Abstract: A method according to one embodiment includes receiving a request to perform a backup of data associated with an application running on multiple servers; calculating a time value based on communications with the servers, the time value calculation including at least one of a latency of at least one of the communications, and a difference between a reference time clock value and a time clock value of at least one of the servers; and communicating with I/O Handlers on the servers for initiating a coordinated backup operation on the data at about a same start time. Additional systems, methods, and computer program products are also disclosed.

Abstract: A network system supports multiple network communication protocols. An Ethernet component gateway in a Fibre Channel over Ethernet (FCoE) initiator system converts FCoE data packets from host devices to Fibre Channel over Internet Protocol (FCIP) data packets for transmission to a Storage Area Network (SAN) target system. The SAN target system may include a target Fibre Channel (FC) storage device and a SAN component gateway. The SAN component gateway converts FCIP data packets to SAN data packets for use by the target FC storage device. The SAN data packets may be either FC protocol data packets or FCoE protocol data packets. The SAN target system may provide for discovery of target FC storage device adapter information.

Abstract: Techniques for adjusting the frequency of data backups and initiating event-driven backups in a storage system are disclosed herein. In one embodiment, a self-adjusting backup frequency, known as a "Change Rate Objective," is defined to conduct or delay backups for one or more volumes in the storage system on the basis of an associated policy value. The Change Rate Objective may be tied to one or more business or data activity events, such as the amount and type of data changes since a last backup. The storage system may also be tailored to conduct or delay full or incremental backups on the basis of a Change Rate Objective that measures whether a full or incremental or differential backup is more appropriate. Various data or system failures, or data or business events may also be used to adjust the retention periods of continuous data protection (CDP) data and delay a rollup of CDP data.

Abstract: An apparatus, system, and method are disclosed for dynamically determining a set of Storage Area Network (SAN) components for performance monitoring. The computer program product monitors SAN components of a predefined set of SAN components according to a monitor data structure associated with each SAN component. At least one attribute of the set of SAN components is changed in response to a threshold violation by a SAN component in the set. The SAN components of the changed set are monitored according to the monitor data structure for each SAN component within the changed set as part of a monitoring feedback loop.
