FS8600 Scale-Out NAS Terminology
The following table denes terminology related to FS8600 scale-out NAS.
Term Description
Fluid File System (FluidFS) High-performance, scalable le system software installed on NAS controllers.
Appliance (NAS appliance) A rack-mounted 2U chassis that contains two hot-swappable NAS controllers in an active-active
conguration in a FluidFS cluster. Cache data is mirrored between the paired NAS controllers within
the NAS appliance.
Controller (NAS controller) The two primary components of a NAS appliance, each of which functions as a separate member in
the FluidFS cluster.
Peer controller The NAS controller with which a specic NAS controller is paired in a NAS appliance.
Standby controller A NAS controller that is installed with the FluidFS software but is not part of a FluidFS cluster. For
example, a new or replacement NAS controller from the Dell factory is considered a standby
controller.
Backup power supplies Each NAS controller contains a backup power supply that provides backup battery power in the
event of a power failure.
FluidFS cluster One to six FS8600 scale-out NAS appliances congured as a FluidFS cluster.
Storage Center Up to eight Storage Centers that provide the NAS storage capacity.
Storage Manager Multisystem management software and user interface required for managing the FluidFS cluster and
Storage Centers(s).
FS8600 Scale-out NAS A fully congured, highly available, and scalable FluidFS cluster, providing NAS (SMB and NFS)
services. The cluster comprises NAS appliances, storage provided by one or more Storage Centers
and Storage Manager.
FTP File Transport Protocol, used to transfer les to and from the FluidFS cluster.
NAS pool The sum of all storage provided by up to eight Storage Centers minus space reserved for internal
system use.
NAS volume A virtualized volumes that consumes storage space in the NAS pool. Administrators can create SMB
shares and NFS exports on a NAS volume and share them with authorized users.
LAN or client network The network through which clients access SMB shares or NFS exports. This network is also used by
the storage administrator to manage the FluidFS cluster.
Client VIP One or more virtual IP addresses that clients use to access SMB shares and NFS exports hosted by
the FluidFS cluster.
SMB Share A directory in a NAS volume that is shared on the network using the Server Message Block (SMB)
protocol.
NFS export A directory in a NAS volume that is shared on the network using the Network File System (NFS)
protocol.
Network Data Management
Protocol (NDMP)
Protocol used for NDMP backup and restore operations.
Replication Copies NAS volume data between two FluidFS clusters or between two NAS volumes.
Replication partners FluidFS clusters participating in a replication operation.
