Method Apparatus and System for a Redundant and Fault Tolerant Solid State Disk |
摘要 |
A redundant and fault tolerant solid state disk (SSDC) includes a determination module configured to identify a first SSDC configured to connect to a flash array and a second SSDC configured to connect to the flash array. A capture module is configured to capture a copy of an I/O request received by the first SSDC from a port of a dual port connector, and/or capture a copy of an I/O request received by the second SSDC from a port of the dual port connector, and identify a write I/O request from the I/O request. A detection module is configured to detect a failure in the first SSDC. A management module is configured to manage access to a flash array by the first SSDC and the second SSDC. An error recovery and failover module is configured to automatically reassign work from the first SSDC to the second SSDC.
