Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for managing storage devices. In some implementations, a memory controller receives a logical write request over a logical interface that the memory controller provides for accessing a non-volatile storage device. The logical write request indicates a logical address at which to write data to the non-volatile storage device. In response to receiving the logical write request, the memory controller sends a write request event to a host system. The memory controller receives a physical write command from the host system over a physical interface that the memory controller provides for accessing the non-volatile storage device. In response to receiving the physical write command, the memory controller stores the data in the non-volatile storage device according to the physical write command.

Managing storage devices

A drive placement or placement functionality can enable initial copies of data to be placed on a drive in reclaim unit (HRUs) in a manner which is probabilistically more efficient from a garbage collection (GC) perspective and leverages knowledge of a host or application using the data. The placement functionality enables the advantages of fine-grained placement functionality while simultaneously allowing a storage device or storage drive to maintain NAND or other management responsibility, and not allocate that responsibility to an application or host device using the device.

Storage design for host controlled logically addressed flexible data layout

An apparatus includes a host device and a data storage device. The host device is configured to store a first translation map for converting a logical sector to a logical erase unit. The data storage device includes a plurality of flash memory devices and a memory controller operationally coupled with the flash memory devices, each of the flash memory devices being arranged into a plurality of erase units, each of the erase units having a plurality of pages for storing data. The memory controller is configured to receive a second translation map from the host device, the second translation map for converting a logical erase unit to a physical erase unit within the flash memory devices, and store the second translation map in a memory module on the data storage device.

Use of a logical-to-logical translation map and a logical-to-physical translation map to access a data storage device

A packet handling detection system detects a packet handling device between an originating device and a detection device by analyzing one or more transmission parameters of a packet received at the detection device.
