    Cloud Storage Gateway:What are the differences between a cross-zone HA file gateway and a standalone file gateway?

    Last Updated:Mar 25, 2025

    This topic describes the differences between a cross-zone high-availability (HA) and a standalone file gateway.

    A cross-zone HA file gateway and a standalone file gateway have the following differences.

    Cross-zone HA file gateway

    Standalone file gateway

    Usage

    Virtual IP addresses are required to use a cross-zone HA file gateway. You can change virtual IP addresses.

    The IP address is automatically assigned and cannot be changed.

    • A cross-zone HA file gateway is deployed on different nodes.

    • When you create shares, you can bind them to different virtual IP addresses.

    • The shares are created on the gateway instance.

    • The shares are associated with the assigned IP address.

    Architecture

    Two nodes are deployed in two zones to ensure service availability in case of single points of failures.

    Only a single node is available. A standalone file gateway becomes unavailable if the zone fails.

    Read/Write bandwidth limits

    A cross-zone HA file gateway is deployed on two nodes. The maximum read bandwidth of a cross-zone HA file gateway is twice that of a standalone file gateway. The maximum write bandwidth of a cross-zone HA file gateway is the same as that of a standalone file gateway.

    Read/Write latency

    A cross-zone HA file gateway utilizes data replication internally, resulting in higher write latency compared with a standalone file gateway. The write latency of a cross-zone HA file gateway is influenced by the network latency between zones. However, the HA architecture does not affect read latency.
