Redundant Dual Active
Controller
(RDAC)/Multi-Path Proxy
(MPP)
A multi-path failover driver, proprietary to NetApp, that is installed on
Linux hosts. This software package manages the I/O paths into the
controllers in the storage array. If a problem exists on the path or a
failure occurs on one of the controllers, the driver automatically
reroutes the request from the hosts to the other controller in the storage
array. For information about other supported failover drivers for your
operating system, refer to the topics under SANtricity ES Storage
Manager Failover Drivers User Guide for Version 10.86.
SMutil This package contains utilities that let the operating system recognize
the volumes that you create in the storage array and to view the
OS-specific device names for each volume.
SMprovider The storage management software interface to the Volume Shadow
Copy Service (VSS) and Virtual Disk Service (VDS) technologies
(these technologies are included with Microsoft’s .NET framework).
SMinstaller A package that installs the InstallAnywhere utility.

In-band management is a method for managing a storage array in which the controllers are
managed from a storage management station attached to a host that is running host-agent software.
The host-agent software receives communication from the storage management client software and
passes it to the storage array controllers along the input/output (I/O) path. The controllers also use the
I/O connections to send event information back to the storage management station through the host.
