Set the Metadata Tier
Metadata tiering provides the ability to store data and metadata in different storage tiers or LUNs. Metadata tiering allows
storing of metadata items on faster disks, benefiting workloads which are metadata-oriented but require low-cost disks for most
of their data. This feature is disabled by default, and can be enabled at any time during system operation. Metadata tiering is
disabled when the system is updated from an older version of the firmware.
About this task
When creating or expanding a NAS pool, administrators can select the percentage of the FluidFS NAS pool capacity to be
allocated for the metadata tier. For example, High Priority (Tier 1) stores approximately 12.5 percent of the storage for FluidFS
in the metadata tier whereas Low Priority (Tier 3) stores approximately 3 percent of the storage for FluidFS in the metadata
tier.
