The command purearray phonehome --status provides the current status of Phonehome log transmissions, confirming whether logs have been successfully sent before an upgrade.

The command purehw list --all displays detailed hardware information, including NVRAM installation and update status on the FlashArray.

The FlashArray//X70R2 and //X90R2 models are equipped with dual 1600W power supplies, each rated for 1600 watts. These high-wattage power supplies are designed to support the increased performance and capacity demands of these models. The power supplies operate in an N+1 redundancy configuration, ensuring continuous operation even if one power supply fails.

When installing the first DirectFlash Shelf on a FlashArray//XR2/3, mezzanine ports ETH6 and ETH9 on the controllers are used for connectivity.

Customers can independently upgrade Purity using the Self-Service upgrade portal on Pure1 Manage, enabling them to proceed without waiting for support scheduling.

The command pureadm stop --controller CT0 specifically stops Purity on the designated controller (CT0), which is the correct step to safely begin a controller upgrade.

The FlashArray//X20R4 requires a minimum AC input voltage of 180V to operate. This ensures stable power delivery for the array's components.

On an XR2/3 array, a 4-port Fibre Channel card installed in slot 1 is assigned interface names FC4 through FC7, continuing the numbering sequence from other installed FC ports.

Fibre Channel (FC) I/O cards are compatible across all FlashArray models, providing consistent SAN connectivity regardless of array generation.
