Abstract: A method and system of determining the execution point of programs executed in lock step. At least some of the illustrative embodiments are computer systems comprising a first processor that executes a program, and a second processor that executes a duplicate copy of the program in lock step with the first processor. After receipt of a duplicate copy of an interrupt request by each processor, the first processor determines the execution point in its program relative to the execution point of the duplicate copy of the program executed by the second processor.

Abstract: Storage media is coupled to first and second storage controllers. When the first storage controller performs encryption key rotation, the first storage controller writes a key rotation message to a storage controller metadata section of the storage media indicating that key rotation is underway. The second storage controller observes the key rotation message indicating that key rotation is underway and suspends access by the second storage controller to encrypted portions of the storage media.
Abstract translation: 存储介质耦合到第一和第二存储控制器。 当第一存储控制器执行加密密钥旋转时，第一存储控制器将密钥旋转消息写入存储介质的存储控制器元数据部分，指示密钥旋转正在进行。 第二存储控制器观察到键旋转消息，指示键旋转正在进行，并且暂停第二存储控制器对存储介质的加密部分的访问。

Abstract: A method and system of executing duplicate copies of a program in lock step. Some illustrative embodiments are a computer system comprising a first processor executing a program, a second processor executing a duplicate copy of the program (the first processor and second processor executing their respective programs in lock step), a logic device coupled to the processors, and a shared device coupled to the processors through the logic device. The first processor presents to the logic device a first operation involving the shared device, and the second processor does not present an operation, or presents an operation that does not match the first operation. The logic device obtains a second operation from the second processor that matches the first operation, and wherein a single operation that matches the first and second operations is presented to the shared device.
