How many power connections are required for the FlashArray//XL chassis?

The FlashArray//XL is a high-performance, 5U storage system designed for massive scale and throughput. To support its powerful processors and high-density DirectFlash modules, the chassis is equipped withfourPower Supply Units (PSUs).

Consequently, the installation requires4 power connections. Each PSU must be connected to a power source to ensure full redundancy and load sharing. Best practice dictates distributing these four connections across two independent Power Distribution Units (PDUs) (e.g., PSUs 1 & 3 to PDU A, PSUs 2 & 4 to PDU B) to survive the loss of a single power feed or PDU failure without interrupting array operations.

This is a key differentiator from the smaller 3U FlashArray//X models, which typically require only two power connections (one per PSU). Implementation Engineers must ensure that the rack has sufficient outlets (4 for the //XL chassis alone, plus additional outlets for any shelves) before beginning the physical installation.
