Hello All,

First off, I haven't purchased any server yet.  What I would like to do is have two MS TYPE Server (preferably  SBS 2008 or 11) and have them replicate each other, including applications which run on the server.   So if one server goes down then the second one takes over.  .

What OS do you recommend?



What are the benefits of doing this on a virtual, other than cost of hardware?

Forgive me if you know this already know this, but the more redundant a solution the more expensive it is. No level of significant redundancy will be cheap.

You cannot fully mirror two servers without expensive third party software. You can perform limited mirroring of things - for example, you could implement DFS-R for file server replication.  And a second DC would provide DNS and AD replication and effectively mirror things.  Exchange, SQL - these are VERY expensive to mirror.  IF you intend to use these services and mirror them, you will spend at least 5 figures in hardware, software, and implementation.

Tools that can mirror entire servers include software products like DoubleTake and Neverfail and hardware devices more commonly known as BDRs (Backup and Disaster REcovery devices).  Note: when purchasing Windows licenses, ESPECIALLY to keep your options open, you DO NOT want to buy OEM licenses - that is, licenses that are sold with and pre-installed on the server.  Such licenses cannot be moved and are thus incompatible with BDR solutions and mirroring software.  Buy a volume license - the cost is only slightly more (and in fact, may be less) and provide this desired flexibility.
