Before knowing consistent and acceptable performance of Virtual Desktop Infrastructure / VDI, it is necessary to know, how u can use products from VMware, Cisco, and EMC to
create an end-to-end solution for VMware View. VMware View provides the best end user experience, and transforms IT by simplifying and automating desktop management. Unlike other desktop virtualization products, it is a tightly integrated end-to-end solution built on the industry leading virtualization platform, allowing powerful business continuity and disaster recovery features to their desktops and standardize on a common platform from the desktop through the datacenter to the cloud.
As u mentioned ur Q, performance for VDI environments, especially during peak load periods…., Reference Architecture Workload Code / RAWC is a simulation tool that provides a realistic and customizable application workload to simulate expected VDI utilization in a given server environment. Needless to say that, it generates the required random workload allowing to analyze CPU, Memory, and Disk utilization method, & of-course produce VDI sizing recommendations. It may also introduce random delay or pauses during peak load times.
When the Q arises for workload planning for VDI performance, consider various user types and display protocols as well as.
NOTES: It categorizes the workers into three main types: Task Workers, Knowledge Workers, and Power Users. RAWC workload runs on a Windows 7 or XP guest operating systems.
