This a good place for virtualization. FreeBSD jails are the most efficient form that I'm aware of including XEN. Jails have limitations XEN doesn't however. 2. High load DB's shouldn't be virtualized. 3. EZjails port helps alot! 4. Machine specs would depend on system load, you've given no indication other than apps. 5. You should preplan backup and failover setup. Heartbeat, CARP, rdiff, and other utilities should help here. > > Any feedback would be welcome. > > -Grant > > -- Adam Vande More
