300Mb Lan

[Guest_imported]

Hi,
I have a query.
Would it be possible say to have three 100base NIC in one machine connected to a hub and then connected to another machine with three NIC cards.
The objective would be to send the same data down the NICs at the same time.
So in theory have a transfer speed of 300Mb.

For example i'm tring to send a 6gb single file to another system, but it will take hours on a single NIC.
How would I send that file using all three of the NIC at the same time.
And receive it on the other system at the 300Mb speed.
I hope that makes sense

thx

You'd need a switch that can cope with that much throughput. Is it possible to direct connect them instad of using the hub? Are they near enough physically?

If so:

Put one NIC from each server on the LAN. Direct connect the other two NICs to each other bypassing the LAN with IP addresses in a private range that no one else needs know. So long as they talk to each other then you get 100Mb/s LAN and 300Mb/s server to server asuuming everything works together.

This is a common practice. It's called NIC teaming. You can have multiple NICS connected in one server. Third party software is needed in Windows NT 4.0 to accomplish this. A good example is Compaq NIC Teaming. With Compaq teaming there are three ways to perform teaming:

1) Fault Tolerant Teaming: This is when you have two nic cards installed in the server. One nic is "live" at all times. The other nic is a standby nic...in case the first one fails. You can connect each NIC to a different switch. This way if a switch goes down, the primary NIC will stop and the secondary nic, connected to a different switch, will take over.

2) Load Balancing teaming- (This is still fault tolerant) This uses one or more NICS installed in the server. It combines the bandwidth of the NICS. The software enables you to team all of the NICS together under ONE IP adress. You can use Load Balancing teaming regardless of what you are connecting to.

3) Cisco Fast EtherChannel Teaming: This type is similar to Load Balancing teaming; however, you will get more bandwith and throughput using this method. This method requires that you are connected to a switch that uses Cisco technology.

Ipmetrics makes software that will bond multiple nics as one interface. This allows for fault tolerance as well as improved bandwith. You also will net a fast ethernet switch for with enough ports to handle the 6 server nics as well as any workstations.
