Segmenting the network at this point can have some great benefits.
I would highly recommend putting in store and forward bridges from
each server segment to the Thick backbone. This will allow better
utilization on the independant (now) subnets and also allow fast
problem isolation and operation of most segments in the event of
a faulure on a particular segment.

I have seen networks where segmentation was not done. They worked
fine with low utilizations. As they became more integrated and
relyed upon the traffic levels picked up. Then a failure would
take down everyone at the same time.

Good Luck
