Abstract
It is an objective to diminish time required to read or write divided data. An information processing equipment that can be connected to a storage includes a division processing section for dividing original data into a plurality of sets of divided data and a storage location selection section that selects either the storage or a storage section of the information processing equipment as a divided data storage location and that stores the divided data into the selected storage location, wherein the division processing section determines a division ratio of divided data according to a data reading rate and/or a data writing rate of the storage location selected by the storage location selection section.
Claims18
An information processing equipment capable of being connected to an external storage comprising:
- a division processor configured to divide original data into a plurality of sets of divided data;
- an internal storage configured to store the divided data;
- a storage location selector configured to select the external storage and the internal storage as storage locations for the plurality of sets of divided data and to store the divided data into the selected storage locations;
- and
- a rate measurer configured to write predetermined data in each of the storage locations and to measure a data reading rate and/or a data writing rate of the storage location on the basis of the time required to read and/or write the predetermined data, wherein:
- the division processor is configured to determine a division ratio of divided data between the external storage and the internal storage according to a data reading rate and/or a data writing rate of the storage locations selected by the storage location selector, and
- wherein the division processor is configured to divide the original data into divided pieces, a number of which is equal to a total number of division ratio, and to distribute the divided pieces according to the division ratio, thereby creating the divided data.
An information processing equipment capable of being connected to an external storage comprising:
- a division processor configured to divide original data into a plurality of sets of divided data;
- an internal storage configured to store the divided data;
- and
- a storage location selector configured to select the external storage and the internal storage as storage locations for the plurality of sets of divided data and to store the divided data into the selected storage locations, wherein:
- the division processor is configured to determine a division ratio of divided data between the external storage and the internal storage according to a data reading rate and/or a data writing rate of the storage locations selected by the storage location selector,
- wherein the division processor is configured to divide the original data into divided pieces, a number of which is equal to a total number of division ratio, and to distribute the divided pieces according to the division ratio, thereby creating the divided data,and
- predetermined data are written into each of the storage locations by use of DMA transfer, and a data reading rate and/or a data writing rate of the storage locations is measured on the basis of time required to read and/or write the predetermined data.
An information processing equipment capable of being connected to an external storage comprising:
- a division processor configured to divide original data into a plurality of sets of divided data;
- an internal storage configured to store the divided data;
- and
- a storage location selector configured to select the external storage and the internal storage as storage locations for the plurality of sets of divided data and to store the divided data into the selected storage locations, wherein:
- the division processor is configured to determine a division ratio of divided data between the external storage and the internal storage according to a data reading rate and/or a data writing rate of the storage locations selected by the storage location selector,
- wherein the division processor is configured to divide the original data into divided pieces, a number of which is equal to a total number of division ratio, and to distribute the divided pieces according to the division ratio, thereby creating the divided data, and
- the data reading rate and/or the data writing rate for the storage locations, whichever corresponds to a maximum value, a minimum value, an average value, and a latest value of the reading rate and/or the writing rate, is acknowledged to the division processor, and
- the division processor is configured to create divided data by use of the acknowledged reading rate and/or writing rate.
