Introduction

Thank you for choosing the Cisco Small Business Network Storage System (NSS).

Administering a network can be a difficult job. Finding low-cost ways to simplify
your data-management tasks means that you have more resources to dedicate
elsewhere. The NSS is a Network Attached Storage (NAS) unit that appears as a
native file server for the various clients within your network, including Windows,
Apple Macintosh, UNIX, and Linux platforms. The biggest benefit to your users is
that they can now access data that might be stored across different physical
platforms as simply as if it were on their own computers. The NSS provides a
single repository that is completely dedicated to storage, ensuring the integrity,
reliability, and accessibility of your data for a relatively low cost.

The NSS lets you install up to two physical disk drives. The NSS uses the most
common file-based protocols such as NFS, CIFS, and FTP for file sharing.

1

Benefits

The NSS offers the following main advantages to your business:

• Cross-platform File Sharing: Share files easily and inexpensively across

heterogeneous platforms over a cost-effective Ethernet and IP network.

• Easy Installation and Administration: With a basic understanding of

networking, the NSS is easily configured, managed, and made available to
all of your networked users.

• Data Consolidation: Centralize data to reduce management costs and

maximize your investment in existing hardware. This also means better data
security.

The NSS2000 Series includes the NSS2000 and NSS2050 models. Check
www.cisco.com/go/smallbiz for additional information.

Introduction

Using the Help

Using the Help

1

The NSS (Network Storage System) help file provides information about using the
configuration interface to configure the NSS.

Audience

The information contained in these help pages is intended for use by network
administrators. It assumes a basic understanding of storage-related concepts,
including RAID, filesystems, and networking.

About the NSS Configuration Interface

The NSS configuration interface contains some basic navigation features to help
you as you configure the NSS.

• Manager Menu: The Manager Menu forms the left side of the configuration

interface window. It contains the menu options that represent the major
configuration areas for the NSS. For example, System, Network, Share,
Storage. When you click an option, a sub-menu of related options appears.
Clicking a topic opens the associated topic in the To p i c page in the right
side of the window.

• To p ic Pa g e: When you select a topic from the Manager Menu, the

configuration page for that topic appears in the right side of the window.

Getting Help

There are two buttons on the NSS configuration interface window that you can
click to access help:

• From the Manager Menu click Help to display the full online Administrator

Guide. Use the navigation tools within the help to find information for your
chosen topic.

Cisco Small Business NSS2000 Series Administration Guide 2

Introduction

Using the Help

1

• A context-sensitive help button appears in the upper-right corner of the

topic page. Click it to display help on the specific configuration area. For
example, if the current configuration topic is about the status of your
system, click the Help button for information about the details that appear
on the System Status page.

Refreshing the GUI Pages

Although certain GUI pages automatically refresh at a preselected time interval,
some pages do not refresh until they are reselected. The best way to manually
refresh a GUI page is to reselect it through the options in the Manager Menu on the
left side of the GUI window. For example, to refresh the NTP Configuration page,
from the Manager Menu, click Admin and then click Tim e. We recommend you do
not use the Refresh button on the Web browser toolbar as this can cause data
issues.

Cisco Small Business NSS2000 Series Administration Guide 3

Introduction

Using the Quick Setup Wizards

Using the Quick Setup Wizards

There are three wizards available from the Manager Menu of the configuration
interface:

• Initial Setup: This wizard automatically appears when you log into the

configuration interface for the first time. Although you can access it at any
time from the Manager Menu, if you have saved any configuration settings
before you run the wizard, note that running the wizard will erase any saved
data. For example, if you configure a RAID and then run the wizard, the RAID
will be deleted. This wizard steps you through the basic configuration to
create a RAID, volume, share, user, to set the Home Directory location, set
the time, and so on. (For detailed help on the full set of configuration options,
refer to the online help or to the Administrator’s Guide which you can
download from the Cisco website.)

1

• IP Camera Options: The following wizards let you set up the NSS to store

videos from IP surveillance cameras. The type of wizard you should choose
depends on the way the camera transfers the video clips. Note that you only
need to run the wizard once and then you must configure each the camera
to output the video to the configured share. To run either of the following
wizards, make sure you have created a RAID array, a volume, and any users
that you want to grant access to the surveillance videos. After running this
wizard, you must map a network drive to the share on the PC running the
camera utility and configure the camera utility to save the video to this
mapped network drive

- FTP: Run this wizard if the cameras are set up to transfer motion-

triggered clips. Running the wizard creates a single user and FTP share
for the cameras. The videos are then saved within an FTP folder which
contains a subfolder for each camera.

- CIFS: Run this wizard if the cameras have a Windows utility program that

lets you save the streaming video to a local drive (or in this case, the
NSS) and then view the video from its saved location. The wizard
creates a single user and share for all cameras that are configured to
output to the Windows Utility program. After you run the wizard, you
must map the network drive from the PC that runs the Windows utility
program to the CIFS share.

Introduction

Approved Vendor List for Drives

Approved Vendor List for Drives

If you are purchasing disk drives to install in the NSS, refer to the product support
information offered on the Cisco website (www.cisco.com) for a list of
recommended disk drives.

When you select a disk drive, consider the type of RAID levels required to service
your business needs. For example, if you are creating a RAID (versus a JBOD),
make sure that each of the disks used in the array have the same disk capacity.
The RAID is built using the capacity of the smallest disk in the array.

Cisco Small Business NSS2000 Series Administration Guide 5

Managing the System

The System Status page provides an overview of the current operating condition
of the NSS. For example, you can view system alert messages such as if a disk
drive is failing or has failed, if a volume is approaching its full capacity, and if an
array rebuild is complete. You can also view the current status of any of the
following: storage, shares, backups, network, power, and system details. Status
pages like the System Status page automatically refresh on a regular interval and
are helpful for monitoring the progress of certain processes such as building a
RAID.

problems with the NSS. They require immediate action. For example, if a
disk drive or RAID array is in a failed condition.

• Warning: These types of messages indicate there is a problem with the

NSS that requires eventual action. For example, if the amount of storage
used for a volume is over 90%.

• Notification: These types of messages are simply to advise of changes to

the NSS. For example, the RAID rebuild is complete.

Storage Status

The Storage area displays details about the configured storage on the NSS,
including:

• Drives: The number of physical disk drives installed.

Viewing VLANs Configured on the NSS

When you first display the Network VLAN page, the currently configured VLANs
appear. Configuring a VLAN to connect to the NSS depends if it is trunk-based or
port-based. To configure a trunk-based VLAN, follow the steps to allow a VLAN to
access the NSS; see ”Allowing a VLAN Access to the NSS” section on page 22. To
configure a port-based VLAN, configure the switch to assign the port to which the
NSS is connected to the desired VLAN. In this case, no NSS configuration changes
are required.

To view the VLANs currently configured on the NSS:

STEP 1 From the Manager Menu, click Network  VLAN.

• Priority: The quality of service (QoS) as defined in the IEEE 802.1p standard

for the VLAN traffic. VLAN Ethernet frames contain a three-bit priority tag
ranging from 0 to 7 (where 0 is best effort and 7 is network-critical traffic).

• Label: A text description for the VLAN (for example, "Data," "Voice," "Video,"

and so on). This description is used solely as a reference within the NSS
interface and does not affect its operation.
