Crosby also says Citrix is having more success selling its server virtualization software to desktop customers. As recently as two years ago, 90 percent of XenDesktop buyers were using VMware's ESX virtualization technology on the back end of their server-hosted desktop deployments.
Now, Crosby says about 50 percent of Citrix's XenDesktop revenue comes from customers using Citrix XenServer in the data center, with the rest split between VMware and Microsoft's Hyper-V.
As for XenClient, the software will be available both as a part of XenDesktop and in an already available standalone "express" edition that has the same functionality and can be used for up to 10 desktops free of charge.
Online support will be available for the standalone version, but more extensive support will only be available to customers who use XenClient as part of the XenDesktop virtualization platform. Pricing for XenDesktop 4 as of last November ranged from $75 to $350 per desktop user.
