"Unix vendors, faced with the growing threat of Linux
and open systems hardware, have introduced more powerful versions
of the operating system, and promise even better support for data
center-critical business operations.
"While the front end of many networks use Windows or Linux,
Kuznetsky says back-end systems are typically Unix. He says Unix
grew from 54% to a 57% share of overall operating system revenue in
2000.
But most important is IBM's adoption of Linux. AIX 5L has 'Linux
affinity' - the ability to run recompiled Linux programs on
Power-based servers, as well as future 64-bit Intel Itanium PCs and
servers."
