[Limitations]
1. There is a capacity limit for different file systems. It means, if more than six 3 TB HDD
installed, you may have select suitable file system when creating a RAID volume.
File System
Capacity Limit
EXT3
16 TB
EXT4
> 16 TB
XFS
> 16 TB
2. N12000/N16000 support up to five RAID volumes. For HA RAID volume, just one is
allowed.
V1.4.2

OS5 X64 FW 2.05.08
3. RAID volume encryption : AES 256 bits
a. NAS admin has to insert an USB flash disk to save encryption key file on it.
b. To encrypt an existing RAID is not possible. Please do it while creating a new
RAID.
c. NAS performance will drop significantly while using encrypted RAID.
d. The USB flash disk (key file) should exist whenever the NAS reboots/boots up
and doing RAID configuring.
e. Encrypted RAID doesn’t support on-line Expansion, just off-line Expansion is
doable.
f. Encrypted RAID support file system check since V2.03.05.
g. If the USB flash disk (key file) lost or key file modified, the RAID data will
be INACCESSIBLE FOREVER and no way to recover it.
4. Once the RAID created, there will be about 5% data used by EXT3/EXT4 file system. The
capacity stores the journal and inodes; which are necessary to keep RAID data safer.
5. RAID rebuild : in case one HDD failed in RAID 1, 5, 6, 10, 50, and 60 configurations,
please hot unplug failed one and hot plug in new one; then RAID rebuilding will
automatically start. If the replacement is done after NAS shutdown, administrator has to
manually add spare in Admin Web GUI to start the RAID rebuilding.
6. RAID Expansion: When changing the RAID 5 configuration from five smaller disks to five
bigger disks, you have to change one disk at a time and then rebuild the RAID. Lastly,
utilize the newly added capacity from Space Allocation page.
7. iSCSI Target : the maximum numbers of iSCSI target volumes depend on the physical
memory size and also the CPU power of each Thecus NAS. No matter one RAID or
multiple RAID volumes exist in a NAS, the maximum limit will be the same.
Max. No of iSCSI Targets

N8900/N16000
a. For NAS admin without cluster based OS/applications to manage multiple
initiators connected to the same iSCSI volume, we highly recommend every
iSCSI volume is connected by single iSCSI initiator. However, in case NAS
admin has cluster based OS/applications, up to 8 initiators is possible.
b. Uncontrolled concurrent access to the same iSCSI target volume may result
data corruption or un-predicable results.
c. iSCSI target may be disconnected from initiator if other RAID settings on the
same target NAS being altered.
d. Verified iSCSI initiators:
Windows: Microsoft initiator v2.0.4
V1.4.2
3/9
Apr/07/2015
OS5 X64 FW 2.05.08
StarPort initiator 3.5.2
MAC OS: globalSAN iSCSI initiator version 4.1 (279)
Linux: open-iscsi 2.0-865
e. There is a system advanced option to choose 4K or 512 bytes block size for
iSCSI volume, and the default is 4K bytes. 512 bytes block size may encounter
2TB volume capacity limitation on some initiators running 32bit OS.
Nevertheless, 4K block size could slice the iSCSI volume over 2TB, but, there
might be compatibility issue. For VMware, we recommend using 512 bytes
block size.
8. iSCSI Expansion : there are some limitations applied.
a. The maximum iSCSI volume would be 16TB (EXT3/EXT4), and the minimum
expansion size is 1GB.
b. There is no iSCSI volume size limitation with XFS RAID volume.
c. iSCSI service will be stopped till the expansion completes.
d. iSCSI expansion just handles the volume size. The partition(s) inside the volume
won’t be adjusted.
e. iSCSI expansion just support local RAID, does not support add-on RAID by
iSCSI stackable.
9. Stackable function : Support of stackable function across Thecus N8900/N12000/N16000
NASes.
a. The concurrent connection on target iSCSI volume of Thecus NAS will be limited
to 1 if the initiator comes from other Thecus NASes.
b. The internal file system format of stackable target is EXT4, and the maximum
capacity is 16 TB.
10. iSCSI Thin-Provisioning
a. The Thin-Provision capacity has to be determined first.
b. Up to five iSCSI Thin-Provision target can be created on the Thin-Provision
capacity.
c. The total virtual size of iSCSI Thin-Provision targets in a RAID:
Thin-Provisioning
File System
Capacity Limit
EXT3
16 TB
EXT4
16 TB
XFS
64 TB
d. The virtual size should be larger than the real capacity and less than 16 TB.
e. When determine the virtual size, the minimum increase is 100GB.
f. When the total used capacity reaches 90% of real Thin-Provision capacity, NAS
will send E-mail notifications out every 10 minutes until the capacity expanded.
Also, system log will show capacity warning in admin web interface. The host
server won’t receive any notification before the iSCSI Thin-Provision target full.
V1.4.2

11. iSCSI LUN ID in admin web interface
a. The iSCSI LUN ID is between 0 and 254.
b. Duplicate ID is not allowed excepting ID 0.
c. Mac computer just recognized the first iSCSI volume.
12. Active Directory Support behavior : before AD Sync is pressed, search criteria has to be
a fully match string to user account. After AD Sync is pressed, search criteria can be
only beginning part of the user account. Only 1000 search results will be displayed.
13. To enable ADS support for Small Business Server 2003, we recommend do not install
ISA server. Otherwise, N8900/N12000/N16000 series may fail to join the AD.
14. User Quota : user quota has been added since firmware version 1.00.01.
a. Value "0" means "User Quota Disabled"
b. A quota setting will be applied across multiple RAID volumes. It means, if you set
10GB quota for user John, he will be having 10GB on every RAID. For a NAS
with three RAID volumes, John will have 30GB quota in total.
c. "User Quota" is implemented in EXT3, EXT4, and XFS RAID.
d. When using "User Quota" in a Master and XFS RAID, disabling quota might not
take effective until the NAS reboots.
e. When "User Quota" full, the user will have 10% tolerance within 7 days; thus he
can do some data moving and deleting temporarily.
f. System log and Email Notification will remind the users whose "User Quota"
reached the limit at 24:00 everyday.
g. The status of "User Quota" across multiple RAID will be displayed on [User and
Group Authentication > Quota > Quota Setting] page.
h. It may take long time to enable the "User Quota" the 1st time.
i. "User Quota" is calculated by UID in the NAS.
j. When users put data into a public folder, the used capacity will not be added to
quota calculation. Also, data copied through WebDisk will not be calculated
either.
15. Some attributes may not be included with files and folders when copying to a USB drive
with FAT32 format.
16. If a USB hard drive is connected to NAS formatted as FAT16/32, the following
restrictions apply:
- Copy file with size greater than or equal to 2 GB to the NAS can not be performed
due to FAT file system limitation.
- Files created by Mac OS X like DS_Store can not be copied to the FAT16/32 USB
drive.
17. NFS share is limited to public folders. In case you enable an NFS share on non-public
(ACL) folder, the NFS client could successfully mount it but won’t be able to read/write
files. Currently we implemented NFS V3 & V4.

18. Reset button : In case the admin password or HTTP port lost, use Reset botton to load
factory default please. In that case, user accounts and groups will be erased, but RAID
data won’t be affected.
19. HTTP and HTTPS ports should follow the rules given below.
- Larger than 1024
- Could not use 3169
- Port 80 (HTTP) and 443 (HTTPS) are allowed
20. Mac OS Limitations
a. When using Mac OS X (post 10.2 with AppleTalk) without SMB, do not use
Japanese characters in folder or file names to prevent errors accessing the data
over a network.
b. Mac OS 9 and Mac OS X can not see files on the network with names made up
of over 32 characters.
c. Mac OS 8.x/9.x only supports local character encoding on file names (without
Unicode support).
d. Occasionally, when a file is accessed by a Mac OS computer within a shared
folder, an information file will be created in the same folder. If the file is then
deleted by a Windows OS computer, the original file may no longer be
accessible by Mac OS computers.
e. The following characters are not allowed to be included in the name used for a
file or shared folder when using Mac OS (AppleTalk) devices.
?[]/\=+<>;:”,|*
f. Writing a file larger than 2 GB is not allowed by MAC OS-9.
21. NAS needs about 5 minutes to broadcast/register itself to other Mac OS through
AppleTalk after booting up and service enabled.
22. WebDisk : Only UTF-8 file name is supported.
23. File size has to be less than 1GB to be uploaded to Thecus NAS from web browsers.
FTP software has no such limitation.
24. File names and folder names should not contain more than 250 characters in their entire
directory path to prevent errors occur in the file copy operations.
25. The following characters are not allowed to be included in the name used for files or
folders on Thecus NAS.
/\:*?”<>|[]=+;,
26. File and directory attributes can not be modified by an FTP client when the FTP server
of Thecus NAS is enabled.
27. Anonymous FTP user could upload files into public folders but could not delete them.
28. FTP client can list up to 2000 files in a single folder.
29. Thecus NAS could work as a TFTP server since firmware 1.00.01.
a. TFTP service folder should be public and without any ACL rule.
b. Double byte file name (Chinese, Japanese, Korean, etc) may have problems in
V1.4.2
6/9
Apr/07/2015
OS5 X64 FW 2.05.08
case the TFTP client doesn't support UTF8. Anyway we recommend using
single byte characters as the file name.
c. TFTP service runs at port 69 by default. It is changeable from admin web
interface. Please notify possible port conflicts, if any.
d. The biggest file size is 4GB while transferring thru TFTP.
30. N8900/N12000/N16000 support specific 10 GbE NIC cards. There will be Additional
LAN 1, 2, 3, and 4 to configure the network setting in admin web interface. However, the
Link Aggregation functions will just work on original two on-board NIC, WAN/LAN1 and
LAN2.
31. File system check page is in English, no multilingual.
32. Disk Power Management : some HDD may not respond to “idle spin down” command,
and they won’t get into stand by mode even if the specified idle time had been reached.
In addition, N8900/N12000/N16000 do not support SAS HDD spin down at current
moment.

[Known Problems]
1. Using samba protocol in MAC OS will not accept file names with blank characters in tail.
2. IE7 / IE8 will show certification error alert while user access WEB admin UI via HTTPS.
[Attention]
1. During firmware upgrade process, it is imperative that user DO NOT turn off the
power to Thecus NAS or closes the browser window. This will lead to catastrophic
result. If your browser is set to cache the screen, after firmware upgrade has
started for 5 minutes, please press CTRL-F5 to reload browser screen from server
instead of from browser cache.
2. Thecus strongly recommends NAS admin to backup the RAID data before doing
the RAID Migration and Expansion. There is potential risk of permanent data loss
when doing Migration/Expansion with disk drives having physical problems, and
Thecus is not responsible for any data loss and recovery expense.
3. Enforce to enable the system beeper notification after firmware updated.

4. When installing the Windows Wizard program of Thecus NAS on Windows XP
Professional SP1 or SP2, Windows Vista, and newer OS, the firewall UDP ports 10000
and 10001 need to be opened.
5. Reset to factory default function automatically resets all the system settings including
network settings, administrator password, user groups, language setting, system
notification setting, and time zone setting.
6. Users should obey the international RF regulatory rules as they set up the wireless RF
channel on the NAS. The RF operating channels for different regions have been
specified as following. Thecus has no responsibility for users attempting to violate the
international RF regulation.
