Simplified installation systemIntegrated server management systemWe ensure that a lack of prior GNU/Linux server administration experience is
not a problem at all. The EasyPush Server Manager (our server management system) simplifies day-to-day server administration and monitoring tasks. EasyPush allows a server admin to build up upon their knowledge of server administration and learn more about GNU/Linux.
Built-in LDAP supportdeepO
fix is one of the first (and few) GNU/Linux operating systems that ship with built-in and pre-integrated support for LDAP. LDAP support in deepO
fix goes beyond installation - in deepO
fix LDAP is not just installed, but also configured as the default store for user account data and password information. LDAP support not only enables deepO
fix to be highly scalable, but also ensure a large group of features that would otherwise have been impossible.

Answer:Any server intended operating system: NT4, 2000 Server, 2003 Server, 2008 Server, OS/X, Linux, FreeBSD, NetBSD. The hard part about servers is matching the load (amount of work), the hardware (as low cost as possible yet still accomplish the goal), and the operating system (cost, ease of administration, stability and security) against your needs now and for a specific period of time into the future: a year, 2 years, 5 years. That's what infrastructure engineers do - they optimize the use of machines against load and future use.
The best system to use is one that whomever is administering the system knows - you can have the best op system and if the admin can't use it right (not experienced with it) you might as well open your windows and doors to the world "come on in, get our data!" or go the users and say "sorry, the server will be going down all the time randomly, expect it."
