Abstract
According to one embodiment, a video distribution server includes an SSD and an SSD operator. The SSD includes a storage medium and a controller. The controller executes a wear leveling process on the storage medium. The SSD operator gives the controller an instruction to disable a wear leveling function. The wear leveling function provides the wear leveling process.
Claims15
A video distribution server comprising:
- a Solid State Drive (SSD) comprising:
- a storage medium;
- and
- a controller configured to execute a wear leveling process on the storage medium;
- and
- an SSD operator configured to give the controller an instruction to disable a wear leveling function, the wear leveling function providing the wear leveling process.
An SSD control method used in a video distribution server comprising a plurality of Solid State Drives (SSDs) each comprising a storage medium and a controller configured to execute a wear leveling process on the storage medium,
- wherein the plurality of SSDs store, in the respective storage media, a plurality of divided data into which material data is divided and redundant data intended to restore one of the plurality of divided data, and the method comprises:
- acquiring a number of sessions per preset period;
- determining a current state to be a first state when the number of sessions in a current period is larger than a preset reference value;
- in the first state, giving the controllers mounted in the plurality of SSDs an instruction to disable a wear leveling function to execute the wear leveling process and to enable a reading function to read the divided data and/or redundant data from the storage medium;
- determining the current state to be a second state when the number of sessions during the current period is not larger than the preset reference value,
- in the second state, giving the controllers mounted in a certain number of the plurality of SSDs an instruction to disable the wear leveling function and to enable the reading function and giving the controllers mounted in the other SSDs of the plurality of SSDs an instruction to enable the wear leveling function and to disable the reading function;
- and
- reading the divided data and/or redundant data from the storage medium in the SSD, the SSD included in the plurality of SSDs and for which the wear leveling function is disabled, whereas the reading function is enabled.
