White Paper: Design Proposal for Hosted Virtual Desktops

Oracle released a white paper for Oracle VDI: A Design Proposal for Hosted Virtual Desktops. The white paper discusses a design proposal for Windows 7 virtual desktops hosted on Oracle Virtual Desktop Infrastructure. It proposes infrastructure for 500, 1000 and 1500 users.

Topics discussed in the white paper are the high-level architecture, capacity planning and design decisions. The white paper finishes with performance optimizations.

The infrastructure in the white paper is based on the full Oracle stack of products, from the end-user client to the storage in the data-center. 

For the storage tier it discusses the Oracle Sun ZFS Storage appliance and calculations are  presented for IOPS for the virtual desktops.

The virtualization tier is represented by the Oracle VDI built-in hypervisor Oracle VM VirtualBox running on Sun Fire x86 servers.

The session management layer discusses the Oracle VDI core technology. For a 500 desktop deployment, only a 10 core capacity is required for the client sessions. This may be deployed on bare-metal or virtualized on a server-hosted platform. 

Furthermore, the client tier is used by several hardware clients: Sun Ray ultra-thin clients and the OVDC software application running on Windows PCs, Mac OS X and tablet devices such as the Apple iPad. 

The white paper finishes with the following statement: "A complete VDI solution requires tying together server hardware, storage hardware and networking technology, in addition to deploying VDI software. Oracle is alone as a VDI vendor in being able to deliver the complete stack: software and hardware engineered to work together."

I post here hands-on examples which I have used in my Oracle VDI Desktop Virtualization projects at customers and partners.
