How do you wire your cabinets?

Stacks are simply not as good as a star topology. Removing the stacks and having a 2824 is your best bet, as you said.

 

Splitting your 2gig uplink to 2 1gig uplinks will provide you with a small increase in speed, but won't help that much.

We have about 10 seperate buildings so we dont have a lot of choice but to have a fibre running to each

 

Currently we pretty much have a star toplogy with 19 seperate fibre links to about 16 cabinets. There are 3 locations where they are still daisy chained: one is an internal fibre link in the maths block, and there is only about 6 devices connected to the switch, one is to the PE office and theres only 4 points there and the other is our humanities which is the only area which is a bit of a bottleneck

 

Its miles better than when I came - in the worst case there was 1x1GB fibre going to the art department (15 macs), daisy chained off that was the tech department (100 PC's) and chained off that was the IT department (32 PC's). So 147+ machines were running off a single connection. Needless to say speeds were ridiculous

 

In the oldest areas there are just 2 pairs terminated to cabinets, in the newer ones 16 or 24. No more than 1 link to each cab though (with the exception of tech) because we just dont have enough capacity on the core switch (see my other posts about that...grrr)

 

Some switches are stacked unfortuantly but until we get more capacity theres not much we can do about that

One campus is a star, and the other is a bus, due to the way that the ducts have been laid. Workgroup switches are stacked, up to 8 units high with 48 ports per unit. I am working toward one distribution switch per building, but I doubt that the necessary ancillary works will be completed before I leave next year.

 

The workgroup switches are arranged like this in cabinets for ease of maintenance and cabling:-

At present the stacks have 1 or 2 gigabit connections to the distribution/core switches. The distribution switches are connected by 4 gigabit trunks, and are upgradable to 10gigabit.

 

While we're on the subject, I have some fibre to dispose of. Single mode, multi mode, and combinations of the two, all suitable for ducting. If you are interested drop me a message.
