About NAS Architecture
NAS architecture is an advanced clustered architecture, providing the performance of a networked le system with the eciency of
a storage system.
Figure 6. NAS Hardware Architecture shows a typical conguration, although other types of congurations are possible. Table 8. NAS
Hardware Architecture explains the callouts used in the gure.

Callout Description
1 PS Series group (partial)
Storage area network (SAN) comprising one or more PS Series arrays connected to an IP network. Arrays are
high-performance (physical) block-storage devices.
2 NAS cluster
Collection of NAS hardware (appliances) congured as part of a PS Series group.
3 NAS appliances
Hardware enclosures that contain NAS controllers.
4 NAS controllers
Redundant, hot-swappable controllers in NAS appliances. The controllers interface over a fabric to the PS
Series SAN storage.
Figure 7. NAS Software Architecture shows a logical representation of the NAS cluster. Table 9. NAS Software Architecture explains
the callouts used in the gure.
