    Abstract: The invention relates to a method and system for managing virtual network ports on a physical server (10) to provide a virtual server (20) access to a group of storage resources (110) through a network (100) and comprises the steps: generating a storage access group (SAG) (60) representing a group of storage resources (110); executing a hypervisor (14) on the physical server (10); generating a virtual server (20) on said hypervisor (14); for the virtual server (20) activating access to said network (100). A management console (70) creates and manages the storage access group (60) providing access to the group of storage resources (110) for the virtual server (20) the physical servers (10, 12). The management console comprises a virtual server management facility (72) and a SAG facility (74). The virtual server management facility (72) manages virtual server definitions and activates, deactivates, migrates virtual servers (20, 22). The SAG facility (74) provides management of virtual network port descriptions (60), administration of network port names (WWPN1, WWPN2) and creates, activates and deactivates virtual network ports (40). The SAG represents a group of storage resources, virtual servers requiring access to the storage resources and network ports required to access the storage resources.

    Abstract: Information units (UI's) are aligned in a block boundary format. Block protection trailer data is added to each one of the UI's. In a data storage and transmission system information units of variable-length data records such as extended count key data (ECKD) may be stored and transferred according to a fixed-length block protocol such as the T10/SCSI standard. Protection data such as cyclic redundancy check (CRC) hash is added to the end of each block. Padding data may be added to the variable length data when forming the fixed-length blocks. The fixed-length blocks may subsequently be re-assembled into ECKD if required.

    Abstract: The present invention relates to a method, a computer program product and a system for managing virtual instances of a physical port attached to a network. The method is based on the Fiber Channel N_Port virtualization for a physical Fiber Channel N_Port. Multiple virtual Fiber Channel adapters share a single physical N_Port among multiple operating system instances. The invention discloses means for the automatic and persistent generation and administration of unique Worldwide Port Names needed for the N_Port virtualization.
