It's the uplinks from the servers that matter, so your 6 gig backbone
capacity will support at least 6 servers at full bore on their gig
uplinks, so 200 clients before any possible contention if they are
distributed over additional switches connected on their gig ports.
And in practice you can probably do 10x that before you would notice
any slowdown on that switch.
