DESCRIPTION
Virtual desktop deployments are some of the most difficult workloads for storage. In this session attendees will learn how seemingly insignificant design decisions can have a great impact on end-user experience and solution scalability. Attendees will learn how integrations between NetApp and VMware can help customers reduce the size, cost, and complexity of VMware View environments. We will demonstrate how desktop administrators can take advantage of these technology integrations without changing their existing desktop management workflows. We will also cover common pitfalls, and how to avoid them; proper solution analysis, architecture and sizing, design decisions and how to ultimately win with View on NetApp.
