    摘要: A method and apparatus is provided that provides a reliable diskless network-bootable computers using a local non-volatile memory (NVM) cache. The NVM cache is used by the computer when the network is temporarily unavailable or slow. The cache is later synchronized with a remote boot server having remote storage volumes when network conditions improve. It is determined if data is to be stored in the NVM cache or the remote storage volume. Data sent to the remote storage volume is transactionally written and the data is cached in the NVM cache if a network outage is occurring or a transaction complete message has not been received. The data stored in the NVM cache allows the user to continue operating during network outages and the computer can be cold-booted using the data in the NVM cache if the network is unavailable.

    摘要: A method of preventing data loss in a data storage system includes supplying write data to a high speed volatile write buffer and supplying electrical power from an energy storage device upon detection of a primary power loss event. The backup electrical power is supplied to the write buffer and nonvolatile cache. Under backup power, the write data is transferred into the nonvolatile cache and the backup power is removed. Upon regaining main power, a data presence indication triggers a transfer of the write data from the nonvolatile cache to the long term storage media. The method may be implemented for a system to protect it from inadvertent power losses or it may implemented in a system where the long term storage device is power cycled to save power. The energy storage device is not necessarily needed in the power cycled system unless power failure protection is also desired.
