In one embodiment, a network of SSDs includes a switch with a plurality of powered ports configured to be communicatively coupled to a controller and a host client and a plurality of SSDs configured to be communicatively coupled to the plurality of powered ports. The switch is configured to deliver up to a predefined power level to each of the plurality of SSDs via the plurality of powered port. Each of the plurality of SSDs consumes power. The controller is configured to manage the predefined power level for each of the plurality of SSDs by identifying the power consumed by each of the plurality of SSDs and allocating a new power level to each of the plurality of SSDs based on the power consumed by each of the plurality of SSD. In one embodiment, the switch and the plurality of SSDs are configured to occupy a server rack space.

Power management for solid state drives in a network

Disclosed herein is a device and method for dynamically processing of a command within a storage system. This includes identifying a plurality of non-volatile memory storage locations of the storage system that have at least one operation parameter associated with the plurality of non-volatile memory storage locations. For each identified plurality of non-volatile memory storage locations, there is a determination whether a value of the at least one operation parameter exceeds a predetermined threshold value. That value is representative of operation effects of the storage system on a corresponding storage location of the identified plurality of non-volatile memory storage locations. During operation of the storage system, there is a throttling of execution of the command to access a storage location of the identified plurality of non-volatile memory storage locations that has the value determined to exceed the predetermined threshold value by a throttle amount determined to mitigate an effect of the value exceeding the predetermined threshold value.

Dynamic processing of storage command based on internal operations of storage system

In some arrangements, a manager of a storage system determines at least one abstracted memory structure for a tenant using a non-volatile memory of at least one non-volatile storage device. The abstracted memory structure includes at least one hardware storage unit of the non-volatile memory of the at least one non-volatile storage device. The at least one abstracted memory structure includes one or more of at least one virtual device corresponding to an application of the tenant or at least one domain corresponding to a volume of the application of the tenant. A virtual device mapping that maps the application of the tenant to the at least one hardware storage unit corresponding to the at least one virtual device is determined. A domain mapping that maps the volume to the at least one hardware storage unit corresponding to the at least one domain is determined.

Maintaining quality of service of non-volatile memory devices in heterogeneous environment

A system for storing data includes a controller, an Ethernet switch and a storage device. The controller is configured to receive data routing instructions, and manage forwarding rules of a switch forwarding table to implement the data routing instructions. The Ethernet switch is configured to receive data, access the switch forwarding table, and route the data to the storage device using the switch forwarding table.

System and method for storing data using software defined networks

A method of managing data storage using a management device that includes determining respective status information for a plurality of storage devices, and calculating, based on the status information, a respective cost for each of the plurality of storage devices using a cost function that includes one or more parameters including at least one of: a program/erase (P/E) parameter, a block error state parameter, a block error level parameter, and a workload parameter. The method further includes selecting a destination storage device of the plurality of storage devices based on at least some of the calculated costs, and writing data to the destination storage device.

Pool-level storage management

A resource management system in a data center one or more data storage resource providers and a transaction server. The transaction server is configured to receive, from a client, a request for read and/or write access for a data storage resource, the request comprising one or more specifications, to provide, to the one or more data storage resource providers, at least a portion of the request, and to receive, from the one or more data storage resource providers, respective responses to the request, the responses respectively comprising one or more allocation options. The transaction server is further configured to select one of the one or more allocation options for registration, and register the selected allocation option with a data manager. At least one of the one or more data storage providers is configured to provide the data storage resource in accordance with the registered allocation option.

Data storage resource management

Various implementations described herein relate to systems and methods for managing selective erasure in a Solid-State Drive (SSD) including receiving a selective erase command corresponding to erasing valid and invalid data mapped to a logical address and in response to receiving the selective erase command, erasing blocks in which one or more pages mapped to the logical address are located based on a mapping table that maps the logical address to the one or more pages. Both valid data and invalid data may be physically stored in one or more pages.

Selective erasure of data in a SSD

Various implementations described herein relate to a system including multiple nodes. Each node is one of a storage node, a compute node, or a computer-and-storage node. Each node includes a Bluetooth&#xae; connector configured to communicate over a Bluetooth&#xae; mesh network.

Low-power scalable nodes

A system for reading stored data may include one or more Ethernet drives and a controller, both configured to communicatively connect to a host device. The controller may receive a first read command from the host device, determine a first drive among the one or more Ethernet drives using the first read command and a mapping table, translate the first read command into a second read command, and send the second read command to the first drive. Responsive to receiving the second read command, the first drive may send a first remote data transfer instruction to the host device independent of the controller. The first remote data transfer instruction may include stored data read from the first drive to cause the host device to write the stored data read from the first drive to one or more memory buffers in the host device indicated by the second read command.

System and method for storing data using ethernet drives and ethernet open-channel drives

Various implementations described herein relate to systems and methods for predicting and managing drive hazards for Solid State Drive (SSD) devices in a data center, including receiving telemetry data corresponding to SSDs, determining future hazard of one of those SSDs based on an a-priori model or machine learning, and causing migration of data from that SSD to another SSD.

System and method for reduced SSD failure via analysis and machine learning

Various implementations described herein relate to systems and methods for providing data protection and recovery for drive failures, including receiving, by a storage device, a write request from a host operatively coupled to a storage device, and determining, by the storage device instead of the host, an XOR result by performing an XOR operation of new data and existing data. The new data is received from the host. The existing data is stored in the non-volatile storage.
