摘要： The techniques introduced here provide for enabling deduplication operations for a file system without significantly affecting read performance of the file system due to fragmentation of the data sets in the file system. The techniques include determining, by a storage server that hosts the file system, a level of fragmentation that would be introduced to a data set stored in the file system as a result of performing a deduplication operation on the data set. The storage server then compares the level of fragmentation with a threshold value and determines whether to perform the deduplication operation based on a result of comparing the level of fragmentation with the threshold value. The threshold value represents an acceptable level of fragmentation in the data sets of the file system.

摘要： A novel RDMA connection failover technique that minimizes disruption to upper subsystem modules (executed on a computer node), which create requests for data transfer. A new failover virtual layer performs failover of an RDMA connection in error so that the upper subsystem that created a request does not have knowledge of an error (which is recoverable in software and hardware), or of a failure on the RDMA connection due to the error. Since the upper subsystem does not have knowledge of a failure on the RDMA connection or of a performed failover of the RDMA connection, the upper subsystem continues providing requests to the failover virtual layer without interruption, thereby minimizing downtime of the data transfer activity.
摘要翻译：一种新颖的RDMA连接故障切换技术，可最大限度地减少上层子系统模块（在计算机节点上执行）的干扰，从而创建数据传输请求。新的故障转移虚拟层错误地执行RDMA连接的故障转移，以便创建请求的上级子系统不知道错误（可在软件和硬件中恢复）或RDMA连接发生故障，因为错误。由于上级子系统不知道RDMA连接上的故障或RDMA连接的已执行故障转移，上级子系统会继续向故障转移虚拟层提供请求，而不会中断，从而最大限度地减少数据传输活动的停机时间。

摘要： Collaborative management of shared resources is implemented by a storage server receiving, from a first resource manager, notification of a violation for a service provided by the storage server or device coupled to the storage server. The storage server further receives, from each of a plurality of resource managers, an estimated cost of taking a corrective action to mitigate the violation and selects a corrective action proposed by one of the plurality of resource managers based upon the estimated cost. The storage server directs the resource manager that proposed the selected corrective action to perform the selected corrective action.

摘要： Method and system for partially cloning a data container with compression is provided. A storage operating system determines if a portion of a source data container that is to be cloned includes a plurality of compressed blocks that are compressed using a non-variable compression group size. The operating system clones the plurality of compressed blocks with the non-variable compression group size and de-compresses a plurality of blocks of the data container that are not within the non-variable compression group size. The plurality of compressed blocks and the plurality of blocks that are not within the non-variable compression group size are then stored as a partially cloned copy of the source data container.

摘要： System and method for migrating data from a source storage site to a destination storage site. The data may be comprised within storage objects (e.g., flexible volumes). A base storage object may comprise a parent storage object and a storage object clone may comprise a storage object that is derived from the base storage object. As such, a hierarchical relationship exists between the base storage object and the storage object clone. The storage object clone may comprise a writable point-in-time image of the parent storage object. If a migration of the base storage object and the storage object clone is performed, then the hierarchical relationship between the base storage object and the storage object clone is retained after the storage objects are migrated from the source storage site to the destination storage site. As such, the system and method for migrating data may enable storage space and network bandwidth savings.
摘要翻译：将数据从源存储站点迁移到目标存储站点的系统和方法。数据可以包括在存储对象（例如，灵活的卷）内。基本存储对象可以包括父存储对象，并且存储对象克隆可以包括从基本存储对象导出的存储对象。因此，基本存储对象和存储对象克隆之间存在层次关系。存储对象克隆可以包括父存储对象的可写入时间点图像。如果执行基本存储对象和存储对象克隆的迁移，则在将存储对象从源存储站点迁移到目标存储站点之后，将保留基本存储对象和存储对象克隆之间的分层关系。因此，用于迁移数据的系统和方法可以实现存储空间和网络带宽的节省。

摘要： A request is received to remove duplicate data. A log data container associated with a storage volume in a storage server is accessed. The log data container includes a plurality of entries. Each entry is identified by an extent identifier in a data structures stored in a volume associated with the storage server. For each entry in the log data container, a determination is made if the entry matches another entry in the log data container. If the entry matches another entry in the log data container, a determination is made of a donor extent and a recipient extent. If an external reference count associated with the recipient extent equals a first predetermined value, block sharing is performed for the donor extent and the recipient extent. A determination is made if the reference count of the donor extent equals a second predetermined value. If the reference count of the donor extent equals the second predetermined value, the donor extent is freed.

摘要： The technique introduced here includes a system and method for identifying and mapping duplicate data objects referenced by data objects. The technique illustratively utilizes a hierarchical tree of fingerprints for each data object to compare the data objects and identify duplicate data blocks referenced by the data objects. A progressive comparison of the hierarchical trees starts from a top layer of the hierarchical trees and proceeds toward a base layer. Between the compared data objects (i.e., the compared hierarchical trees), the technique maps matching fingerprints only at the top-most layer of the hierarchical trees at which the fingerprints match. Lower layer matching fingerprints are neither compared nor mapped. Data blocks corresponding to the matching fingerprints are then deleted. Such an identification and mapping technique substantially reduces the amount of mapping metadata stored in data objects that have been subject to deduplication.

摘要： An extent-based storage architecture is implemented by a storage server receiving a read request for an extent from a client, wherein the extent includes a group of contiguous blocks and the read request includes a file block number. The storage server retrieves an extent identifier from a first sorted data structure, wherein the storage server uses the received file block number to traverse the first sorted data structure to the extent identifier. The storage server retrieves a reference to the extent from a second sorted data structure, wherein the storage server uses the retrieved extent identifier to traverse the second sorted data structure to the reference, and wherein the second sorted data structure is global across a plurality of volumes. The storage server retrieves the extent from a storage device using the reference and returns the extent to the client.

摘要： The present invention is a system and method which allows for a VTL system that supports thin provisioning to implicitly unmap unused storage. Such unmap operations may occur even though the VTL system does not receive any explicit unmap requests from its initiators. For example, if a system administrator knows that once a virtual tape drive of the VTL system has been partially overwritten, all previously written data sets on that virtual tape drive will never again be accessed, the system administrator may configure the VTL system so that it unmaps the entire remainder of the virtual tape drive on the first data overwrite.
摘要翻译：本发明是允许支持精简配置的VTL系统隐含地取消对未使用的存储器的映射的系统和方法。即使VTL系统没有从其启动器接收到任何明确的未映射请求，也可能发生这种取消映射操作。例如，如果系统管理员知道一旦VTL系统的虚拟磁带驱动器被部分覆盖，则该虚拟磁带驱动器上的所有先前写入的数据集将不再被访问，系统管理员可以配置VTL系统，使其在第一个数据覆盖时，将虚拟磁带驱动器的剩余部分取消映射。

摘要： A method and apparatus for enabling communication between iSCSI/SAS host devices and iSCSI/SAS target devices via an iSCSI/SAS router is disclosed. In one embodiment, an iSCSI/SAS router includes iSCSI interfaces, SAS interfaces, and a mapping and routing logic. The mapping and routing logic is coupled to the iSCSI interfaces and the SAS interfaces. The mapping and routing logic virtualizes one or more SAS host and target devices to communicate with discovered one or more iSCSI host and target devices. Further, the mapping and routing logic virtualizes the one or more iSCSI host and target devices to communicate with discovered one or more SAS host and target devices.
