RE: Exchange Failover Product..
Sorry I am chiming in late on this but. We use XOSoft's (now CA) WANSyncHA and I love it. My replica/failover Exchange box is about 30 miles from my main office. The TLS circuit between the two is 10MB. I have an Is Alive ping between the two set for 10 minutes (allowing for reboots after patches/hot fixes and even the occasional drop of the TLS circuit as well. If the replica doesn't get a response from the MASTER Exchange box for a period of more than 10 minutes it switches DNS records (internally in my organization) and redirects all the email client to itself. Seamless and worry free. My users have never been aware of a failover.

RE: Exchange Failover Product.. Stu's perspective
There are some essential differences between SCR and Double-Take: Standby Continuous Replication uses asynchronous log shipping and reply to create a backup standby database on a target Exchange server. Unlike CCR, which relies on clustering and provides high availability, SCR sends data from a standalone or clustered Exchange server to a standalone Exchange server and provides no failover capabilities. SCR shares some of the same limitations as LCR and CCR and introduces some new limitations. Some items to consider about SCR: SCR provides no failover. SCR is designed to create a standby database that matches the source database, similar to LCR but with the database residing on a separate server. To provide high availability and DR, Microsoft recommends combining CCR and SCR. SCR recovery is complex. The SCR recovery process is a series of manual steps executed on the command line to bring the target database online. This is a complex process compared to the ease-of-use with DoubleTakeAM's automatic or push-button failover and failback capabilities. SCR is not real-time protection of Exchange data. SCR works by shipping log files locally and applying them to a second copy of the Exchange database. It is not real-time replication. SCR replication is delayed. There is an enforced delay of 50 log files with SCR replication. This means that 50 log files must be replayed into the target datastore before the target server can be brought online for recovery. You must use a single database per storage group. When a storage group has been enabled for SCR, it can only contain a single database. This prevents you from scaling up by having multiple databases per storage group. Double-Take does not have this limitation.

RE: Exchange Failover Product..
I've been anti-cluster for a very long time. the only good cluster is a single node -Ed | I have always agreed with him Lately I have been building Clusters and putting VM's on them; I am starting to feel that that is the best way to do it. Your Cluster becomes a hardware pool with redundancy that you can place virtual machines on. You can optimize the hardware pool resource allocation to the virtuals on the fly; adding and removing ram and what not as needed. It makes it very simple to add more hardware to your servers, you just add another cluster node and move the VM to the new hardware, takes minutes in the users eyes. No need to migrate or fiddle with server names and IP address and crap like we have to do on dedicated hardware. ~2000$ for an 8 proc server with 16GB or ram, and ~2000$ for Windows server 2008 enterprise ( comes with 4 VM server cals, for 6k you can run datacenter and have unlimited VM's) to add a node that can support 1-10+ VM's depending on what you need. Well you have to storage in there. I just build a 4TB NAS running open filer ( 8 x 1tb drives in raid 0+1 for I/O) for like 3500$ or something. I am starting to like clusters, just not clusters but I still don't like clustered Exchange ~Kevinm WLKMMAS powered by 3Sharphttp://www.3sharp.com/, Always WLKMMAShttp://www.wlkmmas.org/ What is your Zombie Plan?

RE: Exchange Failover Product..
Clusters allow a well-managed server farm to go from 99.9% availability to 99.99% availability. Emphasis on well-managed. Those are, quite frankly, few and far between. In most shops that I've seen, clusters actually reduce availability. These days, you can install Exchange, configure it a little bit, set up your backups, and it'll just hum along for you for months and months without requiring you to touch it. Run a patch install at 3am on Sunday morning once a month, and you're done. If you buy good hardware for the server - you'll probably not have to touch it except when a disk needs replacing. And of course, you have SMART/SCSI monitoring, so you know when that happens, you pick up a phone and order a disk, it's hot-swappable and auto-rebuild. Or you have it in inventory because e-mail is a critical service. You're done. No frickin' way you get off that easy with a cluster. It requires a LOT more care and feeding. In certain (very rare) circumstances, I can believe that that expert care and feeding is worth 0.09% increased availability. But honestly, I don't think I've EVER seen one. Regards, Michael B.

Re: Exchange Failover Product..
My current gig has a cluster and I am in process of planning to make it cluster-no-more. I hate managing the fscker... Totally not worth it, but Dell suckered the company into thinking they needed it... On Tue, May 13, 2008 at 2:50 PM, Michael B.
