haPairs

Specifies how many high-availability (HA) pairs of file servers will power your file system. First-generation file systems are powered by 1 HA pair. Second-generation multi-AZ file systems are powered by 1 HA pair. Second generation single-AZ file systems are powered by up to 12 HA pairs. The default value is 1. The value of this property affects the values of StorageCapacity, Iops, and ThroughputCapacity. For more information, see High-availability (HA) pairs in the FSx for ONTAP user guide. Block storage protocol support (iSCSI and NVMe over TCP) is disabled on file systems with more than 6 HA pairs. For more information, see Using block storage protocols.

Amazon FSx responds with an HTTP status code 400 (Bad Request) for the following conditions:

• The value of HAPairs is less than 1 or greater than 12.

• The value of HAPairs is greater than 1 and the value of DeploymentType is SINGLE_AZ_1, MULTI_AZ_1, or MULTI_AZ_2.
