Abstract
According to some embodiment, a backup storage system receives a request from a client for writing a data segment associated with a file object stored to a storage system. In response to the request, the system writes the data segment to one of a plurality of storage units of the storage system. The system determines whether an amount of access to a solid state device (SSD) operating as a cache memory device exceeds an access threshold based on a time window distribution. The system throttles access to the SSD for caching data in response to determining that the amount of access to the SSD has exceeded the access threshold.
