The NetApp FAS8000 and FAS9000 systems with the FlexArray feature of ONTAP support attachment of external storage. The external storage is virtualized by ONTAP enabling the advanced features and a common management for volumes allocated to a NetApp aggregate. The release of the FlexArray feature on the high-end systems replaced the V-series systems for virtualizing external storage.
The NetApp Fabric Attached Storage (FAS) series of FAS2600, FAS8200, and FAS9000 models support Fibre Channel SAN, FCoE, IP SAN (iSCSI), and network-attached storage (NAS) environments via NFS and CIFS. All SSD versions using the same ONTAP software are offered as All Flash FAS (AFF) systems and are covered in a separate Evaluator Group document.
NetApp refers to fabric-attached storage systems as storage connected to hosts via any network. The FAS series is part of NetApp’s strategy to offer a network storage system that is capable of supporting both NAS and storage-area network (SAN) accessibility from a single storage pool.
The embedded operating software is called ONTAP and support scale-out clustering and advanced feature capabilities. ONTAP 9 replaces the earlier clustered Data ONTAP (cDOT) and 7-mode (non-clustered). A cloud version of ONTAP is also available and is called Cloud ONTAP.
NetApp ONTAP has scale out capability to allow systems to be configured to match the environment needs and to increase in both capacity and performance as required. The scale out capability with ONTAP allows scaling to 24 controllers (12 HA pairs) along with the capacity scaling for NAS and 16 (eight HA pairs) for block mode. A dual node NetApp system is called a High Availability pair configuration.
Data reduction in the form of deduplication, compression, and compaction are supported on NetApp systems for primary data. The data reduction is performed inline and NetApp provides a 4:1 reduction guarantee. Compaction is filling the 4K allocation chunks with smaller blocks, which can improve storage utilization, especially with small files.
