Storage system architecture with dual storage virtualization controllers and data access method
By Francis Pelletier | January 8, 2024 at 2:00 pmInfortrend Technology, Inc., New Taipei, Taiwan, has been assigned a patent (11842083) developed by Lo, Yun-Jian, New Taipei, Taiwan, for “storage system architecture with dual storage virtualization controllers and the data access method thereof.“
The abstract of the patent published by the U.S. Patent and Trademark Office states: “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.”
The patent application was filed on 2022-01-25 (17/584360).
