What ever happened to the Catalyst 6500 being the premier data centre
switch? 720gb backplane and specific products designed just for data
centres.

Our server farm connects into the network at the distribution layer,
where we typically have better equipment and higher bandwidth
backplanes. In our case, we use 4500 switches with Sup4s, which has
been an excellent combination supporting over 300+ servers, mainframes,
minis, AS400s, etc.
The 3750 series switches should also be a pretty good solution in this
situation but the backplane will be much less than a more robust chassis
switch. Be conservative on the number of switches in a single stack
since I seem to recall the backplane in a stack runs at 32Gb.
I would not directly connect anything directly into the core except for
distribution and other core switches. Sometimes the demarcation point
is not clearly defined so if your core and distribution layers are
collapsed into a single device or layer then really, from an
architectural perspective the 3750 stacks would be considered access
layer but the reality is that they are still only a single hop away form
the core so don't get too wrapped up into the terminology.

Hello Guys,
I'm struggling trying to convince my boss on the issue of choosing a
design over the other.
Basically, we want to make a decision on whether to connect our
Servers(about 250 of them) into our Core/Distribution Layer Switches OR
to connect them into an access layer switch and then provide uplinks to
the core that way.
>From my own experience and knowledge, I prefer the option of segmenting
the server farm and then connecting the access layer switches to the
distribution layer rather than plugging all the servers directly into
the core switches. I know this is a basic design principle question, but
to be honest, I've had a look around on the internet and there is no
such document that states the best practise to executing this. Our
Core/Distribution Switches are 6500 series, We intend to purchase the
3750G Series to provide 1Gbps link for the server. We can then create
gigabit uplinks between the 3750G Switches and the 6500 Series, does
this sound like agood idea?
Many Thanks
