10 Flash Cache (PAM II) New Way to Optimize Performance Functions as an intelligent read cache for data and metadata Automatically put your active data where access can be fast Get more I/O throughput without adding high-performance disk drives to a disk-bound storage system Effective for file services, OLTP databases, messaging, and virtual infrastructure Predict your results before buying for an existing storage system 10

11 Reduce Latency with Flash Cache (PAM II) 11

12 Configurations with Flash Cache (PAM II) More Ways to Achieve Your Goals for Performance and Cost + Flash Cache + Flash Cache Configure with FC or SAS Disks Only Additional disk drives provide IOPs Inefficient use of storage capacity, power, and space Configure with FC or SAS Disks and Flash Cache Disks provide capacity/iops Flash Cache can provide IOPs and reduce latency Achieve cost savings for storage, power, and space Configure with SATA Disks and Flash Cache More storage capacity Flash Cache can provide an IOPs boost for SATA drives Achieve cost savings for storage, power, and space Note: Flash Cache (PAM II) is most effective for read-intensive, random I/O workloads 12

13 Predict Your Flash Cache Results Predictive Cache Statistics (PCS) Feature of Data ONTAP 7.3 and later releases PCS simulates the effect of adding Flash Cache (PAM II) to the storage system under the current workload Lets you determine whether Flash Cache will help and how much to use 13

14 Flash Cache Lets You to Scale Performance of Disk-bound Systems without Adding Disk Drives + Flash Cache Add Spindles Use more disks to provide more IOPs May waste storage capacity Consumes more power and space Starting Point: Need More IOPs Performance is disk-bound Have enough storage capacity Random read intensive workload Add Flash Cache Use Flash Cache (PAM II) to provide more IOPs Improves response times Uses storage efficiently Achieves cost savings for storage, power, and space 14

15 Workloads Fit for Flash Cache (PAM II) Best for Small Block, Random Read Workloads File services OLTP databases VMware, Citrix, and Hyper-V Microsoft Exchange and SharePoint Engineering and SW development Workloads that Might Not Benefit as Much... Write intensive workloads Workloads running on storage system where CPU is the performance bottleneck 15

16 Photobucket Uses SATA to Reduces Costs, PAM I Caches to Maintain Performance Photobucket is the premier site on the Internet for uploading, sharing, linking, and finding photos, videos, and graphics. The company was founded in 2003 and acquired by Fox Interactive Media, Inc., a division of News Corp., in July The company is head-quartered in Denver, Colorado with offices in San Francisco, California. Most popular photo site in the United States 46 million unique site visitors/month worldwide Over 7 billion images Challenge Storage is one of their largest expenses Goal: Reduce cost but not performance Running out of data center space Immense number of small files Finding the files is much of the work Solution 8:1 reduction of storage controllers Use SATA disks instead of FC disks Maintain performance by caching metadata in storage controller Instead of four top-end controllers, use a pair of lesser controllers with three PAM I caching modules installed in each Benefit Saved 17% or $410k (US List) by using PAM I caching modules Reduced data center footprint from 16 to 4 rack cabinets 16

17 Flash Cache (PAM II) 2 nd Generation Intelligent Caching Modules Product Details Fits into PCI Express expansion slots like the original PAM card Enterprise class SLC NAND flash memory Available in 256GB and 512GB sizes Up to 4TB cache per storage system 17

18 Relative Sizes of Caches and Data Flash Cache Holds More Active Data Our 2nd generation intelligent caching modules are big enough to hold metadata and large amounts of active data. PAM I 16GB Metadata 1 Flash Cache 256GB Flash Cache Active Data GB Entire Dataset

19 Cache Size and I/O Throughput Flash Cache (PAM II) can improve I/O throughput by caching more active data Throughput (IOPs) Metadata Active Data PAM I Cache Size Flash Cache 19

20 Operations per Second Performance Improvement Example Spindle Limited OLTP Workload Throughput Gain Due to Flash Cache Flash Cache (PAM II) is More Effective than Adding Disk Drives k k k k % Baseline system was FAS3160 with 84 high-performance disks Tested under OLTP workload Adding 1TB of Flash Cache increased I/O throughput by 78% Average response time improved by 30% with Flash Cache 10k more disks needed to get same throughput as 1TB cache BASELINE Configuration Plus 1TB Flash Cache 1TB Flash Cache costs 55% less than adding 140 more disks 20

21 Response Time (ms) Flash Cache (PAM II) Storage Efficiency Example Get Your Data Even Faster, Reduce CapEx and OpEx Benchmarked FAS3160A Configs SPECsfs2008 Performance 224 FC disks FC Baseline FC + Flash Cache 64TB 75% Fewer Spindles WORSE FC drives 16TB BETTER 2 1 FC Baseline Configuration FC + Flash Cache Configuration Throughput (k-ops/sec) Purchase price is 49% lower for FC + Flash Cache compared to FC baseline FC + Flash Cache provides 67% power savings and 67% space savings For more information, visit SPEC and SPECsfs2008 are trademarks of the Standard Performance Evaluation Corp. 21

22 Response Time (ms) Flash Cache (PAM II) Improves Storage Efficiency Use Fewer Disk Drives, Get More Capacity, Maintain Performance Benchmarked FAS3160A Configs SPECsfs2008 Performance 224 FC disks FC Baseline SATA + Flash Cache 64TB 50% More Capacity 4 3 ILM? 96 SATA disks 96TB WORSE 2 BETTER 1 FC Baseline Configuration SATA + Flash Cache Configuration Throughput (k-ops/sec) 0 Purchase price is 35% lower for SATA + Flash Cache compared to FC baseline SATA + Flash Cache provides 66% power savings and 59% space savings For more information, visit SPEC and SPECsfs2008 are trademarks of the Standard Performance Evaluation Corp. 22

23 Interoperability Flash Cache (PAM II) Cards are Team Players They work with every storage protocol All storage behind the controller is subject to caching You can set Quality of Service priorities for PAM caches with FlexShare Deduplication applies to PAM caches PAM family cards can be used with V-Series Open Storage Controllers 23

24 Summary Flash Cache (PAM II) Intelligent Caching Key Points Automatically put your active data where access can be fast Get more I/O throughput without adding high-performance disk drives Effective for file services, OLTP databases, messaging, and virtual infrastructure Predict your results before buying for an existing storage system Realize CapEx and OpEx savings DEMO 24
