The inactive/evicted model is particularly effective though.

I would say that clustering is falling out of favor, not CCR specifically. Clustering adds a lot of cost and a fair bit of maintenance complexity to get a very small up-time improvement. And if your operations folks aren't good - it can lead to worse up-time instead of improved up-time. I'm of the opinion (and it is just that - my opinion) that if you buy good hardware to start with (redundant fans, redundant power supplies, name-brand memory, etc.), that clustering isn't worth the cost. I haven't played with Windows 2008 dispersed clusters yet. They may make it easier and more worthwhile. I dunno yet. Regards, Michael B.

Ive had a CCR implementation with 10 storage groups and about 200gb of data running on RTM code since last August with no issues. Works great, smooth and reliable failover ..so far. Why is CCR falling out of favor ? I can see where it adds some complexity in setup but the MNS style clustering makes that a lot easier. It does make patching more difficult .. I still need to do SP1 when I have a spare minute. Pete Howard | Systems Engineer MCSE 3.51-2003 | ESX VCP * EMail: [EMAIL PROTECTED] ----- Original Message ---- From: Michael B.

The first two lines are about a particular client using CCR, sorry. The last line is a generic statement. I wasn't clear. Regards, Michael B.

So you guys aren't using CCR or SCC Michael? From: Michael B.

Geodispersion is coming, using Windows Server 2008. Backup is LCR to cheap disk. I'm seeing more folks moving away from clustering with LCR and SCR. Good riddance, in my opinion. Regards, Michael B.

Curious to know what folks have seen in the field when using CCR. How many users, how large are your databases, any issues you've encountered. Any geo-dispersed clusters, special quorum configs, and how are you backing all of it up? thanks! -alex ~ Ninja Email Security with Cloudmark Spam Engine Gets Image Spam ~ ~ http://www.sunbeltsoftware.com/Ninja ~
