This document discusses VMware View performance and best practices. It outlines enhancements in VMware View 5.0 and vSphere 5.0 that improve performance and consolidation ratios for virtual desktop infrastructure (VDI) deployments. These include improved CPU and memory optimizations in vSphere 5.0, storage tiering, protocol optimizations in View 5.0 that reduce bandwidth usage by up to 75%, and new features like 3D graphics support and performance monitoring tools. The document also provides recommendations around guest optimizations, network sizing, and other best practices.

13. Outline Platform Enhancements Platform Enhancements and Best Practices

14. CPU and memory consolidation vSphere 5.0 achieves more consolidation compared to vSphere 4.1 Scheduler optimizations help CPU consolidation Memory footprint reduction helps memory consolidation HP BL460c blade 8 Nehalem cores 96GB RAM 1GB vRAM/desktop ESX 4.1: 11 Windows 7 VMs per core ESX 5.0: 14.5 Windows 7 VMs per core

15. CPU Scheduler improvements in ESX 5.0 Better out of the box CPU scheduling for VDI workloads No need to tweak scheduler parameters Full and efficient use of CPU, with good QoS

16. Memory improvements in ESX5.0 Virtual machine book keeping memory has been significantly reduced in ESX5.0 This enables higher consolidation ratios E.g. Number of 1GB VMs without overcommit (Ignoring ESX memory footprint)

17. Further savings from page sharing and ballooning Usually able to run more than the calculated number of VMs, up to 20% more depending on applications/load Conservative ballooning in ESX 5.0 further improves memory consolidation

18. So how far have we come in one year ? HP BL460c blade 8 Nehalem cores 96GB RAM 1GB vRAM/desktop Last year, 13 Windows XP VMs per core (ESX 4.1) This year, 14.5 Windows 7 VMs per core (ESX 5.0)

19. Storage Tiering Persona Disposable OS Image Persona VMDK Disposable VMDK Replica VMDK Child OS VMDK (Parent) Regular Datastore SSD Datastore

20. Tiering data distribution “90/10” distribution of IOPS for a freshly created desktop pool Maximize the SSD resource usage by using it for other purposes E.g. File Servers

21. Best practices CPU Up to 14.5 Windows 7 VMs per core for light to moderate Office applications What is good for your scenario ? You can use View Planner tool with custom applications Memory More Windows 7 VMs on ESX 5.0 compared to ESX 4.1 (8% to 15% depending on VRAM size) On top of that, our memory saving techniques can get you up to 20-30% more VMs Storage Use SSD disks to store replicas

22. View Composer Provisioning Improvements Increase provisioning concurrency
