When accessing the FlashArray GUI, which management IP address is recommended for use?

FlashArray controllers operate in an Active/Active high-availability cluster. Each controller (CT0 and CT1) has its own physical IP address for hardware-level management. However, Purity configures aVirtual IP (VIP)that floats between the two controllers.

TheVirtual management IPis the recommended address for all administrative access, including the GUI, CLI, and API integrations. Using the VIP ensuresHigh Availability (HA)for management sessions. If an Implementation Engineer were to log in directly to CT0's IP and CT0 subsequently rebooted (e.g., during an NDU or failure), the management session would be disconnected.

By contrast, the VIP automatically fails over to the surviving controller (CT1) in the event of a disruption, allowing the management session (and the GUI) to remain accessible. This abstraction layer simplifies administration, as the user does not need to know which controller is currently "primary" for management tasks. Direct controller IPs are typically reserved for specific hardware troubleshooting steps where accessing a specific node is required.
