Hardware, Embedded Systems IDC's newest survey of server vendors shows boxes running every kind of operating system -- except Unix -- sold more during the last three months of 2010. Sales of Linux servers rose 29 percent; Windows rose 16.8 percent, but most surprisingly, sales of mainframes shot up 69 percent " the highest growth rate IDC ever found on mainframes.

How accurate can this be?

Member since:

In some cases the server vendor owns the OS (IBM & Oracle). How much can we rely on the accuracy of the numbers they report?

Does this take into account systems sold with no OS? Many large companies would have site licenses / support contracts and would not necessarily order the server with an OS installed. Others may be using freely available Linux distro's, a BSD or something else.

Does anyone have any idea how IDC account for the above?
