Fibre Channel (FC) I/O cards are compatible across all FlashArray models, providing consistent SAN connectivity regardless of array generation.

Mirrored Write statistics appear in the Purity GUI’s Analysis section when ActiveCluster is enabled, as it tracks synchronous replication activity between clusters.

On FlashArray//XR2/3 FC arrays, the default PCIe Fibre Channel card is a 2-port card installed in slot 2, providing standard FC connectivity.

iSCSI cards can be reused when upgrading from XR2 to XR3 controllers, supporting hardware continuity within this upgrade path.

The upgrade kit for an //X to //XL Non-Disruptive Upgrade (NDU) includes 2 QSFP cables, 3 Mellanox InfiniBand cards, and 20 DirectFlash Modules (DFMDs) to support new hardware connectivity and capacity requirements.

Drive relocation should be performed only after the XFORM upgrade completes to avoid disrupting the upgrade process and ensure data integrity.

FlashArray//XL power supply units (PSUs) are designed with 2+2 redundancy, meaning there are four PSUs where any two can fail without impacting array operation.

The provided netmask "255.255.255.223" is invalid. Changing it to the standard subnet mask "255.255.255.0" aligns correctly with the gateway "10.24.18.1" for proper network configuration.

Upgrading from FlashArray X10 to X50 requires upgrading power supplies to meet the higher power demands of the larger chassis and expanded hardware.

The FlashArray//XR2 and //XR3 models each occupy 3 rack units (RU) in height. This is specified in the FlashArray//XR2 and //XR3 Site Planning Guide, which outlines the physical requirements for rack space, clearance, and weight for these models.

Cage nuts should be placed in the lowest square hole of the lowest rack unit (RU) where the array rails will be installed to ensure proper alignment and support.

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 FlashArray//XL supports up to four DirectFlash Shelves (DFS), each providing up to 1.9PB of effective capacity, enabling a total effective capacity of up to 7.6PB when fully expanded.

Adding the host itself to a protection group automatically includes all volumes connected to that host, ensuring comprehensive data protection without manual volume-by-volume assignment.

The command hwconfig --model returns the model information of the controller, which is essential before running the puresetup replace procedure.

Opening a support case before starting the installation ensures timely assistance and coordination with support throughout the deployment process.

To properly configure the proxy server, both the protocol prefix (e.g., http:// or https://) and the port number are required along with the IP address.

The command purealert untag --maintenance removes the maintenance tag after a hardware upgrade, signaling the system that maintenance mode has ended.

FlashArray//XCR4 arrays are shipped with 32Gb Fibre Channel (FC) SFPs by default. These 32Gb FC SFPs are capable of supporting 64Gb speeds, which can be enabled via a firmware upgrade. This allows the array to leverage higher-speed FC connections as needed.
