Safety Information

Technician Notes

Warning

Only authorized technicians should attempt to repair this equipment. All trouble shooting and repair

procedures allow only module replacement. Because of the complexity of the individual boards and sub-

assemblies, no one should attempt to make repairs at the component level or make modifications to any

printed wiring board. Improper repairs can create a safety hazard.

To reduce the risk of personal injury from electric shock and hazardous energy levels, do not exceed the

level of repairs specified in these procedures.

Caution

The system is designed to be electrically grounded. To ensure proper operation, plug the AC power cord

into a properly grounded AC outlet only.

Electrostatic Discharge

Electrostatic discharge (ESD) can damage static sensitive devices or micro circuitry. Proper packaging

and grounding techniques are required to prevent damage.

• Transport products in static safe containers such as conductive tubes, bags or boxes.

• Keep electrostatic-sensitive parts in their containers until they arrive at a static free work area.

• Use a wrist strap connected to the work surface as well as properly grounded tools and

equipment.

• Keep the area free of nonconductive materials such as ordinary plastic assembly aids and foam

packing.

• Ensure proper grounding before touching a static-sensitive component or assembly.

• Avoid touching pins, leads, or circuitry.

• Always place drives with printed circuit board (PCB) assembly-side down.

Warning

Rack Warnings

If you plan to rack mount the iSCSI RAID Storage, Fibre RAID Storage or the Expansion RAID Storage

System, please follow the rack manufacturer’s safety instructions. Install the enclosure only in a rack that

has been properly secured in an area with suitable environmental conditions.

Caution

Have someone assist you during physical installation.

Caution

To properly ventilate the system, you must provide at least 7.6 cm of clearance at the front and back of

the server.

Warning

To reduce the risk of personal injury or damage to equipment, always ensure that the rack is adequately

stabilized prior to extending a component outside the rack. A rack may become unstable if more than one

component is extended. Extend only one at a time.

System Warnings

Warning

To reduce the risk of personal injury from hot surfaces, allow the hot-plug disk modules and other system

modules to cool before touching them.



Warning

To reduce the risk of electric shock or damage to the equipment:

• Do not disable the power cord grounding plug. The grounding plug is an important safety feature.

• Ensure the power cord is inserted into a grounded electrical outlet that is easily accessible at all

times.

• Unplug the power cord from the power supply module to shut off power to the equipment.

Caution

Protect the storage system from power fluctuations and temporary power interruptions with a regulating

uninterruptible power supply (UPS). This device protects the hardware from damage caused by power

surges and voltage spikes and keeps the system operational during a power failure.

Caution

The storage system must always be operated with all hot plug modules installed or slot covers in place to

ensure proper cooling.

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 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

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

RAID 1

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

hard drives.

N-way mirror

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

RAID 3

Striping with parity on the dedicated disk. RAID 3 needs at

least three hard drives.

RAID 5

Striping with interspersed parity over the member disks.

RAID 3 needs at least three hard drives.

RAID 6

2-dimensional parity protection over the member disks.

RAID 6 needs at least four hard drives.

RAID 0+1

Mirroring of the member RAID 0 volumes. RAID 0+1 needs

at least four hard drives.

RAID 10

Striping over the member RAID 1 volumes. RAID 10 needs

at least four hard drives.

RAID 30

Striping over the member RAID 3 volumes. RAID 30 needs

at least six hard drives.

RAID 50

Striping over the member RAID 5 volumes. RAID 50 needs

at least six hard drives.

RAID 60

Striping over the member RAID 6 volumes. RAID 60 needs

at least eight hard drives.

JBOD

The abbreviation of “Just a Bunch Of Disks”. JBOD needs

at least one hard drive.

1.2.2 Volume relationship

The below graphic is the volume structure which is designed for the iSCSI

and Fibre RAID Storage Systems. It describes the relationship of RAID

components. One RG (RAID Group) consists of a set of VDs (Virtual Disks)

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.

Storage Concepts

1.3.1 iSCSI

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 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 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

RAM

Cache Volume

LUN 1 LUN 2 LUN 3

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.

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).

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.

1.3.2 Fibre Channel

Fibre channel started use primarily in the supercomputer field, but has

become the standard connection type for storage area networks (SAN) in

enterprise storage.

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 commands or bridges to an attached storage device.
