Structured cabling in each rack running back to an mdf cable only rack and then patch tailed into 6500 is a sweet setup as well

A lot depends on the cabling.  Running a few hundred cat5 cables from
several racks into one might be a real pain.  If each rack of servers
can occupy 48 ports or less, and 4948 with 10gig uplinks might be much
cleaner.  6513 wouldn't be a good choice regardless, can't put 6700
series blades in some of the slots.

        What is the 'defacto' top of rack 10/100/1000 48 port access
switch most folks are buying up these days from the big C?

        Does anyone recommend any lower cost 10/100/1000 switches from
other vendors that 'work just fine' for this limited purpose?

        These 48 port switches would just be used to connect machines to
VLANs (over uplink/trunks) which are on the distribution/core layer.

      If you have the right server/client density does it ever make
sense to use a 6513 for the l2 connectivity or is it always better to
use sep. switches?

      It seems like using 11 sep. switches would add a lot of management
headaches over just having a redundant 6500 (pwr/sup) does anyone have
any opinions/advice on this point?

       Thanks!

       -Drew
