What are the differences and performance comparison between cross-zone HA file gateways and Basic Edition file gateways?

Cross-zone HA file gateway

File Gateway (Basic Edition)

Usage

You must configure a virtual mount IP address to use the gateway. The virtual mount IP address can be modified.

The system automatically assigns the mount IP address. The IP address cannot be modified.

• Shares are deployed on different nodes.

• You can attach different virtual mount IP addresses when you create a share.

• Shares are created on the instance node.

• The assigned mount IP address is attached.

Architecture

Includes two service nodes deployed in different zones. This ensures availability if a single point of failure occurs.

Includes a single service node. Availability issues may occur if the zone fails.

Instance read/write bandwidth limit

Cross-zone HA file gateways support deploying shares on two nodes. The total read bandwidth limit of the instance is twice that of a Basic Edition file gateway. The write bandwidth limit is the same as that of a Basic Edition file gateway.

Instance read/write latency

Cross-zone HA file gateways use synchronous data replication. As a result, the latency of write requests is affected by the network latency between zones and is slightly higher than that of Basic Edition file gateways. Read requests are not affected.
