CAUTION:

CAUTION: (English)

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 Grounding - Reliable grounding 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).

The main purpose of the handles is for rack mount use only. Do not use the handles to carry or transport the systems.

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 more

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:

14 D-Link Document – User Manual

Type

Description

RAID 0

Disk striping.

RAID 6

2-dimensional parity protection over the member disks.

RAID 50

Striping over the member RAID 5 volumes.

RAID 60

Striping over the member RAID 6 volumes.

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.

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.

(initiator)

IP SAN

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

HBA

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.

Quick Setup

Management Interfaces

There are several management methods to manage the storage system, described below.

Web UI

For remote management, the unified storage system uses a web graphic user interface for

operation. It supports most common web browsers. Be sure to connect the LAN cable to the

management port of the system.

The web UI can be accessed via every network interface, but D-Link still defines a management

port. The default IP of the management port setting is DHCP; check the LCM to find the IP address.

If your network does not have DHCP server, you will need to configure a static IP address.

Enter the IP address into your browser to display the authentication screen.

http://<IP Address> (e.g.: http://192.168.10.50)
