FlashArray-Implementation-Specialist Exam Dumps - Pure Certified FlashArray Implementation Specialist (FAIS) Exam

Modern Pure Storage FlashArrays support unified block and file storage directly out of the box (often referred to as FA File). To utilize file protocols like SMB or NFS on the array, the Implementation Engineer must properly configure the networking interfaces to handle file-specific traffic.

Purity handles network traffic routing by assigning specific "services" to its Ethernet interfaces or Virtual Interfaces (VIFs). When creating or modifying a virtual network interface using the purenetwork CLI suite (or via the GUI), the engineer must explicitly define what type of traffic is allowed to traverse that interface.

To configure a subnet and virtual interface dedicated to File Services, the --service flag must be set to file. For example, a common command structure would look like:

purenetwork setattr --service file < interface_name >

Assigning the iSCSI service would strictly format the port to listen for block-level SCSI commands over TCP/IP, Replication would reserve the port for array-to-array snapshot transfers or ActiveCluster traffic, and Management would restrict the port to GUI/CLI administrative access. Only the file service type enables the necessary protocol daemons to export NFS shares and SMB directories out of that specific network port.

At the completion of an upgrade, the correct command to manually trigger the upload of the relevant logs is purearray phonehome --send-today .

Purpose: This specific argument (--send-today) instructs the array to bundle and upload all log files generated within the current 24-hour window. This is the standard procedure post-upgrade because it ensures that all logs capturing the pre-upgrade state, the upgrade process itself, and the immediate post-upgrade health checks are transmitted to Pure Support.

Verification: This allows the Support team to validate that the upgrade completed successfully and that no dormant issues were triggered during the controller failovers.

Syntax: Option A (purelogs) is not a valid command. Option B (--send-logs) is a generic approximation, but the specific "today" flag is the best practice command cited in upgrade checklists to avoid uploading gigabytes of historical data irrelevant to the immediate event.

The FlashArray//XL series (such as the XL130R5) utilizes a modern backend connectivity architecture for its expansion shelves, specifically the DirectFlash Shelf (DFS). Unlike older generations that might have used SAS (Serial Attached SCSI) for shelf connectivity, the //XL architecture relies on high-speed Ethernet with RoCE (RDMA over Converged Ethernet) to communicate with external media shelves. This ensures that the NVMe drives in the shelf perform with the same low latency as those in the head unit.

To attach a DirectFlash Shelf to a FlashArray//XL130R5, the chassis must be populated with specific PCIe interface cards designated for shelf back-end connectivity. The correct part for this is the FA-XL-100G Ethernet/RoCE 2-Port card. This card provides the necessary 100 Gigabit Ethernet bandwidth and RoCE protocol support required for the NVMe-oF (NVMe over Fabrics) backend fabric that Pure Storage uses.

It is crucial to distinguish this from host-facing cards. While an "iSCSI/RoCE" card exists, the shelf connectivity specifically utilizes the "Ethernet/RoCE" designation in the BOM to differentiate backend fabric ports from frontend host ports. The 200G options are generally reserved for host connectivity or inter-array clustering in specific high-performance setups, but the standard validated card for connecting the DFS to the //XL130R5 is the 100G Ethernet/RoCE adapter. Verifying this line item on the BOM prevents onsite delays where the engineer might otherwise find themselves with incompatible ports for the expansion shelves.

Consistent with previous FlashArray generations, the FlashArray//XR4 adheres to the standard port designation for administrative connectivity.

ETH0 is the primary port enabled for the management service by default.

When an Implementation Engineer first connects to a new //XR4 controller to perform the initial IP configuration, they utilize ETH0 (and often ETH1 for redundancy).

These ports are physically labeled for management and are logically separated from the data and replication traffic in the default configuration.

ETH2 and ETH3 are typically reserved or defaulted for replication traffic, while higher-numbered ports (like ETH10+) are used for host I/O or backend shelf connectivity on the R4 platform. Using ETH0 ensures immediate access to the Purity GUI and CLI without requiring custom port reconfiguration.

The FlashArray//XR4 architecture fundamentally changed how external capacity is attached compared to older SAS-based or early NVMe platforms. Because DirectFlash Shelves (DFS) utilize massive 100GbE RDMA over Converged Ethernet (RoCE) for their backend loops to maintain NVMe-level performance, specific port and slot assignments are heavily regulated.

On an //XR4 model (such as the //X70 R4 or //X90 R4), the controllers feature dedicated, integrated 100GbE ports on the motherboard (specifically eth18 and eth19) which are strictly reserved for the first DirectFlash Shelf loop.

However, when an Implementation Engineer needs to install a second DirectFlash Shelf, the integrated onboard ports are already fully saturated. Pure Storage does not support daisy-chaining NVMe-oF RoCE shelves in the same manner as legacy SAS enclosures. Instead, a new dedicated backend fabric loop must be established. To accomplish this, the engineer must install an additional 100GbE RoCE PCIe expansion card. According to the official //XR4 PCIe Slot Population Matrix, the designated location for this secondary backend expansion card is PCIe Slot 4 . Installing the card into other frontend-designated slots (like Slot 0 or Slot 3) will trigger a topology mismatch during the array's pre-flight hardware checks and prevent the new shelf from initializing.

The Customer is the mandatory party required to provide completion sign-off before the Implementation Engineer leaves the site.

According to the FlashArray Implementation Service Brief and standard operating procedures, the final step of the deployment phase is the "Project Sign-off." After the engineer has racked, cabled, initialized, and verified the array's health (often demonstrating connectivity and the Purity GUI), the customer must formally acknowledge that the installation meets the agreed-upon scope of work. This sign-off serves as the legal and operational acceptance of the hardware and software implementation.

While the Account Team manages the commercial relationship and Support may assist with technical hurdles, neither can validate that the physical implementation meets the customer's specific on-site requirements or that the "handover" of administration has occurred. The customer's signature (physical or digital) on the implementation checklist or service completion form signals the transition from the "Deployment" phase to the "Production/Support" phase.

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).

The Pure1 mobile app provides convenient access to array monitoring and management features from anywhere. Most features, such as viewing performance telemetry (Option A) or managing support tickets (Option B), are cloud-native and accessible over the public internet via the secure Pure1 connection.

However, Opening Remote Assist (RA) —the feature that creates a secure tunnel for Pure Storage Support to access the array remotely—is a privileged security action. To prevent unauthorized external actors from enabling this access, the Pure1 app often enforces a "proximity" or network validation check. The user must be connected to the internal company network (e.g., via Wi-Fi or VPN) that has visibility to the array's management interface to authorize the Remote Assist session. This requirement ensures that only an authorized administrator physically or logically present within the customer's secure environment can grant external access to the storage system.
