  • Patent number: 10803970
    Abstract: A Solid-State Disk (SSD) Manufacturing Self Test (MST) capability enables an SSD manufacturer to generate and load tests onto SSDs, run the tests, and gather results. The SSDs self execute the loaded tests when powered up. The self executing is while coupled to a host that loaded the tests or while coupled to a rack unable to load the tests but enabled to provide power to the SSDs. The rack is optionally cost-reduced to enable cost-efficient parallel testing of relatively larger numbers of SSDs for production. The host writes the tests to an ‘input’ SMART log of each SSD, and each SSD writes results to a respective included ‘output’ SMART log. The commands include write drive, erase drive, SATA PHY burn-in, delay, and stress mode. The SSD MST capability is optionally used in conjunction with an SSD virtual manufacturing model.

  • Publication number: 20140059278
    Abstract: Storage device FirmWare (FW) and manufacturing software techniques include access to FW images and communication of a manufacturing software tool. The manufacturing software tool enables download of the FW images into an I/O device and controlling a manufacturing test of the I/O device that is a storage device providing a storage capability. Execution of the downloaded FW images enables an I/O controller of the I/O device to provide the storage capability via operation with one or more selected types of flash memory devices. The selected types are selected from a plurality of flash memory types that the I/O controller is capable of operating with by executing appropriate ones of the FW images. Optionally the manufacturing test includes testing the storage capability of the I/O device. The techniques further include an SSD manufacturing self-test capability.

  • Patent number: 7996631
    Abstract: A system and method for accessing storage devices attached to a stateless client. In one embodiment, the system may include a server configured to execute an application and a stateless client coupled to the server, whereby a user interacts with the application. The system may further include a storage device locally coupled to the stateless client, where the storage device is accessible by the user via the server. In various specific implementations of the system, the storage device may be a solid-state mass storage device or a mass storage device employing magnetic or optical media. In another specific implementation of the system, the storage device may be locally coupled to the stateless client via an interface such as Universal Serial Bus (USB) or IEEE 1394 (e.g. FireWire).
