Microsoft SCR Question

Microsoft SCR Question

I have two locations, NYC and London, Each site has 25 users with mailboxes, 
I want to setup an Exch 07 ENT SP1 in each Site and have their mailbox 
stores replicated to each other and switch them on if either one of the 
servers failed. In other words, each server will be active but act as the 
standby to the other one. Can this work? thanks

Re: Microsoft SCR Question

- That's the purpose of Standby Continuous Replication (SCR).
- The process of "switching them" is called activation - note, this is not 
clustering per se, so there's no "failover".
- Make sure you make yourself familiar with the activation process - test it 
out in a lab environment.
- Your options are a) RecoverServer (when setting up a new server, can't use 
this on an existing Exchange Server 2007 installation without uninstalling 
Exchange), or b) Database Portability.
- In case of a clustered SCR source (CCR/SCC) and a clustered SCR target (no 
CMS created... ), you can use /RecoverCMS.

Re: Microsoft SCR Question

Thank you very much for the reply, so to be clear: if the london server 
fails, can I failover users to the NYC Server without affecting NYC users?

Cheers,

Re: Microsoft SCR Question

- Again, there's no "failover". That's the term used for High Availability 
clusters - in case of Exchange Server 2007, this would be CCR or SCC 
clusters.
- Failover implies automatic detection of a resource failure, and moving the 
resource (group) to the standby box/node automatically (or with practically 
no effort manually.... ). This is where SCR differs. Since SCR itself isn't 
clustering, there's no "failover".
- However, you can activate a SCR target relatively quickly using the 
methods described in my earlier post, and bring users online on the target 
sever faster than you can restore the unavailable Exchange Server or Store.

Re: Microsoft SCR Question

Oh, there is user impact;  how much depends on what client is in use.  DO 
familiarize yourself with the process.

Re: Microsoft SCR Question

Thank you, One more question: can SCR be setup on an Exchange Server hosting 
multiple Exchange Roles? for example each location server will have these 
roles? Hub Trans, Mailbox, Client Access.

 Thanks

Re: Microsoft SCR Question

Yes, provided the source/target are not clustered.
