iStarUSA’s iSCSI solution is the most cost-effective disk array controller 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.

1.2 Terminology

The document uses the following terms:

RAID

RAID is the abbreviation of “Redundant Array of Independent
Disks”. There are different RAID levels with different degree
of the data protection, data availability, and performance to
host environment.

PD

The Physical Disk belongs to the member disk of one specific
volume group.

VG

Volume Group. A collection of removable media. One VG

consists of a set of UDVs and owns one RAID level attribute.

UDV

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.

CV

Cache Volume. Controller uses onboard memory as cache.

All RAM (except for the part which is occupied by the
controller) can be used as cache.

LUN

Logical Unit Number. A logical unit number (LUN) is a unique

identifier which enables it to differentiate among separate
devices (each one is a logical unit).

GUI

Graphic User Interface.

RAID width,
RAID copy,

RAID width, copy and row are used to describe one VG.
E.g.:

- 9 -

RAID row
(RAID cell in
one row)

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.

WT

Write-Through cache-write policy. A caching technique in

which the completion of a write request is not signaled until
data is safely stored in non-volatile media. Each data is
synchronized in both data cache and accessed physical
disks.

WB

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.

RO

Set the volume to be Read-Only.

DS

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.

GS

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.

DC

Dedicated Cache.

GC

Global Cache.

DG

DeGraded mode. Not all of the array’s member disks are

functioning, but the array is able to respond to application

- 10 -

read and write requests to its virtual disks.

SCSI

Small Computer Systems Interface.

iSCSI

Internet Small Computer Systems Interface.

S.M.A.R.T.

Self-Monitoring Analysis and Reporting Technology.

WWN

World Wide Name.

HBA

Host Bus Adapter.

SAF-TE

NIC

Network Interface Card.

LACP

Link Aggregation Control Protocol.

MPIO

Multi-Path Input/Output.

MC/S

Multiple Connections per Session

MTU

Maximum Transmission Unit.

CHAP

Challenge Handshake Authentication Protocol. An optional

security mechanism to control access to an iSCSI storage
system over the iSCSI data ports.

iSNS

Internet Storage Name Service.

1.3 RAID levels

1.4 Volume relationship diagram

Figure 1.4.1

This is the volume structure of Netstor designed. It describes the relationship
of RAID components. One VG (Volume Group) consists of a set of UDVs
(User Data Volume) and owns one RAID level attribute. Each VG can be
divided into several UDVs. The UDVs in one VG share the same RAID level,
but may have different volume capacity. Each UDV will be associated with
one specific CV (Cache Volume) to execute the data transaction. Each CV
can have different cache memory size by user’s modification/setting. LUN
(Logical Unit Number) is a unique identifier, in which users can access
through SCSI commands.

Chapter 2 Getting started

2.1 Before starting

Before starting, prepare the following items.

1. Check “Certification list” in Appendix A to confirm the hardware
setting is fully supported.

2. Read the latest release note before upgrading. Release note
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. Gigabit LAN switches. (recommended) Or Gigabit LAN switches
with VLAN/LCAP/Trunking functions. (optional)

8. CHAP security information, including CHAP username and
password. (optional)

9. Setup the hardware connection before power on servers and
Netstor iSCSI storage. Connect console cable, management port
cable, and iSCSI data port cables in advance.

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(Storage Area Networks) allow few servers to attach to an infinite

- 14 -

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, it can be used by any type of network (Ethernet, Fast Ethernet, and
Gigabit Ethernet) and combination of 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 initiator and 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).

The target is the storage device itself or an appliance which controls and
serves volumes or virtual volumes. The target is the device which executes
SCSI commands or plays a role as the bridge to an attached storage device.

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 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) provide its own initiator tool. Please refer to the
vendors’ HBA user manual. Microsoft, Linux and Mac provide iSCSI initiator
driver. Below are the available links:

1. Link to download the Microsoft iSCSI software initiator:

Please refer to Appendix D 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 iSCSI initiator
certification list. If user needs the latest Linux iSCSI initiator, please
visit Open-iSCSI project for most update information. Linux-iSCSI
(sfnet) and Open-iSCSI projects merged in April 11, 2005.

2.3 Management methods

There are three management methods to manage iStarUSA iSCSI storage,
described in the following:

- 16 -

2.3.1 Web GUI

iStarUSA iSCSI storage support graphic user interface(GUI) to manage the

system. Be sure to connect LAN cable. The default setting of management
port IP is DHCP and DHCP address displays on LCM; user can inspect LCM
for IP first, then open the browser and type the DHCP address: (The DHCP
address is dynamic and user may need to check every time after reboot.)
When DHCP service is not available, controllers use zero configuration
(Zeroconf) to get an IP address.

Take an example on LCM:

192.168.1.1
GbE iSCSI Storage

http://192.168.1.1

Click any function at the first time; it will pop up a dialog to authenticate
current user.

Login name: admin
Default password: 1234

Or login with read-only account which only allows to read the configuration but
cannot change setting.

Login name: user
Default password: 1234

2.3.2 Remote control – secure shell

SSH (secure shell) is required for administrators to login from a remote
location. The SSH client software is available at the following web site:
SSHWinClient WWW: http://www.ssh.com/
Putty WWW: http://www.chiark.greenend.org.uk/

Host name: 192.168.1.1 (Please check your DHCP address for this field.)

2.4.2 System buzzer

The system buzzer features are listed below:

1. The system buzzer alarms 1 second when system boots up
successfully.

2. The system buzzer alarms continuously when there is an error
occurred. The alarm will be stopped after the error is cleared or the
alarm is muted.

3. The alarm will be muted automatically when the error is cleared.
E.g., when RAID 5 is degraded then the alarm rings immediately,
user changes/adds one physical disk for rebuilding. When the
rebuilding is done, the alarm will be muted automatically.

2.4.3 LED

The LED features are listed below:

1. Marquee / Disk Status / Disk Rebuilding LED: The Marquee /
Disk Status / Disk Rebuilding LEDs are displayed with same LEDs.
The LEDs indicates different functions in different stages.

I. Marquee LEDs: When the system successfully boots up, the

Marquee LED is on until the system boots successfully.

II. Disk status LEDs: the LEDs reflect the disk status for the tray.

Only On/Off situation.

III. Disk rebuilding LEDs: the LEDs are blinking when the disks

are under rebuilding.

2. Disk Access LED: Hardware activated LED

when accessing disks

(IO).

3. Disk Power LED: Hardware activated LED when the disks are
plugged in and powered on.

4. System status LED: Used to reflect the system status, when turned

iStarUSA iSCSI storage supports graphic user interface (GUI) to operate the

system. Be sure to connect the LAN cable. The default IP setting is DHCP;
open the browser and enter:

http://192.168.xx.xx (Please check the DHCP address first on LCM.)

Click any function at the first time; it will pop up a dialog for authentication.

Login name: admin
Default password: 1234

After login, you can choose the functions which lists on the left side of window
to setup configuration.

- 24 -

Figure 3.2.1

There are four indicators at the top-right corner.

Figure 3.2.2

1.

RAID light: Green means RAID works well. Red represents

RAID failure.

2. Temperature light: Green means normal temperature. Red
represents abnormal temperature.

3.

Voltage light: Green means normal voltage. Red represents

abnormal voltage..

4.

UPS light: Green means UPS works well. Red represents UPS

failure.

3.3 Quick install

It is easy to use “Quick install” to create a volume. Depends on how many
physical disks or how many residual spaces are free, the system will calculate

- 25 -

maximum spaces on RAID levels 0/1/3/5/6/0+1. “Quick install” will occupy all
residual VG space for one UDV.

“Quick Install” has a smarter policy. When the system is inserted with some
HDDs. “Quick Install” lists all possibilities and sizes in different RAID levels, it
will use all available HDD for RAID level depends on user’s choose. When
system has different sizes of HDDs, e.g., 8*200G and 8*80G, it lists all
possibilities and combinations in different RAID levels and different sizes.
After user sets the RAID level, user may find there are still some HDDs are
available (free status). The result is using smarter policy designed by iStarUSA.
It gives user:

1. Biggest capacity of RAID level for user to choose.

2. The fewest disk number for RAID level / volume size.

E.g., user chooses RAID 5 and the iStarUSA iSCSI Storage has 12*200G +
4*80G HDDs inserted. If we use all 16 HDDs for a RAID 5, and then the
maximum size of volume is 1200G (80G*15). With the wizard, we can do

smarter check and find out

the most efficient way of using HDDs. The wizard
only uses 200G HDDs (Volume size is 200G*11=2200G), the volume size is
bigger and fully uses HDD capacity.

Step 1: Select “Quick install” and then choose the RAID level. After RAID
level is chosen, click “ ”. Then it will link to next page.

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 to this volume. In this page,

- 26 -

the “Volume size” can be changed. Default value is the maximum volume
size. To adjust the size, notice that it is less or equal to maximum volume size.
Then click “ ”.

Step 3: Confirm page. Click “ ” if all configurations are
correct. Then a UDV will be created.

Done. You can start to use the system now.

Figure 3.3.2

(Figure 3.3.2: A RAID 0 user data volume with the UDV name “QUICK68809”, named by
system itself, with the total available volume size 609GB.)

3.4 System configuration

“System config” is designed for setting up the “System name”, “IP
address”, “Language”, “Login config”, “Password”, “Date”, “Mail”,
“SNMP”, “Messenger”, “System log server” and view “Event log”.
