    • A computer program product includes a computer readable storage medium having program instructions embodied therewith, wherein the program instructions are executable by a processor to cause the processor to perform a method. The method includes storing an operating system in minor stripes on a first data storage device forming a first logical storage unit, and storing data in major stripes across a plurality of data storage devices forming a second logical data storage unit. Each major stripe includes a plurality of minor stripes storing data and a parity stripe. The method further includes calculating the parity stripe from the plurality of minor stripes within the major stripe and a corresponding one of the minor stripes on the first data storage device, wherein the minor stripes on the first data storage device match the size of the minor stripes on the array of data storage devices.

    • A computer program product includes a computer readable storage medium having program instructions executable by a processor to cause the processor to perform a method. The method includes a compute node sensing the operating environment around the compute node during setup and storing the operating environment sensed during setup as the predetermined operating environment. The method further includes the compute node tracking data stored by the compute node while the compute node is located within the predetermined operating environment, sensing a current operating environment of the computer system after setup and after data has been stored, and determining whether the current operating environment is the same as the predetermined operating environment. The compute node may then wipe the data stored by the compute node while the compute node was located within the predetermined operating environment in response to determining that the current operating environment has changed.
    • 计算机程序产品包括具有可由处理器执行以使处理器执行方法的程序指令的计算机可读存储介质。 该方法包括计算节点,其在建立期间感测计算节点周围的操作环境,并将设置期间感测的操作环境存储为预定的操作环境。 该方法还包括计算节点在计算节点位于预定操作环境内时跟踪由计算节点存储的数据,在设置之后和数据已被存储之后感测计算机系统的当前操作环境,以及确定当前操作 环境与预定的操作环境相同。 响应于确定当前操作环境已经改变,计算节点可以在计算节点位于预定操作环境内时擦除计算节点存储的数据。
