  14. 14. CPU and memory consolidation<br />vSphere 5.0 achieves more consolidation compared to vSphere 4.1<br />Scheduler optimizations help CPU consolidation<br />Memory footprint reduction helps memory consolidation<br />HP BL460c blade<br />8 Nehalem cores<br />96GB RAM<br />1GB vRAM/desktop<br />ESX 4.1:<br />11 Windows 7 VMs per core<br />ESX 5.0:<br />14.5 Windows 7 VMs per core<br />
  15. 15. CPU Scheduler improvements in ESX 5.0<br />Better out of the box CPU scheduling for VDI workloads<br />No need to tweak scheduler parameters<br />Full and efficient use of CPU, with good QoS<br />
  16. 16. Memory improvements in ESX5.0<br />Virtual machine book keeping memory has been significantly reduced in ESX5.0<br />This enables higher consolidation ratios<br />E.g. Number of 1GB VMs without overcommit (Ignoring ESX memory footprint)<br />
  17. 17. Further savings from page sharing and ballooning<br />Usually able to run more than the calculated number of VMs, up to 20% more depending on applications/load<br />Conservative ballooning in ESX 5.0 further improves memory consolidation<br />
  18. 18. So how far have we come in one year ?<br />HP BL460c blade<br />8 Nehalem cores<br />96GB RAM<br />1GB vRAM/desktop<br />Last year, 13 Windows XP VMs per core (ESX 4.1)<br />This year, 14.5 Windows 7 VMs per core (ESX 5.0)<br />
  19. 19. Storage Tiering<br />Persona<br />Disposable<br />OS Image<br />Persona VMDK<br />Disposable VMDK<br />Replica VMDK<br />Child OS VMDK<br />(Parent)<br />Regular Datastore<br />SSD Datastore<br />
  20. 20. Tiering data distribution<br />“90/10” distribution of IOPS for a freshly created desktop pool<br />Maximize the SSD resource usage by using it for other purposes<br />E.g. File Servers<br />
  21. 21. Best practices<br />CPU<br />Up to 14.5 Windows 7 VMs per core for light to moderate Office applications<br />What is good for your scenario ? You can use View Planner tool with custom applications<br />Memory<br />More Windows 7 VMs on ESX 5.0 compared to ESX 4.1 (8% to 15% depending on VRAM size)<br />On top of that, our memory saving techniques can get you up to 20-30% more VMs<br />Storage<br />Use SSD disks to store replicas<br />
  22. 22. View Composer Provisioning Improvements<br />Increase provisioning concurrency<br />

  30. 30. Performance Comparison with Other Protocols<br /><ul><li> PCoIP provides better user experience in all network conditions
  31. 31. RDP7 doesn’t perform well in extreme WAN</li></li></ul><li>Performance Comparison with Other Protocols<br /><ul><li> PCoIP consumes lower or at-par compared to PortICA and RDP7
  32. 32. RDP7 cripples the video and web-album – bandwidth could have been more</li></li></ul><li>Performance Comparison with Other Protocols<br /><ul><li> PortICA consumption is higher across all network conditions
  33. 33. PCoIP is lower, RDP is lower in extreme WAN because of excessive crippling</li></li></ul><li>Gain insight for troubleshooting and issue resolution<br />Overview<br /><ul><li>Per session statistics to monitor protocol performance and network impact
