1Gig Ethernet

Hello Volker.

Can you be a little more specific as to known problems that you are aware
that have been encountered by shops attempting to use 1 Gb Ethernet to replace
Opti. What we are looking at doing this with 2 Application servers 820's each
with 2 GB cards. One for the Opti replacement, other for user logon. At the DB
level 1 BG Ethernet card just for data, 100m for Basis logon to that box.

Now as I see from Doreen response She has this working for 3 years?

Doreen what SAP Release and OS/400 are you on? What kind of traffic load do you
have Light 50 or less concurrent users, Medium around 200, Heavy 400-500>.


Big thanks to JJ, Doreen and Volker for information provided.

Udo

Hi Udo,

I can fully agree with Doreen and JJ.

It is no problem at all to divert the traffic. It is just a bit configuration.
But, as opticonnect is slightly faster than GB Ethernet, I wouldn't invest money
itno this. If you really want to go this way, you should ask IBM for the new GB
Ethernet Card, that requires V5R2. This one is supposed to have no longer the
known bottleneck of the old one. But, I definetely wouldn't
do it on V5R1.

Before you go to V5R2, you should ask IBM if all performance problems for your
environment are fixed.

Regards

Volker

Hello Groupies.

Layout 3 Tier V5R1M0 840 DB, 820 App servers. 4.6c EBCDIC.

Plans call for here at LF. To get rid of opticonnect and use 1 Gig Ethernet
card to replace, to be precise 2 1GB cards in each App server ( we have 2 app
servers). The part that I'm not clear on and maybe some one out there in the
wide, wide world has done this or can shed some light on this.

Here it comes. How, or can I select which card is used for normal
communication, and assign the second one as a replacement for the Opticonnect
path.

Hope that this makes sense.

Thanks Udo
