Let's see the math...
Access port speed - 100 Mbps/FDX
Number of ports per 2924 - 24 (23 access, 1 uplink)
Uplink port speed - 100 Mbps/FDX
Oversubscription ratio - 23:1
Assuming you have well behaved clients and network has been properly
segmented (1,500 clients in a single broadcast domain DOES NOT qualify),
with bursty office application traffic and maybe an 80/20 ratio of
silent/active hosts at any one time. That would give approximately per
host, 21.7 Mbps/FDX, worth of uplink bandwidth which is not too shabby at
all.
Do the same type of math to figure out if your server connections are ok at
100 Mbps/FDX... given your example, are the 40-50 servers servicing 1,000 -
1,500 or 30,000+ clients? Are clients roughly evenly distributed among the
servers or are there some servers that every client connects to?
The other aspects to consider is how the client desktops are configured -
Win 95 running every protocol under the sun would sure add a lot of
unnecessary noise (broadcasts especially) to all the client segments.
