    Abstract: Techniques for determining service levels may include receiving an I/O operation at a target port of a data storage system, where the I/O operation is sent from an initiator port of a host and directed to a storage object in a first storage group. The initiator port may be included in a first initiator group and the target port may be included in a first port group.

  • Patent number: 11068581
    Abstract: Techniques for establishing connectivity may include receiving a first login command from an initiator port at a target port; and determining whether the first login command includes valid login authentication information for the initiator port that sent the first login command, and whether the initiator port identifier of the initiator port that sent the first login command includes a key. If the first login command does not include valid login authentication information and the initiator port identifier includes the key, first processing may be performed including: recording first information about the first login command in a registration table; and rejecting the first login command. A second login command may be received from the initiator port at the target port. If the second login command includes valid login authentication information for the initiator port, the second login command may be successfully processed to log the initiator port into the target port.
