摘要： Various aspects for managing input/output (I/O) operations for data objects (e.g., large data objects (LOBs)), in a storage system are provided. For instance, a method may include receiving an I/O request for executing an I/O operation on a data object, determining the size of the data object, and determining the data object to be a non-conforming data object relative to a storage threshold of a cache memory device. The method may further include dividing the non-conforming data object into multiple data chunks, each of the data chunks having a size that is less than the storage threshold, moving one or more data chunks stored in one or more memory spaces of the cache memory device to a long-term memory device to free up the one or more memory spaces, and storing one or more of the data chunks of the non-conforming data object in the freed-up memory space(s).
