Dell PowerVault NX3500 - Manual (Page 13)

Feature Description
Connectivity options 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. BPS allows
maintaining 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.
Automatic load balancing Automatic balancing of client connections across network ports
and NAS controllers, as well as back ‐end I/O across MD array
LUNs.
Multi ‐protocol support Support for CIFS/SMB (on Windows) and NFS (on UNIX and Linux)
protocols with ability to share user data across both protocols.
Client authentication Control access to files using local and remote client
authentication, including LDAP, Active Directory, and NIS.
Quota rules Support for controlling client space usage.
File security style Choice of file security mode for a NAS volume (UNIX or NTFS).
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.
NAS volume thin clones Clone NAS volumes without the need to physically copy the data
set.
Deduplication Policy ‐driven post‐process deduplication technology that
eliminates redundant data at rest.
Compression LZPS (Level Zero Processing System) compression algorithm that
intelligently shrinks data at rest.
Metadata protection Metadata is constantly check-summed and stored in multiple
locations for data consistency and protection.
Replication NAS-volume level, snapshot ‐based, asynchronous replication to
enable disaster recovery.
Snapshots Redirect ‐on‐write, user‐accessible snapshots
NDMP backups Snapshot ‐based, asynchronous backup (remote NDMP) over
Ethernet to certified third ‐party backup solutions.
Anti ‐virus scanning CIFS anti ‐virus scanning by deploying certified third‐party ICAP‐
enabled anti ‐virus solutions.
Monitoring Built ‐in performance monitoring and capacity planning.
Overview Of PowerVault FluidFS Systems
PowerVault FluidFS system consists of one or two PowerVault NX36x0 appliances connected and
configured to utilize a PowerVault MD storage array and provide NAS services. PowerVault FluidFS
systems can start with one NX36x0 appliance, and expand with another (identical) appliance as required.
