This change addresses a long-standing issue in rST documentation imported from XML.
That import process added backslash escapes in front of various characters. The three
most common being '(', ')', and '_'.
These instances are removed.

Storage on Storage Hosts
Storage hosts provide a large-scale, persistent and highly available Ceph cluster for backing .
The storage hosts can only be provisioned in a Standard with dedicated storage deployment and comprise the storage cluster for the system. Within the storage cluster, the storage hosts are deployed in replication groups for redundancy. On dedicated storage setups Ceph storage backend is enabled automatically, and the replication factor is updated later, depending on the number of storage hosts provisioned.
OSD Replication Factor
| Replication Factor | Hosts per Replication Group | Maximum Replication Groups Supported |
|---|---|---|
| 2 | 2 | 4 |
| 3 | 3 | 3 |
You can add up to 16 per storage host for data storage.
Space on the storage hosts must be configured at installation before you can unlock the hosts. You can change the configuration after installation by adding resources to existing storage hosts or adding more storage hosts. For more information, see the StarlingX Installation and Deployment Guide.
Storage hosts can achieve faster data access using -backed transaction journals (journal functions). -compatible are supported.
