Abstract: A storage apparatus coupled to a host device comprises a virtual volume which is a virtual logical volume configured of multiple virtual areas and a pool configured of multiple actual area groups of different performances. A controller manages pool status information which is the information showing which actual area is allocated to which virtual area and access load related to the virtual areas. A management system of the storage apparatus, with reference to the pool status information at multiple points of time from past to present and an access load threshold which is equal to or larger than 1, estimates the used capacity of each actual area group at points of time in the future, calculates the installed/removed amount of each actual area group which is the difference between the estimated used capacity and the current storage capacity, and performs the processing based on the calculated result.

Abstract: An aspect of the invention is directed to a plurality of MDSs (metadata servers) in a distributed storage system which includes data servers storing file contents, each MDS having a processor and a memory and storing file system metadata. Directories of a file system namespace are distributed to the MDSs through referral directories referring to real directories using hash value of inode number of each of the referral directories. During a process to create a directory in the file system namespace, a first MDS dynamically creates a referral directory in the first MDS, and creates a real directory in a second MDS, the referral directory in the first MDS referring to the real directory in the second MDS by maintaining location information of the real directory in the second MDS, the real directory in the second MDS containing the file system metadata for the directory in the file system namespace.

Abstract: In some examples, a video analysis framework receives one or more video streams including a plurality of video frames. The framework may perform region detection on the frames, and may perform feature detection/extraction on the regions. Based on the extracted features, the individual video frames may be sent to particular pipelines of a plurality of pipelines designated for performing different video analysis tasks. The framework may determine respective indexed profiles to associate with particular detected regions for indexing the individual video frames or regions thereof. In some cases, resources may be allocated among the pipelines based on a priority definition. For instance, the priorities in the priority definition may be updated dynamically based on context of the received frames. Further, a log of recent video analysis results may be maintained to enable indexing, annotation, augmentation, and searching for related content without having to access information in a storage system.

Abstract: In a storage system 1, a storage apparatus A having a first pool 1430 including segments as unit storage areas and a storage apparatus B having a second pool 1430 having the same configuration are communicably connected to each other. In the storage system, an external volume identifier is associated with a logical volume 1420 included in the first pool 1430, the external volume identifier being used by a controller 1500 in the storage apparatus B to identify and manage the logical volume 1420 as an external volume 1425 that is a virtual volume in the storage apparatus B. Moreover, a volume identifier 5110 of the logical volume 1420 included in the first pool 1430 is rewritten into the external volume identifier in order to enable the storage apparatus B to utilize the logical volume 1420 created from the first pool 1430.
