2 results about "World Wide Name" patented technology

An identifier, such as a worldwide name, corresponding to a host computing device, or corresponding to a host bus adapter corresponding to the host computing device, may be transmitted to a storage array to configure the storage array to be accessed by the host computing device. The host may request a token from the array. The host may embed the token into a token block of a command message that is transmitted to the storage array requesting access to the array. Before performing an action corresponding to the command message, the storage array may verify that the token is a valid token and thus that the host computing device that transmitted the command message is a host computing device that has been authorized to access the storage array. If the storage array determines that the token is valid the storage array may perform an action corresponding to the command message.

One or more aspects of the present disclosure relate to verifying port connectivity in storage environments. A storage array obtains Fabric Device Management Interface (FDMI) metadata from a switch containing information about World Wide Names (WWNs) associated with host bus adapter (HBA) ports. The storage array analyzes the metadata to determine multiple WWNs associated with the same physical HBA port and examines masking information to identify array ports masked to those WWNs. The system detects connectivity configuration issues, including single points of failure where redundant connectivity appears to exist, non-uniform masking patterns across virtual WWNs sharing a physical port, and fan-in conditions where excessive array port connections create performance bottlenecks. Upon detecting these issues, the system initiates corrective actions and provides warnings to prevent uneven input / output (IO) load distribution and improve storage network reliability.
