摘要： An improved technique for storing I/O metrics includes assigning metric values to data buckets held in kernel memory. Each data bucket covers a particular range of values of a respective metric and is configured as a counter, whose count is incremented each time the multipathing driver obtains or computes a metric value that falls within the range of the data bucket. Bucket counts can be read by an external program to obtain aggregate information about I/O metrics over time. The aggregate information can be fed back to the multipathing driver to enable improved selections of paths for conveying data to and from a storage array.

摘要： A processing platform comprises at least one server, computer or other processing device having a processor coupled to a memory, and implements a plurality of modules for adaptive optimization across an information technology (IT) infrastructure. The modules include a collector configured to gather information from the infrastructure, an analyzer coupled to the collector and configured to analyze the information gathered by the collector, a policy module specifying a plurality of policy sets, and a controller that is coupled to the collector, the analyzer and the policy module. The controller is configured to adjust one or more parameters of the infrastructure via corresponding control points. Associated with the analyzer is a situational analysis framework configured to periodically select and deploy for use by the controller a particular one of the specified plurality of policy sets responsive to changing operating conditions of the infrastructure. The infrastructure may comprise a virtual data center (VDC) or other type of virtual infrastructure.

摘要： In one aspect, a method of compressing data includes splitting an I/O into smaller I/Os based on a throughput of I/Os in a queue, a smaller I/O is equal or smaller than a block size. The method also includes storing the smaller I/Os in the queue. The method further includes asynchronously compressing the smaller I/Os.

摘要： 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.

摘要： One embodiment is a method and apparatus for managing a virtual data storage object in a computer system including at least one host and at least one storage device that present at least one storage disk to the host as a storage resource. The host includes at least one of an LVM and a file system. The virtual data storage object is created so that at least one of a logical volume and a file is employed as a storage resource to store data stored to the virtual data storage object. Another embodiment forms a virtual data storage object with data images stored on logical volumes from LVMs on different hosts. A further embodiment forms a virtual data storage object with one data image stored to a disk and another stored to a logical volume. Another embodiment is directed to a method and apparatus for distributing the metadata that defines a virtual storage object about the computer system.
