33
Audience Analysis
 How many of you are virtualizing SAP?
 Are you virtualizing DB and App?

44
SAP Virtualization Trends
 No longer relegated to DEV/TEST
 Entire stacks (DB & APP)
• DBs are supported
 Small, medium and large SAP customers
across all verticals are doing it!
 Traditional infrastructure challenges addressed
 Top down push as it helps the bottom line
SAP Adoption Rate

55
What Is Driving the Adoption?
 vSphere 5.x can scale up to 64 plus processors
 Increased cores per socket
 Overhead in SD benchmarks and HANA tests within ~10%
 Simplified HA with APP awareness
 Robust DR with VMware SRM
 SAP/VMware Services Alliance

66
SAP Design Examples
 Sizing for Legacy OS/DB Migration
 Logical Cluster Design
 High Availability & FT
 Storage Design

SAP Monitoring Overview
 SAP Application performance counters
“CCMS” module, examples:
• App server Memory usage
• App server & DB response times
• Batch utilization
 Guest OS Counters
• Memory consumption; SWAP; run queue
 Virtual Counters
• I/O latency (DAVG/KAVG)
• CPU Usage; %ready

vCenter Operations Manager – Example SAP Dashboard
Online Response Time
DB Response Time
App Srv 1 App Srv 2
DB CPU Read Latency

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

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
