Transcript of "Tier X - Stretching Tiered Storage from SSD to Cloud"

  1. 1. Tier X - Stretching Tiered Storage from SSD to Cloud Storage Expo London Kirby Wadsworth Vice President – Global Marketing
  2. 2. 2 Outline • Tiered storage basics • Introduction to file virtualization • Storage technologies continue to evolve • Optimizing for lower cost • Optimizing for application performance • Reduce costs and increase flexibility with cloud • Bringing it all together • Summary
  3. 3. 3 Tiered Storage Basics
  4. 4. 4 What Is Tiered Storage? • Not all data is created equal • Dynamically match type of data with a storage system optimized for that data type • A simple way to start: – Segregate data into active and inactive data sets • Active data placed on high-performance storage • Inactive data placed on low-cost storage • Dramatic cost benefits
  5. 5. 5 History of Tiered Storage • Historical impediments – For many years, the opportunity to tier was limited by the absence of a good choice for the second tier • Tape too slow and fragile for general purpose Tier 2 – Adding a tier of storage was not transparent to user and application access to data • Moving data is disruptive • What changed? – Introduction of high-capacity SATA • Acceptably slower when used to store less active data – File virtualization
  6. 6. 6 Introduction to File Virtualization
  7. 7. 7 What Is File Virtualization? Before After Applications and Users Applications and Users Logical Access File Virtualization with “Decoupling” Integrated Services Physical Access Servers Servers • Logical abstraction of file systems • Decouples access to files from physical location of files

  11. 11. 11 Storage Technologies Continue to Evolve
  12. 12. 12 Traditional Storage Technologies Higher Performance Traditional Tier-1 (High-perf SAS) Lower Traditional Higher Cost/GB Tier-2 Cost/GB (High-cap SATA) Lower Performance
  13. 13. 13 Emerging Storage Technologies Higher Performance Memory Lowest $ Storage per IO/sec (SSD) Traditional Tier-1 (High-perf SAS) Lower Traditional Higher Cost/GB Tier-2 Cost/GB (High-cap SATA) Optimized Lowest $ per GB Storage (Dedupe SATA) “Elastic” Storage (Cloud) Lower Performance
  14. 14. 14 Integrate Heterogeneous Storage Technologies Applications and Users File Virtualization Real-time matching of application/business needs and storage capability Memory Traditional Traditional Optimized “Elastic” Storage Tier 1 Tier 2 Storage Storage (SSD) (High-perf SAS) (High-cap SATA) (Dedupe SATA) (Cloud)
  15. 15. 15 Starting to Tier: Optimize for Lower Costs
  16. 16. 16 Why Companies Started to Tier Storage IT Budget Constraints Volume of Data Growing Total Enterprise Disk Storage Systems Shipped IDC: Worldwide Network Controller and Block-Level Storage Virtualization 2008– 2012 Forecast: A Key Component in Building the Virtual Datacenter, April 2008 IT is seeking cost and efficiency improvements IT is seeking cost and efficiency improvements
  17. 17. 17 Simple Model for Active Data Management u:PresentationsBoD.ppt Virtual Namespace File Virtualization Physical Namespace Not modified in last month 10% 90% Tier 1 Tier 2 Same Weekly Fulls (x5) But only 10% of the data Modified in last month No Weekly Fulls Backup (only Monthly+)
  18. 18. 18 Case Study – Medium Enterprise • Challenge – rapid data growth: – High costs for disk capacity – Long backup times and high costs for backup media • Solution – Moved data not modified in last month (90%) to Tier 2 – Different backup policies for Tier 1 and Tier 2 • Benefits – Disk cost savings • New disk capacity is all Tier 2 (at 1/5 the cost…) – Backup cost savings • Weekly full backups consume 10% tape media • Weekly full backup times dropped from >36 hours to <3 hours
  19. 19. 19 Sample Cost Savings – 25TB Environment • Hard cost savings – Use of lower-cost disk storage $270,000 – Reduction in backup costs $50,000 – Increased capacity utilization (40->80%) $536,000 – Power savings $34,000 – Total $890,000 • Soft cost savings – Transparent cross-vendor/technology capacity expansion – Transparent cross-vendor/technology migration – Reduction in backup/restore times – Reduced backup failures
  20. 20. 20 Cost Comparison – $/GB Tier-1 $42/GB $45.00 Delta $1.53 $36/GB $40.00 $2.50 $1.36 $35.00 $2.00 $30.00 $22.81 Power $25.00 Backup $21.75 Util $20.00 Disk $15.00 Tier-1+2 $6/GB $10.00 $15.21 $0.50 $0.16 $1.06 $10.95 $5.00 $4.26 $0.00 Tier‐1 Tier‐1+2 Delta

  23. 23. 23 Case Study – Technology Company • Challenge – Migrated software developers from physical to virtual servers – User response time became unacceptable when multiple software builds were running parallel against the shared VM storage • Solution – Moved data from disk to “low-end” SSD • Benefits – Worst-case response times dropped 50x – Increased developer productivity

  29. 29. 29 Case Study – Health Care Provider • Existing file virtualization customer – Large NAS environment with two tiers today • Tier 1 is traditional high-performance NAS • Tier 2 is deduped NAS • Starting a pilot with cloud as Tier 3 – Use cloud as “spillover” capacity – Accesses cloud though a file system gateway • Benefits – Maximizes utilization of Tier 1 and Tier 2 (= lowest cost…) – Supports dynamic capacity increases and decreases • No hardware provisioning needed

  33. 33. 33 Summary • Storage tiering optimizes storage resources for performance and cost based on business value – There are many storage choices available – File virtualization enables you to easily utilize heterogeneous storage resources or technologies • How do you start? – Deploy Tier 2 today to reduce costs and improve backup – Consider deploying SSD to address application performance challenges – Start planning for cloud • Deploy today for increased flexibility in managing storage • Ramp up deployment as prices continue to decrease
