Re: tulip 100mps card; need advice
George, thanks for advices, The need for such setup was due to the estimated bandwith of overall network transaction of about 0.5Gps. Thus, using CISCO or any other non-PC based solution we need to establish high speed interface between this switcher and some proxy server. The idea is that attaching network interface directly to PC would allow us to solve this task. Is it sounds stupid?

The trouble with going into 10MB mode might not be the network card, many hubs do not auto-negotiate properly. Just force it in the driver at boot. Do you mean linux network driver or card's SETUP utility? I have noticed that hub was able to detect 100mps up to linux loading stage :( Well, looks like money is no object here. Hhmmm :) not quite right, unfortunatly ... Get three of the quad adaptec tulip cards, thats $500-$600 each and gives you 12 ethernet ports on three Are they supported in linux kernel? PCI slots. Make sure those boards will fit ... they are LONG. If you really want to get fancy, you can get a dual-PCI bus machine and put your network on one PCI bus and your disk on the other. Your bottleneck is going to be the PCI bus, you are probably better off getting something like a Cisco 2900 or 3000 series switch rather than trying to do this with a PC. Then we should connect this switch to the server at ~500mps. Is there any standard solution? May be fiber optic? CPU should be SMP Alpha processors. SCSI disk. You are probably in the $10-$15K range for a good system if I am reading this correctly. Eugene Sevinian CRD, YerPhI, 375036, Armenia URL: http://crdlx5.yerphi.am/ Phone: 374-2-344873

George, thanks for info, I'll think about it. Eugene. On Sun, 23 May 1999, George Bonser wrote: Why not use gigabit ethernet? There are a few cards that are supported under Linux. See http://cesdis.gsfc.nasa.gov/linux/drivers/index.html#gigabit for more details.

Hi, tulip.c:v0.89H 5/23/98 [EMAIL PROTECTED] eth0: Digital DS21140 Tulip at 0x6100, 00 c0 f0 17 16 0d, IRQ 11. eth0: EEPROM default media type Autosense. eth0: Index #0 - Media MII (#11) described by a 21140 MII PHY (1) block. eth0: MII transceiver found at MDIO address 1, config 3000 status 7829. eth0: Advertising 01e1 on PHY 1, previously advertising 01e1. Works fine at 100MB on an autosensing 10/100 ProCurve hub. The load is non-existant to moderate, though, but I have heard good things about this card from other people. manoj -- I believe that Ronald Reagan will someday make this country what it once was... an arctic wilderness.

tulip 100mps card; need advice
Hi ppl, today I had a problems with DEC21143 tulip cards. The problem was that card goes into 10mps mode just after linux loading. It seems that there are problems with tulip drivers. Tommorow I will try to recompile the kernel defining default media type 100baseTx. Probably this will help somehow. HOwever I would like to know is there any any 100mps cards which are working reliable at heaivy load. The main goal is to setup a network with star topology, i.e. one central box with 6-7 100mps channels attached to it as well 4-5 10mps ones. Any suggesions concerning hardware components for this central box? How much ROM, which CPU and motherboard I should look for?

Newer kernels seem happy.
