Abstract
A computer system 100 that allows a storage facility 500 to be shared by multiple different users of an Infrastructure as a Services (IaaS) system while maintaining security separation between the users is provided. A controller 150 configured for use in the computer system and a corresponding method and computer program are also provided. The computer system 100 comprises a logic block 101 that comprises one or more processing units that execute instructions, the logic block 101 configured to issue requests to read from and write to storage over a first interface 102; and a controller 150 that is configured to implement a communications link to storage 500; implement a communications link 300 to a second computer system 200 and to receive information identifying a current user of the logic block 101 from the second computer system 200; and receive the requests to read from and write to storage from the logic block 101 over the first interface 102, and to complete the requests. The first interface 102 is a dedicated physical interface between the logic block 101 and the controller 150, whereby the controller 150 can determine that communications over the first interface 102 are com…
