Network Connectivity

[BillDHS]

This is not specific to Teradata, but I have found very knowledgable in these forums.

I have been informed by our network team that the WAN between our Teradata Unix servers and our client site is 100mb full duplex ethernet. We have a switch in front of the servers that has a 10/100mb selection for the line, but the ports that connect the 4 NODES are all 10mb.

Questions: would changing the line switch from 10 to 100 mb improve transmission between the server and client, or do the 10mb ports limit that possibility?

Getting further into the NODES, our 4800 NCR boxes have 10BaseT ethernet swithches internally that make me believe that the bynet is running at 10mb. Would this create a limit on the WAN connectivity?

Bill,
For what its worth...

A couple of years ago, a dedicated network was defined to for a data feed from UNIX to Teradata as there was a concern that the "standard" network wouldn't be able to cope.

Due to general incompetence, we later discovered it wasn't actually being used and the traffic was going via the "standard" network with no impact!

Also, if you consider that improving the efficiency of the load / extract process has more impact on overall process times, then you should be able to see that worrying about network performance is secondary.

Roger...

10MB is quite slow nowadays, so you'll probably have to check if your network is running at 100%. If it is you'll have to replace the network cards with faster ones...

The Bynet hardware is separate from your ethernet and (depending on the Bynet release) runs with 20/40/60 MBYTE full duplex bandwith from node to node...
