1. A server, comprising:
a solid state drive (SSD);
a first node, comprising:
a first memory, comprising a first register and a second register;
a first processor, configured to control the first register and the second register to have a first value and a second value, respectively; and
a first communication circuit, coupled to the first processor and the first memory; and
a second node, comprising:
a second memory, comprising a third register and a fourth register;
a second processor, configured to control the third register and the fourth register to have a third value and a fourth value, respectively; and
a second communication circuit, coupled to the second processor, the second memory and the first communication circuit;
wherein the first register and the fourth register are synchronized with each other, the second register and the third register are synchronized with each other, the first value controlled by the first processor is different from the fourth value controlled by the second processor, and the second value controlled by the first processor is different from the third value controlled by the second processor.
