A Few months ago we did a bakeoff between Vmware VDI and Citrix Xendesktop solution.
Few things that are worth a mention for differences between these:
1. Citrix ICA protocol for remote desktop connectivity is better with multimedia apps than RDP 5.x.
2. Both RDP and ICA are bandwidth hogs, ICA might be slightly better over low latency link. Average bandwidth usage over WAN without any policing/acceleration technology was 300kbps with both ICA and RDP.
3. Citrix Presentation server has a great option of saving the disk space for multiple cloned desktops and also upgrading/patching only one master image and refreshing all desktops from it.
4. Citrix Access gateway for secure connectivity from outside seems like a separate purchase.(didn’t test it)
We didn’t go ahead with the whole project at that time.
Now Vmware has announced availability for VMware view that addresses point # 1,3 and 4 above. We are currently doing a bake off of vmware view and I will soon post how it went.

VMware lately published a whole bunch of must read technical papers:
Storage Design Options for VMware Virtual Desktop Infrastructure
Companies planning to deploy VDI face decisions about the use of both local and shared storage,
and in the case of shared storage solutions, choosing between differing technologies available in
today’s market. Selecting the appropriate storage model is important for both performance and costs reasons. Certain solutions require less overhead than others, as do different implementations of the same technology. Costs can vary greatly depending on which storage options are chosen. Fortunately organizations can leverage a myriad of best practices to help drive these costs down, while improving performance. This paper provides information on technical concepts related to storage implementations in a VMware ® Virtual Desktop Infrastructure ( VDI) environment.
VMware View Reference Architecture Kit
This reference architecture kit is comprised of four distinct papers written by VMware and our supporting partners to serve as a guide to assist in the early phases of planning, design and deployment of VMware View based solutions. The building block approach uses common components to minimize support costs and deployment risks during the planning of VMware View based deployments.
SQL Server Workload Consolidation
Database workloads are very diverse. While most database servers are lightly loaded, larger database workloads can be resource-intensive, exhibiting high I/O rates or consuming large amounts of memory. With improvements in virtualization technology and hardware, even servers running large database workloads run well in virtual machines. Servers running Microsoft’s SQL Server, among the top database server platforms in the industry today, are no exception.
Using IP Multi Cast with VMware
IP multicast is a popular protocol implemented in many applications for simultaneously and efficiently delivering information to multiple destinations. Multicast sources send single copies of information over the network and let the network take responsibility for replicating and forwarding the information to multiple recipients.

VMware launched the latest version of its Virtual Desktop Infrastructure (VDI) suite, once known as Virtual Desktop Manager (VDM), now being called VMware View. The new product adds features and tools to help better manage physical and virtual clients, storage, and enterprise applications.
The release demonstrates VMware’s commitment to desktop virtualization in 2009. During September at VMworld 2008, VMware President and CEO Paul Maritz announced the company’s new desktop initiative and dubbed it VMware vClient saying that it would solve the “desktop dilemma.” The vClient initiative is part of several new product offerings to help VMware keep control of the virtual datacenter.

With VDIworks2Go, we’ll be able to support seamless virtual machines check-in and check-out. In effect, VDIworks2Go installed, VDP’s connection brokering interface will let you inform the system that you are about to disconnect from the network and hence need a checked out copy of your VM. The VM gets streamed over to you and executes locally using a virtual machine player. When you reconnect to the network, you can check the VM back in so that it can execute on a fast server, without taking up your local resources. Read more

Desktop Virtualization: VMware Adds To VDI Protocol Collection
— VMware is collecting protocols. Last week it made Teradici’s day and announced that it had licensed the software implementation of the Canadian start-up’s PC-over-IP display protocol technology as a key piece of its so-called PC-replacing vClient initiative.
