− | aggregate<ref name="netappspecific">NetApp specific.</ref>
| |
− | It is the highest level of disks grouping. Lower levels are plexes and RAID groups, which are the basis for an aggregate. A volume is created on an aggregate. An aggregate is described by NetApp SMI-S agent using an instance of CIM_StoragePool and is represented as a storage pool in Aperi.

− | filer
| |
− | A shorthand for a NetApp storage system
| |
− |
| |
− | file share
| |
− | A directory or a file that is made available by a filer to clients through NFS or CIFS protocol

| |
− | FlexVol Volume<ref name="netappspecific"/>
| |
− | A FlexVol is a type of [[#volume]] that shares its containing aggregate with many other FlexVols.
| |
− |
| |
− | hot spare disk
| |
− | It is a disk that has not been added yet to any aggregates and can be used to extend an aggregate, to create a new aggregates or to replace a failed disk in an aggregate. ONTAP replaces automatically a failed disk with one of the hot spare disks.

− | LUN
| |
− | Logical unit of storage. Storage Volume and LUNs have equivalent meaning.

| |
− | LUN masking
| |
− |
| |
− | LUN mapping
| |

| |
− | ONTAP<ref name="netappspecific"/>
| |
− | It is the operating system which manages a NetApp storage system.
| |
− |
| |
− | plex<ref name="netappspecific"/>
| |
− | It is an assembly of RAID groups. NetApp defines mirroring at plex level. An aggregate has only one plex when it is unmirrored and two plexes when it is mirrored.

− | Traditional Volume<ref name="netappspecific"/>
| |
− | A traditional volume is a [[volume]] that occupies by itself an entire aggregate.
| |
− |
| |
− | volume<ref name="netappspecific"/>
| |
− | It is file system of type WAFL. The LUNs are created on a volume as files but exposed as block storage space. The file shares are also part of a volume.
