摘要： A method and apparatus for metadata favored replication in an active/active topology. When replicating data objects between multiple storage systems, metadata is sent first while the associated data content is sent at a subsequent time. Metadata is stored and made visible on a target storage system thereby reserving the object path in a namespace to reduce collisions in the namespace. After metadata is transferred to the target storage system, the target system performs collision processing to determine if an object already exists in the namespace prior to receiving the transferred metadata. After collision processing is performed, the winning object is made visible for access on the target storage system regardless of whether the associated data content has been transferred to the target system.
摘要翻译：用于元数据的方法和装置有利于主动/主动拓扑中的复制。当在多个存储系统之间复制数据对象时，首先发送元数据，同时在随后的时间发送关联的数据内容。元数据被存储并在目标存储系统上可见，从而将命名空间中的对象路径保留以减少命名空间中的冲突。在将元数据传输到目标存储系统之后，目标系统执行冲突处理，以确定在接收传输的元数据之前对象是否已经存在于命名空间中。在执行冲突处理之后，无论相关联的数据内容是否被传送到目标系统，获胜对象都可以被存取在目标存储系统上。

摘要： To provide a retrieval space map in which the ratio of unnecessary files included in the retrieval result can be decreased. One or more retrieval object spaces (retrieval objects) in which a file suitable for a retrieval purpose exists at high possibility are predefined according to the retrieval purpose under a condition containing a number of retrieval objects, and the space in which a necessary file exists at high possibility can be searched by designating the retrieval object to be suited for the retrieval purpose at the time of retrieval.

摘要： The present disclosure relates to distributed storage of data objects in a cluster system, in which a data object is distributed across a group of node apparatuses in units of data blocks; and I/O access to the data object is managed based on metadata structures including a metadata structure being associated with a parent object of the data object and plural metadata structures being respectively associated with one of a plurality of child objects of the data object. For each child object, the metadata structure of the respective child object is stored to one of the node apparatuses of the group of node apparatuses for managing locations of data blocks of the data object and includes a root metadata node and one or more direct metadata nodes, optionally further including one or more indirect metadata nodes; and the metadata structure of the parent object is distributed across the plural node apparatuses of the group of node apparatuses for managing locations of child objects of the data object and includes, on each node apparatus of the group of node apparatuses, a root metadata node and one or more direct metadata nodes, optionally further including one or more indirect metadata nodes.

摘要： An "operate with missing region" feature of this disclosure allows the cluster to continue servicing reads for available regions even when some regions are missing. In particular, upon a given node failure condition, the cluster is placed in an effective read-only mode for all regions. The node failure condition typically is one where there has been a failure of an authoritative region copy and no backup copy is available. As used herein, "read-only" means that no client write or update requests will succeed while the cluster is in this state. Preferably, such requests are then re-tried. In this mode, all regions are only allowed to perform read operations. During the read-only state, the cluster continues to operate with missing regions, and missing regions are entered on the region map. The cluster then automatically recovers returning missing region(s), after which is leaves the read-only state.
摘要翻译：本公开的“操作缺少区域”功能允许集群即使在某些区域丢失时仍继续为可用区域服务读取。特别地，在给定节点故障条件下，将集群置于所有区域的有效只读模式。节点故障状态通常是权威区域副本发生故障且没有备份副本可用的情况。如本文所用，“只读”表示在集群处于此状态时，客户端写入或更新请求将不会成功。优选地，这些请求被重新尝试。在这种模式下，所有区域只能执行读操作。在只读状态期间，群集继续使用缺少的区域进行操作，并且在区域映射中输入缺少的区域。然后，群集将自动恢复返回的缺失区域，之后离开只读状态。

摘要： A distributed shared-nothing storage system including independent nodes connected to a network and a host that sends I/O processing to the data stored on the storage system. Each node is capable of performing its own recovery of partially written data and maintaining consistency of the data stored on the storage system. The nodes independently calculate the location of all the data across the node and independently balance the data, maintain consistency based on redundancy policy of the storage system and migrate data according to a location change. If a node determines it stores incomplete or damaged data, the node reconstructs the data it stores from replica data on other nodes. During migration of data between the nodes, I/O processing from the host is not interrupted.

摘要： An environmental controlling system to better preserve cut flowers and other flora in vase water. The system uses thermoelectric modules, heat exchangers, fans, power supply, and a thermal conductor to cool and/or heat the water in a flower vase as required. By cooling the water, formation of algae and formation of a callus on the cut stem is reduced. In addition, keeping the stems in water of optimal temperature controls production of ethylene and other phytohormones. These effects prevent premature wilting, leaf abscission, flower senescence, and reduces the care required to maximize the life of cut flowers and other flora. In the event of cold ambient conditions that might cause freezing, the flow of heat can optionally be reversed, warming the water in the vase to avoid freezing the stems and/or maintain optimum temperature and other conditions for a specific variety of flora.

摘要： This disclosure enables a user to incrementally increase or decrease the size of the cluster and, in particular, to incrementally increase or decrease the number of map regions implemented in a metadata manager associated with the cluster while maintaining availability of the cluster. In a representative embodiment, a configurable target map size is identified, either manually or programmatically. If the target map size is found to be within an acceptable value (given the available node configuration), a procedure to create a new map is triggered. The new map preferably is generated as follows. Initially, one or more new temporary region(s) are created either to split or join the existing regions. For each temporary region, the process also generates MDPL backup regions. Metadata from an original region (or regions) is then migrated to the temporary region(s). Once the migrations have been completed, the old region or regions are removed.

摘要： Methods, apparatuses and systems control user access to a data storage system including nodes providing data storage resources storing user-accessible primary data structures and user-accessible secondary data structures stored on the basis of a respective associated primary data structure, wherein the data storage system stores, for each secondary data structure, data structure metadata indicative of a parent data storage resource and an owner data storage resource of the respective secondary data structure. Upon receiving a user request to access a certain secondary data structure, the respective owner data storage resource of the certain secondary data structure is determined, and determine whether the user is allowed to access the certain secondary data structure based on an access control verification process which includes a determination whether the determined owner data storage resource of the certain secondary data structure is permitted to be accessed by the user.
