Need For Speed- Using Flash Storage to optimise performance and reduce costs- peter mason

  1. 1. Flash Storage: The Need For Speed Peter Mason NetApp UK 1
  2. 2. Disk Trends over the Years  1956 75KB, 1200rpm, 176B/sec  1973 100MB, 1500rpm, 800KB/sec  1985 700MB  2003 72GB, 7200rpm, 80MB/sec  2013 600GB, 15000rpm, 180MB/sec Increase of x 6.6million capacity, x 1million performance Last 10 years x10 (or more) capacity, x2 performance  Then came Solid State Drives, 500MB/sec 2
  3. 3. Random IOPS and Latency  SAS delivers around 180 IOPS – Typical latency of 1 msec to 20+ msec  SATA delivers around 40 IOPS – Typical latency of 4 msec to 20+ msec  SSD delivers around 10000 IOPS – Typical latency of under 1 msec NetApp Confidential Information, not for distribution 3
  4. 4. Flash Market Segments All Flash Array Flash only Server Cache Hybrid Array HDD + Flash storage Traditional Array HDD only Latency Requirements Capacity Requirements  Fastest access  Flash for IOPS + HDD for capacity  Slowest access  Lowest $/IOPS  Low latencies for cache hits  Highest $/IOPS  Highest $/GB  Medium $/IOPS  Lowest $/GB  Medium $/GB 4
  5. 5. Traditional HDD Requires Massive Overprovisioning to Deliver Performance Performance Zone of Over-provisioning Over-provisioned capacity SAS SATA Required Provisioned Capacity 5
  6. 6. Hybrid Flash Mitigates the Problem but Zone of Over-provisioning Remains Performance Zone of Over-provisioning Flash acceleration changes profiles Hybrid SAS SAS & Hybrid SATA SATA Capacity Note: Hybrid solutions include flash caching on the server side; in the controller; and in the storage shelves 6
  7. 7. All Flash Arrays are Optimal for High Performance Performance & Low Capacity Workloads All Flash Arrays Zone of Contention HDD + Flash Traditional HDD Capacity 7
  8. 8. NetApp Flash Portfolio All Flash Array Flash only Server Cache Hybrid Array Traditional Array HDD + Flash storage HDD only Complete Portfolio of Offerings for Any Workload EF-Series Flash Accel Flash Cache Flash Pool FAS/V-Series E Series SSD Cache 8
  9. 9. Growing NetApp Flash Momentum 44 PB Flash Sold  33 PB flash as cache  11 PB flash as storage FY 2013 SSD Sales Flash Attach Rates  Deployed in ~25,000 systems  60+% attach for mid/high systems  High end attach >80% Q1 Q2 Q3 Q4 • 9X Year-over-Year Increase • Q4 SSD capacity exceeded Q1+Q2+Q3 combined NetApp Proprietary.

  10. 10. Hybrid Arrays with Virtual Storage Tier 10
  11. 11. Storage Tiers – Beware of the Traps  Tiering of data is a popular hybrid  How long does it take to move data between the tiers?  How much work is involved in defining tiering policies?  What’s the impact on snapshots, backups etc.  How does tiering impact/compliment dedupe/compression 11
  12. 12. Fully Automated Storage Tier  Flash Cache – – – – Cache card(s) - Plug in and Go! Zero configuration required, System-wide No impact on existing operations Real-time, Instant Acceleration  Flash Pool – – – – – SSD acceleration Applicable to a subset of data Configure and Go! No impact on existing operations Real-time, Instant Acceleration 12
  13. 13. The Boot Storm Problem Read data block from disk Disk
  14. 14. NetApp FlashCache – Umbrella for the Storm Boot time decreases 47% Storage workload decreases 50% Performance increases 71% Read data block from disk Disk Flash Cache Users don’t take a hit during simultaneous boot or log on. http://www.youtube.com/watch?v=7FJMNG5VdI8
  15. 15. Flash Cache Customer Value File Services Workload Example Before: Cost/efficiency impact  Entire dataset moved from SAS to SATA disks  34% lower cost per TB FAS6210 HA with 144 TB 240x 600GB 10k rpm SAS disks  40% lower cost per IOPS  40% less power After: Flexibility impact  17% more storage capacity  28% more IOPS FAS6210 HA with 168 TB 168x 1TB 7.2k rpm SATA disks 1 TB Flash Cache  18% improvement in average response time NetApp Proprietary.

  16. 16. Flash Pool Customer Value OLTP Workload Example Before: Cost/efficiency impact  Entire dataset moved from SAS to SATA disks  46% lower cost per TB FAS6210 HA with 144 TB 240x 600GB 10k rpm SAS disks  18% lower cost per IOPS  26% less power After: Flexibility impact  50% more storage capacity  Similar IOPS (± 2%) FAS6210 HA with 216 TB 216x 1TB 7.2k rpm SATA disks 24x 100GB SSDs  Significant improvement in average response time NetApp Proprietary.
