Any gigabit ethernet switches...

I've currently got a 10/100Mb/s HUB yes, thats right hub, hooked up to 3 computers+another HUB (not sure if it's in hub or switch mode) which is hooked up to 2 more computers. I access my server quite often and I want to be able to transfer files to and fro as if I'm accessing the file locally. The server is only a 10 feet away from the workstation so there isn't really an excuse for this not to be possible. I've got GIGe in my workstation and the server so I'm pretty much set.
 
apples, whaaa? Last GIGe switch I found was around $225 how is this possible? I know this sounds funny but maybe I need an ablbiet more expensive one?
 
If you can wait a while, one of my clients ordered one. I can set up some qcheck tests for dropped packets, speed, and the like. I don't expect blazing speed out of the upgrade, the disk systems are not up to it.

Well the point of gige is not to fully utilize the bandwidth but actually to eliminate any bottlenecks there would be with 100Mb ethernet. So in actuality it's perfectly fine to run it with slower drives because then you're accessing it at the same speed as if you were there locally , right....?

I would like that info if it's not too much trouble!
 
SMC 8505T/8508T. I've been told their newer versions are the same electronics more cheaply packaged.

Jumbo frames are a very good thing. I would urge caution about jumbo frame claims, some products claim it but that claim is false.

Saw it, still not what I'm looking for cause I need a switch. BUmp
 
I have not forgotten, but the business owner ordered a new computer and is waiting to set up the new switch and NICs.
 
the normal MTU or frame size is 1500.
by increasing the frame size to 9000, you can transfer data faster. Gigabit networks really only move data at gigabit speeds when jumbo frames are used.
 
A possible "problem" with jumbo packets, is that if your only doing simple network connection stuff, you can actually see slower performance because those jumbo packets take longer to fill up and be sent on their way. If you are always transfering large amounts of data it's not an issue.

Either way you will see marked increases in transfering big files.
 
Another thing is that jumbo frames only works when all your equipment supports it - most likely if you're using a standard off the shelf home grade router (such as a Linksys WRT54G or Netgear WGR614) it won't work if you uplink your router to your switch because you'd be trying to force 9000 byte packets where 1500 byte packets would only be accepted.

Even running with the standard MTU rate of 1500 byte packets, the increased bandwidth of gigabit helps.

Damn, where did you hear abou this? Would the way to counterract this issue would be hooking up the router to a computer, and then have the computer output to the network? Only reason I use the router's DHCP server is because it has WIFI.

not true whatsoever.

the frame size is just a maxium, you don't send a 1500 byte frame for a 64 byte packet.

larger frame sizes do nothing but increase throughput give there isn't a CRC or frame error. On a modern LAN there are zero frame errors. none. which means that the bigger the frame size the better.

It was one of the main reason why FDDI was so blazingly faster than 100 Base-t. Frame size.
 
OK, so when looking for a new gigabit switch, I would want to get one that...

supports Jumbo Frames,

doesn't heat up as much,

and Managed ???

please advise...

If you have to ask, you probably don't need or won't use the managed features.
Unless you want to set up vlans, monitor traffic between nodes on you LAN, and lock down your network to specific MAC addresses, you won't need an L2 managed switch.

You need to go with an L3 managed switch to do any serious traffic shaping, and those are bigger $bucks$ yet.

Thought about getting this one. Cheaper for a brand name and $41.99 after rebate.

I have one of those. It works fine. I paid more 🙁.

Jumbo frames is great in theory but a pain in practice -- every vendor seems to have a different idea of what to do on this issue. 9K, 8K, 4.5K, 9K+14, I may be making up some of these numbers, but from what I've seen, the vendors are too. Point is, unless everything you have connected handles the same jumbo frame size, then you're going to have connection problems, and it's very easy to get NIC's, etc. that don't support common jumbo frame sizes.

E.g One NForce3 MB on hand supports 4.5K and 9K JF's. Nice -- would work fine with the switch (max 9K).

Another NForce3 MB (with a crappy gigabit implementation that goes through PCI) has jumbo frame support for 4088 and 9014. 9014's close enough to 9000 to work, right? Of course it is. Of course it is..

Another PCI adapter Has jumbo frames "enabled" and "diabled". Of course, the "enabled" must be the right size! Read my mind!

Another NForce 6150 MB doesn't have any jumbo frame options. Doh! But surely it'll work without me changing settings. Surely of course.

So, do I give up with jumbo frames for now?

You betcha.
