Various mechanisms and workflows are described that can utilize power and/or carbon footprint-based metrics to manage storage unit usage and/or configuration, which can provide a more efficient and environmentally friendly computing environment. In some example configurations, storage system management mechanisms collect power consumption for storage units (e.g., individual drives, storage shelfs, nodes, clusters) and can utilize the power consumption information with other storage unit characteristics to generate power and carbon footprint metrics.

Storage device energy consumption evaluation and response

Methods and systems for a networked storage system are provided. A provisioning engine assigns a plurality of performance parameters in response to a provisioning request for provisioning a workload for storing data in a networked storage environment; identifies a demand for a plurality of resources of the networked storage environment for meeting the provisioning request, transforms historical available performance capacity by filtering any historical performance capacity data related to any transient event; and identifies at least a resource pair that can meet the identified demand based on the transformed historical performance capacity data.

Methods and systems for managing provisioning requests in a networked storage environment

A method and apparatus for a communications network that executes a medium access control (MAC) protocol that permits multiple access to a shared medium or shared switching fabric. The MAC protocol uses a BANDWIDTH_ALLOCATOR to regulate access to the network by sending a permission message to a NODE, allowing it to transmit to a specific set of NODEs for a specific length of time. The medium and switching fabric can carry one or more protocols, each of varying framing format and native bitrate. The switching fabric provides a connection-oriented bufferless data transport service that preserves frame ordering. An illustrative embodiment uses a slotted master/slave time-division multiplexed access (TDMA) scheme to allow flexible provisioning of network bandwidth.

Multi-protocol network interface card

A fiber-optic networking system that can survive a break in the fiber and restore full connectivity to all nodes in the network. The network can detect the presence of a cut in the fiber, locate the cut, recover from the cut, and restore the communication capacity that was available before the cut. The network is also capable of automatically determining the existence and identity of the nodes in the network, the distance of the node from the headend, and the executing procedures to handle both planned and unplanned (i.e., during a fault) removal of nodes from the network.

Fault tolerant optical data communication network having auto discovery

A method and apparatus for a communications network that executes a medium access control (MAC) protocol that permits multiple access to a shared medium or shared switching fabric. The MAC protocol uses a bandwidth allocator to regulate access to the network by sending a permission message to a node, allowing it to transmit to a specific set of nodes for a specific length of time. The medium and switching fabric can carry one or more protocols, each of varying framing format and native bitrate. The switching fabric provides a connection-oriented bufferless data transport service that preserves frame ordering. An illustrative embodiment uses a slotted master/slave time-division multiplexed access (TDMA) scheme to allow flexible provisioning of network bandwidth.

Integrated system and method for controlling telecommunication network data communicated over a local area network and storage data communicated over a storage area network

According to several aspects of the present invention, a network is monitored for status information indicative of the status of a manageable device within the network. A network manager receives the status information, and updates or initializes a device model in accordance with the status information. A state machine may be used to determine a new state for the device model, and to enable or disable the device model. The network manager may also take action to inquire as to the status of the manageable device, for example by polling the manageable device or by initiating a discovery process. The device model may be used by the network manager as a basis by which to control the manageable device, and thus control aspects of the communications within the network.
