A computing system includes a volatile memory, a cache coupled with the volatile memory, and a processing device coupled with the cache and at least one of a storage device or a network port. The processing device is to: generate a plurality of virtual addresses that are sequentially numbered for data that is to be at least one of processed or transferred in response to an input/output (I/O) request; allocate, for the data, a continuous range of physical addresses of the volatile memory; generate a set of hash-based values based on mappings between the plurality of virtual addresses and respective physical addresses of the continuous range of physical addresses; identify a unique cache line of the cache that corresponds to each respective hashed-based value of the set of hash-based values; and cause the data to be directly stored in the unique cache lines of the cache.
