Patent Searching and Data


Title:
DATA PROCESSING METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/090113
Kind Code:
A1
Abstract:
The invention relates to a data processing method and device, the method is applied to the data processing device which includes a control unit, a first nonvolatile storage unit and a second nonvolatile storage unit, and the rate of writing data of the first nonvolatile storage unit is higher than the rate of writing data of the second nonvolatile storage unit. The method includes: the control unit receiving a writing data request from a virtual machine, the writing data request including a first data; determining the log record of the first data; comparing the size of the log record of the first data with the remain space of the first nonvolatile storage unit, if the size of the log record of the first data is bigger than the remain space of the first nonvolatile storage unit, the control unit controlling the first nonvolatile storage unit to store the log record of the second data into the second nonvolatile storage unit to increase the remain space of the first nonvolatile storage unit. Therefore, the probability of failing to write data into the first nonvolatile storage unit is reduced.
