질문 # 192
An Implementation Engineer performing an inventory of hardware for an NDU from an FlashArray//X70R2 to an FlashArray //X90R3 and discovers a complete FlashArray//X90R3 was shipped in place of an NDU kit.
What is the minimum hardware the Implementation Engineer should use from this array to complete the NDU?
정답：B
설명：
To complete the Non-Disruptive Upgrade (NDU) from an //X70R2 to an //X90R3 using a fully shipped array, the Implementation Engineer must extract and use the Controllers and NVRAM modules .
* Stateless Architecture: The FlashArray upgrade philosophy allows the chassis and data drives (Data Packs) to remain in place while the compute (controllers) and cache (NVRAM) are swapped.
* Component Compatibility:
* Controllers: The X90R3 controllers provide the upgraded CPU/performance required.
* NVRAM: The NVRAM modules (located in the chassis front or rear slots depending on generation, but logically paired with controller performance) often differ between generations (R2 vs. R3) and performance tiers (70 vs. 90). The X70R2 NVRAM modules are typically not compatible with X90R3 controllers. Therefore, the engineer must swap the NVRAM modules along with the controllers to ensure the write cache is recognized.
* Power Supplies: Both the X70R2 and X90R3 utilize the same high-capacity 1600W Power Supply Units . Unless the existing PSUs are faulty, they do not technically need to be swapped for the system to function, making "Controller and NVRAM" the precise minimum requirement for the logic upgrade.
질문 # 193
What is the speed of the Ethernet ports to connect a FlashArray //E to a DFS?
정답：C
설명：
FlashArray//E models utilize 25Gb Ethernet (25G) ports for connecting to DirectFlash Shelves (DFS). These 25G ports are designed to handle the high throughput demands of DFS, providing efficient data transfer between the storage array and expansion shelves. This configuration ensures optimal performance and scalability for FlashArray//E systems.
질문 # 194
Which cards are required to connect a DirectFlash Shelf to an FlashArray//XLR5?
정답：B
설명：
The FlashArray//XL series (specifically the //XLR5 in this context) utilizes a 100 Gigabit Ethernet-based back-end fabric to communicate with DirectFlash Shelves (DFS). This connection relies on the RoCE (RDMA over Converged Ethernet) protocol to ensure low-latency access to the external NVMe modules.
The specific PCIe interface card validated for this connectivity is often labeled in the Bill of Materials (BOM) or configuration guides as the 2-Port 100GbE iSCSI/RoCE card (or simply the 100GbE Ethernet/RoCE card depending on the specific firmware/labeling revision). Crucially, it must be a 100GbE capability card.
The //XL platform standardized on 100GbE for its shelf interconnects, moving away from the 50GbE used in some previous generations of the //X series. The 200GbE cards are typically reserved for high-speed host connectivity or clustering, not the standard shelf loop. Therefore, ensuring the BOM includes the correct 100GbE RoCE-capable cards is essential for successful shelf detection and operation during installation.
질문 # 195
A dark site customer requests an evacuation of SH01 on a FlashArray/M50. What is an appropriate next step?
정답：C
설명：
For a Dark Site customer (where Remote Assist and PhoneHome are disabled), the appropriate next step before performing a shelf evacuation is to use the evac_checks script.
Risk Mitigation: Evacuating a shelf is a resource-intensive operation that permanently removes physical capacity from the system. In a connected environment, Pure Support runs remote diagnostics to verify the array has enough free space and system resources to handle the evacuation safely.
Dark Site Procedure: Since Support cannot log in remotely, the Implementation Engineer must manually run the evac_checks python script (typically loaded via USB or available in the Purity toolkit). This script performs the equivalent validation: checking effectively used capacity, dedup ratios, and system load to predict if the remaining drives can absorb the data from Shelf 01 without filling the array to 100% or causing performance degradation. Relying solely on a generic percentage (Option B or C) is dangerous because it doesn't account for data reduction overhead or specific RAID overheads.
질문 # 196
When adding a data pack into a FlashArray chassis or a DFS shelf, the drives show "unrecognized" status when running List. What is the cause of this status on the newly inserted drives?
정답：C
설명：
The status "unrecognized" on a drive module typically indicates that the physical hardware is detected by the chassis midplane, but the operating system (Purity) does not have the necessary driver definition or firmware logic to interact with it.
This most commonly occurs when newer generation DirectFlash Modules (e.g., larger capacity drives or newer NAND revisions) are inserted into an array running an older version of Purity. The hardware identifier of the new drive is unknown to the older software .
To resolve this, the Implementation Engineer must verify the Purity Compatibility Matrix for the specific drive part number. The array will likely need a Purity software upgrade to a version that supports the new media before the drives can be successfully admitted and used. It is rarely a hardware fault (which would show as "failed" or "missing") or a capacity limit (which would prevent admission but usually identify the drive correctly).
