1.2 RAID Concepts
RAID Fundamentals
The basic idea of RAID (Redundant Array of Independent Disks) is to combine multiple
inexpensive disk drives into an array of disk drives to obtain performance, capacity and
reliability that exceeds that of a single large drive. The array of drives appears to the
host computer as a single logical drive.
Five types of array architectures, RAID 1 through RAID 5, were originally defined; each
provides disk fault-tolerance with different compromises in features and performance. In
addition to these five redundant array architectures, it has become popular to refer to a
non-redundant array of disk drives as a RAID 0 arrays.
Disk Striping
Fundamental to RAID technology is striping. This is a method of combining multiple
drives into one logical storage unit. Striping partitions the storage space of each drive
into stripes, which can be as small as one sector (512 bytes) or as large as several
megabytes. These stripes are then interleaved in a rotating sequence, so that the
combined space is composed alternately of stripes from each drive. The specific type of
operating environment determines whether large or small stripes should be used.
Most operating systems today support concurrent disk I/O operations across multiple
drives. However, in order to maximize throughput for the disk subsystem, the I/O load
must be balanced across all the drives so that each drive can be kept busy as much as
possible. In a multiple drive system without striping, the disk I/O load is never perfectly
balanced. Some drives will contain data files that are frequently accessed and some
drives will rarely be accessed.
By striping the drives in the array with stripes large enough so that each record falls
entirely within one stripe, most records can be evenly distributed across all drives. This
keeps all drives in the array busy during heavy load situations. This situation allows all
drives to work concurrently on different I/O operations, and thus maximize the number
of simultaneous I/O operations that can be performed by the array.

NAS System
Definition of RAID Levels
RAID 0 is typically defined as a group of
striped disk drives without parity or data
redundancy. RAID 0 arrays can be configured
with large stripes for multi-user environments
or small stripes for single-user systems that
access long sequential records. RAID 0 arrays
deliver the best data storage efficiency and
performance of any array type. The
disadvantage is that if one drive in a RAID 0
array fails, the entire array fails.
RAID 1, also known as disk mirroring, is
simply a pair of disk drives that store
duplicate data but appear to the computer as
a single drive. Although striping is not used
within a single mirrored drive pair, multiple
RAID 1 arrays can be striped together to
create a single large array consisting of pairs
of mirrored drives. All writes must go to both
drives of a mirrored pair so that the
information on the drives is kept identical.
However, each individual drive can perform
simultaneous, independent read operations.
Mirroring thus doubles the read performance
of a single non-mirrored drive and while the
write performance is unchanged. RAID 1 delivers the best performance of any redundant
array type. In addition, there is less performance degradation during drive failure than in
RAID 5 arrays.
RAID 3 sector-stripes data across groups of
drives, but one drive in the group is dedicated
to storing parity information. RAID 3 relies on
the embedded ECC in each sector for error
detection. In the case of drive failure, data
recovery is accomplished by calculating the
exclusive OR (XOR) of the information
recorded on the remaining drives. Records
typically span all drives, which optimizes the
disk transfer rate. Because each I/O request
accesses every drive in the array, RAID 3
arrays can satisfy only one I/O request at a
time. RAID 3 delivers the best performance
for single-user, single-tasking environments
with long records. Synchronized-spindle drives are required for RAID 3 arrays in order to
avoid performance degradation with short records. RAID 5 arrays with small stripes can
yield similar performance to RAID 3 arrays.
14
User Manual
NAS System
Under RAID 5 parity information is distributed
across all the drives. Since there is no dedicated
parity drive, all drives contain data and read
operations can be overlapped on every drive in the
array. Write operations will typically access one
data drive and one parity drive. However, because
different records store their parity on different
drives, write operations can usually be overlapped.
RAID 6 is similar to RAID 5 in that data protection is achieved by writing parity
information to the physical drives in the array. With RAID 6, however, two sets of parity
data are used. These two sets are different, and each set occupies a capacity equivalent
to that of one of the constituent drives. The main advantage of RAID 6 is High data
availability – any two drives can fail without loss of critical data.
Dual-level RAID achieves a balance between the increased data availability inherent in
RAID 1, RAID 3, or RAID 5, and the increased read performance inherent in disk striping
(RAID 0). These arrays are sometimes referred to as RAID 0+1, RAID 30, or RAID 50.

RAID Management
The subsystem can implement several different levels of RAID technology. RAID levels
supported by the subsystem are shown below.
RAID
Description
Min. Drives
Linear is similar to RAID 0 in that it combines the capacity
of all member drives. The data is written linearly starting
with the first disk drive. When first disk drive becomes
full, the next disk drive is used. There is no data
redundancy.
1
0
Block striping is provided, which yields higher
performance than with individual drives. There is no
redundancy.
2
1
Drives are paired and mirrored. All data is 100%
duplicated on an equivalent drive. Fully redundant.
2
3
Data is striped across several physical drives. Parity
protection is used for data redundancy.
3
5
Data is striped across several physical drives. Parity
protection is used for data redundancy.
3
6
Data is striped across several physical drives. Parity
protection is used for data redundancy. Requires N+2
drives to implement because of two-dimensional parity
scheme.
4
0+1
Combination of RAID levels 0 and 1. This level provides
striping and redundancy through mirroring.
4
30
Combination of RAID levels 0 and 3. This level is best
implemented on two RAID 3 disk arrays with data striped
across both disk arrays.
6
50
RAID 50 provides the features of both RAID 0 and RAID
5. RAID 50 includes both parity and disk striping across
multiple drives. RAID 50 is best implemented on two
RAID 5 disk arrays with data striped across both disk
arrays.

1.3 Disk Drive Organization
The RAID subsystem arranges the disk drives connected to it as a physical drive group
and logical unit (LUN).
1.3.1 Physical Drive Groups
The subsystem has up to a maximum of twelve (12) individual disk drives which can be
used to form a physical drive group. To calculate the total size of a particular drive group,
(Smallest disk size) x (Number of disk) = Capacity for RAID 0
(Smallest disk size) x [(Number of disk) / 2] = Capacity for RAID 1
(Smallest disk size) x [(Number of disk) - 1] = Capacity for RAID 3 or 5
{(Smallest disk size) x [(Number of disks in each sub-array) - 1)]} x (Number of subarrays) = Capacity for RAID 30 or 50
1.3.2 Logical Unit Number (LUN)
A logical unit is a drive group read by the host system as a logical device. The subsystem
supports up to eight (8) LUNs for drive group.
1.3.3 Hot Swap Drive Replacement
The subsystem supports hot-swapping of drives while the system is powered on. A disk
may be disconnected, removed or replaced with a different disk without turning off the
system.
1.3.4 Disk Failure Detection
The subsystem can automatically detect disk failures. It monitors disk activities including

1.4 Array Definition
1.4.1 Array
An Array is a group of physical disks (disk drives) containing one or more Volumes.
When an Array is created, the RAID Level is assigned. RAID Level refers to the level of
data performance and protection of an Array.
It is impossible to have multiple Arrays on the same physical disks. If physical disks of
different capacity are grouped together in an Array, then the capacity of the smallest
disk will become the effective capacity of all the disks in the Array.
1.4.2 Volume
A Volume is seen by the host system as a single logical device. A Volume must be
created on an Array. If there is an existing Array and there is available free raw
capacity, then a new Volume can still be created.
A Volume capacity can consume all or a portion of the capacity available in an
Array. Multiple Volumes can exist on a group of disks in an Array. Additional
Volumes created in an Array will reside on all the physical disks in the Array. Thus
each Volume on the Array will have its data spread evenly across all the disks in
the Array.

9.1 Volume Manager
The Volume Manager is responsible for disk and volume management.
A Volume Group consists of one or more disks that could be individual physical disk(s) or
RAID disk(s), which is/are Volume(s) created using proRAID Manager. The default
proNAS Volume Group (proNASVG) must be created first by joining at least one “New” or
“Non_Initialized” disk to this volume group. The proNASVG holds the NAS system
configuration and the default system Logical Volumes, such as home, public, proBackup
Device, and proBackup Extended Device, as well as user-defined Logical Volumes. Files
and folders reside on these Logical Volumes.
The default proNASVG Volume Group cannot be deleted. When proNASVG is created, the
XFS file system is set in each default Logical Volume. XFS file system is also set in all
user-defined Logical Volumes. XFS is a high performance journaling file system and
provides better recovery time to repair a file system in case of FS damage. The proNAS
Volume Group will dynamically allocate some space from its assigned disks, and
allocation may fail if no more disk space is available. Therefore, make sure to regularly
monitor the available free space of proNAS Volume Group.

9.1.4 Volume Replication
Replication function enables proNAS to replicate a logical volume from one NAS server
(source) to another NAS server (destination). Replication involves intelligent copying and
maintaining of exact copy of a volume from a source server to a destination server. The
destination volume is always an exact copy of the source volume. This is done by
mirroring the whole block device via a standard network interface. This solution creates
a real time replication of data. However, it does not create a cluster solution where you
can have a highly available system.
Note: Logical Volume under snapshot cannot be replicated.
NOTE: Starting with proNAS version 1.1.14, replication of Logical
Volumes with LV capacity up to 3,800,064 MB is now supported.
To enable Replication, select Volume Manager then click Options tab and tick “Enable
Replication function”.

Local - Select the IP address of the local (source) proNAS that will be used for
replication.
Remote - Select or type manually the IP address of remote (destination) proNAS
that will be used for replication.
NOTE: The local and remote IP addresses serve as the channel
between the source and destination NAS servers. This is where the
replication of data takes place. Please be sure to have a good
connection on this medium. As much as possible, set this channel
as a dedicated or a private network. It is recommended to use
different Ethernet port for replication from the Ethernet port used
for data access. It is best to use a crossover network link between
the Ethernet ports involved. Refer to Network Manager Section for
configuring Ethernet port.

Available ports are from 7788 to 77xx.

Connection Type: proNAS supports two types of data replication protocols:
Sync - Synchronous. The system will acknowledge the transaction as completed
after the data is written to the disk of destination proNAS. It is recommended to
use this mode. In most cases, this connection type preserves transaction
semantics. Write IO is reported as completed if it has reached the remote disk.
Async (for high latency network) - Asynchronous. The system will acknowledge
the transaction as completed after the data is written to buffer. It provides faster
transmission and is suitable for busy network. Write IO is reported as completed
if it has reached the local TCP send buffer.
Max Sync Rate – This sets the limit of the bandwidth that will be used by the
synchronization process. Default is 30MB/sec. Minimum value is 4MB/sec and
maximum value is 680 MB/sec – for high latency network environment (e.g. bonding
on Gigabit Ethernet).
Send buffer size (K) - It is the size of the TCP socket send buffer. You can specify
smaller or larger values. Larger values are appropriate for reasonable write
throughput with asynchronous protocol over high latency networks. Default is 512K
and maximum is 1024K.
Time out (sec) - It is the value to wait for connection timeout if the remote node is
degraded. If the remote node fails to send the response packet within the specified
timeout time, the remote node will be considered dead and the TCP/IP connection is
abandoned. The default is 6 sec. Minimum is 1 sec and maximum is 60 sec.
When Lost Connection: When the replication connection is lost, the replication
program can either go stand-alone or will try to reconnect.
Reconnect: The replication program will attempt to reconnect. (Default)
Stand-alone: The replication program will not attempt to reconnect and will go
on stand-alone state. All IO request are only passed locally and no replication.
NOTE: Before replication will be successfully created, a 4GB logical
volume will be created on each node. This will serve as the
metadata device for the replicated volume. This volume is not
mounted and will not be seen on the proNAS GUI. Please be sure
to have an extra 4GB space on either side of your NAS nodes.

5. Initialize the Replication by clicking “Initial Replication” button.
NOTE: After creating a replication, a similar logical volume will be
created on the destination server under the specified VG. At this
point, the replication is not yet initialized and no synchronization.
Replication still needs to be initialized. After selecting “Initial
Replication”, the first node will then connect to the second node
and starts to synchronize. Synchronization typically takes quite a
while especially on larger logical volumes. After initializing, the
source node should be in "Primary" state and the destination node
should be in "Secondary" state. If this is the state, you have now a
working replication. Initializing should be done in the source
volume.
6. The volume replication setting will be initialized.

Secondary: The destination volume. The replicated data on the secondary node is
used for backup only and is not accessible. Only the source data is accessible during
replication.
Unknown: The peer node fails to establish connection.
Setting the replicated volume on destination proNAS to be primary
To set the replicated volume to primary, first you need to set both nodes to
secondary. This can be done by setting the primary to be secondary. After both
nodes becomes secondary/secondary, go to the management GUI of the destination
node. Under the replicated logical volume, press the "Set Primary" button.
WARNING! The replicated volume on the secondary node must not
be mounted. Please do not attempt to mount it manually.
Setting the primary volume to be secondary
To set the primary volume to be secondary, just press the "Set Secondary"
button on the primary node.

To reconnect the replicated volume, press the "Reconnect" button. At some point
if the replication fails to establish connection to the other node, you may try to
set up a connection thru this button. This button will be enabled only if one of the
node losses connection.
Aborting the replication
To abort or drop the replication, press the "Abort Replication" button. To access
the data on the replicated volume after aborting the replication, you may need to

9.4 Share Manager
In proNAS Share Manager, you can create and configure a Share, assign a share owner,
assign user permission, and specify file sharing protocol. Under this node you can also
use duplication function and rsync utility. Duplication is a share function in which you can
replicate your share into another share using file level replication. Rsync utility is used to
copy files either to or from a remote host, or locally on the current host.
In the "Share List" tab, you can list the current shares and also display share information
such as share name, quota, used space, logical volume and share owner. There are 2
Default Share in proNAS: "home" and "public".
Share folder gets created under a logical volume. Make sure that an LV is already
created before creating the share folder or admin can create the share folder and LV
simultaneously, which can be done using the option “Create New Volume” in Properties
tab of Share Manager.

When applying ACL in a share, all the files and subfolders under this share will inherit the
share's permission. "Apply ACL" will propagate the ACL settings of the share folder into
all of its child directories and files. For example, if user1 has read/write permission on
the sub-folder but read only on the share, after applying ACL, user1 will now have a
read-only permission on the sub-folder.

that a Final Cut Pro client can share the same DV media files as an Avid client.
‹ Maximum connection - This option limits the number of simultaneous
connections at a certain time. A value of zero means an unlimited number of
connections will be possible in this share.
NOTE: Only one option from “MediaHarmony AVID” and
“MediaHarmony MXF” can be enabled or selected at a time.
NOTE: In proNAS 1.1.14 and later versions, the default setting of
“Maximum Connections” is 0. If there is a need to limit the number
of simultaneous connections to a share, set it to specific number
instead of 0. In proNAS 1.1.13 and older versions, the default

User Manual
159
NAS System
Here is a short summary of the available options. Please refer to the detailed description
below for a complete description. Some options only have a long variant.
-r, --recursive
recurse into directories
-v, --verbose
increase verbosity. This option increases the amount of information
your are given during the transfer
-l, --links
copy symlinks as symlinks
-p, --perms
preserve permissions. This option causes the receiving Rsync to set
the destination permissions to be the same as the source permissions.
-o, --owner
preserve owner (super-user only). This option causes Rsync to set the
owner of the destination file to be the same as the source file
-g, --group
preserve group. This option causes Rsync to set the group of the
destination file to be the same as the source file.
--ignore-existing
Ignore files that already exist on the receiver. This tells Rsync to skip
updating files that already exist on the destination.
-b, --backup
With this option, preexisting destination files are renamed as each file
is transferred or deleted. You can control where the backup file goes
and what (if any) suffix gets appended using the --backup-dir and -suffix options
--backup-dir=dir
In combination with the --backup option, this tells Rsync to store all
backups in the specified directory. This is very useful for incremental
backups. You can additionally specify a backup suffix using the -suffix option (otherwise the files backed up in the specified directory
will keep their original filenames).
--suffix=SUFFIX
This option allows you to override the default backup suffix used with
the --backup (-b) option. The default suffix is a ~ if no --backup-dir is
specified, otherwise it is an empty string.
-D, --devices
preserve device files
--specials
preserve special files
-t, --times
preserve times
-S, --sparse
handle sparse files efficiently
-z, --compress
Compresses file data during the transfer. This option is useful in slow
links.
-a, --archive
This is equivalent to -rlptgoD. It is a quick way of saying you want
recursion and want to preserve almost everything (with -H being a
notable omission).
-E, --executability This option causes Rsync to preserve the executability (or nonexecutability) of regular files when --perms is not enabled.
-h, --humanreadable
Output numbers in a human-readable format.
--stats
Give some file-transfer stats.
--delete
Delete files that don't exist on the sender.
--log-fileformat=FORMAT
Output filenames using the specified format.
--log-file=FILE
Output filenames using the specified file.
160
User Manual
NAS System
--bwlimit=KB/S
Limit I/O bandwidth; KBytes per second.
-n, --dry-run
This tells Rsync to not do any file transfer; instead it will just report
the actions it would have taken.
--timeout=SECS
Sets the maximum I/O timeout in seconds. If no data is transferred
for the specified time then Rsync will exit. The default is 0, which
means no timeout.
There are lot more useful options that are not included in this list. It may vary depending
on your usage, for more information on Rsync, please visit http://samba.org/rsync/.
After completing the above settings, you can run the Rsync client task immediately by

9.4.6 Duplication
Duplication is a file level snapshot utility for making backups of your local filesystem.
Using Duplication, it is possible to take incremental snapshots of your filesystem at
different points in time. Duplication creates the illusion of having a multiple full backups
by using hard links, while only taking up the space of one full backup plus differences.
This saves much more disk space than one might image. The duplication files will be
directed to a share which you can access via share protocols or by telnet service.
Duplication can be invoked manually or by schedule.
Select the share folder in Share Manager then click “Edit” button.
Creating Duplication by Schedule
To create duplication by schedule, first set the number of total duplication that will be
created, specify which day to be run, set the time task whether by interval or once in a
specific time of day, set the destination path and then click “Save” button. Enable the
schedule by clicking on the "Enable Scheduled" button. To disable the scheduled
duplication, just click on the "Disable Scheduled" button.

The Duplication tab information is shown below.
Execute Day:
Specifies whether the scheduled task is to run on this day.
Execute Time:
Once - Specifies the time of the day the scheduled task create
the snapshot.
Every - Specifies how often the scheduled task is to be repeated.
You can also select the starting time and the ending time.
Destination
Path:
This will be the location where your duplication files will be saved.
The default path will be the path of the share itself. You can
change the path to the other shares except home and public.
Duplication will follow the ACL settings of the destination share. If
you set the destination of your home duplication to a public share
then anybody can access that folders, so please be warned!
Snapshot
Numbers:
Specifies the total number of snapshots that can be created. The
maximum total number of duplication a share can have is 256.
Note: The destination space must be larger than the source.
proNAS will check only the destination volume size, not the share
usage. Be sure that the available space on the destination is
reasonably big enough to accommodate any changes in the source.
Home duplication is a special case. If the destination path of the
home folder is set to the home itself, its duplication files will only
be accessible via NFS or telnet service.

source share must have at least a single file in order for the duplication to work properly.
Removing or Clearing All Duplication Files
To delete all the duplication files of this share on the current destination path, press the
"Delete All" button. Duplication files on the previous destination path will not be removed.
Duplication files of other shares on the same destination path will not also be removed.
Getting the Duplication List
To get the lists of all duplication files of this share on the current destination path, please
press the "Get List" button. The table will then update the lists of duplication folders. The
table includes the date and time it was created and the destination path where it was
saved. Duplication files of this share on the previous destination will no longer be
included in the list. However proNAS will automatically update the duplication list for you
every minute.

User Manual
NAS System
How Duplication Works
After you have created Duplication, your destination path will contain a folder
"._Duplication". (It is hidden by default, to unhide it, uncheck the "hide duplication"
option in the Properties tab of the destination folder). Inside the "._Duplication" folder
are the directories that are created for the various intervals that you have defined. It will
look something like in the figure below.
Inside each of these folders is the full backup of that point in time of the source share.
The format of the duplication folder name will be the share name of the source share
appended by an underscore then the character "Dup" followed by the number of the
interval. "ShareName_Dup.0" will always contain the most recent snapshot and the
duplication with the highest interval number will contain the oldest snapshot. When a
new duplication is run, it will rotate all the duplication directories. The files on oldest
duplication will not be saved and will be replaced with the content of its succeeding
duplication, so please take note of this. The number of duplication will depend on the
number of snapshots that you have defined. You need to increase the total number of
snapshots if you want to save the backups for a longer time. For example, if you set the
snapshot numbers to 60 and you set a schedule to take duplication every day, the very
last backup would be around two months old before it will be discharged if a new
duplication is made.
NOTE: To view the date modified of duplication folders that
corresponds to the date the duplication is taken, use File Manager
and view in detailed mode.

proNAS provides 3 kinds of backup methods:
Incremental: An incremental backup stores all files that have changed
since the last backup. The advantage of an incremental backup is that it
takes the least time to complete. However, during a restore operation,
each incremental backup is processed, which could result in a lengthy
restore job.
Differential: A differential backup contains all files that have changed since
the last FULL backup. The advantage of a differential backup is that it
shortens restore time compared to a full backup or an incremental backup.
However, if you perform the differential backup too many times, the size
of the differential backup might grow to be larger than the baseline full
backup.

Chapter 12 proNAS HA (Optional Function)
12.1 Introduction to proNAS HA
proNAS HA (High Availability) provides solution for business continuity with automatic
failover which ensures that should a critical server become unavailable - due to failure
or maintenance-related downtime — a replica will immediately provide all services in its
place without the need for time-consuming manual procedures.
The core processes of ProNAS HA are implemented as two mutual-guarded fail-safe
proNAS services. They can be manipulated by accessing the Services tab in the proNAS
System Manager node. The dual service architecture of ProNAS HA prevents ProNAS
HA from being the single-point-of-failure of the server cluster.
When a server is down or unavailable, ProNAS HA switches the critical operations of
that server over to the peer server automatically. The switch over procedure can also
be triggered manually to handle scheduled downtime more gracefully and user
transparently. ProNAS HA can be manually instructed to switch over the critical
operations of a server to the peer server. Users can then perform upgrade, replacement,
or maintenance to the hardware and software of that proNAS server. The critical
operations of a server can be configured as auto-switch back. After those critical
operations were taken over by the peer server, ProNAS HA can switch them back to
their original active server when the active server becomes available again. Auto-switch
back ensures that the original load distribution between the two servers will be
resumed immediately when possible.
proNAS HA provides:
Manual or auto-triggered failover to a standby server.
Supports manual or automatic failover back to the original server when ready
Real-time replication minimizes potential data loss
NOTE: Starting with proNAS version 1.1.14, replication of Logical
Volumes with LV capacity up to 3,800,064 MB is now supported in
proNAS HA.

User Manual
NAS System
12.2 Getting Started with proNAS HA
Before Configuring High Availability
Before attempting to configure two proNAS HA as a High Availability pair,
check the following requirements:
1. Each proNAS server box must have a different and unique hostname. (It is
highly recommended to use the same NAS model.)
2. Each proNAS box must have at least two static IP addresses.
3. Must have a reliable heartbeat, private net Ethernet is required, serial
RS232 is optional.
4. ProNAS HA services must be started in both proNAS servers.
5. The maximum number of logical volumes that can be created under HA is
32.
6. ProNAS HA does not support logical volumes larger than 3,800,064 MB.
Users can create and extend volumes larger than 3,800,064 MB but this
cannot be used in proNAS HA.
7. Changing hostname and IP addresses when proNAS HA is running is not
allowed.
8. Snapshot function is disabled under HA.
9. Be sure there are no scheduled snapshot task enabled either on each
proNAS box.
10.ProNAS HA service cannot be started if iSCSI volume exists, Replication is
running, or snapshots exist. Make sure to remove all iSCSI volumes, stop
Replication, or delete snapshots.
Setting up a private network:
Private net is a communication channel between the two proNAS box through which they
exchange information about their states (heartbeats). proNAS supports two private
network, TCP/IP Socket and RS232 Serial Port.
To setup TCP/IP private net: Connect a dedicated network into Ethernet1 adapter. You
may use a crossover cable. Ethernet0 serves as your public net.
To setup RS232 Serial Port private net: Connect a serial cable to either Com1 or Com2
for both proNAS box then configure it under the "Serial Port" tab on System Manager.
NOTE: It is recommended to use both TCP/IP and RS-232 for your
private net. Private net IP will be used for replication and RS-232
for heartbeat.
NOTE: Some proNAS models have eth0 Fast Ethernet port. In order
to have faster access to your proNAS, use the Gigabit Ethernet port
(eth1, if eth0 is Fast Ethernet) as your public net; that is where the
users access your proNAS. Then use eth2 as your Private Net.

12.2.1 Hardware Aspect
Active server: proNAS HA server that performs cluster-protected operations.
Backup (Standby) server: proNAS HA server that can takeover the critical operations
of an active server when the active server is down or unavailable.
Private net: Private net is a dedicated channel for servers to exchange their operating
status (i.e., heartbeat message).
Types of Private Net Available:
TCP/IP socket: Ethernet network running TCP/IP protocol. Each server must
install a dedicated IP to attach to the private net.
RS-232 serial port: One free serial port per server. A null modem cable must be
installed to connect the serial ports of the two servers.
Public net: Public net is the paths for networked clients to access cluster- protected
resources.

12.2.2 Procedure for Setting Up proNAS HA
Setting up a server cluster:
Below are the basic steps in setting up a server cluster:
1.
2.
3.
4.
Configure the hostname for both proNAS servers (must be unique).
Configure two static IP addresses for each proNAS server.
Set up private net. At least the private net IP must be configured to start cluster.
Start proNAS HA service for both proNAS servers. You may do this under System
Manager then Services tab, highlight proNAS HA service then click Start. proNAS
HA node will then appear on the left tree after it starts successfully.
5. On the designated Active Server, go to proNAS HA->"General Settings".
6. On the "General Setting" tab, click "Edit" button. Input the Peer Server hostname
then select "Active (local-host) – Standby (peer host) Mode" under the
Cluster mode. Click "Save".
NOTE: The Cluster Mode of Backup Server must be configured as
“Standby(local host) – Active(peer-host) Mode” (see Step 10).
Other configuration options:
Computer Name:
Local Server: The hostname of the Active or Primary server
Peer Server: The hostname of the Backup or Secondary server

Reference IP:
Enable Reference IP Checking – Select this option to enable reference
IP checking. A Reference IP is an IP that the proNAS HA
service will check when the heartbeat channel(s) between
the two servers are lost. The IP of a router or any network
device which is always online can be used as a Reference IP.
IP Address – Enter the IP address of the Reference IP to check the
availability of the servers.
Event Log:
Level – Select the type of logging that will be used for proNAS HA service.
Default is Normal which shows operation processes. Other
option is Trace, which shows operation and traceable
processes.
Preserved Days – Select the number of days that the log will be
preserved before deleting.
Operational Preferences:
On Server Shutdown, failover the resource groups automatically –
When enabled, the resource groups will be failed over to the
other server when this server shutdown.
On Server Startup, start the cluster system automatically – When
enabled, the cluster system will be started automatically
when this server starts up.
