Server-to-Server Synchronization Release Notes
|
|
| About S2S |
| Server-to-Server Synchronization (S2S) is Java-based data replication
software that copies the contents of a share from one (source) Snap Server
to share on one or more different (destination) Snap Servers. S2S works
on all Snap Servers other than Snap Servers 1000 and 4000. This document
contains information on the following topics: |
 |
Software requirements — In addition
to the S2S software, you may need to upgrade your Snap Server to the latest
SnapOS and the Virtual Machine. |
|
Installing S2S and related software
— Procedures for downloading and installing the software components. |
|
Activating the software
— After you install the S2S software, use the browser-based Administration
Tool to activate S2S. |
|
Port Utilization — Information
on the ports used for S2S operations. |
|
Known issues — S2S
operations are configured using a browser-based Java interface. Some minor
issues with the interface related to MS Internet Explorer, Netscape Navigator,
and the Mac OS are discussed. |
| Software Requirements |
|
In addition to the Server-to-Server Synchronization software itself,
the current version of several other software components is required.
Each component is available for download from the Snap Appliance Web site.
|
|
Current Snap Operating System — SnapOS v4.0 or higher.
The Upgrade Guide provide procedures for
identifying your SnapOS version and for upgrading your Snap Server to
the latest version of the SnapOS. |
|
Java Support Software — The Virtual Machine is a software
module that allows you to use SnapExtensions such as Server-to-Server Synchronization
and other applications based on Java™ technology. |
| |
Tip If your Snap Server came with SnapOS v3.4.790
or higher installed (i.e., you did not upgrade to this version), the current
Virtual Machine (VM) is already installed on your server. If you upgraded
to SnapOS v3.4.x using a *.sup file downloaded from the Snap Appliance Web
site, you will need to download and install
the current version of the VM. |
|
Snap Server 2000 Only — Snap Server 2000 models (only)
must have hardware version 2.0.0 or later to use Server-to-Server Synchronization.
To identify the hardware version, click the logo in the upper left
corner of the browser-based Administration Tool. A window opens, displaying
the hardware version number. |
| Installation Utilities |
|
Assist — If your Snap Server currently runs a version
of the SnapOS prior to 3.4.x, you must use the Assist administrative utility
to perform the SnapOS upgrade. The Assist utility is available from your
User CD or from the Snap Appliance Web site. Information on using Assist
can be found in your administrator guide. |
|
Administration Tool — The browser-based Administration
Tool is used to install the Virtual Machine and the S2S software. The current
version of the Administration Tool is part of the SnapOS upgrade package
and is automatically installed during the SnapOS upgrade procedure. |
| Downloading and Installing
S2S and Related Software Components |
| Caution The software components must be installed

| 1 |
SnapOS update file(s) |
| 2 |
Snap Server Virtual Machine software |
| 3 |
S2S software |
| Step 1: Downloading the Software Components |
| Before beginning the installation procedures, download
all the necessary software components from http://www.snapappliance.com/download.
To access the software download section of the Web site, you will need the
e-mail address that was used to register your products. Save the components
to a local system that has access to the Snap Server. |
| Step 2: Upgrading to SnapOS v4.0 or Higher |
| SnapOS upgrade procedures vary according to the current
version of the SnapOS you are running. |
| Step 3: Upgrading the Virtual Machine
|
| After upgrading the SnapOS, upgrade
the Virtual Machine. |
| Step 4: Installing S2S |
| 1 |
If necessary, download the upgrade file (Snap_ServerSync.sup)
from http://www.snapappliance.com/download
and save it on a local system. |
| 2 |
Connect to the Snap Server via the browser-based Administration
Tool, logging in as the administrator. |
| 3 |
Navigate to the Server Settings > OS Update screen. |
| 4 |
Use the Browse button to navigate to and select the
Snap_ServerSync.sup file. |
| 5 |
Click OK to begin the update process. |
| |
Once the update process is complete, you will be prompted
to reboot the server. |
| Activating the Software |
| After the installation of the S2S software, use the
browser-based Administration Tool to enable the VM and activate the S2S
software. |
| Enabling the Virtual Machine |
| 1 |
Connect to the Snap Server via the browser-based Administration
Tool, logging in as the administrator, and click SnapExtensions. |
| 2 |
Click Start Java to start the Virtual Machine. |
| 3 |
On the confirmation screen, click Yes to restart the
Snap Server with the virtual machine enabled. |
| Enabling S2S |
| 1 |
Connect to the Snap Server via the browser-based Administration
Tool, logging in as the administrator, and click SnapExtensions. |
| 2 |
Enter the S2S license key provided at the time you purchased
the S2S software, and click OK. |
| |
The screen refreshes, displaying controls to start and stop
the software. |
| 3 |
Click Server-to-Server Synchronization to activate
the S2S software. |
|
| Known Issues |
| Please note the following information regarding OS and browser
support for Server-to-Server synchronization. |
|
Non-English Character Support — The Java Virtual
Machine supports the first 128 characters of the English code pages (850,
437, 865, 1252) and will not transfer files that use other characters. File
names that contain characters not found in standard English will cause S2S
operations to fail. |
|
Internet Explorer Users — To administer S2S from a
Windows client running Internet Explorer, install the latest version of
the Microsoft Virtual Machine on the client. Previous versions of the Microsoft
Virtual Machine displayed blank dialog boxes and did not properly run the
Server-to-Server Synchronization applet. If you experience any problems
with Server-to-Server Synchronization, install the Microsoft Virtual Machine
upgrade, which can be found at the Microsoft Web site. |
|
Netscape Communicator Users — To administer S2S from
a client running Netscape Communicator, you must use either version 4.7x,
or version 6.1x or higher. (Navigator v6.0x does not properly support Server-to-Server
Synchronization.) Note also that to use Navigator v6.1x, you must disable
the Snap Server SSL option. |
|
Macintosh Users — To administer S2S from a Macintosh
client, install Mac OS X v10.1 or higher. Previous versions of the MacOS
did not properly support Java-based applets such as S2S. |
|
| Port Utilization |
| Server-to-Server Synchronization uses the following
ports: |
|
TCP/IP 9090, 9092, and 9093
|
|
UDP 4466
|
| If there is a firewall in between the source and destination
Snap Servers, the firewall must be configured to allow open communication
through these ports. Another alternative is to put both the source and destination
Snap Servers behind the same firewall, thus eliminating the need to open
the ports. |
