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
3
If required, enter an FTP Server Banner. This is a message
which will be displayed to users when they access the SNAZ via
FTP.
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.

Enter the Max Transfer Rate. This is the maximum rate, in
Bytes, of FTP data transfer.
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.

Shares on the SNAZ
Shares are used to give specified users controlled access to specific
folders and subfolders on the SNAZ system, from their client
computers.
This section does not detail how to create the individual
components of the Share (such as RAIDs and Volumes), it is intended
to demonstrate the process involved in creating a Share.
How a Share is created
Our example SNAZ system has a previously created RAID (called
RAID1), containing a Volume (called Volume1):
Our example SNAZ system also has some users (called User2 and
User3), who are members of a group (called Group1).
From the Storage - Browse screen, the Volume looks like this:

Select a RAID Level from the drop-down list. This can be
either:
•
RAID 0 - RAID 0 is a striped disk array without fault
tolerance. Provides data striping (spreading out blocks of
each file across multiple disk drives) but no redundancy.
This improves performance but does not deliver fault
tolerance. If one drive fails then all data in the array is lost
•
•
RAID 1 - RAID 1 provides disk mirroring. Level 1 provides
twice the read transaction rate of single disks and the
same write transaction rate as single disks
RAID 5 - RAID 5 provides data striping at the byte level
and also stripe error correction information. This results in
excellent performance and good fault tolerance. Level 5 is
one of the most popular implementations of RAID.

Select a Chunk Size (KB) from the drop-down list. This is the

Data Backup
The Data Protection - Data Backup page lists information
required to configure the BakBone NetVault backup software, as
follows:
Definitions
The SNAZ has both a NetVault Server and Client running on it:
•
•
NetVault Server - controls the backup process
NetVault Client - accesses the data which is to be backed up.
A separate PC is used to run the NetVault GUI, which is used to
administer the backup process.
Note: The NetVault GUI must be installed as a Server.
Licensing
A full BakBone NetVault License Key must be entered for ongoing
operation of the backup utility.
The License Key will be emailed to you following registration via the
Plasmon Warranty Registration website. For further information
Backup Devices
Backup devices should be attached via the supplied U320 HD68 SCSI
interface on the rear of the SNAZ unit.
Note: SCSI termination of the backup device(s) may be necessary.
Refer to the backup device manufacturer's documentation for
further details.
Confirmation that the backup device(s), either as a stand alone tape
drive or an Autoloader comprising the Autoloader itself and a
number of drives, have been recognised by the system may found
via the Diagnostics - Storage Devices page.
