2Features
2.1 What is NAS ?
Network Attached Storage (NAS) solutions are defined as storage systems that are
directly hooked up to a network infrastructure. Also, they operate independently and
do not have to be connected to a server via a controller or host adapter. The term
“storage” here generally refers to all systems that either provide data storage or
actually store or organize data. Currently, data storage is the most common and most
widespread type of NAS systems.
NAS solutions are based on a separate operating system (and often also on special
hardware), which operates independently from the servers on a network. Typically, this
operating system is software that is optimized for providing data (file server).
NAS solutions allow users to add additional storage to existing networks quickly,
easily, and cost-efficiently.
2.2 Description of the functions
Open-E NAS-XSR is one of the easiest ways of implementing an NAS-XSR server in
your network. Through its simple architecture – in principal, it is a flash memory with
an IDE interface and Open-E NAS-XSR as its operating system – Open-E NAS-XSR
can be used with all x86 PCs containing an IDE controller and additional SATA
Controller on your main board or hardware controller.
To start working with Open-E NAS-XSR, all you need to do is assign an IP address to
the NAS server – either automatically through an existing DHCP server or by assigning
it manually. All other settings are handled via a web front-end which can be easily
accessed through the IP address of Open-E NAS-XSR using the encrypted https
protocol.
Open-E NAS-XSR allows users to create so-called shares (i.e., resources within a
network that numerous users or user groups have certain access too). The access
rights to the shares are controlled through the user and user group settings.
2.3 Why Open-E NAS-XSR?
Often, storage in network environments is expanded the following way: File servers
have to be shut down in order to install additional drives. In the next step, they need to
be reconfigured. In is tedious work data often has to be copied manually onto larger
drives, consuming a lot of time and money.
With Open-E NAS-XSR, you can add storage to your existing network quickly, easily,
and, most important, cost-efficiently. Expensive hardware is, therefore, no longer
necessary. Take any computer – a new rack server or an old desktop PC – and

8
exchange the system drive for the Open-E NAS-XSR flash module. To store data,
Open-E NAS-XSR uses IDE (ATA) and SATA hard drives, connected to ports on your
main board or hardware RAID controller.
Additionally NAS-XSR support software RAID, so you can create software RAID over
single hard drives or over existing hardware RAIDs.
For example, you can create software mirror over two hardware RAID5 for very high
reliability.
Within a few minutes, you will have up to several hundred gigabytes available on your
network – without much effort and any downtime.
2.4 RAID types
This manual is not intended to replace your RAID controller manual. But we want to
provide you with an overview of common RAID types so that you can make an
informed decision on which type to choose. Depending on whom you ask, RAID
means either Redundant Array of Independent Disks or Redundant Array of
Inexpensive Disks. Both are correct. In essence, you combine the capacity, speed and
security of several disks into one.
RAID 0 forms one large hard disk by concatenating stripes from each member drive.
Stripe size is configurable roughly between 64 KB and 1 MB. The result is a lightning-
fast RAID, but with no added security. One failing drive may ruin the entire RAID.
RAID 1 mirrors hard drives. By writing identical data onto more than one drive,
security is enhanced. A completely defective drive does not cause any loss of data.
The drawback is reduced performance and capacity.
RAID 5 combines data striping from RAID 0 with parity checking, therefore combining
speed and improved security. The loss of one drive is tolerable.
RAID 6 extends RAID 5 by adding an additional parity block, thus it uses block-level
striping with two parity blocks distributed across all member disks. It was not one of
the original RAID levels. The user capacity of a RAID 6 array is N-2, where N is the
total number of drives in the array. RAID 6 does not have a performance penalty for
read operations, but it does have a performance penalty on write operations due to
the overhead associated with the additional parity calculations.
RAID 10 is a combination of RAID 1 and 0, hence the name. Data is written in a
striped and mirrored configuration, providing high performance and robust security.

3Hardware installation
3.1 Getting ready
Switch off the computer, remove the power supply, and open the PC's enclosure. In
tower cases, the side parts often can be removed individually (on the backside of the
enclosure you just need to remove a few screws). Many machines have U- or O
shaped covers that have to be pulled off (either towards the front or the back). Should
you need any assistance, please contact your dealer.
Now localize the IDE connectors on your motherboard:
Every motherboard has at least two such ports. To install Open-E NAS-XSR, you have
to use the first (primary) port.
Often, the labeling on the IDE connectors may be tiny, but it is always there, on each
and every board. Preferably look for “IDE 0” If this connector does not exist, the first
port is called “IDE 1” (with the second connector being 2).
3.2 Installing Open-E NAS-XSR
If necessary, remove the flat band cable that connects your hard drive with the
controller. Open-E NAS-XSR should now carefully inserted into the connector. As IDE
ports can have a notch on one side, you can only insert the connector at the preset
position.

10
In the package you will find an adapter cable which provides Open-E NAS-XSR with
power. The little white plug corresponds with the matching connector on Open-E NAS-
XSR. As a final step, the adapter has to be connected to the white power-supply plug
(see photo):
That should conclude the installation! Before putting the enclosure on your computer
again, do not forget to connect your hard drives to the IDE second connector, SATA
connector or to the SATA port on the RAID controller. If you have a CD or DVD drive,
you can remove it, as Open-E NAS-XSR does not support optical hard drives, but if
you want to make an ISO update it is not necessary to remove the CD drives (see
5.2.3.4)

4Configuration
4.1 The basic configuration of the NAS-XSR computer
Connect your keyboard and a monitor to the NAS-XSR computer. You will only need
those devices for the basic configuration or extended maintenance configuration.
You may have to change the function “Halt On: All Errors” in your PC's BIOS,
so that the system starts even without the keyboard. The correct configuration
is “Halt On: All But Keyboard.”
4.2 First-time operation of Open-E NAS-XSR
Now start your system.
After booting is complete, Open-E NAS-XSR will provide you with information on the
current software version and the network settings:

If the network has a DHCP server, Open-E NAS-XSR should gain access to the IP
settings automatically. If that is the case, you can proceed at 4.3. If your network does
not have a DHCP server, Open-E NAS-XSR will start with the default settings: IP
address 192.168.0.220 and subnet mask 255.255.255.0.
You can change these values again by typing in the following key combination: left
CTRL, left ALT and N. You can select a different IP address now. All other available
functions on of the console will appear after pressing F1 key (see below).

After a connection has been established, all settings can also be changed remotely
via the web browser. If your network requires it, the address of the standard gateway
and the broadcast address can be changed.
For additional information, please read the chapter “Functions of the console
display.”
4.3 Logging into Open-E NAS-XSR ENTERPRISE
You can establish a connection to Open-E NAS-XSR from every network computer. To
establish this connection, use a browser (e.g. Microsoft Internet Explorer) and enter
the IP address or the name of the computer hosting the NAS-XSR server into the URL
entry line: https://192.168.0.220 (standard address) or https://ancom (this name can
be changed in the installation of Open-E NAS-XSR).
For security reasons, Open-E NAS-XSR uses the encrypted SSL protocol
(https).
You will now be asked for verification of the encryption certification. Since Open-E
NAS-XSR does not allow for creating shares on the Internet but only on the Intranet,
there is no need for global certification by an authorized body. You can accept the
certificate for the session only, but also for all future use.
Now you have to accept the license in order to use the Open-E software and you can
choose the language you want to use.

13
Page with the software agreement and available language option will be
shown after first launching Open-E NAS-XSR. Later you can change the
language you can change using Language Settings, which are located in
“server” through “setup”.
After accepting License agreement you can log into Open-E NAS-XSR using the
standard password “ancom”(this can be changed later). In order to start working,
you can now set all parameters.
Password checking is case-sensitive. If you cannot log into Open-E NAS-
XSR, please check the status of the Shift and Caps Lock keys.
In case your web browser will show something different then expected,
please delete the cache & cookies in settings menu of your web browser.

14
4.4 Create Disk Array
Use the RAID manager to build a disk array, when a hardware RAID controller is
installed in Open-E NAS-XSR. To create disk arrays utilize 3ware RAID manager (3DM
or 3DM2) in case of RAID controllers series 7000/8000/9000. Use an ICP console for
INTEL/ICP Vortex RAID controllers. For any additional information refer to a RAID
controller user manual.
In case you want use software RAID with single drives or even with installed hardware
RAIDs, please go to menu “RAID|FC” Æ“SW/RAID” first.
You will find the list of available units. A unit can be a single hard disk or disk arrays in
case you have hardware RAID in the system.
Software RAID can be created with single hard disks or hardware disk arrays
accordingly.
To create software RAID, please select units, choose the RAID level and click on
create button.
After clicking “create” button, the status will change to “in use” with additional
information describing the kind of a disk array (e.g. MD0 is RAID 0)
4.5 Adding Disk Array
Please select the “Setup” and then the “Disk Manager”. After selecting the “Disk
Manager” you will find a list of all logical units (i.e. RAID array). To add a new unit to

15
the NAS-XSR, please click “Add” button. After a necessary formatting procedure, the
status of the unit will change from the “Add” button into “In use”.
It is also possible to combine two (or more) units into one Volume Group by choosing
one of actually existing groups like “vg0”, or by choosing “new” option which will
create new group “vg1” after using “add” button.
Please note that you can expand the storage capacity by adding new RAID arrays. In
the “Unit Manager” Open-E NAS-XSR will show both ‘In use’ and new unformatted
units.
Next, with use of function “Logical Volume Manager” you can add disk volume to a
new LV, or increase size of existing LV’s (you can’t decrease LV size). To set needed
LV size just use scrollbar, next to which, on the right side is shown size available to
use. This function can be also used to reserve disk space for “swap” and
“snapshots”. Usually for “snapshots” you need about 10% of new Logical Volume.

16
4.6 Creating NAS-XSR shares
In the menu, please select “Setup,” followed by “server.” Here, you select the type of
authentication. In smaller networks, this should be done via the used workgroup
name, which has to correspond with the workgroup name of the client PC.
In the menu “Resources,” select “Shares” on the right-hand side of the tree diagram.
Now create the first share.
The workgroup/domain name that was configured in Open-E NAS-XSR has
to match with the network settings. Otherwise, the configured shares are not
visible in the network environment.
If you made changes to the workgroup and server name in Open-E NAS-XSR
configuration, it can take some time until each workstation computer in the
Windows network detects the new name.
4.6.1 Access to Windows Shares
The access to newly created shares is generated via the Windows Explorer. After
entering the IP address of your Open-E NAS-XSR (in this example \\192.168.1.2), all
visible shares should be available immediately. Please keep in mind that sometimes
it takes a few minutes for the new shares or changes to become accessible.
When accessing invisible shares, you need to know beforehand the corresponding
share name and attach it to the IP address with a backslash (\):

17
Open-E supports Windows ACL (Access Control List) for read, write and execute
options, but based on the POSIX standard written by SGI.
Some examples how to use ACL (with ADS or PDC authentication):
1. Deny access to a Directory for every user (group):
a. Create a new folder or select one of your existing folders (you must be the owner
or superuser to set ACL permissions)*
b. Go to the “directory properties” (right mouse click on the directory then choose
"Properties")
c. Select a the “security” tab
d. Choose the group "Everyone"
e. Click the "Remove" button – only you and your group will have access to the
selected directory **
f. Click the "Apply" button
Now only you have permissions to access this directory.
2. Allow full access for a group "WORK" to this Directory:
a. Make sure that the group WORK is created
b. In the security window click the "Add" button
c. Click the "Remove" button (point 1)
d. Select the group "WORK" (Advanced ÆFind Now will show you all users and
groups) and click OK
e. Enable Full Control in the “Allow” column
f. Click the "Apply" button
3. Set “read only” permissions to the file for everyone:
a. Create a new file (you must be the owner or superuser to set permissions)*
b. Go to the permissions window
c. Select the “Everyone” group
d. Leave only a ”read” permission in "Allow" column

18
e. Click the "Apply" button
f. Make the same for your group and yourself
Now the group “Everyone” has "read only" permissions to this file.
4. Changing the directory owner:
a. On Open-E web interface go to resources Æshares
b. In the "Set Superuser" function select your user and restart connection
(maintenance Æshutdown ÆFunction Connections reset) or wait about 15
minutes
c. Go to the directory/file properties (right mouse click Æproperties on the directory
and click the "security" tab)
d. Click the "Advanced" button
e. Select the Owner tab
f. Click the "Other Users or Group" button and select the user that will be a new
owner (Advanced ÆFind Now will show all users and groups), click OK***
g. Select the user from the list and click OK and the "Apply" button
h. Click OK and re-open this window to refresh owner.
5. Allow a full access for the user "BIG BOSS" to this Directory
a. Make sure that the "BIG BOSS" exists
b. In the security window click the "Add" button
c. Select the user "BIG BOSS" (Advanced ÆFind Now will show you all users and
groups) and click OK
d. Enable Full Control in the Allow column
e. Click the "Apply" button
6. Allow “read” access for a group "COMPANY" to this directory
a. Make sure that the group "COMPANY" exists
b. In security window click the "Add" button
c. Select the group "COMPANY" (Advanced ÆFind Now will show you all users and
groups) and click OK
d. Enable "Read & Execute" in the Allow column
e. Click the "Apply" button
7. Make “read only” directory with a full access subdirectories for the group “ALL”
(using inheriting permissions)
a. Create a folder "ROOT"
b. Go to the security window
c. Remove both “Everyone” and “Your” group
d. Click the “Advanced” button and then the “Add” button
e. Select the “ALL” group and click OK
f. Change “Apply onto” to “This folder only”
g. In permissions leave only “Traverse Folder / Execute File” and “List Folder / Read
Data”. Click OK
h. Click once again the “Add” button and add ALL group
i. This time select “Apply onto” to “Subfolders and files only” (this step will submit
any inherited permissions)

19
j. Select “Full Control” and OK
k. Click “Apply” to save permissions.
With these settings users from the group “ALL” cannot remove the “ROOT” folder or
make any changes to its contents. All new files/folders will be created based on the
access given by inherited permissions.
Example:
- file /ROOT/some_file.txt can be changed but can not be removed
- directory /ROOT/directory can not be removed but a users from the group ALL can
create folders and files in this directory.
- file /ROOT/directory/my_file.txt can by removed and changed by the group ALL (if
inherited permissions wasn't changed)
8. Inherited permissions
If the file or directory has inherited permissions, all newly created subfolders will
inherit the main folder permissions. All permissions can be changed. Please keep in
mind that changing permissions in the main folder will trigger the same changes to
the inherited permissions of any subfolder within.
