6. Disaster Recovery – The Lot  Source hardware  Download Linux from Internet or buy DVDs  Restore servers from external HDD  Copy data from backup server  Away we go!

7. © The Association of Independent Schools of NSW How can it be done? Hardware with VT technology and plenty of RAM Scenario 1 - VMware  Mainstream Linux or Windows  VMware free server  Scenario 2 - XEN  SUSE Linux OES2 with Xen Linux or Windows  VMware VM1VM2VM3VM4 Linux with XEN VM1VM2VM3VM4

8. © The Association of Independent Schools of NSW Installation of VMs  Install your host OS (Domain 0)  Install VMware server for Linux or Windows or use XEN Virtual Machine Manager  Create virtual machine (specify RAM and HDD allocation)  Install OS on VM  Install apps  Clone your VM as many times as you like
