Abstract

See full text

An allocation instruction is received that includes a target data operand and a storage medium operand indicating a storage medium for storing the target data. A data dependency is identified that specifies metadata that includes access control information specifying which users have permission to perform a write operation to the file that includes the target data. In response to determining that the allocation instruction allocates the target data from a first storage medium to a second storage medium having a faster data IO rate, the allocation instruction is modified to also allocate the metadata specified in the data dependency to the second storage medium. In another aspect, the allocation instruction is modified to also allocate the metadata identified in the data dependencies to one or more storage mediums with data IO rates that are at least as fast as the second storage medium.
