What hardware should the Implementation Engineer find in the upgrade kit in order to perform...

For a Non-Disruptive Upgrade (NDU) from aFlashArray//Xto aFlashArray//XL, the upgrade kit typically contains4 QSFP cables, 2 Mellanox cards, and 20 DFMD blanks (or modules).

2 Mellanox Cards:The FlashArray//X (source) likely requires the installation of 100GbE RoCE adapters (Mellanox) into its controllers to establish the high-speed replication link with the new FlashArray//XL (which has 100GbE native). One card is installed per //X controller.

4 QSFP Cables:To ensure a redundant, high-bandwidth connection between the two arrays during the data migration phase, 2 cables are used per controller pair (CT0-to-CT0 and CT1-to-CT1), totaling 4 cables.

20 DFMDs (Blanks/Fillers):The FlashArray//X typically holds 20 DirectFlash Modules. The FlashArray//XL chassis has 40 slots. When the 20 data drives are physically moved from the //X to the //XL, the //XL will still have 20 empty slots. These must be filled with DirectFlash blanking modules (DFMD blanks) to maintain proper chassis airflow and thermal pressure. Thus, the kit includes these 20 fillers.
