Performance Sizing Variables Number (Connections/User x Concurrent User % x User Population) Of = ------------------------------------------------------------------------------------ X (1 – Cache %) Servers Server’s Maximum Concurrent Connections Example: Average connections per user: 3 Concurrent Users on Internet: 33% User Population: 15000 users Dell 2950 Server (8 Cores, 8G Ram): 6700 Cache Percentage: 0% (no caching) (3 x .33 x 15000) # of Servers = ------------------------------ X (1 - 0) Equals: 2.22 servers 6700 max cps (Dell 2950) Round up to nearest whole server: 3 Dell 2950 servers

  20. Calculating Maximum of Users per Server Maximum Server’s Maximum Concurrent Connections # Of = ---------------------------------------------------------------- X Concurrent users % on Internet Users Connections per User Example: Average connections per user: 4 Concurrent Users on Internet: 33% Dell 2950 Server (8 Cores, 8G Ram): 6700 6700 max cps (Dell 2950) # of Users = ------------------------------------ Equals: 5075 users maximum for this server (4 x .33)

  21. Supporting IxSVA Products Under VMware • Create Virtual Machine • Install SVA Application • Performance Tune Virtual Machine (if necessary) • Troubleshooting Tips

  22. Installation on VMware ESX • Upload the IWSVA CD image to VMware server • Create a New Virtual Machine and assign resources • Bind CD ISO to CD autostart and start Virtual Machine • Go through the Installation Process

  23. Login and Upload the IWSVA ISO Image

  24. Create the Virtual Machine

  25. Install IWSVA

  26. Performance Tuning - VMware ESX • Performance tune ESX, VMkernel, Guest OS • Install VMware Tools to Guest OS for memory management • Allocate resource pools for the application • Use the Trend Micro product readme as a guide for resource allocations • Configure the Virtual Machine to use Virtual SMP • For high throughput applications (IWSVA, IMSVA) • Use 2 or more physical network cards for the vSwitch where the products are connected to • Use only 1Gbit physical network cards

  27. Performance Tuning - VMware ESX • Underlying hardware needs to be utilized according to best practice • Use high performance RAID storage where possible • 15K RPM disks • Large Stripe Size • For networking • Use gigabit only • One dedicated connection for console access • Two or more dedicated physical NIC’s per configured vSwitch

  28. Performance Tuning - VMware ESX • Avoid the VMkernel swapping • Monitor /proc/vmware/swap/stats file. If constantly over 0, add more physical memory • Tuning the Guest OS can offer significant performance improvements • Install VMware Tools • Disable unused services in OS • Disable unused hardware in virtual machine profile • Use SCSI for disk type profile

  29. Performance Tuning – Guest OS • One main function of VMware Tools is to deallocate memory from selected virtual machines when RAM is scarce ample memory; balloon remains uninflated inflate balloon Driver demands memory from guest OS Guest is forced to page out to its own paging area; VMkernel reclaims memory deflate balloon Driver relinquishes memory Guest may page in; ESX Server grants memory

  30. Virtual Machine Resource Pools • Resource pools allows VMware ESX to pre-allocate compute and memory resources for dedicated use • For IWSVA it is best to allocate the following for a resource pool • 4096Mb RAM • 3000Mhz • If no resource pool or reservation is defined, 50% of configured requirements is captured for that VM

  31. VMware ESX Guest OS Performance Monitoring • Use the VI3 Client to view Guest OS performance • Change chart options to gather the statistics you are after

  32. Troubleshooting and Fault Analysis • Virtual machine problems can be caused by • Not enough physical resources • Not enough virtual resource available (allocation issues) • Guest OS or application failures • Misconfigurations

  33. Q&A
