# Enhanced Read Scalability with Read Replicas

<EnterpriseAlert>

This feature requires{' '}

<a href="https://www.hashicorp.com/products/consul/">Consul Enterprise</a>{' '}

with the Global Visibility, Routing, and Scale module.

|
|
Consul Enterprise provides the ability to scale clustered Consul servers
|
|
to include voting servers and read replicas. Read replicas still receive data from the cluster replication,
|
|
however, they do not take part in quorum election operations. Expanding your Consul cluster in this way can scale
|
|
reads without impacting write latency.
|

|
|
For more details, review the [Consul server configuration](/docs/agent/config)
|
|
documentation and the [-read-replica](/docs/agent/config/cli-flags#_read_replica)
|
|
configuration flag.
