Intel (e1000) vs Broadcom (tg3) NICs for Oracle RAC

Alex,
What OS are you talking about?
If Windows, be aware that some Broadcom chipsets have problems with the
TCP Offload Chimney that is enabled by default in the Scalable
Networking Pack (SNP) that is part of Windows 2003(R2) SP2.

Eg see http://support.microsoft.com/kb/942861

This can lead to the TCP keepalivetime function not working and thus
orphan sessions building up in the database - eg when clients reboot or
lose network connectivity.
I'll be posting more on this in a separate posting.

HTH,
Bruce Reardon

Anyone has any insights on which NIC's are more reliable?

We have clients using both and they work quite nice but I'm doing one
install and the machines have abundance of NIC's so I can choose. I
don't have any preference ...

Cheers,
Alex
