Abstract
Method and system for data migration between data generating entities and data storage devices protected by de-clustered RAID algorithm are enhanced by dynamically controlling the I/O activity towards the data storage devices (NVM devices) based on their remaining lifespan (health) with the goal to prevent multiple devices selected for writing a parity stripe information from simultaneous failures. This feature is rendered by polling the remaining health of NVM devices in the RAID pool, computing a weighted lifespan for each NVM device, comparing the latter to an average of all NVM devices in the pool, and adjusting the I/O activity towards the NVM device of interest accordingly. If the weighted lifespan exceeds the average lifespan in the pool, the allowed I/O activity is increased, and if the weighted lifespan is below the average for the pool, then the device in question is sent less “writes”.
