Set the Metadata Tier
Metadata tiering provides the ability to store data and metadata in dierent storage tiers or LUNs. Metadata tiering allows storing of
metadata items on faster disks, beneting 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 rmware.
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.
