In an array of solid-state drives (SSDs), SSDs in the array are each configured to initiate generation of additional erased memory blocks when an initiation command is received from a host or when the number of erased memory blocks in the SSD falls below a minimum threshold of erased memory blocks for the SSD. The minimum threshold value may be adjusted by the host.

A method comprises collecting data from a computing environment comprising one or more storage devices, wherein the data comprises information identifying assignments of the one or more storage devices to one or more servers in the computing environment. In the method, the data is analyzed using one or more machine learning algorithms, wherein the analyzing comprises predicting whether a given configuration of the one or more storage devices in combination with the one or more servers is a specified configuration. The method also includes generating a storage configuration recommendation for a user based on the analysis, and transmitting the storage configuration recommendation to the user.

Some embodiments include apparatuses and methods using memory cells and a control unit to suspend an erase operation performed on a first portion of the memory cells and to suspend a program operation performed on a second portion of the memory cells while the erase operation is suspended. The control unit includes register circuitry to store status information indicating that the program operation is suspended while the erase operation is suspended.

Techniques for the storage management involve, in response to detecting that a storage device is plugged into the storage system, determining, at a computing device of a storage system and based on attributes of the storage device, a target interface device matching the storage device from a plurality of types of interface devices in the storage system, the interface device managing the storage device having attributes matching one of the plurality of types; determining an association between the storage device and the target interface device; and generating, based on the association, information characterizing a state of the storage device in the computing device. In this way, it is possible to support at least two different types of disks in the existing storage system, improving the compatibility and scalability of the system.

A computer-implemented method according to one embodiment includes receiving, at a peripheral device via an in-band interface, a predetermined command; determining, by the peripheral device, a predetermined identifier within the predetermined command; and implementing, by the peripheral device, parameter data associated with the predetermined identifier, in response to the determining.

A switching device is implemented in a network-attachable data transfer device to provide data storage access to other such devices. In some embodiments, network-attachable data transfer devices are arranged in a clustered configuration to provide various computational and storage services. When one or more devices of the cluster fails, various implementations associated with the switching device, via an external data interface, provide operational mitigation, optimized data recovery, and efficient reinstatement of normal operation of the cluster.
