Abstract: A remote management controller is provided for use in conjunction with a managed host computer. The remote management controller exposes a virtual network interface controller, such as a driverless virtual USB network interface controller, to the managed host computer. Through the in-band connection provided by the virtual network interface controller, the remote management controller can send a command to the host operating system or one or more guest operating systems executing in a virtualized environment. If no reply is received to the command, the remote management controller takes corrective action to restore the operation of the host operating system or the non-responsive guest operating systems.

The remote management controller exposes a virtual network interface controller, such as a driverless virtual USB network interface controller, to the managed host computer. Through the in-band connection provided by the virtual network interface controller, the remote management controller can communicate with in-band management applications executing on the managed host computer. The managed host computer can also access services executing on the remote management controller through the in-band communications interface. The remote management controller can also enable communication between the management client computer and in-band management applications executing on the managed host computer. The managed host computer can also access an out-of-band communications network between the remote management device and a management client computer.

Abstract: A method, system, and apparatus for expanding the storage capacity of a data storage system are provided. According to one method, the physical storage devices that store the data and metadata for one or more logical disks are organized into a container. A logical disk segment is created within the container for each logical disk. When storage capacity is added through the addition of logical disks, a new logical disk segment is added to the end of the container for the new logical disk. When storage capacity is added through the addition of capacity to an existing logical disk, a new logical disk segment is added to the end of the container for the new logical disk segment within the logical disk. The devices within a container may be migrated between server computers or between CPUs with their associated mass storage controllers.

Abstract: A method, system, apparatus, and computer-readable medium are provided for dynamically provisioning available space in a data storage system without having to configure partitions at system startup. According to one method, a system table is maintained that includes entries corresponding to provisions within the available physical capacity of a data storage system. A volume table is also maintained that includes entries corresponding to territories within a logical data storage volume. When a data write operation is requested, a determination is made as to whether physical space has been allocated for the territory in the volume that is to be written. If physical space has not yet been allocated, the necessary physical space is allocated for the territory within the logical volume that is to receive the written data by creating a pointer to an available entry in the system table in an entry in the volume table corresponding to the territory to be written.
