  • Management of block storage devices based on access frequency wherein migration of block is based on maximum and minimum heat values of data structure that maps heat values to block identifiers, said block identifiers are also mapped to said heat values in first data structure
    Patent number: 10740016
    Abstract: A system, method, and computer program product are provided for allocating blocks of memory in a virtual storage device based on access frequency. The method includes the steps of tracking access frequency for a plurality of blocks of memory in a virtual storage device utilizing a heat map and reallocating the plurality of blocks of memory in the virtual storage device among a plurality of blocks of memory in two or more real storage devices based on the heat map. The heat map includes at least one data structure that maps block identifiers corresponding to the plurality of blocks of memory in the virtual storage device to heat values that represent the access frequency of a corresponding block of memory.

  • Placement engine for a block device
    Patent number: 9740627
    Abstract: A system, method, and computer program product are provided for implementing a reliable placement engine for a block device. The method includes the steps of tracking one or more parameters associated with a plurality of real storage devices (RSDs), generating a plurality of RSD objects in a memory associated with a first node, generating a virtual storage device (VSD) object in the memory, and selecting one or more RSD objects in the plurality of RSD objects based on the one or more parameters. Each RSD object corresponds to a particular RSD in the plurality of RSDs. The method also includes the step of, for each RSD object in the one or more RSD objects, allocating a block of memory in the RSD associated with the RSD object to store data corresponding to a first block of memory associated with the VSD object.
