This however does not help you one whit if the MAINTENANCE required is Exchange maintenance.

But, clustering will help you if (like your original request) you desire redundancy for the server, the Windows OS, and all processes and services running on that server. If you have problems with services stopping, Dr. Watson or Blue Screens or even intermittent hardware failures, the passive server will fail over and start your "virtual" Exchange server on the other hardware. We don't have many problems at all with Exchange or hardware, but where clustering is really advantageous is when you have to do MAINTENANCE - such as applying security hotfixes, service packs, or if you're having problems with a stuck service that requires a reboot. Trigger the servers to failover and you've got the machine to yourself. Failovers typically take about 30 seconds. During that time Outlook will appear to hang, but then (I always recommend Outlook 2002) it will reconnect to the other server and continue normally. The cluster manager will also attempt to start services when they've gone down before they failover - if that's what you want it to do. So, it's pretty flexible and does a lot for uptime and customer satisfaction.

You don't need clustering if you use good quality hardware and proactive monitoring.

It's not seamless, and in most cases not necessary anyway. -----Original Message----- From: Soysal, Serdar [mailto:[EMAIL PROTECTED]] Sent: Wednesday, May 08, 2002 3:46 PM To: Exchange Discussions Subject: RE: Exchange Redundancy It's still called clustering. Serdar Soysal -----Original Message----- From: Mark Taylor [mailto:[EMAIL PROTECTED]] Sent: Wednesday, May 08, 2002 3:33 AM To: Exchange Discussions Subject: Exchange Redundancy Having just had our sole Exchange server go down, is there a way of having a redundant server (or load balancing) that is an exact replicar (in terms of user mailboxes etc..)? Basically i am after failover redundacy, so that if one server goes down it will not effect users abilities to send and recive mail. - Is this practical? _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED] _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED] _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED] _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED] _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED] _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED]
