摘要： Disclosed is a system for performing an operation, such as a read or write operation, on a data block in a shared disk system. A first adaptor receives a request to perform an operation on a data block maintained in a data storage location. The first adaptor then determines whether the first adaptor controls access to the data block. The first adaptor performs the requested operation on the data block after determining that the first adaptor controls access to the data block. If the first adaptor does not control access to the data block, then the first adaptor transmits a first message to a second adaptor that controls access to the data block and requests control of access to the data block. After receiving the first message, the second adaptor transfers control of access to the data block to the first adaptor. The second adaptor then transmits a second message to the first adaptor that the first adaptor controls access to the data block. After receiving the second message, the first adaptor performs the requested operation on the data block.

摘要： A change in workload characteristics detected at one tier of a multi-tiered cache is communicated to another tier of the multi-tiered cache. Multiple caching elements exist at different tiers, and at least one tier includes a cache element that is dynamically resizable. The communicated change in workload characteristics causes the receiving tier to adjust at least one aspect of cache performance in the multi-tiered cache. In one aspect, at least one dynamically resizable element in the multi-tiered cache is resized responsive to the change in workload characteristics.

摘要： A service level objective (SLO) violation is detected for a workload of a networked storage system, based on a performance metric not being satisfied for the workload. In response to detecting the SLO violation, a controller determines that changing a level of caching at a node of the networked storage system will improve the performance metric for the workload. The controller implements the change by adjusting an operation of a virtual cache appliance (VCA) of the networked storage system. The adjusting can be instantiating a new VCA, or adjusting the level of caching at an existing VCA. The adjusting can be for caching related to the workload itself, or it can be caching for an intertering workload.

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： Deduplication of data using a low-latency random read memory (LLRRM) is described herein. Upon receiving a block, if a matching block stored on a disk device is found, the received block is deduplicated by producing an index to the address location of the matching block. In some embodiments, a matching block having a predetermined threshold number of associated indexes that reference the matching block is transferred to LLRRM, the threshold number being one or greater. Associated indexes may be modified to reflect the new address location in LLRRM. Deduplication may be performed using a mapping mechanism containing mappings of deduplicated blocks to matching blocks, the mappings being used for performing read requests. Deduplication described herein may reduce read latency as LLRRM has relatively low latency in performing random read requests relative to disk devices.
摘要翻译：本文描述了使用低延迟随机读取存储器（LLRRM）的数据重复数据删除。在接收到块时，如果找到存储在磁盘设备上的匹配块，则通过向匹配块的地址位置产生索引来对所接收的块进行重复数据删除。在一些实施例中，具有参考匹配块的具有预定阈值数量的关联索引的匹配块被传送到LLRRM，阈值数目为一个或更大。可以修改相关索引以反映LLRRM中的新地址位置。重复数据删除可以使用包含对重复数据删除的块对匹配块进行映射的映射机制来执行，映射用于执行读请求。这里描述的重复数据删除可以减少读取延迟，因为在执行相对于磁盘设备的随机读取请求时，LLRRM具有相对较低的延迟。

摘要： A mechanism is provided to automatically retrieve zoning best practices from a centralized repository and to ensure that automatically generated zones do not violate these best practices. A user selects a set of hosts and storage controllers. The user also selects a guidance policy for creating the zone, and also selects a set of validation policies that must be enforced on the zone. If the user selects a guidance policy and a validation policy combination that is incompatible, the mechanism allows the user to change either the selected guidance policy or the set of validation policies. If the user has selected consistent-zoning as a guidance policy, then the mechanism automatically selects a guidance policy that does not violate the known validation policies.

摘要： Provided is an article of manufacture, system and method for a management system for using host and storage controller port information to configure paths between a host and storage controller in a network. A management system is coupled to a network, wherein the management system communicates over the network with a plurality of hosts, storage controllers, and a network monitor to configure paths in the network between the hosts and the storage controllers in order for the storage controller to provide storage services to the hosts. The network monitor collects statistics from the components in the network. The management system obtains from the network monitor information on ports on at least one host, ports on at least one storage controller managing access to storage volumes, and at least one fabric over which the at least one host and storage controller ports connect. The management system gathers, for at least one host port and storage controller port, information on a connection metric indicating a number of paths in which the port is configured and a traffic metric indicating Input/Output (I/O) traffic at the port. The management system processes the connection and traffic metrics for the host and storage ports to select at least one host port and at least one storage controller port. The management system configures the at least one selected host and storage controller port pair to provide at least one path enabling the host to communicate with the selected storage controller port to access at least one storage volume managed by the selected storage controller.

摘要： Formulating an integrated disaster recovery (DR) plan based upon a plurality of DR requirements for an application by receiving a first set of inputs identifying one or more entity types for which the plan is to be formulated, such as an enterprise, one or more sites of the enterprise, the application, or a particular data type for the application. At least one data container representing a subset of data for an application is identified. A second set of inputs is received identifying at least one disaster type for which the plan is to be formulated. A third set of inputs is received identifying a DR requirement for the application as a category of DR Quality of Service (QoS) class to be applied to the disaster type. A composition model is generated specifying one or more respective DR QoS parameters as a function of a corresponding set of one or more QoS parameters representative of a replication technology solution. The replication technology solution encompasses a plurality of storage stack levels. A solution template library is generated for mapping the application to each of a plurality of candidate replication technology solutions. The template library is used to select a DR plan in the form of a replication technology solution for the application.

The at least one selected host and storage controller port pair are configured to provide at least one path enabling the host to communicate with the selected storage controller port to access at least one storage volume managed by the selected storage controller.
