20110040942 | SYNCHRONIZATION OF REPLICATED SEQUENTIAL ACCESS STORAGE COMPONENTS - Various embodiments for synchronization of source and replicated instances of sequential access storage components in a computing environment by a processor device are provided. A replication synchronization table (RST) is configured for the source instance. The RST is adapted for recording compacted information for at least one of a truncate and an erase operation applied on the source instance. The RST of the source instance is updated at a source component with the compacted information. The updated RST is transmitted from the source instance to the replicated instance. Based on the RST of the source instance and the RST of the replicated instance, data representative of a most recent position on the source component from which data should be transmitted to a replicated component to achieve a full synchronization is determined. | 02-17-2011 |
20120144149 | CAPACITY MANAGEMENT IN DEDUPLICATION STORAGE SYSTEMS - Various embodiments for capacity management in a deduplication computing storage environment by a processor device are provided. A deduplication storage capacity is estimated as a function of an expected deduplication ratio, the expected deduplication ratio being a combined average of a current deduplication ratio and a configured deduplication ratio, the current deduplication ratio depending on the data currently stored in the deduplication storage, and the configured deduplication ratio being an estimate made at a configuration stage of the deduplication computing storage environment. | 06-07-2012 |

20140040671 | SECURING CRASH DUMP FILES - In a computer storage system, crash dump files are secured without power fencing in a cluster of a plurality of nodes connected to a storage system. Upon an occurrence of a panic of a crashing node and prior to receiving a panic message of the crashing node by a surviving node loading, in the cluster, a capturing node to become active, prior to a totem token being declared lost by the surviving node, for capturing the crash dump files of the crashing node, while manipulating the surviving node to continue to operate under the assumption the power fencing was performed on the crashing node. | 02-06-2014 |
