UL statement
Rack Mount Instructions - The following or similar rack-mount instructions are included with the
installation instructions:
1. Elevated Operating Ambient - If installed in a closed or multi-unit rack assembly, the
operating ambient temperature of the rack environment may be greater than room ambient.
Therefore, consideration should be given to installing the equipment in an environment
compatible with the maximum ambient temperature (Tma) specified by the manufacturer.
2. Reduced Air Flow - Installation of the equipment in a rack should be such that the amount of
air flow required for safe operation of the equipment is not compromised.
3. Mechanical Loading - Mounting of the equipment in the rack should be such that a
hazardous condition is not achieved due to uneven mechanical loading.
4. Circuit Overloading - Consideration should be given to the connection of the equipment to
the supply circuit and the effect that overloading of the circuits might have on overcurrent
protection and supply wiring. Appropriate consideration of equipment nameplate ratings
should be used when addressing this concern.
5. Reliable Earthing - Reliable earthing of rack-mounted equipment should be maintained.
Particular attention should be given to supply connections other than direct connections to
the branch circuit (e.g. use of power strips).
CAUTION: The main purpose of the handles is for rack mount use only. Do not
use the handles to carry or transport the systems.
The ITE is not intended to be installed and used in a home, school or public area accessible to the
general population, and the thumbscrews should be tightened with a tool after both initial
installation and subsequent access to the panel.
Warning: Remove all power supply cords before service
This equipment intended for installation in restricted access location.
Access can only be gained by SERVICE PERSONS or by USERS who have been instructed
about the reasons for the restrictions applied to the location and about any precautions that
shall be taken.
Access is through the use of a TOOL or lock and key, or other means of security, and is
controlled by the authority responsible for the location.

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.
RAID Levels
There are various RAID levels with different degrees of data protection, data availability, and
performance. A description of supported RAID levels follow:
Type
Description
Min. No. of Drives
RAID 0
Disk striping.
1
RAID 1
Disk mirroring over two disks.
2
RAID 5
Striping with interspersed parity over the member disks.
3
RAID 6
2-dimensional parity protection over the member disks.
4
RAID 50
Striping over the member RAID 5 volumes.
6
RAID 60
Striping over the member RAID 6 volumes.
8
NAS Concepts
NAS (Network-Attached Storage) is file-level computer data storage connected to a computer
network providing data access to heterogeneous clients. NAS uses file-based protocols such as NFS
(popular on UNIX systems), SMB/CIFS (Server Message Block/Common Internet File System) (used
with MS Windows systems), or AFP (used with Apple Macintosh computers). NAS units rarely limit
clients to a single protocol.

Copyright@1993~2013 Advanced Computer & Network Corp. All Rights Reserved.
19
U Series User Manual
NAS provides both storage and a file system. This is often contrasted with SAN (Storage Area
Network), which provides only block-based storage and leaves file system concerns on the "client"
side. SAN protocols are SCSI, Fibre Channel, iSCSI, ATA over Ethernet (AoE), or HyperSCSI.
One way to loosely conceptualize the difference between a NAS and a SAN is that a NAS appears
to the client OS (operating system) as a file server (the client can map network drives to shares on
that server) whereas a disk available through a SAN still appears to the client OS as a disk, visible in
disk and volume management utilities (along with client's local disks), and available to be
formatted with a file system and mounted.
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.
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.

U Series User Manual
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.
