Abstract
A computer cluster includes: a first compartment, further including a plurality of first physical nodes configured to provide first resources for a first infrastructural virtual instance and second resources for guest virtual instances; and a second compartment, further including a plurality of second physical nodes configured to provide third resources for a second infrastructural virtual instance and fourth resources for guest virtual instances. Each of the plurality of physical nodes further includes a mass storage device, the mass storage device further including: a partition provided for booting the physical node; a partition as part of resources assigned to an infrastructural virtual instance; and a partition as part of other resources. The first infrastructural virtual instance and the second infrastructural virtual instance are configured for monitoring each other.

19. A method for providing disaster recovery functionality for a computer cluster, the method comprising:
-
operating at least one of a first infrastructural virtual instance and a second infrastructural virtual instance, wherein the first infrastructural virtual instance corresponds to a first compartment of the computer cluster and the second infrastructural virtual instance corresponds to a second compartment of the computer cluster; and when both the first infrastructural virtual instance and the second infrastructural virtual instance are operational; operating one of the first infrastructural virtual instance and the second infrastructural virtual instance as a master virtual instance; and operating the other of the first infrastructural virtual instance and the second infrastructural virtual instance as a slave virtual instance; and if the master virtual instance fails, operating the slave virtual instance as the master virtual instance; when only one of the first infrastructural virtual instance and the second infrastructural instance is operational; operating the operational infrastructural virtual instance as a master virtual instance; activating the other infrastructural virtual instance; and operating the other infrastructural virtual instance as a slave virtual instance. - View Dependent Claims (20)
