==STORAGE DEVICE POOL MANAGEMENT BASED ON FRAGMENTATION LEVELS - A simplified explanation of the abstract==


This abstract first appeared for US patent application 17851595 titled 'STORAGE DEVICE POOL MANAGEMENT BASED ON FRAGMENTATION LEVELS

==Simplified Explanation==

The patent application describes aspects related to data storage management. Here is a simplified explanation of the abstract:

* The data storage system receives information about the fragmentation level of data storage devices and data from a host device that needs to be stored.
* Based on the fragmentation level information, a target data storage device is selected, and the host data is sent to that device.
* The data storage device itself determines threshold conditions that trigger a defragmentation process.
* A fragmentation level metric is calculated by the data storage device, indicating how close it is to initiating the defragmentation process.
* This fragmentation level metric is then sent to a storage management device for further action.

Potential Applications:

* This technology can be applied in various data storage systems, such as computer hard drives, solid-state drives (SSDs), and network-attached storage (NAS) devices.
* It can be used in cloud storage systems to optimize data placement and improve overall system performance.

Problems Solved:

* Fragmentation in data storage devices can lead to decreased performance and increased access times.
* This technology helps in managing fragmentation by selecting the most suitable storage device and triggering defragmentation processes when necessary.

Benefits:

* By selecting the target data storage device based on fragmentation level information, the system can distribute data more efficiently and improve overall performance.
* The ability of the data storage device to determine threshold conditions for defragmentation helps in maintaining optimal storage performance.
* The fragmentation level metric provides valuable information to the storage management device, enabling proactive maintenance and optimization of the storage system.


==Original Abstract Submitted==

Aspects directed towards data storage management are provided. In one aspect, a data storage system receives fragmentation level information from data storage devices, and host data from a host device to be stored in the data storage devices. Based on the received fragmentation level information, a target data storage device is selected from the data storage devices, and the host data is sent to the target data storage device. In another aspect, a data storage device determines threshold conditions that trigger a defragmentation process. For this aspect, a fragmentation level metric indicating a proximity of the data storage device to initiating the defragmentation process is calculated based on the threshold conditions and a current amount of data stored in a non-volatile memory (NVM). The fragmentation level metric is then sent to a storage management device.
