Add some extra web front ends and load balance them (hardware or Windows NLB)
You can put the Query role on each WFE The App tier can also be balanced except the Index role - that can only run on a single box. You can use clustering for SQL. If you mirror the data elsewhere, you'll need to run something using stsadm.exe to point the farm to the new SQL Server Cheers Ken From: Kelsay, Mark [mailto:[EMAIL PROTECTED] Sent: Wednesday, 24 September 2008 1:33 AM To: NT System Admin Issues Subject: RE: High availability Not my choice on signatures. Damn insurance governance here in the UK. I had just started to read about database mirroring with SQL2005. Which looks good for my needs. I guess I could add another box to the farm and setup it up as a web/app box. From: Michael B. Smith [mailto:[EMAIL PROTECTED] Sent: 23 September 2008 16:03 To: NT System Admin Issues Subject: RE: High availability Could you possibly make you signature just a little longer? :) And I get crap about mine!!! I don't think that with current technology I would do either of what you've suggested. I would use mirroring for my database HA and I would use either hardware or software load-balancing for the web/app server (with stickiness - IP affinity - enabled). Regards, Michael B.

I used Double-take several years ago but was wondering if there were any other products that some of you would recommend? We are looking to cluster the SQL box in our farm but would like to have an active-passive setup for the web/app server.
