On a local data storage system, a single buffer of contiguous local memory is allocated to store host data from multiple received host data buffers in a local cache, and local internal data processing operations may be performed on the host data with local data processing resources using the single buffer of contiguous local memory in the local memory to store the host data. On a remote data storage system onto which the host data is replicated, a single buffer of contiguous remote memory is allocated to store host data from multiple transmission units used to convey the host data to the remote data storage system, and remote internal data processing operations may be performed on the host data by one or more remote data processing resources using the single buffer of contiguous remote memory to store the host data from the received transmission units.

Host data replication allocating single memory buffers to store multiple buffers of received host data and to internally process the received host data

Transferring data elements from a source to a destination includes providing a transmission queue at the source, where data elements in the transmission queue are transferred from the source to the destination, determining an optimal length for the transmission queue, where the optimal queue length is inversely proportional data latency time at the destination, and, if the optimal length is greater than an instantaneous length of the transmission queue, adding data elements to the transmission queue. Adding data elements may include adding a number of elements corresponding to a difference between the optimal length and the instantaneous length of the transmission queue. Determining optimal length may include dividing a constant by the data latency time at the destination. Transferring data elements may also include providing a network between the source and the destination.
