sales or email to “sales@thecus.com”.
i Series connects to the host system in iSCSI interface. It can be configured to
any RAID level. i Series provides reliable data protection for servers and the
RAID 6 function ready. The RAID 6 function allows two HDD failures without any
impact on the existing data. Data can be recovered from the remaining data and
parity drives. (Data can be recovered from the rest disks/drives.)
Thecus RAID system is the most cost-effective disk array system with
completely integrated high-performance and data-protection capabilities which
meet or exceed the highest industry standards, and the best data solution for
small/medium business (SMB) users.
Caution
Please refer to RAM certification list in Appendix A for more
detail.

1.2 Terminology
The document uses the following terms:
RAID
PD
VG
UDV
CV
RAID is the abbreviation of “Redundant Array of Independent
Disks”. There are different RAID levels with different degree
of the data protection, data availability, performance to host
environment.
The Physical Disk belongs to the member disk of one specific
volume group.
Volume Group. A collection of removable media. One VG
consists of a set of UDVs and owns one RAID level attribute.
User Data Volume. Each VG could be divided into several
UDVs. The UDVs from one VG share the same RAID level,
but may have different volume capacity.
Cache Volume. i Series uses the on board memory as cache.
All RAM (except for the part which is occupied by the
controller) can be used as cache. User can divide the cache
for one UDV or sharing among all UDVs. Each UDV will be
associated with one CV for data transaction. Each CV could
be assigned different cache memory size.
LUN
GUI
RAID width,
RAID copy,
RAID row
(RAID cell in
one row)
Logical Unit Number. A logical unit number (LUN) is an
unique identifier used on a iSCSI connection which enables it
to differentiate among separate devices (each of which is a
logical unit).
Graphic User Interface.
RAID width, copy and row are used to describe one VG.
E.g.:
1. One 4-disk RAID 0 volume: RAID width= 4; RAID copy=1; RAID row=1.
2. One 3-way mirroring volume: RAID width=1; RAID copy=3; RAID row=1.
3. One RAID 10 volume over 3 4-disk RAID 1 volume: RAID width=1; RAID copy=4; RAID row=3.
- 6 -
WT
WB
RO
DS
GS
Write-Through cache write policy. A caching technique in
which the completion of a write request is not signaled until
data is safely stored on non-volatile media. Each data is
synchronized in both data cache and the accessed physical
disks.
Write-Back cache write policy. A caching technique in which
the completion of a write request is signaled as soon as the
data is in cache and actual writing to non-volatile media
occurs at a later time. It speeds up system write performance
but needs to bear the risk where data may be inconsistent
between data cache and the physical disks in one short time
interval.
Set the volume to be Read-Only.
Dedicated Spare disks. The spare disks are only used by one
specific VG. Others could not use these dedicated spare disks
for any rebuilding purpose.
Global Spare disks. GS is shared for rebuilding purpose. If
some VGs need to use the global spare disks for rebuilding,
they could get the spare disks out from the common spare
disks pool for such requirement.

Chapter 2 Getting started
2.1 Before starting
Before starting, prepare the following items.
1. Check the “Certification list” in Appendix A to confirm the hardware
setting is fully supported.
2. Read the latest release notes before upgrading. Release notes accompany with release firmware.
3. A server with a NIC or iSCSI HBA.
4. CAT 5e, or CAT 6 network cables for management port and iSCSI data ports. Recommend CAT 6 cables for best performance.
5. Prepare storage system configuration plan.
6. Management and iSCSI data ports network information. When using static IP, please prepare static IP addresses, subnet mask, and default gateway.
7. CHAP security information, including CHAP usernames and secrets. (Optional)
2.2 iSCSI introduction
iSCSI (Internet SCSI) is a protocol which encapsulates SCSI (Small Computer
System Interface) commands and data in TCP/IP packets for linking storage
devices with servers over common IP infrastructures. iSCSI provides high
performance SANs over standard IP networks like LAN, WAN or the Internet.
IP SANs are true SANs (Storage Area Networks) which allow few of servers to
attach to an infinite number of storage volumes by using iSCSI over TCP/IP
networks. IP SANs can scale the storage capacity with any type and brand of
storage system. In addition, using any type of network (Ethernet, Fast Ethernet,
Gigabit Ethernet) and combining operating systems (Microsoft Windows, Linux,
Solaris, …etc.) within the SAN network. IP-SANs also include mechanisms for
security, data replication, multi-path and high availability.
Storage protocol, such as iSCSI, has “two ends” in the connection. These ends
are the initiator and the target. In iSCSI we call them iSCSI initiator and iSCSI
target. The iSCSI initiator requests or initiates any iSCSI communication. It
requests all SCSI operations like read or write. An initiator is usually located on
the host/server side (either an iSCSI HBA or iSCSI SW initiator).
- 9 -
The iSCSI target is the storage device itself or an appliance which controls and
serves volumes or virtual volumes. The target is the device which performs SCSI
commands or bridges it to an attached storage device. iSCSI targets can be
disks, tapes, RAID arrays, tape libraries, and etc.

Figure 2.2.1
The host side needs an iSCSI initiator. The initiator is a driver which handles the
SCSI traffic over iSCSI. The initiator can be software or hardware (HBA). Please
refer to the certification list of iSCSI HBA(s) in Appendix A. OS native initiators or
other software initiators use the standard TCP/IP stack and Ethernet hardware,
while iSCSI HBA(s) use their own iSCSI and TCP/IP stacks on board.
Hardware iSCSI HBA(s) would provide its initiator tool. Please refer to the
vendors’ HBA user manual. Microsoft, Linux and Mac provide software iSCSI
initiator driver. Below are the available links:
1. Link to download the Microsoft iSCSI software initiator:
http://www.microsoft.com/downloads/details.aspx?FamilyID=12cb3c1a15d6-4585-b385-befd1319f825&DisplayLang=en
Please refer to Appendix C for Microsoft iSCSI initiator installation procedure.
2. Linux iSCSI initiator is also available. For different kernels, there are
different iSCSI drivers. Please check Appendix A for software iSCSI
initiator certification list. If user needs the latest Linux iSCSI initiator,
please visit Open-iSCSI project for most update information. LinuxiSCSI (sfnet) and Open-iSCSI projects merged in April 11, 2005.

3.2 Login
i Series supports graphic user interface (GUI) to operate the system. Be sure to
connect the LAN cable. The default IP address is 192.168.1.100; open the
browser and enter:
http://192.168.1.100 (Please check IP address first on LCM)
Click any function at the first time; it will pop up a dialog for authentication.
Login name: admin
Default password: admin
After login, you can choose the function blocks on the left side of window to do configuration.
Figure 3.2.1
There are four indicators at the top-right corner.
Figure 3.2.2
- 16 -
1. RAID light: Green means RAID works well. Red represents RAID
failure happening.
2.
3.
4. UPS light: Green is normal. Red represents abnormal UPS status.
Temperature light: Green is normal. Red represents abnormal
temperature.
Voltage light: Green is normal. Red represents abnormal voltage
status.
3.3 Quick install
It is easy to use “Quick install” function to create a volume. Depend on how
many physical disks or how many residual spaces on created VGs are free, the
system will calculate maximum spaces on RAID levels 0/1/3/5/6. “Quick install”
function will occupy all residual VG space for one UDV.
Quick Install function has a smarter policy. When the system is full inserted with
5 HDD, and all HDD are in the same size, Quick Install function lists all
possibilities and sizes among different RAID levels, Quick Install will use all
available HDD for the RAID level which user decides. But, when the system is
inserted with different sizes of HDD, e.g., 2*200G HDD and 3*80G, i Series also
lists all possibilities and combinations of different RAID Level and different sizes.
After user chooses RAID level, user may finds there are still some HDD are not
used (Free Status). The result is from i Series’s smarter policy on Quick Install
which gives user:
1. Biggest capacity of RAID level which user chooses and,
2. The fewest disk number for the RAID level/volume size.
- 17 -
Step 1: Select “Quick install” then choose the RAID level to set. Please refer to
Figure 3.3.1. After choosing the RAID level, click “ ”, which
links to another page, user can set up “LUN” here.
Figure 3.3.1
Step 2: Please select a LUN number. Access control of host would show as a
wildcard “*”, which means every host can access this volume. In this page, the
“Volume size” can be changed. The maximum volume size is shown. To re-enter
the size be sure it has to be less or equal to maximum volume size. Then click
“ ”.
Step 3: Confirm page. Click “ ” if all setups are correct. Then
a page with the “User data volume” just been created will be shown as Figure
3.3.2.
Done. You can start to use the system now.

For customizing your own display of event logs, there are total three display
methods, on Web UI/Console event log page, popup windows on Web UI, and on
LCM. The default setting of these three displays is WARNING and ERROR event
logs enabled on Web UI and LCM. The popup is default disabled.
Figure 3.4.11.2
The event log is displayed in reverse order which means the latest event log is on
the first page. The event logs are actually saved in the first four hard drives; each
hard drive has one copy of event log. For one controller, there are four copies of
event logs to guarantee users can check event log most of the time when there
is/are failed disk(s).
Tips
Please plug-in anyone of first four hard drives, and then event
logs can be saved and appeared in next system boot up.
Otherwise, event logs would be gone.
