Introduction

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

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 four 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 these main advantages to your business:

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

different 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 users on your network.

• Data Consolidation: Centralize data to reduce management costs and

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

Cisco Small Business NSS3000 Series Network Storage System Administration Guide 1

Introduction

Using the Help

Using the Help

1

The NSS help file provides information about using the configuration interface to
configure the NSS.

Audience

The information contained in the 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 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 Top ic page in the right
side of the window.

• Topic Page: 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 window that you can click to
access the 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.

• 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.

Cisco Small Business NSS3000 Series Network Storage System Administration Guide 2

Introduction

Using the Quick Setup Wizards to Configure the NSS

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 Time.

We recommend that you do not use the Refresh button on the Web browser
toolbar as this can cause data issues.

Using the Quick Setup Wizards to Configure the NSS

There are three wizards available from the Manager Menu of the configuration
interface. Select the wizard and then follow the onscreen instructions.

1

• Initial Setup: 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, 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. The NSS then reboots and the 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.

• IP Camera Options: The FTP and CIFS wizards let you set up the NSS to

store videos from IP surveillance cameras. The type of wizard you choose
depends on the way the camera transfers the video clips.

NOTE You only need to run the wizard once and then you must configure

each camera to output the video to the configured share.

When running either of the wizards make sure that you create a RAID array,
a volume, and any users that you want to grant access to the surveillance
videos. After running the 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.

Cisco Small Business NSS3000 Series Network Storage System Administration Guide 3

Introduction

Approved Vendor List for Drives

1

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

triggered clips through FTP. Running the wizard creates a single user and
FTP share for the cameras. The videos are then saved within the FTP
share which contains a subfolder dedicated to each camera. After you
run the wizard, you must configure each camera to output the video to
the configured NSS share. Use the information summarized on the last
page of the wizard to set up the cameras through their configuration
interface.

- 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
stream video to the Windows camera 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 and then set up the utility to
save to the mapped network drive.

Approved Vendor List for Drives

If you are purchasing disk drives to install in the NSS, see the Approved Vendor
List at www.cisco.com/go/smallbiz 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 NSS3000 Series Network Storage System Administration Guide 4

Managing the System

The NSS3000 lets you view status details from two locations: the LCD panel on
the front of the chassis, or from the Configuration Interface. See ”About the NSS

Configuration Interface” on page 2. The LCD lets you view some of the status

information such as the hostname, IP address, netmask system alerts, RAID status,
volume status, cable diagnostics, time and date, firmware version and firmware
upgrade status, and bootup and shutdown status.

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.

The following sections describe the information that appears on the System
Status page.

The System Alerts section shows any system messages issued since the last
time they were cleared. Messages can range in severity from informational to
immediate action required.

There are three type of alerts that can appear:

• Error: Indicates the most severe types of problems with the NSS. They

require immediate action. For example, if a disk drive or RAID array is in a
failed condition.

Storage Status

• Warning: Indicates that 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.

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

• Drives: The number of physical disk drives installed.

• RAID Arrays: The number of configured RAID arrays.

• Volume s : The number of configured volumes.
