Other SSD mirror settings

OneFS creates multiple mirrors for file system structures and, by default, stores one mirror for each of these structures on SSD. You can specify that all mirrors for these file system structures be stored on SSD.

OneFS creates mirrors for the following file system structures:

For each structure, OneFS creates multiple mirrors across the file system and stores at least one mirror on an SSD. Because SSDs provide faster I/O than HDDs, OneFS can more quickly locate and access a mirror for each structure when needed.

Alternatively, you can specify that all mirrors created for those file system structures are stored on SSDs.

The capability to change the default mirror setting for system B-tree, system delta, and QAB is available only in the OneFS CLI, specifically in the isi storagepool settings command.
