HP ML 350 Raid 641 controller speed issues

I have installed a 641 controller card into an HP ML350 running two 146Gb SCSI in Raid 1 configuration. All of this is working fine. my problem is I have added a 1Gb Belkin NIC PCI into one of the PCI-X slots. There is a total of four PC-X slots on the MB of which I put the Raid 641 Card in the top which is PCi-X 64-100 there is one other that is 64-100 with the other two stipulating other speeds something like 64-133 and 64 - 64 from memory. When I put the NIC in either the 133 or the 64 I was getting a hardware error when i tryed to ping things on the network. It was not untill i put it into the other 64-100 that it worked.

My question is i believe there maybe an effecty on the Raid 641 controller speed becuse the PC-X will slow to match the speed of the older PCI card that I have in the same speed port. i am not sure why it would not work in the otehr PCI-x slots.

Is this the best way of installing the NIC as I need two and or is ther no problem with this configuration.

Thanks

Stephen

I hope not. It depends on how the bus is implemented to the pci-X slots.
Due to the fact that you had no other option than to choose the same speed slots - it may be that there's only one connection to the chipset.

I have to refer to the documentation included with the server - otherwise give HP a call - the helpdesk has access to all the HP documentation - and will be able to give a more accurate answer than we can.

Is your bios updated to the latest version?

And if your problem continues - it may be cheaper to buy an HP ethernet card (pci-X) and put that one in the pci-x slot. I do know that hp-servers are sometimes picky on non-hp hardware
(due to the fact that hp tunes it's hardware to make sure it all works nicely together... hum)

The same goes for e.g. harddisks - you can work with non-hp disks - but if something goes wrong - they'll blame the disks...

Agree with all the above. I work with 30 or so ML and DL ProLiants, and my inclination would be to junk the Belkin NIC. Seems a pity to put a cheap & cheerful NIC in a decent quality server. I've had the best results from Intel gig nics.

As regards it slowing the bus to the lowest common denominator, I think that very unlikely.

Move the 641 to the 64/133 slot as it's a 64/133 card. Admittedly HP's default location is slot 3 but that shares the bus with slot 4. the 133 and 66MHz busses are seperate. Note that moving the card may renumber the bus - I can't remember if it's a PCI bridge - but the OS ought to sort that out anyway.

Andy from what you are saying is it not possible that if slot three shares the same bus as slot four then what I have done is likely to have slowed that speed down for the 641 controller. I am sure I have read that some where else. For pease of mind I may just do what you suggest and move it to 64/133 and see how I go..

mixing speeds on the same bus indeed slows down the faster card to the speed of the slower one. www.stayonline.com/lava_2.htm
