  • Storage system architecture with dual storage virtualization controllers and the data access method thereof
    Patent number: 11842083
    Abstract: In a storage system architecture having two storage virtualization controllers (SVCs) that operate in an active-active mode, the corresponding relationships between storage addresses in the two buffers of the two SVCs are pre-determined. When a non-owner SVC that does not have an ownership over a logical disk (LD), receives an I/O request from a host, the non-owner SVC will inquire of the other SVC having the ownership, about associated address information, and then the non-owner SVC that does not have the ownership over the LD will perform, according to the associated address information, the I/O request from the host. Therefore, data synchronization operation for mutually backing up data between the two SVCs can be fast achieved. Also, it allows the host to issue a data access request to any one of the SVCs, thus improving performance of the storage system.
