Ron Stone f125a8b892 Remove spurious escapes (r8,dsR8)
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 Functions: OSDs and SSD-backed Journals

Disks on storage hosts are assigned storage functions in to provide either OSD storage or Ceph journal storage.

Rotational disks on storage hosts are always assigned as object storage devices (OSDs) to provide storage for Application disks. Solid-state disks (SSDs) can be assigned as OSDs, or as journal functions to provide space for Ceph transaction journals associated with OSDs. NVMe-compatible SSDs are also supported.

To assign storage-host disks as OSDs, see Provision Storage on a Controller or Storage Host Using Horizon <provision-storage-on-a-controller-or-storage-host-using-horizon>.

To create SSD-backed journals, see Add SSD-Backed Journals Using Horizon <add-ssd-backed-journals-using-horizon>.
