Computer system, server module, and storage module

A computer system comprising:

• a server module, which includes a first processor and a first memory and which handles data on a first data format basis,
• a storage module, which includes a second processor, a second memory and a storage device and which handles data on a second data format basis, the second data format including a data assurance code, and
• a transfer module, which executes a DMA transfer from the first memory in the server module to the second memory in the storage module, when the transfer module receives a write command from the first processor of the server module,
• the transfer module executes the DMA transfer by:
• reading a second data of the first data format, the second data including a particular data corresponding to the write command, from the first memory of the server module;
• adding the data assurance code for the particular data to the second data to convert the second data from the first data format to the second data format;
• and
• writing the converted second data to the second memory.

A transfer module being adapted to be coupled to a server module and a storage module, the server module including a first processor and a first memory and handling data on a first data format basis, the storage module including a second processor, a second memory and a storage device and handling data on a second data format basis, the second data format including a data assurance code, the transfer module executes a DMA transfer from the second memory in the storage module to the first memory in the server module, when the transfer module receives a read command from the first processor of the server module,

• the transfer module executes the DMA transfer by:
• reading a first data of the second data format, the first data including a particular data corresponding to the read command and a first data assurance code for the particular data, from the second memory of the storage module;
• checking the particular data based on the first assurance code in the first data;
• removing the first assurance code from the first data to convert the first data from the second data format to the first data format;
• and
• writing the converted first data to the first memory.
