Atea Datacenter & Cloud Services (ADC)
Outsourcing – 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
4
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
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
18
TPC - Errors - Defective Disk
The error is caused by a failed 900GB SAS disk

TPC – Storage System Overview
20
TPC – Storage System - Internal Resources
Many options for a quick overview
– Volumes
– Pools
– Managed disks
– FC portes
– I/O groups
– Disks
21
TPC – Storage System Overview
22
TPC - Reporting
23
TPC - Predefined reports - Performance
24
TPC - Predefined reports - Storage Virtualizer
25
TPC - Predefined reports
26
TPC - Predefined reports
27
TPC - Storage Virtualizer - Details Report
28
TPC - Storage Virtualizers - Most Active Volumes
29
TPC - Most Active Volumes – Response time
30
TPC - Most Active Volumes – Response time
31
TPC - Most Active Volumes – I/O Rate
32
TPC - Most Active Volumes – Data Rate
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
34
TPC – Simple Report – Cognos Query Studio
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)
36
Tools til SVC og V7000
SVCMON
– Collecting performance data from V7000 and SVC
SVCFRONT
– PHP Frontend to SVCMON
STAT
– Storage Tier Advisor Tool
37
SVCMON
SVCMON – SVCMON collects SVC/Storwize V7000 performance data, and generates
spread sheet files in CSV format and graph files in GIF format.
38
SVCFRONT
SVCFRONT – A PHP Frontend to the SVCMON script, that provides a drilldown view to your
SVC/Storwize performance data
39
SVCFRONT - Demo

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
– _
