What Should i Buy?

I currently have 20 client computers connected to a central server. I wish to upgrade the network (currently on 10/100 switches and a Dlink DFL-700 router) to make it go faster what would u guys suggest?

More about what
  1. Perhaps a Cisco 3750.
  2. Do the workstations or the server have gigabit nics in them? If not, upgrading the networks speed may be quite a bit more costly than just replacing a switch :)
    I'd go for either of these nics for the workstations:
    Intel PWLA8391GT - $35
    3com 3C2000-T - $47
    And one of these for the server:
    Intel PWLA8490MT - $99
    3com 3C996B-T - $125

    For just a 20 user network you dont really have to shell out for cisco (unless you have serious bucks, then go for it).
    A 24 port netgear should be just fine. The NETGEAR JGS524FNA ($260) would probably fit your needs and it has two mini gbic slots for any future fiber expansion ;)
  3. Yes all the workstations have gigabit nics on them, thanx for the help

    <Gag!> Sorry. Wow.. I hope that was joke. A 3750 costs... well... a lot.

    The main things I think you need to look for are at least a 24port (if not larger) 10/100 port switch that also has a couple of GigE ports. It's *really* important to look for a switch that's advertised as having a "non-blocking" architecture. What this means is that the switch-fabric/backplane of the switch has the same bandwidth as the sum of all it's ports. Basically... everybody can talk at the same time without any bottlenecks. Lesser/older switches don't have that feature.

    So, like a 24+2 or a 48+2 switch will allow all your PC's to communicate at full throttle. You can even hook up the server via GigE to one of the GigE ports since that's a choke point for multiple users hitting it at once.

    Tom's Networking just did a review on a decent NetGear switch that could fit the bill:

    NetGear also makes a 48port version.
  5. hehehe.... he didn't say anything about keeping the cost down... and I was being realistic. I could have said a 7609 with dual sup720 bxl3s and 6724 sfp mods...
