NEW QUESTION # 145
How many power connections are required for the FlashArray//XL chassis?
Answer: B
Explanation:
Understanding the physical power requirements of the Pure Storage FlashArray//XL is critical during the site planning and rack-and-stack phases of an installation. Unlike the standard 3U FlashArray//X or //C models, which operate on two power supplies (one per controller for standard 1+1 redundancy), the FlashArray//XL represents a significant leap in compute density and power consumption.
Housed in a massive 5U chassis, the //XL architecture features highly powerful multi-core Intel processors, expansive memory footprints, and a dense PCIe Gen 4 topology to support massive NVMe-oF backend scaling. To safely deliver and distribute the necessary wattage to these components while maintaining enterprise-grade high availability, the //XL chassis is equipped with four dedicated Power Supply Units (PSUs).
During physical installation, the Implementation Engineer must connect all four C20 power receptacles to the rack's Power Distribution Units (PDUs). Best practices mandate that these four connections are split across separate PDUs (e.g., PSUs 0 and 2 on PDU A, and PSUs 1 and 3 on PDU B) to ensure N+N power redundancy. Attempting to power the //XL chassis with only two connections will trigger severe hardware fault alerts within Purity and may prevent the array from drawing enough power to safely initialize both controllers and the 40 front-loading DirectFlash Module with Distributed NVRAM (DFMD) slots.
NEW QUESTION # 146
An Implementation Engineer performs a controller upgrade. What is the command to check I/O health?
Answer: A
Explanation:
The command to check I/O health and validate connectivity after a controller upgrade is purehost monitor --balance.
Following an upgrade (especially after a controller reboot or failover/giveback), it is essential to verify that the host Multipath I/O (MPIO) drivers have re-established connectivity to all paths.
purehost monitor: Displays real-time performance statistics (IOPS, Bandwidth, Latency) for connected hosts.
--balance: This specific flag breaks down the metrics per initiator (HBA port) for each host.
Why it's used: An Implementation Engineer uses this to look for "imbalanced" flow. If one initiator shows high IOPS and another shows zero, it indicates a dead path, a zoning issue, or an MPIO driver that failed to recover the path to the upgraded controller. Options A and B provide static configuration lists (mappings and WWNs) but do not show live I/O flow, making them insufficient for health monitoring.

NEW QUESTION # 147
An Implementation Engineer is performing a hardware NDU from a fully populated FlashArray//X90R3 to a FlashArray//XL that already contains 20 DFM-Ds. The drive transfer is complete, and the //XL is still in SPM (Shelf Mode). What is the next step the Implementation Engineer should take to continue the upgrade?
Answer: B
Explanation:
When upgrading from a FlashArray//X to a FlashArray//XL, the hardware migration often involves handling DirectMemory Modules (DMMs) differently than standard data drives. DMMs are high-performance cache modules that reside in the controller chassis.
In this specific scenario-migrating a fully populated //X90R3 to an //XL that already has its own set of DirectFlash Modules (DFM-Ds)-the DMMs from the old chassis need to be moved to the new chassis to preserve their cache function or be properly decommissioned.
The correct procedure is to Evacuate DMMs as a datapack then install into any slot in //XL.
DMMs cannot be simply "hot-swapped" randomly while the system is live in a way that disrupts the cache map.
They must be logically grouped and evacuated (conceptually "vacated" of active data) so they can be safely removed from the old chassis.
Once removed, they can be installed into the new //XL chassis. The //XL architecture supports DMMs in specific slots, and Purity will detect and re-incorporate them into the cache pool.
This ensures that the expensive SCM (Storage Class Memory) hardware is reused in the new system without causing data integrity issues during the transition.

NEW QUESTION # 148
A customer has a FlashArray X20R3 with 22/22 data packs in the chassis at 80% space usage and wishes to swap one of the data packs for a 45TB pack. What step needs to be taken to facilitate this consolidation?
Answer: B
Explanation:
To facilitate a Capacity Consolidation (CapCon) in a chassis that is physically full (both data pack slots occupied) and logically utilized above the threshold to allow internal evacuation, the standard procedure requires temporary external capacity, often referred to as "swing gear." In this scenario, the FlashArray//X20 chassis is fully populated with two 22TB data packs. Since there are no empty slots to insert the new 45TB pack, one of the existing packs must be removed first. However, with the array at 80% usage, the data residing on the pack designated for removal (roughly half the raw capacity) cannot fit into the remaining free space of the other pack.
Therefore, Pure Storage Support will provision a DirectFlash Shelf (DFS) containing temporary capacity (e.g., a 63TB pack as mentioned in Option B). The Implementation Engineer attaches this shelf, adds it to the system, and utilizes it as a destination to evacuate data from the old 22TB pack. Once the old pack is empty and removed, the new 45TB pack is installed into the chassis. Finally, the data is moved from the temporary shelf back into the new chassis capacity, and the temporary shelf is disconnected and returned. Option A is incorrect because an empty shelf provides no storage to offload data, and Option C is operationally unfeasible for most customers.
NEW QUESTION # 149
An Implementation Engineer has completed cabling a DirectFlash Shelf (DFS) to the FlashArray.
Which command should the Implementation Engineer run to verify that the cabling was completed correctly?
Answer: D
Explanation:
Adding an external DirectFlash Shelf (DFS) or a legacy SAS Expansion Shelf to a Pure Storage FlashArray requires precise physical cabling to ensure backend high availability. Because the controllers utilize an active
/active backend topology-where both controllers must maintain redundant loops to every single capacity shelf-a single misplaced cable can cause a severe hardware fault.
Once the physical installation is complete, the Implementation Engineer must definitively validate the topology before handing the array over to production. To do this, they log into the local KVM console or SSH session using the restricted puresetup account. From here, the official Pure Storage post-installation procedure dictates running two specific Python validation scripts: storage_view.py enclosures and storage_view.py config .
While both are used, storage_view.py config is the primary command utilized to map the specific SAS or NVMe-oF (RoCE) port bindings. The script actively polls the physical ports on the rear of the controllers and traces the loops down through the I/O Modules (IOMs) on the shelves. If the cabling is flawless, the CLI will explicitly return: "No errors detected." If a cable is crossed (e.g., Controller 0 plugged into IOM 1 instead of IOM 0), the script will instantly flag the topology mismatch, allowing the engineer to correct it on the spot.
