Configuration of Network Interfaces

Fail Over (Default) The system supports the configuration of multiple network interfaces, which enables you to perform Fail Over or Load Balance functions. Fail over ensures server availability to the network. If the primary port is disconnected due to a hardware or cable problem, the secondary port will replace its network identity. 1f the failed port resumes the network connection, it will also resume the role as the primary interface. © oObtainlP address settings automatically via DHCP © Use static IP address Fixed IP Address [7].

• An intelligent software adaptive agent will repeatedly analyze the traffic flow from the server and distribute the packets based on the destination address. Load balance can only occur on Layer 3 routing protocols (IP or NCP IPX). Multicast/Broadcast and non-routing protocols, such as NetBEUI and Microsoft IPX, are transmitted over the primary port.

Standalone Standalone settings enable each port to have a unique IP, which allows users on different network areas to share one ND- 52000 and maintain their independence from one another in the network.

You can also use three disks for RAID 5 and a fourth disk as a backup disk. 1f a disk of RAID 5 volume is damaged, the spare disk can replace that damaged disk, which enhances server stability and efficiency.

RAID 5 Disk Volume Integrate three or more disks into one large disk volume with data protection. Note: When configuring RAID 5 disk volume, at least 3 disks are required. RAID 1 Mirroring Disk Volume Mirroring Disk protects your data by automatically backing up the contents of one disk onto the second disk of a mirrored pair. This protects your data if one of the disks fails. However, the storing capacity is equal to a single disk, as the second disk is used to automatically back up the first one.

RAID 0 Striping Disk Volume Es Integrate two or more disks into one large disk volume with parallel data access.

A network share may not be able to detect a virus without an automatic virus scan function when there is a transfer of infected files. The user computer may have been infected in this situation. To prevent virus infection of the user computers, the system provides a virus scan program to comprehend with available virus scan agent for the best data protection. In System Tools, enter the IP address of the network share and set up the user account and password for the virus scan agent. Specify the IP address of the virus scan agent. When there is a file transfer, the virus scan agent will notify the virus scan software on the system to scan the file.

Installing Virus Scan Agent Make sure the virus scan agent and software are installed on the same computer that performs virus scanning before activating the agent. Follow the following steps to installing Virus Scan Agent:

1. Run the CD-ROM enclosed in the Network Disk Server package.

Appendix B Configuring AD Authentication AD environment mixed mode can be supported by ND-52000. For example, qatest.com.tw and sub2.qatest.com.tw are domains controlled by Windows 2003 server, and subl.qatest.com.tw domain is controlled by Windows 2000 server.

Please make sure you have enabled the Active Directory Service on the Windows Server and check the following items:

DNS Server setting on ND-52000 has to be directed to AD server. ND-52000 and AD server can synchronize only if their time difference is less than 5 minutes. ND-52000 and AD server will synchronize each 5 minute. To configure the settings manually, ND-52000 has to be set as standalone mode and then added to AD domain. When adding ND-52000 to AD domain, please login by domain_name\Username. ND-52000 local user cannot login AD domain. Inter-network segments can be used. If you are using NT Domain, please select standalone mode when you want to upgrade the system, then join AD domain. It is suggested to use Windows 2000 Service Pack 4, or Windows 2003 Service Pack 1. When ND-52000 is added to AD domain, the authority of “everyone” will not work, “everyone” is the original account of ND-52000, but doesn't include AD. Therefore the authority has to be reset. The DNS setting on Windows 2000 server should be added as “Active Directory DNS”, the server should be rebooted after DNS setting is set. You should use the full domain name on the AD setting of ND-52000. For example, if your FQDN name of AD server is “ad.test.com.tw”, you should use “test.com.tw” as the ad domain setting on ND-52000. The DNS setting on AD server should have the IP of AD server itself. You must change the password of “administrator” after you create “Active Directory” service on AD server. The DNS server on the AD Server should have two records on it. For example, AD Server Name: 2003tc.testad.com DNS record on DNS Server 2003tc.testad.com A 192.168.1.100 testad.com A 192.168.1.100 One is “A record” for AD server, and the other is the domain “A record” for DNS queries.
