Abstract
According to some embodiments, a backup storage system receives a request from a client at a storage system for accessing data segments. For each of a first groups of the data segments requested that are stored in a solid state device (SSD) cache, the system requests a first batch job for each of the first groups to retrieve the first groups of the data segments from the SSD cache via a first set of input/output (IO) threads. For each of a second groups of the data segments requested that are not stored in the SSD cache, the system requests a second batch job for each of the second groups to retrieve the second groups of the data segments from storage units of the storage system via a second set of input/output (IO) threads. The system assembles received segments and returns them to the client altogether.
