Re: Multiple Gateways to avoid single point of failure?

[Kathy J. Mikich]

If you had two idomains for exchange users then it is possible to have two Exchange gateways.  With out that all Exchange users would be in the same post office and domain and all the groupwise domains would know that they had to send mail to this external po via the gateway.   I cant see a way to make it have two gateways that would handle mail if the other was not functioning. 

 

I can however see you route your mail out the smtp gateways to each other and that might give you some peace since it would be the same as all Internet bound mail and the failure points it has.

 

To route mail out the gwia with the Exchange gateway installed you simply have to insure there is not an idomain for the exchange system under tools / internet addressing and you also need to set "a" Internet address over ride on the externals domain from with in consoleone.  Any over ride on the external will cause the mail to go out the GWIA.

 

dir sycn and busy search will still go thru the gateway.

Hi,
I'm a relative newbie to the GW-Exhange but have reasonable experience
in GroupWise 7 and MS Exchange.

I'm workiong on a design to link two mid-size organisations (of around
1200 mailboxes each). The combined organisation hasn't yet decided which
way they're going to leap - GroupWise or Exchange.

In the meantime, my design has to try to avoid a single point of failure
- of which the GroupWise 7 Gateway for Exchange is a very good target.

Does anyone know if I can have two gateways in the mix - perhaps one
"live" and the other in "hot-standby"; or even both in "live" mode.

Your comments and thoughts would be appreciated.
