FS8600 Scale-Out NAS Terminology

The following table defines terminology related to FS8600 scale-out NAS.


Term	Description
Fluid File System (FluidFS)	High-performance, scalable file 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 configuration 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 specific 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 configured as a FluidFS cluster.
Storage Center	Up to eight Storage Centers that provide the NAS storage capacity.
Dell Storage Manager	Multisystem management software and user interface required for managing the FluidFS cluster and Storage Centers(s).
FS8600 Scale-out NAS	A fully configured, 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 Dell Storage Manager.
FTP	File Transport Protocol, used to transfer files 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.
Snapshot	An image of all the NAS volume data frozen as read-only at a specific point in time.
