1Overview
This manual describes how to use the Overland Storage SnapSAN S2000 system. The
appliance together with the SnapSAN S2000 software provides a flexible, intelligent,
iSCSI-based storage area network (SAN) solution for virtualized server environments
and the growing demand for data storage. With a SnapSAN S2000 appliance, you can
store, share, protect, and manage data through a single easy-to-use Windows or web
interface.
SnapSAN S2000 Overview
The SnapSAN S2000 has two main components: the appliance and its custom
software.
SnapSAN S2000 Appliance
This is a appliance connected to your local storage area network running the
SnapSAN S2000 software. The appliance manages a RAID controller which, in turn,
manages the physical operation of a group of hard disks. The S2000 makes this
networked disk storage look just like one or more local disks.
SnapSAN Manager Suite Software
This is storage management software that enables you to manage your data storage
effectively and efficiently with no special knowledge about the underlying technology
required. There are two versions available:
•Windows SnapSAN Manager – A Windows program run from a network
computer.
•Web Management Interface – A web-based interface on the SnapSAN that is
accessed by a browser.

10400277-004 07/2011 ©2010-11 Overland Storage, Inc. W1-2
SnapSAN S2000 User Guide
The figure below illustrates how the SnapSAN S2000 software can map a set of
independent disk drives, connected to the network by a RAID controller, to a storage
pool from which seemingly “local” disks of user-defined size can be created and shared
by all the users on the network.
Windows SnapSAN Manager
The Windows SnapSAN Manager is a Windows program that provides you with an
easy way to manage your data storage. You can use it to perform the following storage
management tasks:
•Configure your appliance
•Create new disks from storage on the SnapSAN S2000 appliance.
•Protect the data by controlling shared access to it.
•Provide a high level of data security, using the built-in reliability that comes
with RAID technology.
•Monitor the way that data is used and then adapt the data storage to fit this
usage pattern, giving users optimal access to their data.
•Back up data quickly and efficiently using SnapSAN S2000 support for
snapshots, disk replication (optional), and mirroring (optional).
Web Management Interface
The Web Management Interface is a browser-based tool for managing your data
storage. You can use the Web Management Interface to perform the following storage
management tasks:
•Configure your appliance
•Create new disks from storage on a specific SnapSAN S2000 appliance.
•Check the logs for a specific SnapSAN S2000 appliance.
•Verify error or fault messages regarding a specific SnapSAN S2000 appliance.

SnapSAN S2000 User Guide
Recommended Drive Configurations
Before installing or adding drives to a SnapSAN S2000 appliance, the following must
be observed:
•Different capacity drives can be installed; however, they should not be included
in the same RAID array, because capacity usage for all drives in the RAID is
limited to the capacity of the smallest drive member.
•Drives of different rotational speed (such as, SAS and SATA drives) can be
installed, but they should not be installed in the same column. If you are
combining drives with different speeds, use the figures below to plan where to
place the disk drives.
SnapSAN S2000 Rack Installation Overview
WARNING: It is recommended that a mechanical lifter (or at least two people) be used
to raise and align the unit to prevent injury during installation. Use care when inserting
or removing a unit into or out of a rack to prevent the accidental tipping of the rack causing
damage or personal injury.
AVERTISSEMENT: il est recommandé que la mécanique lifter (ou au moins deux
personnes) soit utilisé pour élever et d'unifier l'appareil pour éviter des blessures
pendant l'installation. Faites attention lorsque vous insérer ou de retirer une unité d'entrée
ou de sortie d'un support pour empêcher le déversement accidentel de la crémaillère
causant des dommages ou des blessures.
CAUTION: Overland strongly recommends that you install the unit in a clean,
air-conditioned environment with power conditioning and an adequately rated
uninterruptible power supply (UPS). The unit is intended to be grounded.
Supported Configurations
Rotational Speed A Rotational Speed B Blank Disk Drive
Unsupported Configurations
Do not include drives
with different RPMs in
the same column.

Powering Up the SnapSAN S2000
The power switch is on the front panel located on the left side bracket. To turn the
appliance ON, press and hold the Power button for no more than one (1) second to
begin the power-up sequence.
After you turn the power ON, the System performs a self-test process, which takes a
couple of minutes.
After the unit completes the POST sequence, check the LED indicators on the left
bracket to verify the network connections are good.

3Initial Configuration
After installing a new SnapSAN S2000 appliance, there are two ways to handle the
initial configuration of an appliance:
•A Windows program (Windows SnapSAN Manager) is installed as part of the
SnapSAN Manager Suite on a network computer and can be used to configure
any SnapSAN S2000 appliance on the network (“Using the Windows SnapSAN
Manager”). This is the recommended procedure.
•The web interface (Web Management Interface) can be accessed by a browser to
configure and operate that specific appliance (“Using the Web Management
Interface” on page 3-10). This can be used by any OS such as Linux or Mac.
Using the Windows SnapSAN Manager
Before you can use the Windows SnapSAN Manager, you must make sure an iSCSI
initiator is installed on each Windows host and the SnapSAN Manager Suite software
has been installed.
Installing an iSCSI Initiator
An iSCSI initiator must be installed on each Windows host to access the storage
managed by the Windows SnapSAN Manager.
Windows Server 2003 and XP operating systems do not include an iSCSI initiator as
standard, but the Microsoft iSCSI initiator is available as a free download. To find the
initiator, go to http://www.microsoft.com/downloads and search for iSCSI. Follow the
installation instructions that come with the initiator.
If you plan to use a different initiator, follow the instructions provided with it.
Installing SnapSAN Manager Suite Software
NOTE: The SnapSAN Manager Suite software can only be installed by the Administrator or a
user with Administrator privileges.
The SnapSAN S2000 SnapSAN Manager Suite files along with electronic copies of all
the important documents are available from download from the Overland SnapSAN
website:

The installation procedure automatically configures the Windows Firewall to allow
Windows SnapSAN Manager and its Appliance Discovery Service to access TCP and
UDP port 4309 on your computer. If you are using SnapServer Manager (SSM), it
configures access to TCP and UDP port 111.
IMPORTANT: If you are using another firewall, open the firewall manually to allow the
Appliance Discovery Service and the Windows SnapSAN Manager incoming and
outgoing access on this port. If your system is behind a NAT interface, you will have to set up
port forwarding to your computer for this port.
NOTE: To install the SnapSAN Manager Suite on a VMware vSphere Client, refer to
Appendix D, “VMware Plug-In.”
Follow the on-window instructions to install the software:
1. Download the appropriate version of the SnapSAN Manager.
Choose either the 32- or 64-bit version from:
http://docs.overlandstorage.com/snapsan
2. Double-click setup.exe.
3. At the start window, click Next.

4. Review the license agreement, click the box to accept, and click Next to

8. At the completion window, click Finish to exit.
Once the SnapSAN Manager Suite is installed and you click Finish, the program
automatically launches the Windows SnapSAN Manager. Continue with
“Configuring the Appliance with Windows SnapSAN Manager.”
Configuring the Appliance with Windows SnapSAN Manager
To configure a SnapSAN S2000 appliance using Windows SnapSAN Manager:
1. If not already running, start the Windows SnapSAN Manager by selecting
Windows Start > All Programs > SnapSAN > SnapSAN Manager.
Automatically, Windows SnapSAN Manager tries to discover any appliances
that are connected to the network. During this discovery process, the Discovery
window is displayed and Windows SnapSAN Manager attempts to connect to
any SAN appliances it finds.
•If a connection succeeds, the SnapSAN Appliance Setup Wizard starts to
guide you through the setup process.
•If no appliances were discovered, the Windows SnapSAN Manager
Overview window will open. Recheck your network connections and verify
that the computer is on the same network as the SAN appliance.
