[1] Self-encrypting HDDs adhere to standards such as AES-256, and FIPS 140-2.

[2] A "pure" SSD shelf contains SSDs only; a "mixed" shelf contains a combination of SSDs and HDDs for use by Flash Pool. Flash Pool also works in "shelf-to-shelf" configurations in which SSDs from a pure SSD shelf are combined into an aggregate with HDDs from other shelves.

[3] The DS4243 disk shelf is no longer available in new system shipments but will remain available as add-on storage. PDF.
