Sources for EMC architecture documentation

I'm fairly familiar with general SAN technology (mostly from client
connection side). Being a contractor, I'm sometimes asked to look into
SAN performance metrics, disk layout schemas, etc.... My guess is that
clients are not willing to spend big $$ for SAN specialists and try to
see if "generalists" like myself can resolve some of their storage
issues also.
I never BS unless I have done my homework first. While there is plenty
of online info on Sun/Cisco/Win2k internals issues, I have not found
any good sources for EMC internal architecture, best practices guides.
Please advise.

EMC's customer support site (http://powerlink.emc.com -- free reg req)
has a lot of good information. Other information, like whitepapers and
bp guides, are availble through the EMC SE on the account.

IMHO, the best information along these lines is in the EMC customer
training programs. Some of which, especially the self-study value-pak
programs, are pretty reasonable.

If you have any specific questions, you can query your SE, and possibly
involve a performance expert-- or of course pose those question here...
