Abstract: The invention is directed to a primary data storage system for use in a computer network in which a network allows user computers to transfer data to/from the primary data storage system. In one embodiment, the primary data storage system implements a tiering strategy to move data between stores with different characteristics so as to match the characteristics of the data to the characteristics of one of the stores.

Abstract: The invention is directed to a primary data storage system for use in a computer network in which a network allows user computers to transfer data to and/or from the primary data storage system. In one embodiment of the invention, the storage processor operates to analyze the data associated with write block commands that relate to different storage locations in a data store system that is associated with the primary data storage system so as to identify the potential writing of the block(s) of the same data to the data store system and prevent the writing of such blocks of data.

Abstract: Apparatuses, systems, methods, and computer program products are disclosed for managing a journal. A method may include reordering storage commands based on different storage volumes associated with the storage commands. A method may include reordering storage commands based on different snapshots associated with the storage commands. A method may include adjusting a frequency of writing data from a write buffer based on a rate of write requests. A method may include adjusting a ratio of storage capacity for storing mirrored write data to storage capacity for storing non-mirrored read data.

Abstract: A data storage system configured for efficient mirroring of data between paired redundant controllers is provided. More particularly, in response to the receipt of customer data from a host for storage, a first controller segments the received customer data into one or more frames of data. In addition, the first controller determines or associates certain metadata for each frame of customer data, and inserts that metadata in the corresponding frame. The frames, including the metadata, are provided to a secondary controller. The secondary controller stores the customer data from a received frame in memory, and stores the corresponding metadata in another location of memory that is indexed to the location where the customer data was stored. The secondary controller may also associate a count value with each frame of data in order to distinguish the most recent frame of data should frames in memory have matching metadata.

Abstract: Methods and systems for managing user access to a storage system storage controller are provided. In particular, user login requirements and permissions are administered, and individual user and external user interface pairs are tracked, through a user table and a session table established as part of the storage system controller. The external user interfaces may be interconnected to the storage system controller through different networks and/or protocols. Notification of events to external interfaces is performed as part of a task running on the storage system controller. In particular, an event notification manager determines whether notification of an event should be provided in connection with active sessions, with the result that the storage system controller only sends notification of events that have not previously been reported to a user and external interface pair.

The external user interfaces may be interconnected to the storage system controller through different networks and/or protocols. User authentication and access levels are established with reference to a user table, while sessions for different user and external interface pairs are maintained in the session table.
