Method relating to configurable storage device and adaptive storage device array

摘要

An array can include a controller and multiple storage devices of a first type. When a storage device of the first type is replaced by a replacement storage device of a second type, and other storage devices of the first type remain in the array, the controller instructs the replacement storage device to configure itself as a storage device of the first type. When the last storage device of the first type in the array is replaced by a replacement storage device of the second type, the controller instructs all the storage devices of the array to configure themselves as storage devices of the second type.

主权项

1. A method comprising:
responsive to a storage device of a first type currently connected to a backplane of an array connected to a plurality of storage devices including the storage device of the first type having been replaced by a replacement storage device of a second type, each of the type and the second type includes a storage device performance, a storage device manufacturer, and a storage device model, performing:
determining, by a controller of the array connected to the backplane to communicate with the storage devices connected to the backplane, whether any other storage device currently connected to the backplane is of the first type; andin response to the controller determining that any other storage device currently connected to the backplane is of the first type, sending by the controller to the replacement storage device an instruction to configure itself as a storage device having the storage device performance, the storage device manufacturer, and the storage device model of the first type, wherein responsive to receiving the instruction from the controller, the replacement storage device configures itself as the storage device having the storage device performance, the storage device manufacturer, and the storage device model of the first type.
