Introduction
SNAZ network attached file servers
The SNAZ family of network attach file servers (NAS) provide robust
and easily managed file serving for departmental, branch office and
medium sized company applications.
• S4-350 is a 1U 19 inch rack mount unit with 4 drive bays
offering user storage of between 750GB and 1.5TB (Usable
Capacity using RAID 5; the S4-350 is configured without a hot
spare)
• S8-350 is a 2U 19inch rack mount unit with 8 drive bays
offering user storage of up to 2TB (Usable Capacity using RAID
5). For larger capacity requirements, the associated 2U SNAZ

System menu
The System menu allows you to access:
• Status (home) page - see System status on page 11
• Time & Date
• Services - see page 15
• Software Update - see page 23
• Notification - see page 24.
Time & Date
The System - Time & Date page allows you to:
• Set the time and date manually
• Synchronize the system’s time with a Network Time Protocol
(NTP) Server.
To set the time and date manually:
1 From the menu bar, select System - Time & Date.
2 Use the drop-down menus to select a Time Zone from the list.
3 If appropriate, tick the box for Daylight Saving time.
97707987 Rev A 13
4 Set the Date, you can either type in the date in the format
YYYY/MM/DD (e.g. 2006/07/24 for the 24th July 2006) or click
on the calendar icon ( ) to show the Select Date pop-up:
5 Set the Time in the format Hour(s), Minute(s) and Second(s).

Synchronising the time and date with an NTP server
To set the time and date using an NTP server:
1 From the menu bar, select System - Time & Date.
2 Tick the Automatically synchronize with Internet time
server box and enter an NTP server URL to automatically
synchronize the time with an Internet time server.
You can test the connection to the NTP server by clicking
.
Note: If you are using a SNAZ and an Active Directory Server, it
is essential that their system time be synchronised. We
recommend that the same NTP server is used for both the SNAZ
and the Active Directory Server.
3 Click to save the changes.

Services
The System - Services page allows you to start, stop and, in some
cases, configure:
• MS Networking - see page 16
• NFS - This is configured via the Network - Shares page - see
page 37
• FTP - see page 23
• Replication - This is configured via the Data Protection -
Replication Target page - see page 63
• UPS - see page 20
• Backup - see page 22.
97707987 Rev A 15
MS Networking
To configure MS Networking:
1 From the menu bar, select System - Services and click on MS
Networking. The MS Networking (Configuration) page
opens:
2 Enter a Server Description. This is a name (or type)
description for the server.
3 If required, enter a Connection Timeout in minutes. This is
the amount of time that connections may remain idle, with no
open files, before disconnecting them from the share. The
default timeout is 30 minutes.
4 If required, enter a WINS Server ID. This is the IP address of
the Windows Internet Naming Service (WINS) server.
5 If required, enter the number of Max Sessions. This is the
maximum number of concurrent MS Networking sessions that
the SNAZ will accept. The default is 60 sessions.
6 Select whether MS Networking connects:
• Using all available interfaces - to use any and all
available network ports
• Using the following interfaces - to use a network port
specified from the drop-down list.
7 Click on the Security tab. This gives access to the Active
Directory Server user authentication features.
16 97707987 Rev A
8 If required, enter a Workgroup.
OR
Enter a Domain Name. This is the domain name the MS
Networking service will use and is not the same as a DNS
domain name.
9 If required, enter the name of the Organization Unit (OU)
within the Active Directory structure in which the SNAZ will
appear. By default, the server will appear within the OU
named “Computers”.
10 If required, enter the Windows User Name. If a Windows User
Name is entered, their Password must be supplied.
11 The Domain Type is derived from the connection to the
Active Directory Server. The two types of domain are:
• ADS (Win2K+)
• NT Compatible.
12 Click to save the changes.
97707987 Rev A 17
FTP
To configure FTP access to the SNAZ:
1 From the menu bar, select System - Services and click on FTP.
The FTP (Configuration) page opens:
2 If required, enter an FTP Server Banner. This is a message
which will be displayed to users when they access the SNAZ via
FTP.
3 Enter a Data Mode. The data mode can be:
• PORT - The client connects from a random unprivileged
port (N > 1024) to the FTP server's command port, port 21.
Then, the client starts listening to port N+1 and sends the
FTP command PORT N+1 to the FTP server. The server will
then connect back to the client's specified data port from
its local data port, which is port 20
• PASV - The client initiates both connections to the server,
solving the problem of firewalls filtering the incoming
data port connection to the client from the server. When
opening an FTP connection, the client opens two random
unprivileged ports locally (N > 1024 and N+1). The first port
contacts the server on port 21, but instead of then issuing a
PORT command and allowing the server to connect back to
its data port, the client will issue the PASV command. The
result of this is that the server then opens a random
unprivileged port (P > 1024) and sends the PORT P
command back to the client. The client then initiates the
connection from port N+1 to port P on the server to
transfer data
• BOTH - The FTP client defines the connection method
(PORT or PASV) and the server responds accordingly.
4 Enter a Connection Timeout. This defines how long the SNAZ
should remain connected, but idle, before disconnecting.
18 97707987 Rev A
The timeout settings for connections are:
• 30 seconds for Short
• 60 seconds for Medium
• 300 seconds for Long.
The timeout settings for transfers are:
• 150 seconds for Short
• 300 seconds for Medium
• 1500 seconds for Long.
5 Enter Max Clients. This is the maximum number of concurrent
FTP client connections.
6 Enter Max Clients per IP. This is the maximum number of
concurrent FTP client connections per IP address.
7 Enter the Max Transfer Rate. This is the maximum rate, in
Bytes, of FTP data transfer.
8 Click on the Security tab. This allows you to enter IP addresses
and/or hostnames which you wish to explicitly Allow or Deny
FTP access to the SNAZ.
Note: When hosts are added to either the Allow or Deny lists, all
other hosts automatically become marked as the opposite, unless
they are specified otherwise.
9 Click to save the changes and, as appropriate, click
to start or click to stop the service.
97707987 Rev A 19
UPS
The information in the System - Services - UPS page is derived
from the UPS itself.
Refer to your UPS’s documentation for further details.
Note: The SNAZ only supports APC Smart brand UPSs.
1 From the menu bar, select System - Services and click on
UPS. The UPS (Status) page opens:
• UPS Model - The type of UPS attached to the SNAZ
• Status - The UPS's status (e.g ONLINE,)
• Line Voltage - The UPS's input voltage
• Battery Charge - The amount of battery charge, in
percent, remaining
• Battery Time Left - The amount of battery charge, in
minutes, remaining
• Output Voltage - The UPS's output voltage (to the SNAZ)
• UPS Temperature - The temperature of the UPS enclosure
• Last time power was transferred to UPS - The last time
the power was transferred from the mains supply to the
UPS.
