New Generation of Storage Tiering

  1. 1. New Generation of Storage Tiering:Less management, lower investment and increased performanceTony Pearson – IBM Master Inventor and Senior Managing ConsultantMarch 2013 © 2013 IBM Corporation
  2. 2. Today’s Challenges, Tomorrow’s Opportunities IMPROVE SERVICE Not only ensuring high availability and quality of existing services, but also meeting customer expectations for real-time, dynamic access to innovative new services. REDUCE COST Not just containing operational cost and complexity, but achieving breakthrough productivity gains Deliver the right through virtualization, optimization, energy stewardship, and flexible information, sourcing. to the right people, at the right time … MANAGE RISK Not only addressing today’s security, and compliance challenges, but also … with an IT infrastructure preparing for the new risks posed by in a dynamically changing an even more connected and collaborative world. environment2 © 2013 IBM Corporation
  3. 3. Four Fundamental Truths – A Basis for Storage Tiering 100 Machine data Email 80 EMR Database Data Value Surveillance Video 60 40 20 0 1w 2w 3w 4w 3m 6m 9m 1 yr 2 yr 5 yr 10 yr Age of Data All data is not created equal IT resources should be allocated according to the value of data Information changes in business value and in service level Information must be managed requirements over time throughout its entire lifespan … data outlives media3 © 2013 IBM Corporation
  4. 4. Storage Tiers – A trade-off between performance and cost Technologies allow us to Server place and move data to the appropriate storage tier to Faster balance betweenPerformance Cache and performance and cost Solid-State Drives Hard Disk Drives Tape Lower Cost Cloud 4 © 2013 IBM Corporation
  5. 5. Automated Sub-LUN Tiering within a Storage Array Problem: SSDs are considerably more expensive than traditional disks Without optimization tools, clients have been over-provisioning them Administrators spend too much time monitoring, reporting, and tuning tiers Solution: Three data relocation functions that enable smart data Solid-State Drives placement to optimize SSD deployments with minimal costs Enterprise HDD 15K and 10K rpm – Sub-LUN Automatic Movement – Entire-LUN Manual Relocation Nearline HDD – Re-balancing Intra-Tier Extent 7200 rpm Pool5 © 2013 IBM Corporation
  6. 6. IBM Easy Tier® Extent Pools can have mixed media 1. Solid-State Drives (SSD) 2. Enterprise HDD (15K and 10K RPM) 3. Nearline HDD (7200 RPM) SSD RAID Array(s) Easy Tier measures and manages activity – 24 hour learning period – Every five minutes: up to 8 extents moved • Hottest Extents moved up to SSD • Coldest Extents moved down to slowest Enterprise HDD Disk – New allocations placed initially on fastest HDD A small amount of SSD (as little as 3%) can dramatically reduce response times and increase IOPS throughput Nearline HDD Storage Tier Advisory Tool can estimate benefits of adding SSD before purchase!6 © 2013 IBM Corporation
  7. 7. IBM Easy Tier Application Transaction Improvement No change to the database 240% from or application Original brokerage No work to transaction identify active indexes No manual Application Transactions movement of files or volumes Just turn it on Easy Tier In Action and let it Easy Tier work!

  8. 8. IBM Easy Tier® Cooperative Server Caching To avoid performance bottlenecks over the SAN, IBM Easy Tier® will be extended to support server-based Flash Server Server • Most active data will be moved from SAN disk system to server SSD • Global cache statistics maintained in the Disk array • Applications can provide “hints” IBM Edge 2012 Demonstration showed POWER7 server with EXP30 SSD and SSD DS8800 Easy Tier, resulting in 5x performance boost for Filenet ECM Ent HDD IBM has acquired Texas Memory Systems, and plans to offer Easy Tier NL support for PCiE Flash cards as well HDD Announcement : bin/ssialias?subtype=ca&infotype=an&appname=iSource&supplier=877&letternum=ENUS ZG12-01638 © 2013 IBM Corporation
  9. 9. IBM SmartCloud Virtual Storage Center (VSC) Problem: Solution: High-end disk arrays are SmartCloud VSC can manage up to 256 expensive arrays (IBM and non-IBM) per SmartCloud VSC cluster Difficult to identify which data should be moved Storage Analytics Engine recommends up-tier and down-tier moves based on Manually re-locating LUNs performance and age of the data is manual and disruptive Move LUNs non-disruptively within and across arrays SSD Ent SSD HDD Ent HDD NL HDD SAN NL NL HDD HDD9 © 2013 IBM Corporation
  10. 10. Hierarchical Storage Management (HSM) Problem: Disk faces challenges for density and has slowed to 20% Tape will continue to grow in Density at an average 40% CAGR Cost difference – Disk is 20x more expensive than Tape Hard Solution: Disk Drives Migrate or archive data from disk to tape based on age and anticipate access pattern Tape Automatically recall data back to disk when accessed by user or application10 © 2013 IBM Corporation
  11. 11. Blended Disk and Tape Storage Solutions Reduced Costs, IncreasedUtilizing Tape Drastically Reduces TCO Flexibility10 year TCO example. Assumes 250TB storage, 25% growth/yr Lower costs primarily from: $7 – Lower cost of media $6,365,950 Floor space – Minimal need for Power & Power & Cooling Cooling Maintenance Prod + DR Carts Increased flexibility from ability to:Millions Hardware $3.5 – Add capacity by simply adding Tape cartridges $2,255,346 – Expand Tape libraries over $946,405 and around existing equipment in the data center $0 Reliability: lower bit-error-rates, NL/SATA Tape Blended Disk Disk read verifications after writes. and Tape * TCO estimates based on IBM internal studies. 11 © 2013 IBM Corporation

  14. 14. Hybrid Cloud Storage and the IBM Active Cloud Engine™ Problem: Solutions: Remote offices need A Cloud Storage Gateway can provide high access to corporate data performance access to most recently accessed data Corporate HQ needs access to Remote office – IBM SmartCloud Enterprise Object data Storage Data access across WAN can be slow or difficult to find IBM Active Cloud Engine provides a global namespace of all your files across all of your locations Hard Disk – Hub-and-Spoke design allows a central Drives HQ location (Hub) to work with up to 1000 remote offices (Spokes) Cloud14 © 2013 IBM Corporation
