Abstract
Aspects of the invention include receiving an input/output (I/O) request that includes a data stream from a host processor. The receiving is at a network adapter of a storage controller that manages storage for the host processor. The storage controller includes a storage buffer to store data received from the host processor before migrating it to the storage. The storage controller also includes a data cache. It is determined whether the storage buffer has enough free space to store the received data stream. Based at least in part on determining that the storage buffer has enough free space to store the received data stream, the received data stream is stored by the network adapter in the storage. Based at least in part on determining that the storage buffer does not have enough free space to store the received data stream, the received data stream is stored in the data cache.
