 10 Outstanding I/O s Per Worker The test was first run with TMS volumes from SVC in Cache bypass mode. Then we migrated the volumes in real time over to the Violin. That explains the dip in performance during that time. After the migration completed things level back out. The graphs should explain it all, dramatic decrease in performance after the move to Violin. 20
