Abstract: Provided are a method, a system, and a computer program product in which a plurality of switches are maintained in a cascaded configuration. A switch relays a switch fabric internal link services (SW-ILS) to generate a pair of exchanges comprising a first exchange and a second exchange at the switch. In response to a termination of the first exchange of the pair of exchanges, the second exchange of the pair of exchanges is terminated.

Abstract: A host port is enabled for security. In response to a determination by the host port that authentication or security association negotiation with a storage port cannot be completed successfully, the host port determines whether an audit mode indicator has been enabled in a login response from the storage port. The host port preserves input/output (I/O) access to the storage port based on determining whether the audit mode indicator has been enabled in the login response from the storage port.

Abstract: A storage port is enabled for security. The storage port performs Input/Output (I/O) in plaintext on a path between the storage port and a host port, in response to determining that an audit mode indicator has been enabled to allow I/O even if authentication or security association negotiation between the storage port and the host port cannot be completed successfully. Concurrently with performing of I/O in plaintext on the path, the storage port enables encryption of data for I/O on the path.

Abstract: Provided are a computer program product, system and method embodiments for secure communication between an initiator and a responder over a network. The initiator sends a security association initialization message to the responder to establish a security association including key material used to generate a key for the security association. In response to receiving a security association initialization response to accept the security association, the initiator sends an authentication message to the responder to establish authentication between the responder and the initiator. In response to receiving an authentication message response to the authentication message, the initiator is programmed with the security association. An authentication done message is received from the responder after receiving the authentication message response. The initiator activates the security association to use the key to secure communication between the responder and initiator in response to receiving the authentication done message.

Abstract: In one aspect of the present description, safe data commit scan operations of individual data storage systems of a distributed data storage system may be synchronized to reduce the occurrence of reductions in input/output (I/O) response times. In one embodiment, a set of safe data commit scan operations of the individual data storage systems of a distributed data storage system are synchronously timed to substantially overlap in time within a single synchronized safe data commit scan set interval to reduce or eliminate the occurrences of reductions in input/output response times outside the synchronized safe data commit scan set interval. Other features and aspects may be realized, depending upon the particular application.

Abstract: A method comprising: measuring in a first length measurement, a length of a first communication link 214a of a storage area network (80, fig 1A), wherein the first length measurement, length A, is a function of a first minimum command response time over the first communication link 214a; obtaining a current data units per second link speed of the first communication link 214a; calculating a first target resource allocation (e.g. buffer credits) for a first port at a first end of the first communication, and for a second port at a second end of the first communication link as a function of the link speed of the first communication link and the first length measurement for the first communication link 214a; and configuring a resource allocation (e.g. buffer credits) for the first and second ports for the first communication link in accordance with the calculated first target resource allocation.

Abstract: Provided are a computer program product, system and method embodiments for secure communication between an initiator and a responder over a network. The responder receives, from the initiator, a security association initialization message to establish a security association with the responder including key material used to generate a key for the security association. The responder receives an authentication message from the initiator to program the responder to establish authentication between the responder and the initiator after establishing the security association. The responder sends an authentication message response to the initiator to establish authentication with the responder in response to the authentication message. The responder sends an authentication done message to the initiator after sending the authentication message response to cause the initiator to activate using the security association and the key to encrypt and decrypt communication between the responder and initiator.
