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.
NOTE The Microsoft Virtual Disk Service (VDS) and Volume Shadow Copy Service
(VSS) providers are a part of the SANtricity ES Storage Manager package for the
Windows Server 2003 OS and the Windows Server 2008 OS.
Description and Usage
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 10.83.
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.
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).
A package that installs the InstallAnywhere utility.
