Chapter 1 Overview

1.1 Features

iStoragePro controller can provide non-stop service with a high degree of fault

tolerance by using iStoragePro RAID technology and advanced array management features.

The controller of iR16IS4ER connects to the host system by iSCSI interface. It can be configured to numerous RAID level. The controller provides reliable data protection for servers by using RAID 6. The RAID 6 allows two HDD failures without any impact on the existing data. Data can be recovered from the existing data and parity drives. (Data can be recovered from the rest drives.)

Front View Rear View

Figure 1.1.1 iR16IS4ER

Snapshot-on-the-box (iSnap) 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. Snapshot-on-the-box can keep up to 32 snapshots for one logical volume. Rollback feature is provided for restoring the previous-snapshot data easily while continuously using the volume for further data access. The data access which includes read / write is working as usual without any impact to end users. The "on-the-box" implies that it does not require any proprietary agents installed at host side. The snapshot is taken at target side. 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.

iStoragePro controller 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.

1.2 RAID concepts

RAID is the abbreviation of “Redundant Array of Independent Disks”. The basic idea

of RAID is to combine multiple drives together to form one large logical drive. This RAID drive obtains performance, capacity and reliability than a single drive. The operating system detects the RAID drive as a single storage device.

1.2.1 Terminology

The document uses the following terms:

• Part 1: Common

RAID

Redundant Array of Independent Disks. There are different

RAID levels with different degree of data protection, data availability, and performance to host environment.

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

LUN

Raid Group. A collection of removable media. One RG consists

of a set of VDs and owns one RAID level attribute.

Virtual Disk. Each RD could be divided into several VDs. The VDs from one RG have the same RAID level, but may have different volume capacity.

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

- 11 -

iR16IS4ER

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

GUI

RAID cell

Graphic User Interface.

When creating a RAID group with a compound RAID level, such as 10, 30, 50 and 60, this field indicates the number of subgroups in the RAID group. For example, 8 disks can be grouped into a RAID group of RAID 10 with 2 cells, 4 cells. In the 2-cell case, PD {0, 1, 2, 3} forms one RAID 1 subgroup and PD {4, 5, 6, 7} forms another RAID 1 subgroup. In the 4-cells, the 4 subgroups are PD {0, 1}, PD {2, 3}, PD {4, 5} and PD {6,7}.

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.

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.

SCSI

SAS

S.M.A.R.T.

WWN

Set the volume to be Read-Only.

Dedicated Spare disks. The spare disks are only used by one

specific RG. Others could not use these dedicated spare disks for any rebuilding purpose.

Global Spare disks. GS is shared for rebuilding purpose. If some RGs 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.

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.

1.2.2 RAID levels

There are different RAID levels with different degree of data protection, data availability, and performance to host environment. The description of RAID levels are on the following:

RAID 0

RAID 1

N-way mirror

RAID 3

RAID 5

RAID 6

Disk striping. RAID 0 needs at least one hard drive.

Disk mirroring over two disks. RAID 1 needs at least two hard drives.

Extension to RAID 1 level. It has N copies of the disk.

Striping with parity on the dedicated disk. RAID 3 needs at least three hard drives.

Striping with interspersed parity over the member disks. RAID 3 needs at least three hard drives.

2-dimensional parity protection over the member disks. RAID 6 needs at least four hard drives.

RAID 0+1

RAID 10

Mirroring of the member RAID 0 volumes. RAID 0+1 needs at least four hard drives.

Striping over the member RAID 1 volumes. RAID 10 needs at least four hard drives.

- 13 -

iR16IS4ER

RAID 30

RAID 50

RAID 60

JBOD

Striping over the member RAID 3 volumes. RAID 30 needs at least six hard drives.

Striping over the member RAID 5 volumes. RAID 50 needs at least six hard drives.

Striping over the member RAID 6 volumes. RAID 60 needs at least eight hard drives.

The abbreviation of “Just a Bunch Of Disks”. JBOD needs at least one hard drive.

1.2.3 Volume relationship

The below graphic is the volume structure which iStoragePro has designed. It describes the relationship of RAID components. One RG (RAID group) consists of a set of VDs (Virtual Disk) and owns one RAID level attribute. Each RG can be divided into several VDs. The VDs in one RG share the same RAID level, but may have different volume capacity. All VDs share the CV (Cache Volume) to execute the data transaction. LUN (Logical Unit Number) is a unique identifier, in which users can access through SCSI commands.

1.3 iSCSI concepts

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.

- 14 -

iR16IS4ER

IP SANs are true SANs (Storage Area Networks) which allow several 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, it can be used by any type of network (Ethernet, Fast Ethernet, Gigabit Ethernet, and 10 Gigabit Ethernet) and combination of operating systems (Microsoft Windows, Linux, Solaris, Mac, 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 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 performs SCSI command or bridge to an attached storage device.

Figure 1.3.1

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, Solaris and Mac provide iSCSI initiator driver. Please contact iStoragePro for the latest certification list. Below are the available links:

3.2 How to use the system quickly

The following methods will describe the quick guide to use this controller.

3.2.1 Quick installation

- 23 -

iR16IS4ER

It is easy to use “Quick install” to create a volume. It uses whole physical disks to create a RG; the system will calculate maximum spaces on RAID levels 0 / 1 / 3 / 5 / 6 / 0+1. “Quick install” will occupy all residual RG space for one VD, and it has no space for snapshot and spare. If snapshot is needed, please create volumes by manual, and refer to section 5.4 for more detail. If some physical disks are used in other RGs, “Quick install” can not be run because the operation is valid only when all physical disks in this system are free.

Step 1: Click “Quick install”, then choose the RAID level. After choosing the RAID level, then click “Confirm”. It will link to another page.

Figure 3.2.1.1

Step 2: Confirm page. Click “Confirm” if all setups are correct. Then a VD will be

created.

Step 3: Done. You can start to use the system now.

Figure 3.2.1.2

(Figure 3.2.1.2: A virtual disk of RAID 0 is created and is named by system itself.)

3.2.2 Volume creation wizard

“Volume create wizard” has a smarter policy. When the system is inserted with

some HDDs. “Volume create wizard” lists all possibilities and sizes in different RAID levels, it will use all available HDDs for RAID level depends on which user chooses. When system has different sizes of HDDs, e.g., 8*200G and 8*80G, it lists all possibilities and combination in different RAID level and different sizes. After user

iR16IS4ER

chooses RAID level, user may find that some HDDs are available (free status). The result is using smarter policy designed by iStoragePro. It gives user:

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

2. The fewest disk number for RAID level / volume size. E.g., user chooses RAID 5 and the system 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). By the wizard, we 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 “/ Volume configuration / Volume create wizard” and then choose the RAID level. After the RAID level is chosen, click “Next”. Then it will link to next page.

Figure 3.2.2.1

Step 2: Please select the combination of the RG capacity, or “Use default algorithm” for maximum RG capacity. After RG size is chosen, click “Next”.

Figure 3.2.2.2

Step 3: Decide VD size. User can enter a number less or equal to the default number.

Then click “Next”.

4.2 System configuration

“System configuration” is designed for setting up the “System setting”, “IP address”, “Login setting”, “Mail setting”, and “Notification setting”.

Figure 4.2.1

4.2.1 System Setting

“System setting” can setup system name and date. Default “System name” is

composed of model name and serial number of this system.

Figure 4.2.1.1

- 28 -

iR16IS4ER

Check “Change date and time” to set up the current date, time, and time zone before using or synchronize time from NTP (Network Time Protocol) server. Click “Confirm” in System indication to turn on the system indication LED. Click again to turn off.

4.2.2 IP address

Figure 4.2.2.1

“IP address” is for changing IP address for remote administration usage. There are

two options, DHCP (Get IP address from DHCP server) and static IP. The default setting is DHCP. User can change the HTTP, HTTPS, and SSH port number when the default port number is not allowed on host.

4.2.3 Login setting

“Login setting” can set single admin, auto logout time and admin / user password.

The single admin is to prevent multiple users access the same system in the same time.

1. Auto logout: The options are (1) Disabled; (2) 5 minutes; (3) 30 minutes; (4) 1 hour. The system will log out automatically when user is inactive for a period of time.

- 29 -

iR16IS4ER

2. Login lock: Disabled or Enabled. When the login lock is enabled, the system allows only one user to login or modify system settings.

Figure 4.2.3.1

Check “Change admin password” or “Change user password” to change admin or user password. The maximum length of password is 12 characters.

4.2.4 Mail setting

“Mail setting” can enter 3 mail addresses for receiving the event notification. Some

mail servers would check “Mail-from address” and need authentication for antispam. Please fill the necessary fields and click “Send test mail” to test whether email functions are available. User can also select which levels of event logs are needed to be sent via Mail. Default setting only enables ERROR and WARNING event logs. Please also make sure the DNS server IP is well-setup so the event notification mails can be sent successfully.
