Quest vWorkspace Integration and Scalability with Microsoft Hyper-V and System Center Virtual Machine Manager

The goal of this study is to validate the scalability of a virtual desktop infrastructure built on Quest vWorkspace and Microsoft Hyper-V, integrating with Microsoft System Center Virtual Machine Manager to automate management and provisioning of Windows 7 virtual desktops. The tests and simulations focus on how the end-to-end solution scales under high load.

integrating with Microsoft System Center Virtual Machine Manager to automate management and provisioning of Windows 7 virtual desktops. The tests and simulations focused on how the end-to-end solution scales under high load. In June 2010, Quest completed this study at the Enterprise Engineering Center, Microsoft’s premier customer-facing product validation facility.
This report focuses on scalability and integration of the system components. Further studies to be performed in Q4 2010 will focus on performance optimization and even larger farm sizes.

The diagram below shows the relationship between the key infrastructure pieces used in the test. A group of client computers initiates 1,024 remote desktop sessions to Windows 7 VMs hosted on 16 Hyper-V host servers, through the Quest vWorkspace connection brokers. vWorkspace is also used to create, delete, start and stop all Windows 7 VMs, working through System Center Virtual Machine Manager. Each Hyper-V server contains eight hard disk drives, six of which are dedicated to storage of virtual disk images for the Windows 7 VMs in a RAID 0+1 configuration. All VMs use ―child‖ differencing disk images linked to a master parent image stored on each host.

Automated power, logon/logoff and VM provisioning operations were used to validate Quest vWorkspace’s ability to integrate and scale in large VDI deployments using Microsoft’s virtualization solutions, System Center Virtual Machine Manager and Hyper-V. The tests discussed in this paper revolved around a ―building block‖ containing one SCVMM server, 16 Hyper-V hosts, and 64 Windows 7 virtual desktops on each Hyper-V host, for a total of 1024 virtual desktops. Multiple building blocks can be joined to a vWorkspace farm for massive scalability from a single console.
