Abstract: One or more techniques and/or computing devices are provided for communicating storage controller failures utilizing service processor traps. A first storage controller, of a first storage cluster, has a disaster recovery relationship with a second storage controller of a second storage cluster. The first storage controller comprise a first service processor configured to monitor health of the first storage controller. Responsive to identifying a failure of the first storage controller, the first service processor uses stored communication configuration of a second service processor of the second storage controller to send a service processor trap to the second service processor. In this way, the second service processor initiates a switchover operation by the second storage controller to provide clients with failover access to data previously available through the first storage controller before the failure.

Abstract: The present disclosure relates to processes for inverting oligonucleotide probes in an in situ synthesized array. These processes can be used to reverse the orientation of probes with respect to the substrate from 3?-bound to 5?-bound. These processes can also be used to reduce or eliminate the presence of truncated probe sequences from an in situ synthesized array.

Abstract: Methods, non-transitory machine readable media, and computing devices that manage data storage fabric health are disclosed. With this technology, a network model is applied to network data determined from monitored network traffic exchanged between storage nodes and via network connections over a cluster fabric to generate a health score for the cluster fabric. A cause of health degradation in the cluster fabric is determined based on an analysis of the network data, when the health score indicates that health of the cluster fabric is degrading. A corrective action is automatically initiated based on the cause of health degradation in the cluster fabric. With this technology, cluster fabrics in data storage networks are more effectively monitored for health degradation and, advantageously, corrective actions can be preemptively initiated to improve performance.

Abstract: One or more techniques and/or computing devices are provided for automatic switchover implementation. For example, a first storage controller, of a first storage cluster, may have a disaster recovery relationship with a second storage controller of a second storage cluster. In the event the first storage controller fails, the second storage controller may automatically switchover operation from the first storage controller to the second storage controller for providing clients with failover access to data previously accessible to the clients through the first storage controller. The second storage controller may detect, cross-cluster, a failure of the first storage controller utilizing remote direct memory access (RDMA) read operations to access heartbeat information, heartbeat information stored within a disk mailbox, and/or service processor traps.

Abstract: An adjustable neck for a vent cap includes a housing having a mount and a cylindrical body, where the cylindrical body includes an inner surface. The adjustable neck also includes adjustable straps arranged to form an adjustable inner diametrical surface disposed radially inward from the cylindrical body of the housing, relative to a central axis of the adjustable neck. The adjustable inner diametrical surface is configured to engage an outer pipe surface. The adjustable straps are coupled to the inner surface of the cylindrical body. The adjustable neck also includes legs coupled to the adjustable straps and to the mount, where the cylindrical body is configured to be rotated relative to the mount and the legs to adjust a dimension of the adjustable inner diametrical surface to correspond to the outer pipe surface.

Abstract: Exemplary embodiments provide methods, mediums, and systems for efficiently moving data between cluster nodes. Upon receiving a request to read or write data at a first cluster node that is in communication with a client, the first node effects the transfer to or from a second cluster node. The transfer is carried out using a combination of remote data memory access (“RDMA”), or a similar technique that bypasses a part of the network stack, and transport control protocol (“TCP”), or a similar technique that does not bypass a part of the network stack. The data is transferred using RDMA, while certain control messages are sent using TCP. By combining RDMA content transfers and TCP control messages, data transfers can be carried out faster, more efficiently, and with less processing overhead. Other embodiments are described and claimed.

Abstract: One or more techniques and/or devices are provided for storage virtual machine relocation (e.g., ownership change) between storage clusters. For example, operational statistics of a first storage cluster and a second storage cluster may be evaluated to identify a set of load balancing metrics. Ownership of one or more storage aggregates and/or one or more storage virtual machines may be changed (e.g., permanently changed for load balancing purposes or temporarily changed for disaster recovery purposes) between the first storage cluster and the second storage cluster utilizing zero-copy ownership change operations based upon the set of load balancing metrics. For example, if the first storage cluster is experiencing a relatively heavier load of client I/O operations and the second storage cluster has available resources, ownership of a storage aggregate and a storage virtual machine may be switched from the first storage cluster to the second storage cluster for load balancing.

The fermenting wine is contained inside a single-use plastic bag, eliminating cleaning. A reusable rubber bladder is inflated periodically to squeeze the cap and disperse it. At the conclusion of the fermentation, a perforated device is inserted into the fermentation bag and pneumatic bladders are sequentially inflated to press out the wine while retaining the waste skins and seeds.

Abstract: Various embodiments are described herein for a system, method, and device for identifying focal source locations of electrophysiological activity in an organ. The system, method and device may also be used to guide catheter ablation of the organ. An electrogram signal can be obtained from a location in the organ, and it can be determined if the electrogram is periodic and, if so, the corresponding periodicity cycle length.

The location can be identified as a focal source location when the periodicity cycle length and the plurality of peaks have focal source characteristics. Methods are also described for identifying a direction of wave propagation and identifying multiple periodicities within an electrogram signal.

Abstract: Methods of extracting anthocyanins from corn kernels are disclosed. In embodiments, the methods may include fractionating the corn kernels into their constituent component parts. After fractionating, the pericarp fiber may be separated from the constituent component parts of the corn kernels. The pericarp fiber may be steeped in an aqueous solution to extract anthocyanins from the pericarp fiber. After steeping, the aqueous solution may contain greater than about 40% by weight of total extractable anthocyanins present in the corn kernels prior to fractionating.
