For more information on Storage Manager, Powered by Profiler, visit: http://www.solarwinds.com/storage-manager.aspx With the advent of virtualization,more demands are being put on storage to support a complex and dynamic infrastructure, creating new challenges that leave traditional management methods and tools in the dust. Storage Manager 5.1 adds new capabilities and feature to addresses these challenges with end-to-end visibility into your physical resources. Join SolarWinds for a webcast to see how to leverage Storage Manager to take your storage infrastructure to the next level. We will discuss: • Performance Management - Identify the busiest LUNs in your environment, and if the cause is VM or storage configuration. • Capacity Planning - Analyze storage allocation and usage across all levels of the infrastructure. • Reclamation - Identify resources you can reclaim or reconfigure to reclaim space. • Integration with Virtualization Manager - see how to drill from Virtualization Manager right to the specific LUN supporting in Storage Manager

Managing Performance and Capacity

» Garret Gross – Senior Support Engineer
 Today’s Topic
» Managing Storage Capacity and Performance

3.  Can you hear me now?
 If not, use the GoToWebinar chat or Q&A
panel to let us know.
 How do you ask questions?
 Will this thing be recorded?
 Ask lots of questions

4.  The storage virtualization journey
 Pinpointing and resolving new storage
performance hotspots
 Forecasting shared storage capacity issues
 Optimizing and reclaiming space
 Integration with Virtualization Manager

Storage Management for Virtualized Infrastructures
• What VMs are using what • What data is accessed most and least • What departments are using how
physical storage? frequently? much storage?
• Where are my Free LUNs ? • When will I run out of physical storage? • Am I ready for chargeback?
• What can I reclaim right now? • How much more do I need to buy? 5
• Have I automated as much of my
• Where’s the hotspot and how do • “What-if” I add more hosts or VMs? management as possible?
I fix it? • Where should I place these new VMs?

6.  With virtualization, performance of your arrays is critical
» Capacity (storage and I/O) is now shared >> Problems in one area affect others
 Critical needs
» Visibility deep into the array, analyzing the performance at every level (array,
controller, RAID group, LUN and disk)
» Quick identification of problems and bottlenecks
 For example
» If you have server, host or VM hogging storage bandwidth, need to find it
immediately and map it to your physical storage
» Also need to see what else the problem will impact and identify available
capacity you could leverage for a quick migration.

End to end mapping of the virtual & physical environment from VM
to Array disks allows for quick diagnostics of bottlenecks, identifying
resource hogs, and properly allocating and managing your storage.

10. Where’s the Bottleneck?
 Best Practices for Finding Storage Bottlenecks
» Use the Top Ten reports
» Set thresholds, alerts, filters, and notifications to recognize and correct issues
before users experience performance degradation or availability issues
» Manage across your entire Storage Infrastructure: Virtualization, FC Fabric and
Arrays (including EMC, NetApp, Dell, IBM, HP)

12. Capacity Planning for Shared Storage
 Need to be able to quickly and easily pull usage data
from multiple arrays into a single view
» Analyze capacity, allocation, usage and forecasting at all levels
of the storage environment (Raw, RAIDed, LUN, Datastore and
file system)
 Quickly answer key questions
» How much storage do I have?
» How fast is it growing?
» Who is using the most?
- Slide 12 -

13. Other Capacity Considerations
 Thin Provisioning
» How much risk am I incurring by leveraging thin provisioning?
 Storage Tiering
» Understand how you are using your unstructured storage
» What data is accessed most and least frequently?
» Can I move least accessed data to lower tiered storage
devices?
- Slide 13 -

14. Storage Reclamation
 Array:
» Free LUNs – LUNs carved but not in use
 Servers/Hosts
» Unformatted storage
» Orphaned VMDK
 Drive/File System
» Identify specific files that you are interested in, e.g.,
• All MP3 files
• All the files that are at 1MB that have not been accessed in a year.

16. Virtualization Manager Integration
 Quickly drill down from Virtualization Manager to the STM
Target View.

» Cluster
» ESX
