13. What are Analysts saying…. "It's ironic that the largest, most sophisticated IT shops in the world are the ones most likely to have hidden problems."   "The issue is visibility - or the absolute lack of.  We have no idea what issues we have, and where, most of the time.  When you add virtual services into the infrastructure, you only compound the problem.  It's like driving blind - you can wing it for a while, but sooner or later you will hit something." - Steve Duplessie, Founder, Enterprise Strategy Group.

14. Typical SAN Diagnostic Scenario - Today SAN/Storage Administrators Application Users SAN Vendors Use SRM/SAN Mgt products to try and locate problem Vendor attempts to diagnose over the phone Users report slow application response times and blame SAN Users report slow application response times and blame SAN Y Problem found? Problem found? Y N N Vendor arrives on-site and begins to use vendor’s diagnostic tools Contact Storage Administration Use Device Mgt Tools to try and locate problem Application Performance restored, Users are Happy! Y Problem found? N Y Problem found? Vendor concludes problem is not with their device N Contact next SAN Vendor Contact last problem vendor for help Contact Application Admin. & confirm SAN is not the source of the problem Customer calls meeting with ALL SAN Vendors and pushes for resolution The Vendor most in question arrives with Xgig Analyzer Application Administrators can now eliminate SAN from equation and focus on other potential problem areas (i.e. app changes, DB queries, etc.) Y Problem found? N

15. SAN Diagnostic with NetWisdom – Reactive State SAN/Storage Administrators Application Users SAN Vendors View NetWisdom Dashboard & Reports to see if any SAN Links are experiencing any problems Vendor’s 3rd level support gets trace and diagnosis. Users report slow application response times and blame SAN Users report slow application response times and blame SAN Y Problem found? Problem found? N Contact Storage Administration Y Use Netwisdom to troubleshoot, if necessary Generate Xgig Capture & Trace, Troubleshoot & resolve Application Performance restored, Users are Happy! Y Problem fixed? N Contact Application Admin. & confirm SAN performing within specs Contact vendor in question & email trace Application Administrators can now eliminate SAN from equation and focus on other potential problem areas (i.e. app changes, DB queries, etc.)

16. App Admin. notified SAN Admin are working on problem SAN Diagnostic with NetWisdom – Proactive State SAN/Storage Administrators Application Users SAN Vendors Vendor’s 3rd level support gets trace and diagnosis. Users report slow application response times and blame SAN NetWisdom alerts SAN Admin. to problem & initiates Xgig Capture & Trace Application Admin. alerts users to potential slowdowns Y Problem found? Application Performance restored, Users are Happy! SAN Admin reviews NetWisdom & Xgig Trace Y Problem fixed? N Contact vendor in question & email trace

17. SAN Admin confirms SAN performing within specs NetWisdom – Pre-Production Environment SAN/Storage Administrators Application Users Application Admin. Prepares for App or System change/upgade, etc. Users report slow application response times and blame SAN SAN Admin baselines existing App/System performance Informs Storage Admin. of planned change/upgrade Notifies App Admin ready to monitor the change App Admin. makes change/upgrade SAN Admin uses NetWisdom to Monitor App/System performance for minor changes Y Problem found? N Application Administrators can now confidently roll upgrade/change into Production

30. Solution: Application Availability • Distributed storage systems and the growth of complex SANs make it hard to understand the factors determining application performance • Enterprise IT dislikes the finger-pointing between application, server and storage suppliers • By examining the conversations between SAN components, we can provide clear insight into application performance

31. Application Availability Solution • Pre-installation Application Infrastructure Availability • Verify the infrastructure is working in advance and meets the planned capacity requirements for the application • Application Traffic Analysis • Verify traffic capacity used by the application • Verify traffic is flowing according to failover policy and configuration • Verify traffic is clean – no protocol error pollution from failing devices, overrun queues, CRCs, etc. • Continuous Application Availability • Detect Application traffic slow downs before they impact the users • Correlates application level workloads to actual SAN traffic • Detect impacts to the application traffic after configuration, firmware or hardware changes in the SAN • Detect failing devices • Trend the application traffic capacity • Automated front-end for trace creation for hardware vendor problem analysis
