– Responsible for the overall operation and maintenance of a companies IT
infrastructure. Includes Servicedesk, Netværk, Server, Storage, Change
management – based on ITIL framework
 Infrastructure as-a-Service – IAAS
– A platform in a virtualized environment - as a service, including servers,
network, storage and backup.
 Cloud Backup
– Remote backup solutions

ADC – Storage Environments
Our Storage environment can be divided into
two different categories :
 Outsourcing
– (IAAS, VMware, SQL, Exchange osv.)
 Backup
– (TSM & CommVault)
All storage is based Enterprise, Midrange and Entry level from IBM

TPC – Performance Data

13. 12
TPC at Atea
 June – 2008 (IBM)
– IBM analysis of hardware installation
 February 2009 - 2012 (IBM)
– IBM recommendations in relation to new hardware
(DS800 vs. DS5300)
 April 2013 (Atea)
– TPC 5.1 Installation with new hardware
implementation

TPC – Errors

19. 18
TPC - Errors - Defective Disk
 The error is caused by a failed 900GB SAS disk

20. 19
TPC – Storage System Overview

21. 20
TPC – Storage System - Internal Resources
 Many options for a quick overview
– Volumes
– Pools
– Managed disks
– FC portes
– I/O groups
– Disks

22. 21
TPC – Storage System Overview

23. 22
TPC - Reporting

24. 23
TPC - Predefined reports - Performance

25. 24
TPC - Predefined reports - Storage Virtualizer

26. 25
TPC - Predefined reports

27. 26
TPC - Predefined reports

28. 27
TPC - Storage Virtualizer - Details Report

29. 28
TPC - Storage Virtualizers - Most Active Volumes

30. 29
TPC - Most Active Volumes – Response time

31. 30
TPC - Most Active Volumes – Response time

32. 31
TPC - Most Active Volumes – I/O Rate

33. 32
TPC - Most Active Volumes – Data Rate

34. 33
TPC – Reports
 With the Predefined reports we got
– A quick overview of the system
– A bit more specific look at the performance of specific disks
I/O - Latency - Data Rate
 To get more specific reports
– Create a basic report using - Cognos - Query Studio
• Build own specific reports
• Create templates for general reports
 Hint:
– The Predefined reports can be used as templates in Query Studio

35. 34
TPC – Simple Report – Cognos Query Studio

36. 35
TPC – Lessons Learned (so far)
 Set Retention
 Collect data before and after hardware/software changes
 Export to CSV for later review
 Start wide (sample by hour)
– Get an overview of a period of time (one week)
– Drill Down
 So many options
– IO Rate (ops/sek)
– Datarate (MB/sek)
– Response time (ms/op)

37. 36
Tools til SVC og V7000
 SVCMON
– Collecting performance data from V7000 and SVC
 SVCFRONT
– PHP Frontend to SVCMON
 STAT
– Storage Tier Advisor Tool

38. 37
SVCMON
 SVCMON
– SVCMON collects SVC/Storwize V7000 performance data, and generates
spread sheet files in CSV format and graph files in GIF format.

39. 38
SVCFRONT
 SVCFRONT
– A PHP Frontend to the SVCMON script, that provides a drilldown view to your
SVC/Storwize performance data

40. 39
SVCFRONT - Demo

41. 40
STAT – IBM Storage Tier Advisor Tool
 STAT
– The IBM Storage Tier Advisor Tool predicts whether the addition of Solid
State Drive (SSD) capacity in conjunction with the Easy Tier function could
benefit system performance
• Download Heat filen from SVC/V7000
• Run: “stat dpa_heat.78N2TLT-2.130523.225648.data”
 Result
– System Recommendation
– Storage Pool Recommendation
– _
