摘要： A method for enabling file system tagging by an application includes creating tag associations for the file system by associating a tag with a file object. The association includes allocating a file association structure (FAS) in the storage device, which FAS has attributes including a pointer to a file handle of the file object and a list of names of tags associated with the file object. Associating the tag with a file object also includes allocating a tag structure for each tag in the file system. The tag structure includes a tag name and file associations for the tag. In response to a request for a read directory operation, the method includes retrieving the tag associations to identify the file object, dynamically assembling a directory entry structure that includes a hierarchical view of tags identified from the tag associations and corresponding file object, and returning the directory entry structure to the application.

摘要： A network virtualization layer for an information handling system in which a physical machine coupled to a network is divided into a plurality of logical partitions, each of which has a host system residing thereon. In response to receiving a set command from one of the host systems specifying a data link layer (layer 2) address, the virtualization layer associates the data link layer address with the host system and forwards to the host system data packets specifying the data link layer address as a destination address. Unicast packets are forwarded to the single host system specifying the destination address as an individual MAC address, while multicast packets are forwarded to each host system specifying the destination address as a group MAC address. A host system may also specify a virtual LAN (VLAN) ID, which is used to scope the forwarding of packets to host systems sharing that VLAN ID.

摘要： A system and associated method for handling a system call in a hybrid system. The hybrid system comprises a first computer system and a second computer system coupled to the first computer system at a respective kernel of the respective computer system. A user application of the first computer system requests a kernel service by invoking a system call to a first kernel. The first kernel determines that the system call is remotely executed by a second kernel of the second computer system. The system call and associated parameters are converted to be executable in the second computer system and transferred to the second computer system. The second computer system executes the system call and a result is returned to the first computer system. The result is reversely converted for the first computer system and the user application receives the result.

摘要： A system and associated method for shifting workloads across platform in a hybrid system. A first kernel governing a first platform of the hybrid system starts a process that is executable in a second platform of the hybrid system. The first kernel requests a second kernel governing the second platform to create a duplicate process of the process such that the process is executed in the second platform. The process represents the duplicate process in the first platform without consuming clock cycles of the first platform. During an execution of the duplicate process in the second platform, the first kernel services an I/O request of the duplicate process that is transferred from the second kernel to the first kernel. When the duplicate process is terminated, the process in the first platform is removed first before the duplicate process releases resources.

摘要： A system and associated method for handling a cross-platform system call with a shared page cache in a hybrid system. The hybrid system comprises a first computer system and a second computer system. Each computer system has a respective copy of the shared page cache, and validates an entry in the respective copy of the shared page cache for pages available in the respective computer system. The cross-platform system call is invoked by a first kernel to provide a kernel service to a user application in the first computer system. The cross-platform system call has a parameter referring to raw data in the first computer system. The cross-platform system call is converted to be executed in the second computer system and the raw data is copied to the second computer system only when a page fault for the raw data occurs while executing the cross-platform system call.
