摘要:
Methods are provided for detecting and correcting dropped writes in a storage system. Data and a checksum are written to a storage device, such as a RAID array. The state of the data is classified as being in a “new data, unconfirmed” state. The state of written data is periodically checked, such as with a timer. If the data is in the “new data, unconfirmed” state, it is checked for a dropped write. If a dropped write has occurred, the state of the data is changed to a “single dropped write confirmed” state and the dropped write error is preferably corrected. If no dropped write is detected, the state is, changed to a “confirmed good” state. If the data was updated through a read-modified-write prior to being checked for a dropped write event, its state is changed to an “unquantifiable” state.

Embodiments relate to a computer for transmitting data in a network. The computer includes at least one data transmission port configured to be connected to at least one storage device via a plurality of paths of a network. The computer further includes a processor configured to detect recurring intermittent errors in one or more paths of the plurality of paths and to disable access to the one or more paths based on detecting the recurring intermittent errors.

Techniques are disclosed for managing a switch fabric. In one embodiment, a server system is provided that includes a midplane, one or more server cards, switch modules and a management controller. The midplane may include a fabric interconnect for a switch fabric. The one or more server cards and the switch modules may be operatively connected to the midplane. The switch modules may be configured to switch network traffic for the one or more server cards. The management controller may be configured to manage the switch modules via the fabric interconnect.

Methods, systems, and computer program products are provided for dynamic selective memory mirroring in solid state devices. An amount of memory is reserved. Sections of the memory to select for mirroring in the reserved memory are dynamically determined. The selected sections of the memory contain critical areas. The selected sections of the memory are mirrored in the reserved memory.
摘要:
A storage device comprising a storage medium having a plurality of sectors and a superset format. Each sector includes a header, a data section and a trailer, the data section sized to contain a number of bytes per sector equal to or greater than a maximum of subset formats to be supported. Meta data in a non-user portion of the storage medium includes a flag for indicating a subset format such that each sector is formatted to store less than the number of bytes.

An entirely disposable pet litter apparatus consisting of a rectangular box, resilient bag, and an insert to hold the bag against the inner walls of the container. A portion of the top wall of the container is removed creating a window to view the contents. The rectangular box can be constructed with corrugated cardboard with an FOL type design with locking tabs which reduces the need for adhesives during manufacture. Optional detachable supports and a bag cover can be installed through slits in the wall of the box to create of fully enclosed pet litter apparatus.

A spool for storing and transporting heavy strand material, particularly wire, includes a hollow shell with integral legs and reinforcing means in the interior of the shell. In one embodiment, the reinforcing means is a foam filling, which in a second embodiment, the reinforcing means comprises integral braces in the interior of the shell. A cap on the spool allows two or four spools to be banded together in a package assembly. The cap is also configured to permmit stacking of the spools.
摘要:
A method is provided for cabling a plurality of hardware components. A chassis controller establishes a wireless connection to a wireless device. The chassis controller, via a wireless interface, transmits a chassis map to the wireless device over the wireless connection. The chassis controller, via the wireless interface, transmits to the wireless device, an indication of a first port to be cabled over the wireless connection, the first port. The first port is of a first hardware component of the plurality of hardware components. The chassis controller tests the first port to determine whether cabling of the first port has been performed correctly.
摘要:
A method and system for personalizing a plurality of parts are disclosed. All of these parts have an identical part number and one or more programmable functions. The method comprises the steps of employing in a first product a first of said parts; and employing in a second product, a second of said parts. Prior to normal operation of the first product, a first code is set in the first part, and this first code causes the first part to provide a first programmable function during normal operation of the first product. Prior to normal operation of the second product, a second code is set in the second part, and this second code causes the second part to provide a second programmable function during normal operation of the second product. The said second programmable function is different from the first programmable function.
