IS16GL connects to the host system in iSCSI interface. It can be configured to any RAID level. IS16GL 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.)

Snapshot-on-the-box is a fully usable copy of a defined collection of data that contains an image of the data as it appeared at the point in time, which means a point-in-time data replication. It provides consistent and instant copies of data volumes without any system downtime. IS16GL Snapshot-on-the-box can keep up to 32 snapshots for all data volumes. Rollback feature is provided for restoring the previously-snapshot data easily while continuously using the volume for further data access. The data access is regular as usual including read/write without any impact to end users. The "on-the-box" terminology implies that it does not require any proprietary agents installed at host side. The snapshot is taken at target side and done by IS16GL. It will not consume any host CPU time thus the server is dedicated to the specific or other application. The snapshot copies can be taken manually or by schedule every hour or every day, depends on the modification.

IS16GL is the most cost-effective disk array subsystem with completely integrated high-performance and data-protection capabilities which meet or

exceed the highest industry standards, and the best data solution for

Caution

small/medium business users.

Snapshot/rollback features need 512MB RAM or more. Please refer to RAM certification list in Appendix A for more detail.

1.2 Terminology

The document uses the following terms:

RAID

VG Volume Group. A collection of removable media. One VG

UDV

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.

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. IS16GL 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 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).

GUI Graphic User Interface.

- 6 -

RAID width, RAID copy, RAID row

(RAID cell in one row)

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.

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 on non-volatile media. Each data is synchronized in both data cache and the 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.

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 read and write requests to its virtual disks.

2.7 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).

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.

HBA

- 17 -

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=12cb3c1a-15d64585-b385-befd1319f825&DisplayLang=en

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 software iSCSI initiator certification list and “OS_HBA_Initiator List.pdf” for latest update and detail information. If you need 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.

2.8 Management methods

There are three management methods to manage IS16GL, describe in the following:

2.8.1 Web GUI

IS16GL support graphic user interface to manage the system. Be sure to connect LAN cable. The default setting of management port IP is DHCP and the DHCP address displays on LCM; user can check LCM for the IP first, then open the

- 18 -

browser and type the DHCP address: (The DHCP address is dynamic and user may need to check every time after reboot again.) When DHCP service is not available, IS16GL use zero config (Zeroconf) to get an IP address.

E.g., on LCM. IS16GL gets a DHCP address 192.168.10.50 from DHCP server.

192.168.10.50

IS16GL ←

http://192.168.10.50

https://192.168.10.50 (https: connection with encrypted Secure Sockets

Layer (SSL). Please be aware of the https function is slower than http.)

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

Or login with the read-only account which only allows seeing the configuration and cannot change setting.

2.8.2 Console serial port

Use NULL modem cable to connect console port. The console setting is baud rate: 115200, 8 bits, 1 stop bit, and no parity. Terminal type: vt100 Login name: admin Default password: 00000000

2.8.3 Remote control – secure shell

SSH (secure shell) is required for IS16GL to remote login. 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: 192.168.10.50 (Please check your DHCP address for this field.) Login name: admin

- 19 -

Default password: 00000000

Tips

SB-3164-G1A3 Series only support SSH for remote control. For using SSH, the IP address and the password is required for login.

2.9 Enclosure

1. RAID light: Green means RAID works well. Red represents RAID failure happening.

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

3. Voltage light: Green is normal. Red represents abnormal voltage status.

4. UPS light: Green is normal. Red represents abnormal UPS status.

5. Fan light: Green is normal. Red represents abnormal fan status.

6. Power light: Green is normal. Red represents abnormal power 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, and it has no space for snapshot and spare. If snapshot function is needed, please create volumes by manual, and refer to section 4.4 for more detail.

IS16GL Quick Install function has a smarter policy. When the system is full inserted with 16 HDD, and all HDD are in the same size, IS16GL Quick Install function lists all possibilities and sizes among different RAID levels, IS16GL 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., 8*200G HDD and 8*80G, IS16GL 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 IS16GL’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.

E.g., user chooses RAID 5 and the controller has 12*200G HDD + 4*80HDD inserted. Then if using all 16 HDD for a RAID 5, then the volume max size is 1200G (80G*15). But in IS16GL, we do smarter check and find out the most efficient use of HDDs, which results controller only use the 200G HDD (Volume size is 200*11=2200G). Then, the volume size is bigger, and full use of HDD capacity.

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.

3.4.4 Login config

Select “Login config” is to set only one admin and set the auto logout timing. The only one admin can prevent multiple users access the same controller in the same time.

1. Auto logout: Options are (1) Disable (2) 5 mins (3) 30 mins (4) 1 hour. When user is no response for a period of time, the system will logout automatically to allow another user to login.

Figure 3.4.4.1

2. Login block: Disable/Enable. When the login block is enabled, the system allows only one user to login/modify the system settings.

3.4.5 Password

Select “Password” is for changing administrator password. The maximum length of admin password is 12 characters.

3.4.7 Mail

Select “Mail” to enter at most 3 mail addresses for receiving the event notification. Some mail servers would check “Mail-from address” and need authentication for anti-spam. Please fill the necessary fields and select “Send test mail” to check whether the email works fine. User can also select which levels of event logs are needed to be sent out by Mail. Default setting is only ERROR and WARNING event logs enabled.
