Pass the Pure Storage FAIS FlashArray-Implementation-Specialist Questions and answers with ValidTests

The Ethernet mezzanine on FlashArray//XR2/3 is assigned interfaces starting at ETH8 through ETH11, reflecting the numbering scheme for additional Ethernet ports beyond the base interfaces.

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

The puredrive list --pack command shows detailed information about the specified data pack, including whether its drives are part of a wide write group.

To ensure compatibility and optimal performance, the Implementation Engineer should consult the recommended DFS versions for the installed Purity release and upgrade both the FlashArray and DirectFlash Shelf accordingly.

To upgrade from Purity 5.3.8 to 6.1.21 on a new array, the Implementation Engineer should create a bootable USB installer from the target ISO and reimage both controllers to ensure a clean and supported upgrade.

The command purehost monitor --balance checks the distribution and health of I/O across hosts and initiators, helping verify balanced I/O after a controller upgrade.

The correct consolidation process involves evacuating data from the existing chassis drives first, then installing the new larger 91TB data pack, and finally evacuating shelf 0 to complete the consolidation efficiently.

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.

Running cobalt_check.py on a new //XR4 array verifies hardware and system readiness before executing puresetup newarray, ensuring a smooth setup process.

To expand capacity from 5/5 to 11/11 packs, a swing shelf with temporary loan capacity is needed to safely evacuate data during the upgrade without risking data availability.
