• Question 21:

  Which of the following statements about the Global Cache technology employed by the WushanFS are correct? (Select three.)

  A. Global Cache enables the memory space on all storage servers to form a unified memory resources pool logically.
  B. Data cached on a node cannot be hit by the read/write service of another node.
  C. Global Cache helps improve the sharing of memory resources among nodes.
  D. The WushanFS uses the distributed lock mechanism to implement global management of cached data. The same service data is cached only on one node. Another node that needs to access the service data can apply for a lock to obtain the cached data.
