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 configuring 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 configuration, 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)

Steps
1. In the Storage view, select a FluidFS cluster.
2. Click the Summary tab.
The NAS Pool Status panel displays the configured size of the NAS pool.
Expand the Size of the NAS Pool
You can increase the size of the NAS pool as your NAS storage space requirements increase, without affecting the services to
the clients. However, you cannot decrease the size of the NAS pool.
Prerequisites
The Storage Centers must have enough capacity to allocate more storage space to the FluidFS cluster.
The maximum size of the NAS pool is:
2 PB with one Storage Center
4 PB with two Storage Centers
Steps
1. In the Storage view, select a FluidFS cluster.
2. Click the Summary tab.
