Data Mover virtual machines. The number of Data Movers varies by array size:
n
VMAX 100K = Two (default and maximum)
n
VMAX 200K = Two (default), or four (maximum)
n
VMAX 400K = Two (default), four, six, or eight (maximum)
All configurations include one standby Data Mover.

a.
Data movers are added in pairs and must support the same configuration.
b.
One I/O module per eNAS instance per standard block configuration.
c.
Backup to tape is optional and does not count as a possibility for the one I/O module
requirement.
Replication using eNAS
The following replication methods are available for eNAS file systems:
l
Asynchronous file system level replication using VNX Replicator for File.
Refer to
Using VNX Replicator 8.x
.
l
Synchronous replication with SRDF/S using File Auto Recovery (FAR) with the
optional File Auto Recover Manager (FARM).
l
Checkpoint (point-in-time, logical images of a production file system) creation and
management using VNX SnapSure.
Refer to
Using VNX SnapSure 8.x
.
eNAS replication is available as part of the Remote Replication Suite and Local
Replication Suite.
SRDF/A, SRDF/Metro, and TimeFinder are not available with eNAS.
