Thus far, I have had to re-think operations, maintenance, and disaster 
recovery.  As I develop software, I must re-think storage.

I do not use SELinux, so I do not know.

I suggest doing an inventory of existing equipment and facilities. 
Then, compute replacement costs.  Then document ongoing operations and 
maintenance activities,  Then, compute ongoing operations, maintenance, 
and personnel costs.  Use this data to plan the new data center.

Every person is going to have a different definition of "ideal".  The 
starting point is identifying and applying metrics for measuring what 
matters to your company (and to your customers).  Again, I suggest 
computer and network monitoring systems.

This is arguably the best general book in its subject area.  Everyone 
involved in the computer industry can benefit from reading it, 
especially managers and investors:

I liked this book for its specificity.  There are many books available 
in this subject area, often connected to a "quality system".  However, 
be warned that many people resist formal processes, and those that are 
supervisors may become offended by a subordinate who suggests such:
