    摘要: A method, system and computer program product for migrating at least one switch in a storage area network is disclosed. The migration is done by analysing the I/O traffic to identify patterns in the I/O traffic of the switch; forecasting future I/O workload of the switch based on one or more identified patterns in the I/O traffic, determining appropriate timing for migration based on the identified patterns and administrator inputs; processing the storage area network configuration data to identify the storage network physical and logical access paths to the or each selected switch to create a first connectivity map; generating a second connectivity map based on the first connectivity map and administrator inputs; and migrating the or each switch migration based on the second connectivity map and the appropriate timing. The migration may comprise routing the I/O traffic from the switch to be migrated to the alternate switches in the storage area network. The migration may further comprising transforming zones on the switch to be migrated and deploying the transformed zones to the new switch.

    摘要: A system and method of input/output (I/O) workload analysis of the components in a storage area network (SAN) are disclosed. In one embodiment, I/O workloads of components in the SAN are analyzed by determining host bus adapter (HBA) port to storage port oversubscription ratios as well as HBA port to inter-switch link (ISL) oversubscription ratios. A subset of the components for monitoring based on the HBA port to storage port oversubscription ratios and the HBA port to ISL oversubscription ratios is selected. The subset of the components is continuously monitored and the I/O statistics of the subset of the components are stored. Expected I/O workloads of the subset of the components are forecast based on current I/O workloads associated with the I/O statistics of the subset of the components and respective I/O workload threshold values of the subset of the components.

    摘要: Provided is a magnetic graphite nanoplatelet, and a method of manufacturing nanocomposites by introducing the magnetic nanoplatelets into a composite matrix. Expanded crystalline graphite, in the form of graphite nanoplatelets, is mixed with magnetic particles to adhere the particles to the nanoplatelets. The magnetic graphite nanoplatelets are combined with a composite matrix, typically a polymer, to form a nanocomposite. In the presence of an applied magnetic field, the magnetic graphite nanoplatelets orient and align consistent with the magnetic field to yield a composite having enhance mechanical, electrical and thermal properties
