  • Patent number: 11809293
    Abstract: The present invention provides a control method of a server, wherein the control method includes the steps of: periodically controlling a first register and a second register of a first node to have a first value and a second value, respectively; periodically controlling a third register and a fourth register of a second node to have a third value and a fourth value, respectively; controlling the first register and the fourth register to synchronize with each other, wherein the first value is different from the fourth value; controlling the second register and the third register to synchronize with each other, wherein the second value is different from the third value; and periodically checking if the third register has the third value and the fourth register has the fourth value to determine if the first node fails to work.

  • Patent number: 11366618
    Abstract: The present invention provides a control method of a server, wherein the control method includes the steps of: setting a first node within the server as a master device; setting a second node within the server as a slave device; controlling the first node to receive data from another device via network; storing the data into a first write buffer within the first node; performing a cache mirroring operation to copy the data stored in the first write buffer into a second write buffer within the second node; setting a first tail register and a first head register within the first node, and setting a second tail register and a second head register within the second node; and referring to the first tail register and the first head register to determine if the data stored in the first write buffer is successful written into the second write buffer.

  • Patent number: 10324786
    Abstract: A method for managing data stored in a flash memory is provided, where the flash memory includes a plurality of blocks. The method includes: providing a program list, where the program list records information about programmed blocks of the plurality of blocks and sequence of write times of the programmed blocks; detecting quality of a first block of the plurality of blocks to generate a detecting result, where the first block is the programmed block that has an earliest write time; and determining whether to move contents of the first block to a blank block, and to delete the contents of the first block according to the detecting result.
