  • Dynamic I/O throttling in a storlet environment
    Patent number: 10585596
    Abstract: A method, computer system, and a computer program product for dynamic IO throttling in a storlet environment is provided. The present invention may include receiving, from a user, a computational algorithm. The present invention may also include deploying the received computational algorithm. The present invention may then include determining the user has not engaged throttling based on the deployed computational algorithm. The present invention may further include parsing the computational algorithm based on the engaged throttling. The present invention may include identifying a pipeline operation based on the parsed computational algorithm. The present invention may also include building a timing relation between the identified pipeline operation and an IO operation. The present invention may then include translating a timing lag to a storage IO operation based on the built timing relation.

  • Allocation of heat-tiered storage among throttling units
    Patent number: 10552051
    Abstract: A data storage system has multiple tiers of data storage including an upper tier having a lower access latency and a lower tier having a higher access latency. A storage controller of the data storage system implements throttling limits regulating access to data in the data storage system for a plurality of throttling units sharing the data storage system. The storage controller also tracks access frequencies of extents in the data storage system. The storage controller migrates extents among the multiple tiers based on the access frequencies of the extents and the throttling limits implemented for the throttling units.
