Which two statements are correct when adding cache to a VSP E590? (Choose two.)

Question

Options

• ACache modules must be installed in CMG1.
• BCache Modules must be installed on the CM board.
• CCMG0 and CMG1 must have the same DIMM type.
• DThis is not supported online.

• A
  15% (4)
• B
  81% (21)
• D
  4% (1)

Explanation

Cache Modules on the VSP E590 are physically seated on the CM (Controller Module) board itself - not in a separate external enclosure - making B correct. Additionally, both CMG0 and CMG1 must use identical DIMM types to maintain cache symmetry and ensure proper mirroring between the two cache module groups, making C correct.

Why the distractors are wrong: Option A is a trap - there is no rule mandating cache be installed exclusively in CMG1; both CMGs must be configured symmetrically. Option D is incorrect because cache expansion on the VSP E590 is a non-disruptive, online operation - you do not need to take the system offline.

Memory tip: Think "Board + Balance" - cache goes on the CM Board (B), and both CMGs must be Balanced with the same DIMM type (C). If you remember those two Bs, you lock in the correct answers.
