Exports
Managing the NAS Pool
The amount of raw space allocated to the FluidFS cluster (NAS pool) is determined by the MD Array LUNs
assigned to the NAS controllers. The maximum size of the PowerVault FluidFS NAS pool is 1 PB.
The usable size of the NAS pool depends on how much space the system deducts from the NAS pool for
internal use. On average, the system deducts approximately 400 GB per NAS appliance for internal use.
The exact amount of internal space varies by configuration, but it is roughly calculated as follows per
FluidFS cluster:
(256GB ∗ number of NAS appliances) + (4GB ∗ number of MD LUNs/volumes) + 20GB + 0.5% of the
total NAS pool + (100GB * number of NAS appliances, if data reduction is enabled)
