Abstract: The flame arrester is optimized for installation within fuel containers. The flame arrester has an elongate, generally cylindrical skeletal frame having opposing first and second ends. The first end is configured as a mounting flange adapted for permanent, immovable installation within the tank or container and the second end may include a spring-loaded check valve. The frame is covered by a woven or nonwoven textile material, or alternatively, by a porous or foraminous sheet material. Fuel and vapors pass through the cylindrical textile wall, the porosity of the textile serving to prevent flame propagation through the textile material. The frame is formed of a flexible, fuel-impervious plastic material to allow the flame arrester to be bent or curved for installation within a curved tube.

Abstract: Controlling I/O operations with a storage device includes establishing a quota that corresponds to a maximum amount of data to store on the storage device in a given amount of time, determining if processing an I/O operation would cause the quota to be exceeded, and performing the I/O operation if the quota is not exceeded. The quota may be provided in I/O operations per second or as I/O throughput. Controlling I/O operations with a storage device may also include accumulating credit in response to a rate of I/O operations being less than the quota and performing I/O operations when the quota is exceeded in response to the credit being greater than zero. The credit may be decreased if an I/O operation is performed when the quota is exceeded.

Abstract: A storage node uses storage descriptors for provisioning, monitoring and reporting. The storage descriptors indicate available storage resource capabilities and storage resource requirements for particular applications or types of applications using a common set of metrics. The storage node scales requirements to approximate a particular deployment scenario and then compares available capabilities and requirements as indicated by the storage descriptors.

Abstract: Validating a segment is disclosed, including: determining that a stored segment meets a validation criterion; and adjusting GPS data associated with the stored segment using aggregated GPS data.

Abstract: The disclosure provides an in-situ system and method for transferring a load from a tensioned flexible link between at least two bodies, such as between a buoyancy can and a subsea riser or between a moored offshore platform and a pile. The system and method provides a tether assembly having a hydraulic cylinder and/or a transfer assembly, where the hydraulic cylinder is configured upon actuation to decrease a distance between the two bodies; and the transfer assembly includes a mechanical interlock configured upon actuation to maintain the decreased distance between the two bodies independent of the hydraulic cylinder. The mechanical interlock can include various embodiments that can be selectively activated and deactivated position to allow the hydraulic cylinder to operate at various times in the transfer process. A support assembly can provide additional support to the flexible link independent of or in addition to the transfer assembly.

Abstract: Migrating data from an old storage device to a new storage device includes creating new paths to the new storage device, freezing old paths to the old storage device, transferring metadata corresponding to the old storage device to the new storage device, where state information is transferred from the old storage device to the new storage device, and thawing the new paths. Migrating data from an old storage device to a new storage device may also include creating new volumes on the new storage device and transferring data from the old storage device to the new storage device. Migrating data from an old storage device to a new storage device may also include dismantling the old paths.

Abstract: Global memory of a storage system may be used to provide NVRAM capabilities to guest operating systems accessing the storage system. The non-volatility of NVRAM (i.e. that retains its information when power is turned off) provides that an NVRAM device provided by global memory may be used as a journaling device to track storage operations and facilitate recovery and/or failover processing in a storage system without needing to add additional hardware and/or other installed devices. Use of the global memory according to the system described herein to provide an NVRAM device, that may function as a journaling device, provides for the speeding up of transactions, thereby improving metadata intensive operations performance and reducing recovery time and/or failover time of a storage system without adding additional hardware support.

Abstract: Described are techniques for performing path selection. A data operation is received for a metadevice comprising a plurality of metadevice members. A first of the plurality of metadevice members is determined. The first member is the member to which the data operation is directed. In accordance with a load balancing technique for the first metadevice member, path selection is performed to select a first of a plurality of paths. The metadevice is accessible over each of the plurality of paths. The data operation is sent over the first path.

Abstract: Described are techniques for performing processing in a data storage system. A client application executing on a host is identified as a candidate for migration to the data storage system. First data used by the client application is stored on one or more physical storage devices of the data storage system. The client application is migrated to the data storage system for temporary execution on the data storage system. The client application is executed on the data storage system for a time period using a first portion of resources of the data storage system allocated for exclusive use by migrated client applications executing on the data storage system.

Abstract: Described are techniques for migrating data from a source device of a source data storage system to a target device of a target data storage system. The target data storage system is configured to operate in accordance with a spoofing mode and a pass-through mode. A first set of commands from the host are processed for the target device when in the pass-through mode and the spoofing mode with respect to the target device. Data is migrated from the source device to the target device. The target data storage system is configured to operate in an echo mode for the target device and processes a second set of commands from the host when in the echo mode for the target device using information stored in the cache from processing the first set of commands.
