PARTNER PoV VDI on the MAINFRAME Hosting virtual desktop on System z can decrease complexity and save costs A s an internal IT provider, independent service provider or hosting partner, your clients seem to all have one thing in common-an increased demand for virtual desktop infrastructure (VDI) solutions. They might want additional VDI solutions or they might want the ones they have to perform better. Quite frankly, most want both. Henri Küiper is an enterprise IT specialist and a certified mainframe junkie. He's founder (and owner) of, technical coordinator at the Guide Share Europe (Dutch Region) and has been a SUSE advisor and consultant for several years. A majority of your clients' user base wants to access their work environment anywhere at any time. Increasingly, they also want to use multiple devices, such as laptops, tablets or smartphones. Many organizations deploy Citrix and/or VMware solutions to provide this service, and most start out by serving a relatively small number of clients with a set user device in mind. Yet, as stated, demand for VDI is increasing, and while most companies just finished their 12 // MARCH/APRIL 2014 server consolidation projects, they're now facing server sprawl when it comes to bringing in the hardware to deliver VDI services. For example, based on various (public) performance and capacity reports, a Citrix environment will provide about 150 user sessions on a fully configured blade server. That means larger user bases require additional servers-and additional intermediate hardware like switches and such-to increase the capacity of the VDI environment. Not only does this lead to an increase in complexity, but it also negatively affects the total cost of ownership. How many VDI sessions can one of these servers provide? And what are the extra costs for going beyond that one server? Companies implementing large-scale VDI infrastructures based on x86 and Citrix/VMware solutions are seeing an increase in complexity and cost. Users are also often unhappy with the performance provided.
