IBM has just released a Redbook with detailed implementation instructions for JS23 and JS43 IBM BladeCenter blade servers. The 594-page guide (yes, 594) is good both for an overall look at the IBM BladeCenter platform, as well as detailed implementation guidelines for specific operating systems (in addition to IBM i, it also has chapters on AIX, Red Hat Enterprise Linux, and SUSE Linux).
The chapter on IBM i implementation is about 100 pages.
