Feature Description
High-performance, scale-out NAS Support for a single namespace spanning up to four NAS appliances (eight NAS
controllers).
Capacity scaling Ability to scale a single namespace up to 4-PB capacity with two Storage Centers.
Connectivity options Oers 1GbE and 10GbE copper and optical options for connectivity to the client
network.
Highly available and active-active design Redundant, hot-swappable NAS controllers in each NAS appliance. Both NAS controllers
in a NAS appliance process I/O.
Automatic load balancing Automatic balancing of client connections across network ports and NAS controllers, as
well as back-end I/O across Storage Center volumes.
Multiprotocol support Support for SMB (on Windows), NFS (on UNIX and Linux), and FTP protocols with
ability to share user data across both protocols.
Client authentication Controls access to les using local and remote client authentication, including LDAP,
Active Directory, and NIS.
Quota rules Control client space usage.
File security style Choice of le security mode for a NAS volume (UNIX, Windows, or Mixed).
Storage Center Data progression Automatic migration of inactive data to less-expensive drives.
Storage Center Dynamic capacity Thin-provisions the block-level storage allocated to the NAS pool and NAS volumes and
consumes space only when writes occur.
Cache mirroring The write cache is mirrored between NAS controllers, which ensures a high-
performance response to client requests and maintains data integrity in the event of a
NAS controller failure.
Journaling mode In the event of a NAS controller failure, the cache in the remaining NAS controller is
written to storage and the NAS controller continues to write directly to storage, which
protects against data loss.
Backup power supply Maintains data integrity in the event of a power failure by keeping a NAS controller
online long enough to write the cache to the internal storage device.
NAS volume thin clones Clones NAS volumes without needing to physically copy the data set.
Deduplication Policy-driven post-process deduplication technology that eliminates redundant data at
rest.
Compression A variant of LZ77 compression algorithm that intelligently shrinks data at rest.
Metadata protection Metadata is constantly checksummed and stored in multiple locations on both the FS
Series appliance and within the Storage Centers for data consistency and protection.
Snapshots Redirect-on-write snapshots that are user-accessible over the network.
Replication NAS volume-level, snapshot-based, asynchronous replication to remote FluidFS clusters
to enable disaster recovery.
NDMP backup Snapshot-based, asynchronous, two-way backup (direct NDMP), or three-way backup
(remote NDMP) over Ethernet to certied third-party backup solutions.
Antivirus scanning SMB antivirus scanning ooading using certied third-party, Internet Content
Adaptation Protocol (ICAP)-enabled antivirus solutions.
Monitoring Built-in performance monitoring and capacity planning.
