Hi all.<br><br>First of all, thanks a lot for all the answers. They clarified this subject to me.<br><br>Anyway, since this seems to be a good (AND cheap) solution in many cases, I decided to ask a bit more in detail:<br><br>
While looking for the motherboards for our 8-12 dual-core-nodes cluster, already with the idea of using on-board dual-Gb ethernets on it, we came across the MSI K9N Ultra and bigger ones family. In this family, there is the MSI K9N Platinum (

</a>), which is appearing around here at a really affordable price (a bit more than 2 hundred dollars each here).
<br><br>This motherboard uses the nForce 570 MCP chipset from NVidia, and the dual lan bythe Vitesse VSC8601.<br><br>Here is where our concerns now are held: Basically, is this a good dual Gb lan, good in terms of clustering applications? Has anybody ever used it before, or heard about someone using? Or shall we step back about this specific chip/motherboard?
<br><br>Any help on this subject will be very welcome.<br><br>Thanks a lot,<br><br>Jones<br><br><div><span class="gmail_quote">On 11/14/06, <b class="gmail_sendername">Robin Harker</b> <<a href="mailto:robin@workstationsuk.co.uk" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">

<br>don't even think about not using them. AS far as switches are concerned,<br>ignore all layer 3 devices, as you will never use the functionality and go<br>for a cheap as chips layer 2, (non-blocking) from a manufacturer you have

beowulf@beowulf.org</a><br>Subject: [Beowulf] onboard Gb lan: any opinion, sugestion or impression?<br><br>Hi all.<br><br>Well, I've found some discussions within this list about brands of switches,<br>and some about network card brands also.
<br><br>We came to a question here, in the cluster we are planning: how usefull are<br>the, now so common, onboard gigabit networks (even dual networks) that are<br>shipped in the motherboards? Great, bood, bad or terrible performance?
<br>stability issues? Much concern about it's use for clusters? Is there any<br>example, or benchmark available of different onboard network chips in any<br>(cluster?) application?<br><br>Thanks a lot in advance,<br><br>
Sincerally yours,
