Modulation schemes are disclosed that include one or more zero-power modulation states, in which the transmitter briefly emits zero or very low signal for one resource element of a message in 5G or 6G networking. In phase-modulated examples such as QPSK, an additional zero-power state can provide higher information density and shorter message sizes. In pulse-amplitude modulated schemes, the additional states can have zero power in one or both branches, thereby providing multiple additional modulation options. The receiver can readily detect and interpret the zero-power modulation states. Messages transmitted including the zero-power modulation states are generally shorter (in time or in bandwidth) due to the higher information density, and involve substantially lower energy expenditure because the message size is smaller, and because some of the states have zero or very low transmission power. Receivers also can benefit from the smaller size messages. Special zero-power states can be reserved for indicating the start and end of each message, for example.

The second portion of the volumes that operates in the passive mode consumes fewer resources than the first portion of the volumes that operates in the active mode. The first portion of the plurality of volumes and the second portion of the plurality of volumes are adjusted over time based on activity of each volume of the plurality of volumes.

To provide more uniform performance levels for solid state drive (SSDs), the static power level used by an SSD in an idle state is measured and used to determine a static power offset for each of the drives. The static power offset is set as a parameter for the SSD and used to offset a received power supply level for use on the drive. For a data storage system of multiple SSDs, a common scaling factor can be used to set the degree to which the static power offset is implemented, allowing for a choice between uniformity of power and uniformity of performance for the SSDs of a data storage system.

Processing functions are offloaded to a memory controller for nonvolatile memory by a host in connection with write data. The nonvolatile memory executes these functions, producing processed data that must be written into memory; for example, the offloaded functions can include erasure coding, with the nonvolatile memory controller generating redundancy information that must be written into memory. The memory controller holds this information in internal RAM and then later writes this information into nonvolatile memory according to dynamically determined write time and/or destinations selected by the host, so as to not collide with host data access requests. In one embodiment, the memory is NAND flash memory and the memory controller is a cooperative memory controller that permits the host to schedule concurrent operations in respective, configurable virtual block devices which have been configured by the host out of a pool of structural flash memory structures managed by the memory controller.

A system for tracking metadata changes and recovering from system interruptions. With host I/O, corresponding metadata incremental changes are aggregated and stored in a write-ahead log before being performed to their in-memory buffers. As those buffers are flushed, checkpoints are created and stored in the log. As the log wraps to the start, older entries are overwritten after they are freed from any remaining dependencies by newer checkpoints. If metadata entities have not created new checkpoints, they are instructed to in order to free up space for new aggregated batches and checkpoints. After an interruption, the wrap point is located in the log. From the wrap point, the log is scanned backwards to provide checkpoints to metadata entities. The log is then scanned forwards to perform changes specified by aggregated batches. The metadata entities' volatile memory states are recovered to what they were before the interruption.

Storage objects and targetless snaps of the storage objects are represented using a system replication data pointer table (SRT), direct index lookup (DIL) tables, and virtual replication data pointer tables (VRTs). The SRT is a system level track-based data structure that stores metadata indicative of the actual (physical layer) allocations for all targetless snapshots in a storage array. The size of the SRT in terms of total entries corresponds to the overall storage capacity of the managed drives of the storage array. Each utilized entry of the SRT includes backend metadata with a pointer to a managed drive and metadata that identifies the associated storage object and track via the VRTs and DIL tables. SRT metadata is created and discarded as backend allocations are utilized and freed so the SRT is a dynamic data structure that can efficiently adjust its size and corresponding memory requirements.

Efficient handling of disk input/output (I/O) operations is disclosed for a storage system supporting a doubly mapped redundant array of independent nodes. Delegating I/O operation management to a mapping layer component can support adapting I/O operation performance based on a topology of a real cluster supporting doubly mapped clusters. In traditional techniques, some corresponding real node topologies can result in inefficiently moving data from a first real node to a second real node and then promptly moving it back from the second real node to the first real node. These, and other, inefficient disk I/O conditions can be mitigated or avoided based on the presently disclosed techniques that can support more direct access to mapping information. Moreover, the disclosed techniques can support proportionately adapting an order of performing I/O operations due to the inherent isolation of real nodes and real clusters in accord with the disclosed subject matter.

The selective rejection of touch contacts in an edge region of a touch sensor panel is disclosed. In addition, by providing certain exceptions to the rejection of edge contacts, the functionality of the touch sensor panel can be maximized. Contacts in edge bands around the perimeter of a touch sensor panel can be ignored. However, if a contact in the edge band moves beyond a threshold distance or speed, it can be recognized as part of a gesture. To accommodate different finger sizes, the size of the edge band can be modified based on the identification of the finger or thumb. Furthermore, if contacts in the center region of a touch sensor panel track the movement of contacts in the edge band, the contacts in the edge band can be recognized as part of a gesture.
