I'm way outta my element on this one.
We have a new solution being setup and surprisingly enough the consultants doing the implementation are asking ME to look into this part. We have 5 sites, WAN infrastructure will be 1.5Mbps T's in a fully meshed MPLS cloud (later this year). Each site houses a Server 2003 R2 x64 Enterprise host for an Oracle based front-end application to SAP. The servers are brand spankin' new HP DL380 G5's.
What they want to do is provide failover for a site from a primary server at the facility to a server at one of the other sites in our organization. The downtime is to be scheduled in order to bring down the Oracle database and do a full offline backup of the server data, (backup software is BAckup Exec 12 with Oracle agents installed).
WAN infrastructure, at the moment, is a mass of branch-office VPN tunnels in a star configuration terminated at the home office on a Nortel Extranet 1510 switch (and yes, that IS damned old). MPLS will be all Cisco hardware and managed by the ISP.
I've read through some of the technet docs for configuring network load balancing and IP load balancing but I'm not sure if I'm in the right ball park, so any advice will be welcomed.
