Citrix announced that more than 10% of Global Fortune 500 companies have downloaded and activated XenServer virtualization platform for production use in the last four months. By providing a free, full-featured alternative that dramatically lowers the entry price of virtualization, Citrix has saved companies of all sizes millions of dollars and provided compelling value to IT organizations as they face shrinking budgets. Anyway, if confirmed, it may be a bomb against the VMware fortress: it’s a well-known fact that one of the biggest VI3.x selling points is its massive adoption in Fortune 100 (100%), Fortune 500 (98%) and Global Fortune 500 (95%) companies.
