The present invention is a system for implementing a meta-disk aggregation model for storage controllers. The system includes a storage controller configured for communicatively coupling with a server. The system further includes a meta-disk drive group having a plurality of disk drives, the meta-disk drive group configured for being communicatively coupled with the storage controller, each of the plurality of disk drives including a drive interface connector. Additionally, each drive interface connector of the plurality of disk drives of the meta-disk drive group is configured for being communicatively coupled to each of the remaining drive interface connectors of the plurality of disk drives, thereby allowing the plurality of disk drives to communicate as a single device with the storage controller.

System and method for implementing a meta-disk aggregation model for storage controllers

The present disclosure provides a methodology by which disk level access for storage drives of a storage array may be highly secured based on permission settings applied to the driver interface of the storage drives. Based on specific set of access rules, a security component applies security profiles to permit/deny access to an individual storage drive, sets the storage drive with a first security level, monitors for a triggering event, and sets the storage drive to a second (more restrictive) security access level in response to the triggering event. In addition, the security component generates an alert in response to the triggering event. Thus, disk level access permissions are applied at a driver interface layer and permissions are applied based on administrator-defined policies. The present disclosure provides for complete lock-down of data permissions, management and/or restriction of IO loads, and protection of 'read-only' data integrity from overwrites.

Method and system for secured drive level access for storage arrays

The present invention is directed to a method and system for detecting component level changes in a storage area network during power off state is provided. Storage profile changes may be utilized for monitoring components during a power cycle period of a storage array system coupled to a SAN. During the power on state of the storage array system, a storage profile (an on-power-storage profile) is collected and time stamped after predefined set of trigger points. Another storage profile (an off-power-storage profile) of the same storage array system may be collected immediately after a power cycle. The two versions of the storage profiles are compared immediately after the off-power-storage profile is created to determine whether the predetermined condition happened. A delta file may be generated after the comparison of the two versions of storage profiles. Each detected conditions may be logged in a log file of the storage array system.

Method for detecting changes in a storage area network without external tools and hardware

A device may include a card including a card connector and/or a card edge lockshield disposed on at least a card connector first side. Additionally, a computer system may include a motherboard including at least one mating connector and/or at Least one card including a card connector and a card edge lockshield disposed on at least a card connector first side. Further, a method for providing the device and/or computer system is disclosed.

Card edge connector device and method

Peer-to peer licensing tracking and control is disclosed. In one embodiment, a method may include individually disabling a controller module when a code to activate the controller module is different from a number embedded in the controller module, and automatically disabling the controller module when the number is associated with another controller module communicatively coupled to the controller module. The method may further include a master controller module periodically querying one or more of controller modules communicatively coupled to the master controller module. The querying may identify the number and the feature associated with each of the controller modules to store in a validation module of the master controller module as a database. When the number of the controller module matches with one or more numbers of the controller modules listed in the database, the controller may be deactivated.

Peer-to-peer license tracking and control

Circuits, systems and methods for improved monitoring of status of a storage controller in a storage system. A monitoring circuit external to the storage controller is adapted to couple to the internal bus structure within the storage controller. The monitoring circuit is adapted to sense status of the storage controller by monitoring bus transactions within the storage controller that indicate status of the control and/or of the storage system. In one aspect the monitoring circuit saves sensed status in a memory associated with the circuit. In another aspect, the monitoring circuit includes a network interface to transmit sensed/saved status to an external data processing system.

Circuit, systems and methods for monitoring storage controller status

The present invention is a method and system for manufacturing an electronic device, such as a data storage device. The method includes generating a register including a desired device configuration. The register may include an identifier and radio signal information associated with the component so that the component may be tracked via a radio frequency identification device (RFID) physically associated with the component. Radio signals are monitored for signals associated with the component such as prior to inclusion into the electronic device to prevent improper assembly. An alert may be provided if a radio signal associated with a component included in the desired configuration is not present. The radio signals determined during monitoring are verified with the radio signals associated with the components included in the register. The components are assembled into the electronic device (or partially assembled device). The radio signal(s) are monitored to ensure the components were actually incorporated into the electronic device prior to proceeding with additional production.
