The amount of buffer space available for requests coming in to the Secondary over the network is determined by the Veritas Volume Replicator (VVR) tunable, vol_max_nmpool_sz, which defaults to 16 megabytes. VVR allocates separate buffer space for each Secondary RVG, the size of which is equal to the value of the tunable vol_max_nmpool_sz. The buffer space on the Secondary must be large enough to prevent slowing the network transfers excessively. If the buffer space on the Secondary is too small, the replicated data is discarded and memory errors are returned back to the Primary.
