Techniques involve obtaining, at a first network interface card coupled with a first device, information related to a plurality of data blocks to be written to a second device, the information including sizes of the plurality of data blocks and a plurality of destination addresses in a memory of the second device where the plurality of data blocks will be written. The techniques further involve generating a write request for the plurality of data blocks based on the information, the write request indicating at least the plurality of destination addresses and the sizes of the plurality of data blocks. The techniques further involve sending the write request to a second network interface card coupled with the second device, so that the plurality of data blocks are written to the plurality of destination addresses. Such techniques reduce the number of communications thus improving system performance and reducing hardware resource consumption.

Techniques for accessing a storage system involve: based on a detection that a first host configured to use a first protocol to access a storage system is connected to the storage system, determining a source logical storage space from a second group of logical storage spaces associated with a second protocol. The second protocol is different from the first protocol. The techniques further involve: determining, from a first group of logical storage spaces associated with the first protocol, a target logical storage space to which the source logical storage space is mapped. The techniques further involve: allocating the target logical storage space to the first host, so that the first host accesses the storage system via the target logical storage space. Accordingly, suitable protocols can be flexibly used to access the storage system without cumbersome and time-consuming operations.
