NEW QUESTION # 232
What is the speed of the Ethernet ports to connect a FlashArray //E to a DFS?
Answer: A
Explanation:
The FlashArray//E connects to its DirectFlash Shelves (DFS) using 25Gb Ethernet (RoCE) .
The FlashArray//E is the "Capacity Optimized" member of the FlashArray family, designed to replace spinning disk repositories with all-flash efficiency. While the high-performance FlashArray//XL utilizes
100GbE for its backend NVMe-oF connectivity to maximize throughput for mission-critical databases, the //E prioritizes cost-efficiency, density, and power consumption.
* Architecture: To maintain this efficiency balance, the backend connectivity for expansion shelves on the //E platform is standardized on 25GbE . This provides ample bandwidth for the QLC-based workloads (typically unstructured data, repository, or Tier 2 block) without the higher cost and power draw of 100GbE optics and controllers.
* Comparison: Option A (40G) is a legacy QSFP standard not used in modern Pure backend designs.
Option C (100G) is reserved for the performance-tier //XL and high-end //X models.
NEW QUESTION # 233
An Implementation Engineer is installing a second DirectFlash Shelf (DFS) on a FlashArray//XR4 controller. How should the Implementation Engineer complete the installation?
Answer: C
Explanation:
The FlashArray//XR4 introduces a new chassis layout and PCIe slot numbering scheme compared to previous generations. For expansion connectivity, specific slots are designated for the backend SAS or Ethernet/RoCE fabric cards that connect to DirectFlash Shelves.
According to the //XR4 hardware guide and expansion best practices, PCIe slot 3 is the designated location for the additional expansion interface card required when adding a second DirectFlash Shelf (or for specific shelf configurations). Slots 0 and 1 are often reserved for host I/O or other functions, and slot numbering/priority is strict to ensure the BIOS and Purity software correctly recognize the card function.
Installing the card in the wrong slot (like slot 0 or 4, if those are reserved for other uses or primary I/O) could result in the shelf not being detected, the array failing to boot, or suboptimal performance due to PCIe lane allocation. Therefore, the engineer must install the DFS expansion card into PCIe slot 3 and cable the second shelf to the ports on that specific card to ensure a supported and functional configuration.
NEW QUESTION # 234
What is the maximum number of DirectFlash Shelves supported for FlashArray//XL?
Answer: C
Explanation:
The FlashArray//XL currently supports a maximum of 2 DirectFlash Shelves (DFS) .
The FlashArray//XL is a high-density, performance-optimized platform housed in a 5U chassis.
* Rack Unit Math: According to the FlashArray//XL specifications and site planning guide, the system supports a maximum configuration footprint of 11 Rack Units (11U) .
* The base controller chassis occupies 5U .
* Each DirectFlash Shelf occupies 3U .
* Therefore: 5U (Base) + 3U (Shelf 1) + 3U (Shelf 2) = 11U .
* Capacity: Because the //XL chassis itself holds 40 DirectFlash Modules (compared to 20 in a standard
//X), and each shelf holds 28 modules, a fully populated system with two shelves provides nearly 100 drives of capacity (40 + 28 + 28 = 96 drives). This massive density reduces the need for "daisy- chaining" large numbers of shelves like legacy SAS architectures. Adding a third shelf would push the total height to 14U, exceeding the current platform definition.
NEW QUESTION # 235
Where can the NVRAM on a FlashArray//E be located?
Answer: B
Explanation:
Understanding the hardware architecture of the Pure Storage FlashArray//E is crucial for proper deployment and capacity management. The FlashArray//E (and FlashBlade//E) family was specifically engineered to deliver an all-flash solution for capacity-optimized, tier-2 workloads and unstructured data repositories, aiming to replace legacy spinning disk (HDD) environments entirely.
To achieve this massive storage density at a disruptive price point, the //E series exclusively utilizes Quad- Level Cell (QLC) flash. While older arrays (like the //X50) use strictly dedicated NVRAM modules centrally located in the chassis, and higher-end TLC arrays (like the //XL) use DirectFlash Modules with Distributed NVRAM (DFMDs), the FlashArray//E utilizes a highly specialized drive.
On the FlashArray//E, the non-volatile write cache is distributed across DFMes . "DFMe" is the specific Pure Storage hardware nomenclature for a QLC-based DirectFlash Module that includes integrated, distributed NVRAM. By moving the NVRAM directly onto the QLC capacity modules, the //E architecture eliminates the need for dedicated NVRAM bays, streamlines the write path, and allows the write cache bandwidth to scale linearly as the customer adds more capacity to the system.
NEW QUESTION # 236
A customer wants to expand the capacity of their FlashArray//X10 from 5/5 to 11/11. Which is the correct action to take?
Answer: B
Explanation:
To expand a FlashArray//X10 from a 5/5 (fully populated chassis with two 5TB equivalent packs) to an 11/11 (two 11TB equivalent packs) configuration, the correct action is to install a swing shelf with loan capacity.
The Constraint: The "5/5" notation implies the chassis slots are already occupied by the existing media. Since the customer is replacing the existing packs with larger ones (Capacity Consolidation) rather than just adding new ones, the engineer needs a place to put the data during the swap.
Why Swing Shelf: The FlashArray//X10 chassis has limited slots. You cannot simply pull a pack (Option A) if the remaining pack doesn't have enough free space to hold all the data (which is typical in upgrade scenarios). A Swing Shelf (temporary external SAS or NVMe shelf provided by Pure) is attached to the array. The data is evacuated from the internal drives to this shelf. Once the internal slots are empty, the new 11TB packs are installed. The data is then moved back from the shelf to the new packs, and the shelf is removed.
