2. What is an accurate statement concerning shared journals on node pairs?
A) Directly linked through mid-plane of the chassis
B) When a node boots, it first checks its paired node's resources
C) Nodes 1 and 3 and nodes 2 and 4 form node pairs
D) Requires a minimum of 4 nodes
3. Refer to the exhibit.
A large hospital chain has approached you to redesign their storage infrastructure. The head of IT believes their requirement is for 60 TB of RAW capacity. The following are the notes from meetings with the department heads.
