ML370 NIC teaming

Hi guys,

I have a ML370 and just updated the PSP for the machine.

Now I have a lot more choices for my teamed NIC'S (dual gig Ethernet cards).

These are connected to a switch, nothing fancy just a Netgear Gigabit switch.

I am not bothered about fault tolerance, but would like the fastest throughput for my teamed NIC's.

Which setting would you guys suggest for my team.

Thanks

Re: ML370 NIC teaming

Which ML370 do you have? And are you referring to integrated Gigabit NICs?

Re: ML370 NIC teaming



I have ML370G2 and the NIC'S are NC7770's.
I am runing WIN2K Server with all the latest PSP's and windows updates.

Thanks for your help

Re: ML370 NIC teaming

Allan,

You have the option of TLB (Transmit Load Balancing" or SLB (Switch-Assisted Load Balancing). But you'll need to check & see if your switch is SLB-enhanced...if not the option will be TLB. A couple of requirements (aside from the fact you already have matching NC7770 NICs):
- ports on switch must be in the same collision domain
- both NICs must go to same Layer 2 (Broadcast)switch.

Start with this doucument & then let us know if you have any further questions.

Re: ML370 NIC teaming

With respect Terri with TLB the NIC's can go to seperate switches so long as they are in the same broadcast domain (VLAN). A port on a switch is a collision domain and again the NIC's need not be in the same collision domain. Putting the NIC's on seperate switches will need some consideration of redundancy from a spanning tree perspective. It is recommended the switches the NIC's connect to have redundant links into the network core. With a single switch, as Allan has, so long as the ports are in the same LAN (I have no idea if the netgear does VLANs) then TLB will work fine. Both NICs transmit and only one NIC receives.

Regards, Stephen.
