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.
Claims16
A video distribution server comprising:
- a plurality of Solid State Drive (SSD) each comprising:
- a storage medium configured to record a plurality of divided data into which content data is divided and redundant data intended to restore one of the plurality of divided data;
- and
- a controller configured to execute a wear leveling process on the storage medium;
- and
- a RAID (Redundant Arrays of Inexpensive Disks) controller configured:
- to acquire a number of sessions per preset period, a session being established between a communication terminal and the video distribution server, wherein the session starts when the video distribution server accepts a request from the communication terminal for accessing the video distribution server;
- to determine whether the number of sessions is larger than a preset reference value or not;
- and
- to give the controllers mounted in the plurality of SSDs an instruction to enable a wear leveling function providing the wear leveling process and to disable a reading function to read the divided data and/or the redundant data from the storage medium, or an instruction to disable the wear leveling function and to enable the reading function based on a result of the determination.
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 content 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, a session being established between a communication terminal and the video distribution server, wherein the session starts when the video distribution server accepts a request from the communication terminal for accessing the video distribution server;
- determining whether the number of sessions is larger than a preset reference value or not;
- giving the controllers mounted in the plurality of SSDs an instruction to enable a wear leveling function to execute the wear leveling process and to disable a reading function to read the divided data and/or redundant data from the storage medium, or an instruction to disable the wear leveling function and to enable the reading function based on a result of the determination.
