Abstract: A method may include receiving, by a controller of a storage device and from a host device, a command to resize a first namespace of a plurality of namespaces stored in a non-volatile memory device of the storage device. The method may further include, relocating, by the controller, a physical block address for the non-volatile memory device from an entry in a virtual to physical table identified by a first index value to an entry in the virtual to physical table identified by a second index value, and in response to relocating the physical block address, updating, by the controller, a mapping, by a namespace table, to indicate an initial index value of a second namespace of the plurality of namespaces.

Abstract: A host interface communicates with a non-volatile memory (NVM) device over a bus. The host interface includes a first buffer, a second buffer and a scatter/gather list (SGL). The first buffer stores blocks of application data to be communicated to the storage device. The second buffer stores blocks of protection data added by the host interface with respect to the blocks of application data stored in the first buffer. The SGL utilizes a first descriptor type that includes a first buffer address, a first buffer interleave burst length, and a burst count, and a second descriptor type that includes a second buffer address, and a second buffer interleave burst length, wherein only a first descriptor and a second descriptor is required to interleave application data from the first buffer with protection data from the second buffer.

Abstract: In general, techniques of this disclosure describe usage monitoring of data partitions within a data storage device, such as a data storage device that implements elastic capacity. Techniques may be performed by a host device and a controller of a storage device, where the host device causes the controller to perform the techniques described herein. In general, the controller may create a data partition in the data storage device based on a maximum exposed logical size for the data partition, a maximum allocated logical capacity for the data partition, and an allocated physical capacity for the data partition. The controller may write one or more blocks of data to the data partition. The controller may also send an indication representative of physical space used in the data partition to a host device based on the written one or more blocks of data.

Abstract: An abort function for storage devices sets a “poison bit” flag in the command to be deleted while the command resides on a submission queue prior to being fetched by the SSD controller. In response to the set “poison bit” flag, a storage device controller aborts execution of the I/O command and returns an abort successful status reply to the completion queue.

Abstract: A driven pile anchor suitable for securing a tendon of a tension leg platform to the seafloor is supplemented with added weight. A load frame is added to the individual pile to accommodate ballast weights. Pre-manufactured ballast weights are placed on the frame to increase the holding power of the pile anchor system. In a second embodiment, the pile is intentionally plugged and installed with the plug intact. Pre-manufactured ballast weights are then placed inside the pile and may be held in place by gravity. In a third embodiment, the pile is a conventional driven friction pile installed with an underwater pile hammer. The pile is initially open but subsequently evacuated and intentionally plugged near its pile tip. Pre-manufactured ballast weights are placed inside the pile to increase its holding capacity. The first embodiment may be retrofitted to existing, driven-pile anchor systems.
