Abstract
A data storage device array includes a number of data storage devices. Each of the disc drives is operable to spin-up its spindle motor in response to the successful communication of predetermined out-of-band (OOB) signals. By selectively causing the communication of the predetermined OOB signals to the data storage devices, the selective spin-up of the data storage devices may be achieved.
Claims26
A system for selectively controlling spin-up times of data storage devices in an array of data storage devices, comprising:
- a plurality of data storage devices, each data storage device spinning-up in response to the successful communication of predetermined out-of-band (OOB) signals;
- a plurality of port controllers, each port controller being associated with one or more of the plurality of data storage devices, each port controller communicating the predetermined OOB signals to its associated data storage device or devices upon receiving a predetermined start signal;
- and
- a timing controller operable to selectively communicate the predetermined start signal to one or more of the plurality of port controllers.
A method of spinning-up a spindle motor in a data storage device, comprising steps of:
- communicating a predetermined sequence of out-of-band (OOB) signals to the data storage device;
- and
- responsive to the successful communication of the predetermined sequence of OOB signals, spinning-up the spindle motor in the data storage device.
A system for selectively controlling spin-up times in an array of data storage devices, comprising:
- a plurality of data storage devices, each data storage device including a spindle motor, each data storage device causing the spin-up of its spindle motor in response to the successful communication of a predetermined sequence of OOB signals with the data storage device;
- and
- a control means operable to selectively cause the communication of the predetermined out-of-band (OOB) signals with the data storage devices.
