Gigabit With 10/100 Workstations

[mandrake]

so if i was to buy a switch that had a bunch of 10/100 ports and 2 10/100/1000 ports. Would having my gigabit capable gameserver on the gigabit port provide any benefit over having a switch that is ALL 10/100 ports. Or do you only see the gigabit advantage if you're talking to a computer on that second gigabit port (asuming the second computer also has gigabit capable nic).

 

if i had a dollar for every time i just said gigabit...

You're only going to see a benefit on the machines that have gigabit nics. Anything on 10/100 is still going to send/receive at that speed no matter how fast the feed to it is.

[galla2k4eva]

there would be a big bottleneck down from 1000 to 100

oh and you would have 5 dollars by my count

heh, thanks guys. that's what i figured, but i didnt know if two 100mbit connections from two seperate workstations could use 200Mbit of the 1000 available, or if they'd just wait in line.

[ir_cow]

10=1mb/sec

100=10mb/sec

1000=100mb/sec

 

for anyone who didnt know

 

and at 100mb/sec unless your in raid you cant get it that fast, most hdd dont write faster than 50mb/sec

[Scottious]

Correct me if I'm wrong, but isn't

 

10 Mbps = 1.25 MBps

100 Mbps = 12.5 MBps

1000 Mbps = 125 MBps

 

?

yea, if you have a 100Mb/s connection, although you wont hit the full 100, i did manage to hit 80Mb/s. your network will run as fast as the slowest link. i had my main rig w/ gig nic connected to a gig switch which was then connected to my laptop which has 100mb/s. obviously it was limited by my laptop. it ran a 80Mb/s (i watched it) not terribly exciting

[ir_cow]

yes your are right 1000=125 opps, its close anyways. but the laptop to giga going at 80mb/sec doesnt make sense the laptop must be giga too or it be limited to 12mb/sec.

[CNUco2007]

i wish it was gigabit. but its a 10/100mb. and even my desktop said it was recieving at 80mb. it averaged between 50 and 60 though. it only spiked to 80. If its limited to 12mb/s then what would be the point of calling it 100mb/s? are you talking about 12mB/s? there is a big diff between megabytes (MB) and megabits (Mb).

 

*edit* another thought... i measured my download speed at school to be 19Mb/s. so ur number is skewed somehow. now if ur just converting 100Mb/s to 12.5MB/s, then that makes sense, but my numbers are in bits. oh and btw, i only hit 19Mb/s cuz it was like the first day of school and nobody else really had their computer hooked up yet so i had lots of open bandwith haha

[cchalogamer]

Im thinking 90% of people reading this are going wtf too many mb/Mb/mB/mb things floating around then ppl using one where you expect the other lol

 

Well to help clear it up a little for some of them the RATED SPEED of nics etc is in megabits per second but their are 8 bits in a byte so divide that by 8 to get max speed (like Scottious did above)

 

Hope that helps someone.

 

 

Now as for the question I dont think that a switch will let ti "split" the connection in that manner to speed transfer, im pretty sure you'll just get a 100mbps connection split.

[Scottious]

Another thing to watch out for is the speed of the PCI bus. Most network cards (even onboard network cards) are connected to the PCI bus and that runs at 100something MBps I think. So if there's a lot of bandwidth going over the PCI bus then things will be a lot slower, I presume.

 

Just a thought.

[mandrake]

cchalogamer, i think you may be right. My thinking was that if you compare a lan to the internet, a DSL -> dialup trasfer would be limited to dialup speeds, but a dsl -> 2 diff dialup's would not be limited to dialup /2, the dsl line could still throw out dialup x 2 speeds.

 

trying to make a very basic analogy lol
