And that the Intel card supports multiple ip stacks. I.e you can use trunks with clusters,use redundant network setups etc

My understanding was that the Intel cards outperformed the Alteon cards and that was the reason for the switch by NetApp.

I can't speak about Sybase, but I'm running Oracle across Gigabit. In terms of the pipes size, I've never come close to 100MB/s. My F740 filers seem to top out at around 20MB/s. I "think" it's helping, in that there is less latency on the connection. But the problem I see mostly is high biod utilization under high i/o load (I'm running across nfs). Expecially things like creating tablespaces. On a 4 processor system (rs/6k-f50) I've seen biod run as high as 30% of the system. My disappointment is that NetApp doesn't supported gigabit jumbo packets, even though they announced they would support them quite a while ago when they first announced support for gigabit. I notice that those announcement letters are no longer available on their web site. A search for "jumbo" turns up nothing, where it used to turn up an announcement letter for Alteon nics and jumbo packets. Every db block (4k) thats read from the db

and you may also notice that the Alteon cards don't seem to be shipping

default anymore. the last few clusters i've had come in I had to specifically request the Alteon cards since we weren't ready to leave 5.3.2R1 just quite yet.
