摘要： A first logical partition in a first processing complex of a server cluster is operated at a first level of a software code. Software code in a second logical partition in the same processing complex is changed to a second level. Processing operations are transferred from the first logical partition in the first processing complex to a third logical partition in a second processing complex of the server cluster. In another aspect, the transferring of processing operations includes quiescing the first logical partition to cause a failover of processing operations from the first logical partition in the first processing complex, to the third logical partition in the second processing complex. In yet another aspect, a failback operation is performed and a first portion of the processing operations are transferred from the third logical partition in the second processing complex, to the second logical partition in the first processing complex. In still another aspect, a second portion of the processing operations may be transferred from the third logical partition in the second processing complex, to the second logical partition in the first processing complex of the server cluster. In one example, the transferring of the second portion of processing operations includes quiescing the third logical partition to cause a failover of processing operations from the third logical partition in the second processing complex, to the second logical partition in the first processing complex. Other embodiments are described and claimed.

摘要： A method for improving the reliability of host data stored on Fibre Channel attached storage subsystems by performing end-to-end data integrity checks. When a read or write operation is initiated, an initial checksum for data in the read/write operation is generated and associated with the data, wherein the association exists through a plurality of layers of software and attached storage subsystems. The initial checksum is passed with the data in the read/write path. When a layer of software in the read/write path receives the initial checksum and data, the layer performs an integrity check of the data, which includes generating another checksum and comparing it to the initial checksum. If the checksums do not match, the read/write operation fails and the error is logged. If the checksums match, the integrity check is repeated through each layer in the read/write path to enable detecting data corruption at the point of source.

摘要： A method and system are provided for managing requests to access data in a computer environment. In one aspect of the present invention, a request manager receives a request associated with meta data corresponding to data that is maintained separately from the meta data. In another aspect, the request manager informs a data object manager of an anticipated request that will be received by the data object manager to enable it to prepare for the anticipated request. The data object manager commences preparing for the anticipated request in response to being informed of the anticipated request to facilitate a reduction in data access time. In one example of a computing environment utilizing one or aspects of the invention, a storage subsystem comprising a data object manager prepares for the anticipated request by pre-fetching data blocks from storage media into a cache.

摘要： A method for processing a point-in-time copy of data associated with a logical storage volume where the data to be copied is stored in a striped or parallelized fashion across more than one physical source volume. The method includes receiving a point-in-time copy command concerning a logical volume and distributing the point-in-time copy command in-band to each of the physical source volumes containing a portion of the striped data. The method also includes establishing a point-in-time copy relationship between each physical source volume and one of a corresponding set of multiple physical target volumes. The method further includes copying the data stored on each physical source volume to the corresponding physical target volume. The in-band copy command and the striped data may be distributed over I/O channels between a server and the physical storage and processed sequentially.
