An HPE Alletra 6030 with 138TB flash kit needs a storage expansion.

Detailed Explanation:

Rationale for Correct Answer:

Alletra 6000 expansion shelves connect via 24G SAS back-end connectivity. The BOM must include the required SAS cables to properly attach the shelf. If only the shelf is listed, it’s incomplete — SAS connectivity accessories must be added.

Distractors:

B: The supported max capacity is higher than 138TB + 46TB, so it won’t exceed limits.

C: Expansion shelves don’t use OCP adapters; they rely on SAS backend ports.

D: QSFP+ DACs are used for front-end networking (iSCSI/FC), not SAS shelf expansion.

Key Concept: Alletra 6000 expansions require 24G SAS cables included in the BOM.
