The Access Logix software provides a secure, shared or selective access to the storage volumes in
both mixed and homogeneous platform environments.
The SnapView software is a non disruptive backup and recover enabler that facilitates increased data
availability. It provides a point in time image of information stored on a CX400, maintaining a view of
the data at the desired point and allowing access to that view for other uses such as backup or
application testing . CX400 supports up to 150 active snapshots with the ability to generate eight
snapshots per LUN. An additionnal host is requested on AIX to run the application using the snapshot
copies.
The MirrorView software provides highly available data storage across several CX400, CX600 and
DAS4700, possibly at separate locations. By maintaining synchronous data mirroring between the
arrays, MirrorView ensures data availability of byte for byte mirrored images. MirrorView is an array
base software so that hosts are not impacted by this feature. CX400 can support up to 50 mirrors.
CX400 supports also Powerpath that provides both load balancing to access data through the different
SP ports, and end to end failover capabilities. CX400 does not support ATF.
The CX400 can be shared by AIX and Windows servers using the [e-mail]! Manager. Support of mix
of AIX with other operating systems requires Access Logix.
Navisphere Manager Version 6 is mandatory to manage a CX400.
CX400 supports various operating systems environments : Windows, AIX, Solaris, HP-UX, Linux ,
Netware, …
