Methods and apparatus to manage transmissions between domains and memory

An apparatus comprising:

• memory;
• a first domain having a first classification, the first domain conductively coupled to the memory, the first domain including:
• a first bus adapter to conductively couple the first domain to the memory, the first bus adapter enabling transmission of first data from the first domain to the memory, the first data associated with the first domain, and the first bus adapter being a first host bus adapter (HBA) serial attached small computer system interface (SCSI) (SAS) card;
• and
• a first expander to facilitate the transmission of the first data to the memory, the memory to store the first data;
• and
• a second domain conductively coupled to the memory, the second domain having a second classification different from the first classification, the second domain including:
• a second bus adapter to conductively couple the second domain to the memory, the second bus adapter enabling access of the first data from the memory by the second domain, the second bus adapter preventing second data from exiting the second domain, the second data associated with the second domain, the second bus adapter being a second HBA SAS card, and the second HBA SAS card being write-block enabled;
• and
• a second expander to facilitate the access of the first data from the memory.
