Abstract
A control device for controlling a storage device in which data is stored, the control device includes a processor that sets protection condition of the storage device through a signal line coupled with the storage device and sets the protection condition of the storage device through a first transmission line coupled with the control device, and an exchange switch coupled with the control device and an arithmetic operation device through the first transmission line and a second transmission line, respectively, the exchange switch being configured to switch between the first transmission line and the second transmission line so as to communicably couple either one of the control device and the arithmetic operation device with the storage device.

A control device for controlling a storage device in which data is stored, the control device comprising:
- a processor that sets protection condition of the storage device through a signal line coupled with the storage device and sets the protection condition of the storage device through a first transmission line coupled with the control device, and
- an exchange switch coupled with the control device and an arithmetic operation device through the first transmission line and a second transmission line, respectively, the exchange switch being configured to switch between the first transmission line and the second transmission line so as to communicably couple either one of the control device and the arithmetic operation device with the storage device.
A control device method that controls a storage device, comprising:
- setting protection condition of the storage device through a signal line coupled with the storage device and the protection condition of the storage device through a first transmission line coupled with the control device;
- and
- switching between the first transmission line and the second transmission line so as to communicably couple either one of the control device and the arithmetic operation device with the storage device.
