FluidFS NAS Volumes, Shares, and Exports
This section contains information about managing the FluidFS cluster from the client perspective. These tasks are performed using the
Storage Manager Client.
Managing the NAS Pool
When conguring a FluidFS cluster, you specify the amount of raw Storage Center space to allocate to the FluidFS cluster (NAS pool). The
maximum size of the NAS pool is:
• 2 PB with one Storage Center.
• 4 PB with eight Storage Centers
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 conguration, but
it is roughly calculated as follows per FluidFS cluster:
(256 GB ∗ number of NAS appliances) + (4 GB ∗ number of Storage Center volumes) + 20 GB + 0.5% of the total NAS pool + (100 GB *
number of NAS appliances, if data reduction is enabled)
