The document discusses real-world design examples for virtualized SAP environments. It provides examples of sizing virtual machines for legacy OS and database migrations. It also shows logical cluster designs including high availability and fault tolerance configurations. Storage designs and disaster recovery plans using VMware Site Recovery Manager are presented. Monitoring SAP environments with vCenter Operations Manager is also covered. Finally, the document discusses how SAP Landscape Virtualization Manager can be used to manage virtualized SAP landscapes.

vCenter Operations Manager – Example SAP Dashboard

DB Response Time

DB CPU Read Latency

22. 2222
Example SAP Dashboard – “Under Abnormal Workload”
DB + App tier health score down
Central Services OK
Response times on one app
server very high !!
Batch activity
is up
SAP Application Hierarchy – drill-down for details

23. 2323
Example Performance Patterns to Observe in SAP Dashboard
 SAP Response times vs I/O Latency
• If DB I/O Latency high > 20 ms but SAP response times within SLAs -> may
not be so critical
 Batch Utilization goes up above baseline
• Check database CPU utilization (SPOF) + health of app tier
• Check SAP response times are within SLAs
 Total user count goes up above the normal baseline
• Check utilization of Central Services VM (SPOF)
• More users could mean more locking
• Central Services may be in 1 x vCPU protected by VMware FT
 Response Time not balanced across app servers
• SAP admin may need to investigate, could be users not balanced evenly
• Note previous dashboard does not have users by app server, easy to add
