short description:
ONTAP 9 Performance Analyse including case studies and solutions
target group:
Experienced NetApp storage administrators and architects
requirements:
We suggest to visit the training „ST200c ONTAP 9.x Admin Basics" or "ST221c ONTAP 9.x Data Protection & High Availability“ before. Also we recommend to have at least 9 to 12 months experience with ONTAP administration.
objectives:
This training provides basics about the performance analysis on Netapp systems and ONTAP. This includes the NetApp hardware, software and tools for the data analysis.
miscellaneous:
duration: 5 days
price: 4500,- Euro + VAT
Netapp Training Units: 60

agenda:
  • Introducing the following topics:
    • Physical and logical errors: e.g. fragmentation, misalignment, small IOs, reconstructs, silent data corruption
    • Further „anti-bully“, „fairness limitations“ like TCP-Windowsize, buffer credits, quality of service and CMD queue limits for storage
    • What are the effects?
    • How can we recognize them?
    • Countermeasures from NetApp: lost write protection, free space reallocate, read reallocate, dedupe, compression, compaction, VAAI, ODX, thin provisioning

  • The mathematical basics:
    • Queueing theory and the correct use of filer performance analysis
    • Detect Open and closed loads, single threaded & parallel loads at clients
  • ONTAP commands to identify…
    • Highest latencies
    • Highest IO loads
    • Highest data throughputs
    • Biggest queues
  • Performance tuning:
    • HDD + PAM = Flash Cache
    • HDD + SSD = Flash Pool (Hybrid Aggregate)
    • SSD only = All Flash FAS (AFF)
    • Flexgroup
    • Presentation: which optimizations are possible and rational in each case?
  • Sizing:
    • Adequate consideration of the client IOs
    • Estimation of the additional housekeeping IOs from a filer
    • Size of the metadata and the working set

  • Overview of external monitoring tools:
    • System Manager
    • OnCommand Unified Manager with OnCommand Performance Manager
    • Harvest, Graphite, Grafana

  • Troubleshooting configuration errors (HW / SW)
