Configuration and Hardware Options Guide v
Preface
How to Use This Guide
This guide provides information and assistance to system or network
administrators preparing for the installation of a SnapServer storage system on
their network. Every network topology is different, and every administrator works
with different goals and resources. Using this guide, administrators can determine
what additional hardware components or software packages and licenses to acquire
before the server arrives.
Hardware Components
SnapServers come with the hardware required to install the server into an EIA-
compliant rack (if applicable), as well as the cables required to connect the server to
a power source and to an Ethernet network. Other hardware required for a basic
installation, such as Ethernet switches, racks, and UPS devices, must be supplied by
the administrator from third-party vendors.
Some advanced configurations involving expansion arrays or direct-attached tape
backup may require the separate purchase of SAS, SCSI, or FC-HBA cards from an
authorized Overland Storage reseller. The hardware checklists in this guide show
the required and optional hardware components available for each SnapServer
model.
Software Components
SnapServers also come with native support for partner-vendor software packages
that enhance or extend the functionality and security of SnapServers. These
packages include antivirus, backup, and administrative software. Some of these
software components are simply provided as part of your SnapServer purchase;
others perform at baseline functionality that can be upgraded as necessary; and
some require the purchase of a license to become operational. SnapServers are also
compatible with a number of widely-used third-party backup solutions.
This guide briefly describes these software packages and provides information on
licensing or upgrade procedures. For full descriptions and specifications, see the
SnapServer, partner-vendor, or third-party vendor Web sites as appropriate.

SnapServer and Expansion
Array Hardware Components
All rack-mountable SnapServers and expansion arrays come with the cables and
hardware required to install them into a rack and connect them to the network or
other SnapServer storage products. Customers supply the rack, Ethernet switches,
UPS devices, and any backup devices such as a tape library.
The performance and functionality of the SnapServer can be enhanced through the
installation of additional hardware components. A SCSI card can be installed in the
SnapServer 410, 510, 620, N2000, 4200, and 4500 for attaching tape backup devices.
Additional RAM can also be installed to the SnapServer 510, 520, 550, 620, 650.
N2000, 4200, and 4500. Your SnapServer 520, 620, N2000, 4200, 4500, and 18000’s
capacity can be increased through the installation of an expansion array controller
card and the attachment of one or more expansion arrays (SAS cards come pre-
installed in your SnapServer 550, 650, and N2000). If your SnapServer EXP E2000 or
Snap Expansion S50 expansion array came with less than the maximum number of
drives, it can be upgraded to increase available capacity. The number of Ethernet
ports on the SnapServer 520, 550, 620, and 650 can be increased to four with the
installation of the Ethernet PCI adapter. The SnapServer NAS N2000 can increase
the number of Ethernet ports to six.
• Use only internal hardware components qualified by Overland Storage —
Overland Storage strongly recommends that you use only qualified components
from authorized Overland Storage resellers. Qualified means that Overland
Storage technicians have tested and verified that the component operates
properly with the SnapServer and other network components. Failure to use
qualified components may seriously impact data availability, could potentially
lead to data loss and corruption, and will void your warranty.
• Standardize on a single vendor for external hardware components — Not only
will standardization on a single vendor minimize the chance of unforeseen
interoperability failures, it will also simplify troubleshooting procedures.
Notes (1) For a complete list of qualified components, including replacement parts
and installation instructions, go to http://www.snapserver.com and navigate to
your server model; (2) To find an authorized reseller in your area, go to http://
www.snapserver.com and click the How to Buy tab.

Safety Precautions
2 Configuration and Hardware Options Guide
Safety Precautions
• Environmental Conditions — Make sure the physical environment in which the
unit resides falls within the specifications for your model as described in this
guide.
• Installing the Server or Expansion Array — During installation, make sure the
unit is always placed on a surface capable of supporting its weight.
• Connecting to the Main Power — Install the unit near an easily accessible power
source. Make sure the source is the proper voltage for your model. Place the
power cord(s) out of the way of traffic; do not place any object over the power
cord(s). If the unit is taken offline for an extended period, disconnect it from the
power source to avoid possible damage from a power surge.
