Abstract: Systems and methods for efficient deduplication and/or provisioning of LUNs are disclosed. A first unique data block pool for a first LUN of a plurality of deduplicated LUNs is accessed, the first unique data block pool comprising a first plurality of unique data blocks for representing data stored on the first LUN. A second unique data block pool for a second LUN of the plurality of LUNs is accessed, the second unique data block pool comprising a second plurality of unique data blocks for representing data stored on the second LUN. It is determined a correspondence metric for the first unique data block pool and the second unique data block pool exceeds a pre-determined threshold. The first LUN and the second LUN are joined to form a first combined LUN. The first unique data block pool and the second unique data block pool are joined.

Abstract: Improved techniques involve creating a feedback cycle between a framework for managing many data storage arrays and system for provisioning a data storage array using real-time usage statistics from the framework. Along these lines, a multi-system provisioning tool provides an initial configuration of storage systems in a datacenter; such an initial configuration includes provisioning of logical disks for each system. As this tool monitors activity within the datacenter, it generates live runtime data for each logical disk within each system. The tool then compares this live runtime data to external runtime data received from a central database and looks for anomalies in the live runtime data. Upon detecting an anomaly in a logical disk, the tool may respond by finding logical disks in other storage arrays from which storage resources may be swapped.

Abstract: Improved techniques involve comparing access patterns in a storage system to expected access patterns under similar circumstances. An intrusion detection system, in response to a suspected malicious application workload, collects information about a current session on the storage processor, e.g., application workload s running, users logged in, and timestamp, as well as parameters such as storage allocation requests sampled at prespecified intervals over a period of time. In a database that stores such sampled parameter values by application workload, user, and time, the system extracts the sampled parameter values having the application workload, user, and time corresponding to the current session. The system then compares the extracted sampled parameter values with the current parameter values and computes a difference. Based on the difference, the system determines whether the storage system is accessed by a malicious application workload.

Abstract: A method is used in retrieving data from data storage systems. A nonvolatile memory module connected to a data storage system is detected. The data storage system uses information stored in the nonvolatile memory module to initiate an action. Based on the information, the action is performed. The action includes retrieving data from the data storage system to the nonvolatile memory module.

Abstract: Improved efficiency in monitoring environmental conditions in the vicinity of an unattended computer system includes using the existing communication systems between the computer system and a network, to provide immediate information to users, emergency responders and anyone connected to the network. The system may also include an ability of the unattended computer system to receive a return message from the user ordering a physical action in response to the reported environmental condition, for example turning on a fire suppression system in response to a smoke alarm. The system may also include storage of environmental conditions and analysis of variations over time, as well as any interactions of various types of environmental conditions, such as giving more weight to a high temperature reading in conjunction with an elevated but not critical level of smoke.
