ABSTRACT:
One aspect of the invention is a method for configuring an array of storage devices to reduce the probability of data loss due to clustered storage device failures in the array. An example of this method includes identifying all storage devices in a primary set of storage devices and a first mirror set of storage devices in the array of storage devices. This example also includes obtaining data regarding each identified storage device. This example further includes determining if any of the storage devices in the primary set of storage devices has a vital characteristic that is the same as a vital characteristic of any of the storage devices in the first mirror set of storage devices, and if so, indicating an array configuration error, and if not, continuing the configuration.
