Abstract:
A method and apparatus for enabling communication between iSCSI/SAS host devices and iSCSI/SAS target devices via an iSCSI/SAS router is disclosed. In one embodiment, an iSCSI/SAS router includes iSCSI interfaces, SAS interfaces, and a mapping and routing logic. The mapping and routing logic is coupled to the iSCSI interfaces and the SAS interfaces. The mapping and routing logic virtualizes one or more SAS host and target devices to communicate with discovered one or more iSCSI host and target devices. Further, the mapping and routing logic virtualizes the one or more iSCSI host and target devices to communicate with discovered one or more SAS host and target devices.
Abstract:
An apparatus comprising a controller, one or more host devices and one or more storage devices. The controller may be configured to store and/or retrieve data in response to one or more input/output requests. The one or more host devices may be configured to present the input/output requests. The one or more storage devices may be configured to store and/or retrieve the data. The controller may include a cache memory configured to store the input/output requests. The cache memory may be configured as a memory allocation table to store and/or retrieve a compressed version of a portion of the data in response to one or more network parameters. The compressed version may be retrieved from the memory allocation table instead of the storage devices based on the input/output requests to improve overall storage throughput.
Abstract:
A system and method for establishing a storage area network (SAN) is described. The method includes providing a predefined template for inputting data associated with a SAN. A first tool may utilize the template to validate an entered SAN configuration based on accessing data in a database. A second tool may utilize the template to generate a valid SAN configuration, based on accessing SAN data in a database, if component data is entered. An animated configuration of a valid SAN is generated based on at least one of the input SAN configuration or the input component data.
Abstract:
An apparatus comprising a controller circuit and an array. The controller circuit may be configured to read/write data in response to one or more input/output requests. The array may be configured to present/receive data to/from the controller circuit in response to the input/output requests. The data may be only transmitted to/from the array after a successful authentication between (i) a first code embedded within each of the input/output requests and (ii) a second code stored on a non-volatile memory within the controller circuit.
Abstract:
An apparatus comprising a remote storage array, a primary storage array and a network. The remote storage array may be configured to (i) define a queue size based on a performance capability of the remote storage array, (ii) generate a multiplier based on resources being used by the remote storage array, and (iii) adjust the queue size by the multiplier. The primary storage array may be configured to execute input/output (IO) requests between the remote storage array and the primary storage array based on the adjusted queue size. The network may be configured to connect the remote storage array to the primary storage array.
Abstract:
A method comprising the steps of (A) generating a call for a first operating system at a host, (B) sending the call for the first operating system from the host to a storage array over a network, (C) generating a response to the call for the first operating system from the host, (D) sending the response from the storage array to the host over the network and (E) capturing and storing the response in a device.
Abstract:
A system comprising a scheduler, a first core, and a second core. The scheduler may be configured to prioritize a plurality of input/output (IO) requests. The first core may be configured to process one of the plurality of IO requests based on the prioritizing of the plurality of IO requests. The second core may be configured to process a different one of the plurality of IO requests based on the prioritizing of the plurality of IO requests.
Abstract:
An apparatus comprising an initiator circuit and a target circuit. The initiator circuit may be configured to (i) communicate with a network through a first interface and (ii) generate testing sequences to be sent to the network. The target circuit may be configured to (i) receive the testing sequences from the network through a second network interface and (ii) respond to the testing sequences.
Abstract:
An apparatus comprising a storage array, a controller, a cache storage area and a backup storage area. The storage array may include a plurality of storage devices. The controller may be configured to send one or more commands configured to control reading and writing data to and from the storage array. The commands may include volume configuration information used by each of the plurality of storage devices. The cache storage area may be within the controller and may be configured to store a copy of the commands. The backup storage area may be configured to store the copy of the commands during a power failure.
Abstract:
A method for capturing data comprising the steps of (A) handling a call for a first operating system at a storage library, (B) routing the call from the storage library to a controller firmware, (C) sending a response to the call from the controller firmware to the storage library, and (D) storing the response in a data store box for later use by the storage library.
