If using SQL Server 2005, the new database mirroring (aka "real-time log shipping") is an excellent solution if you would rather put your $$$ into SQL Server licenses (enterprise edition required) and hardware instead of a 3rd party app.
An advantage of using Microsoft Database Mirroring is that you can remain on a 100% Microsoft supported solution. Assuming a clustered/mission-critical installation would want to insure they have access to PSS (Microsoft product support) for any critical situations, this could be a decisive factor over choosing a 3rd party generic clustering or C/SFS (clustered/storage file system) solution. I'd be curious to hear if Sandy or anyone has compared db mirroring to double-take and other solutions that made sense before this feature was available but may be less desirable now. ---- Robert E.

Unfortunately, I almost always find it easier to justify clustering solutions for my clients *after* they haven't heeded an initial clustering suggestion and have had outages and/or data loss (or if I get them as I clients after such an incident). We use Double-Take as a pseudo-standard, as it has broad industry support and works equally well over the local and wide area. It's going to run you upwards of $3500 for one two-server cluster. Is that "low"? I've demoed and am intrigued by XGForce's eCluster http://www.xgforce.com/news_eCluster.html, which has much more accessible pricing. I plan to purchase it in place of DT for my next rollout and see if I can trust it. But for now, I can't vouch for it, though if you get into it, please let me know. :) --Sandy ------------------------------------ Sanford Whiteman, Chief Technologist Broadleaf Systems, a division of Cypress Integrated Systems, Inc. e-mail: [EMAIL PROTECTED] SpamAssassin plugs into Declude! http://www.imprimia.com/products/software/freeutils/SPAMC32/download/rel ease/ Defuse Dictionary Attacks: Turn Exchange or IMail mailboxes into IMail Aliases! http://www.imprimia.com/products/software/freeutils/exchange2aliases/dow nload/release/ http://www.imprimia.com/products/software/freeutils/ldap2aliases/downloa d/release/ --- This E-mail came from the Declude.JunkMail mailing list.
