1-1 Tandberg Viking Series Storage Server Administration Manual
1. System Overview
1.1. Product Information
The Tandberg Viking Series NAS appliance can be used in many types of
computing environments, from basic Microsoft Windows workgroups to
complicated multi-protocol domains using DFS, NFS, FTP, HTTP, and
Microsoft SMB. The corresponding varieties of clients that can be serviced
include any Windows, UNIX, Linux, Novell, or Macintosh variant.
This chapter provides an overview of these environments and deployments
and includes brief descriptions of the available user interfaces. The Viking
Series NAS appliance is the disk-based storage for remote office or small to
medium business class NAS solutions that provide reliable performance,
manageability, and fault tolerance.
The Viking Series NAS appliance provides performance gains over general
purpose servers by integrating optimized hardware components and
specialized operating software. Integrating NAS appliance into the network
improves the performance of existing servers because NAS appliances are
optimized for file serving tasks.
Notes
The Viking Series NAS appliance has been specifically designed to function as a
Network Attached Storage server. Except as specifically authorized by Tandberg
Data, you may not use the server software to support additional applications or
significant functionality other than system utilities or server resource management
or similar software that you may install and use solely for system administration,
system performance enhancement, and/or preventative maintenance of the
appliance.
Your Viking Series NAS appliance comes preinstalled with either the Windows®
Storage Server™ 2003 R2 operating system (32-bit version) or the Microsoft®
Windows® Unified Data Storage Server 2003, Enterprise x64 Edition operating
system.
Microsoft Windows Storage Server 2003 R2 extends the Windows Storage
Server 2003 operating system, providing a more efficient way to manage and
control access to local and remote resources. In addition, Windows Storage
Server 2003 R2 provides a scalable, security-enhanced Web platform for
simplified branch server management, improved identity and access
management, and more efficient
storage management.

Tandberg Data System Overview

1-2 Tandberg Viking Series Storage Server Administration Manual
Notes
The Microsoft® Windows® Storage Server 2003 x64 Edition operating system is
designed to support 32–bit applications without modification; however, any 32–bit
applications that are run on this operating system should be thoroughly tested
before releasing the storage server to a production environment.
Microsoft® Windows® Unified Data Storage Server 2003, Enterprise x64 Edition
operating system provides unified storage server management capabilities,
simplified setup and management of storage and shared folders, and support for
Microsoft iSCSI Software Target.
Notes
For more information about Microsoft® Windows® Unified Data Storage Server
2003 operating system, see “Using iSCSI Software Target” on chapter 9.
1.1.1. Product Manageability
The Viking Series NAS appliance ships with the following utilities and
features that ease the administration tasks associated with managing the
system:
•The Recovery Disc (factory image) contains the preconfigured default
settings of either the Windows Storage Server 2003 R2 operating system
or the Microsoft® Windows® Unified Data Storage Server 2003 operating
system. This is a quick and easy way to setup or bring the Viking Series
NAS appliances back to the factory default configuration.
•Using the Windows Remote Desktop client to establish
administrative session with the appliance without physically
connecting to it.
•Ability to connect directly to the NAS appliance’s console.
1.2. Redundancy
The Viking Series NAS appliance is specifically designed to perform file
serving tasks for networks, using industry standard components to ensure
reliability. Other industry standard features, such as redundant array of
independent drives (RAID) and remote manageability, further enhance the
overall dependability of the NAS appliance.
To ensure redundancy and reliability, it is recommended that the hard drives
installed in the Viking Series NAS appliance are configured so that a single
drive failure will not cause data loss or system failure.
Depending on the model of Viking Series NAS used, it is capable of support
from 4 HDD to 16 HDD in a single chassis:
•Viking FS-412 supports up to 4 HDD (1U)
•Viking FS-1600 / FS-1610 supports up to 16 HDD (3U)

1.2.1. Configuring RAID using 4 HDD (1U)
For the 1U appliance (FS-412) Tandberg Data recommends two logical
Volume sets consisting of System Volume (SV) and Data Volume (DV) to be
created within the RAID set. The RAID set is first created which comprises of
member HDD (number of HDD in a set). The two logical volumes (SV and
DV) are then allocated from aggregated capacity of the RAID set with the
desired RAID levels. The System Volume, installed with the host operating
system, is organized as RAID 0+1 and the Data Volume is organized as
RAID 5. This is to allow OS redundancy if more than one HDD fails. Please
see the Viking Series NAS Hardware User Manual for details.
The volume layout for the appliance is illustrated below.

1.2.2. Configuring RAID using 16 HDD (3U)
The 3U appliance uses (FS-1600 / FS-1610) supports up to a maximum of
16 HDD. This provides greater degree of flexibility in RAID configurations:
•Allow HDD to be grouped into multiple RAID sets with respect to
their usage role: System Volume, Data Volume(s) or RAW Volumes
(for iSCSI target volume provisioning). HDD of differing capacity can
also be grouped into similar RAID sets.
•Assigning unused HDD as hot-spares.
•Multiple RAID level support on Volume sets.
Depending on the number of HDD used and their capacity, the RAID Set
grouping and the RAID level of each Volume Set is easily customizable.
Below is a working example:
Using 16 HDD in which 4 is 750GB and 12 is 1,000GB in capacity. The HDD
can be grouped into their respective RAID Set:
RAID Set#00 is created to house the OS as well as a File-system for
sharing. Volume Set#00 is created with RAID level 0+1 which contains a
usable capacity of 200GB. The remaining RAID Set#00 capacity is sliced
into Volume Set#01 of RAID level 5 that yield a resultant capacity of
1,950GB. Volume Set#00 is the System Volume (SV) and Volume Set#01 is
the Data Volume (DV).
•RAID Set#00 = 4 x 750GB
•Volume Set#00 = 200GB (RAID 0+1) SV
•Volume Set#01 = 1,950GB (RAID 5) DV
RAID Set#01 is created with iSCSI target LUN provisioning in mind. Ten (10)
of the 1,000GB HDD are grouped into RAID Set#01 and Volume Set#00 of
RAID level 6 is created out of it. This yields a usable capacity of 8,000GB
after the RAID 6 overhead.
•RAID Set#01 = 10 x 1000GB
•Volume Set#00 = 8,000GB (RAID 6)
The remaining two (2) of the 1,000GB HDD are set as hot-spares.
•Hot-spare = 2 x 1,000GB
The hot-spare can be assigned to any degraded RAID Set for rebuilding in
event that one (or more) of its member disk have failed.
Notes
While assigning hot-spare to a degraded RAID Set, ensure that the capacity of the
hot-spare must be equal or greater than the lowest capacity of the member disk of
that RAID Set.
