You need to set one default NIC (default is Network Card1) to request the network service started by Email and File Transfer Protocol (FTP). Once the card is offline, the system triggers a disconnection alarm.Fault-tolerance: In this mode, the Device communicates with external devices through NIC bonding. You can focus on one host IP address. At the same time, you need to set one main card. Usually there is only one running card (main card). The system will enable the alternate card when the main card malfunctions. The system will not be offline only if all cards are offline. Notice that all cards need to be in the same LAN.Load balance: In this mode, the Device communicates with external devices through NIC bonding. Workload is balanced among all cards. Their network loads are generally the same. The system will not be offline only if all cards are offline. Notice that all cards need to be in the same LAN.Link aggregation: The system uses NIC bonding to realize communication function. All bonded NICs are working together and bearing the network load. The system allocates the corresponding ports to the specified switches according to the port load setting. Once one port link malfunctions, the system stops sending out data from current port. The system can calculate the new load and specify the new port(s) to send out data. The system calculates again to specify the port(s) once the malfunction port becomes available.The Device only supports LACP link aggregation.The Link Aggregation network mode is available when the switch supports link aggregation and is configured with link aggregation.
NIC	When the Network Mode is set as Single NIC, you can bond the current NIC to any other one.Management NIC does not support this function.
IP Version	You can select IPv4 or IPv6 Format. Currently both IP addresses are supported.
MAC Address	Displays the MAC address of the Device.

3.7 IP SAN

Internet Protocol Storage Area Network (IP SAN) is a kind of network storage technology based on IP network. It builds disks and RAID into a virtual logical device (i.e. storage pool) and shares the storage path with other devices through NFS, iSCSI, FTP and SAMBA to enable other devices to store data into the shared path.

For the procedure to configure IP SAN, see Figure 3-39.

3.15 Cluster Service

Cluster function, also known as cluster redundancy function, is a way that can improve device reliability.

Create N main devices and M backup devices in the cluster (N+M cluster), and provide virtual IP address (cluster IP) for unified login and management. Normally, the main devices are working. If the main device breaks down, the backup device not working will replace it to work according to the configuration of the main one and the cluster IP. After the main one is restored, the backup one transmits back the configuration, cluster IP and records during the breakdown, and the main one goes on working.

There is a management server called dispatching console (DSC) in the N+M cluster. DSC performs timely dispatching for the main devices and backup devices. When cluster is created in the Device, the Device is used as a DCS by default.

Dual-control device does not support cluster.

3.15.1 Configuring Cluster

You can create cluster, view cluster information, restore main device and set arbitration IP.

Appendix 2 RAID Introduction

RAID is an abbreviation of Redundant Array of Independent Disks. It combines several independent HDDs (physical HDD) to form a HDD group (logic HDD) to provide more storage capacity and data redundancy.

RAID Level

RAID level refers to the way that the disk array is organized. Different RAID levels have different data protection, availability and performance.

RAID Level	Description	Least Disk No.
RAIDJ	RAIDJ is a data protection method. With erasure codes, you can freely set the number of redundant HDD. Considering the actual scenario, the system provides redundancy of up to 8 HDDs. That is to say, the erasure code RAID can make sure the data will not lose when the 8 HDDs are broken. The security is greatly improved compared with other RAID levels.	3
RAID0	RAID0 consists of striping. Because striping distributes the contents of each file among all HDDs, reads and writes can be done concurrently. Its read and write speed is N times of single HDD (N is the number of disk that consists of RAID0). RAID0 provides no redundancy, and if one HDD fails then all data in the array is lost.	2
RAID1	RAID1 is also called mirroring. Data is written identically to two HDDs, thus improving the system reliability and performance. Its read throughput approaches the sum of throughputs of every HDD in the set, and the write throughput is limited by the slowest HDD. At the same time, RAID has the lowest disk usage, only 50%.	2
RAID2.0	Raid2.0 provides different storage strategies for the same RAID based on your data security requirements. For example, for data of the file system, it offers data security as high as RAID1; for data of ordinary files, it ensures the same security and space utilization of RAID5.	12
RAID5	It distributes data and parity information among the HDDs, and parity information and corresponding data are respectively backed up on different HDDs. Upon failure of a single HDD, subsequent data and parity information can be used to reconstruct the failed data to ensure data integrity.	3
SRAID	Also called super RAID, it is an improved RAID configuration on the basis of RAID5.SRAID can be used immediately after being created. This helps improve security.The reconstruction and write operations are related.If SRAID is disconnected thus unavailable, when the connection restores, it can directly come back to work, with no need of restarting the Device.If one HDD is broken, the system copies the data on this HDD to a new one before deleting it.Read still work if SRAID fails, but part of the data may be lost.	3
RAID6	A parity information HDD is added on the basis of RAID5. The two independent parity systems use different algorithms for enhanced reliability. No data will be lost when the two HDDs fail. But compared with RAID5, it needs to distribute larger space for parity information, so it performs worse in respect of write.	4
RAID10	RAID10 is a combination of RAID1 and RAID0. It owns high read and write capabilities of RAID0, as well as high data protection and restorability of RAID1. But its HDD utilization is as low as RAID1.	4
RAID50	RAID50 is a combination of the RAID5 and RAID0. It has higher fault-tolerance. There is no data loss even one HDD in the set malfunctions.	6
RAID60	RAID60 is a combination of the RAID6 and RAID0. It has higher fault-tolerance and read performance. There is no data loss even two HDDs in one set malfunctions.	8

RAID Capacity Calculation

CapacityN refers to the HDD with the minimum capacity in the set. The capacity shall be subject to the value on the web.

Parameter	Total Capacity of N HDDs
RAIDJ	(N-M) × min (capacityN)M: Select M check disk(s) on the interface.
SRAID	(N-1) × min (capacityN)
RAID60	(N-4) × min (capacityN)
RAID50	(N-2) × min (capacityN)
RAID10	(N/2) × min (capacityN)
RAID6 (N-2) ×	min (capacityN)
RAID5 (N-1) ×	min (capacityN)
RAID1 Min (capacityN)
RAID0	Total capacity of the HDDs in the set

Appendix 3 Glossary

FTP	File Transfer Protocol (FTP) is a protocol of the TCP/IP protocol group. It transfers file from one PC to another, without consideration of the location, connection type, and operating system of the PC.
IP SAN	Internet Protocol Storage Area Network (IP SAN) is an IP-based network storage technology.
iSCSI	Internet Small Computer System Interface (iSCSI) is an internet protocol standard in Ethernet, and an SCSI instruction set for hardware to be used in IP protocol layer. Briefly, iSCSI can realize SCSI protocol in the IP network, so router option is available in high-speed 1000M Ethernet.
LAN	Local Area Network (LAN) is a computer network that interconnects computers within a limited area (such as an office building or a school).
NFS	Network File System (NFS) is a distributed file system protocol. It allows a client computer to access files or peripheral devices of another PC. It is mainly used in UNIX-like platforms.
MTU	Maximum Transmission Unit (MTU) is the size of the largest protocol data unit that can be communicated in a single network layer transaction.
SAMBA	It is a free software that can realize Server Messages Block (SMB) on Linux and Unix systems. It consists of server and client.
SATA	Serial Advanced Technology Attachment (SATA) is a serial HDD interface that can realize serial data transmission. The current released Serial ATA 2.0 enjoys maximum theoretical transfer speed of 300MB/s.
SATA HDD	HDD that adopts SATA standard. Some leading manufacturers such as Seagate, Western Digital, and Hitachi are offering SATA HDDs.
SMART	Self-Monitoring Analysis and Reporting Technology (SMART) is an automatic monitoring and alarming system of HDD status. It monitors and records the HDD through monitoring instructions in the HDD, and compares the monitoring results with the preset security value of the manufacturer. If the monitoring situation is about to exceed or already exceeded the preset value, an alarm will be triggered, and small-scale repair will be initiated. This helps ensure the security of HDD data.
TCP	Transmission Control Protocol (TCP) is a transmission-layer communication protocol that provides reliable and ordered delivery of a stream of bytes.
UDP	User Datagram Protocol (UDP) is a connectionless communication protocol used for processing data packets.
WAN	Wide Area Network (WAN) is a computer network that extends over a large geographical distance. It connects physically disparate LANs and computer systems for the purpose of resource sharing.
Storage Pool	It is a virtual logic device. It can consist of several HDDs and RAID groups. It is a main way to realize virtual storage.
Synchronization	After creating RAID1 or RAID5, and before using it, the system needs to read and write the HDD at a fixed speed and adopts an algorithm to calculate. This process is called synchronization. During synchronization, the system performance speed is very low.
Shared Directory	Local PC access the top path of the shared storage space. You can create, remove, authenticate and set valid user at the storage device. User is only allowed to operate folder and file performance in the under-layer. According to different share protocols, it can be divided into SAMBA share folder, NFS share folder and FTP share folder.
Working Status	It is for RAID6/RAID5/RAID1. It is the RAID status after it completes synchronization operation. When the RAID group is in working status, on the Storage > RAID interface, the RAID device status is clean.
Degraded Status	It is a status after you remove one disk from RAID1/RAID5 (working status) or remove two disks from RAID6. The status shows "degraded".
Manageable Status	It is a device status when controller configure device by web. Actually, when there is no error or damage, the device shall always be in manageable status.
Ready Status	It is a device status when controller access HDD by network. The system is ready to use after you configure correctly in accordance with the Manual. Some non-device error (such as configuration error, hot swap error) may result in device failure. You can configure again to boot up the Device. But data loss may occur during this process.

Appendix 4 Cybersecurity Recommendations

Mandatory actions to be taken for basic device network security:

1. Use Strong Passwords

Please refer to the following suggestions to set passwords:

● The length should not be less than 8 characters;
- Include at least two types of characters; character types include upper and lower case letters, numbers and symbols;
- Do not contain the account name or the account name in reverse order;
- Do not use continuous characters, such as 123, abc, etc.;
- Do not use overlapped characters, such as 111, aaa, etc.;

2. Update Firmware and Client Software in Time

- According to the standard procedure in Tech-industry, we recommend to keep your device (such as NVR, DVR, IP camera, etc.) firmware up-to-date to ensure the system is equipped with the latest security patches and fixes. When the device is connected to the public network, it is recommended to enable the “auto-check for updates” function to obtain timely information of firmware updates released by the manufacturer.

- We suggest that you download and use the latest version of client software.

"Nice to have" recommendations to improve your device network security:

1. Physical Protection

We suggest that you perform physical protection to device, especially storage devices. For example, place the device in a special computer room and cabinet, and implement well-done access control permission and key management to prevent unauthorized personnel from carrying out physical contacts such as damaging hardware, unauthorized connection of removable device (such as USB flash disk, serial port), etc.

2. Change Passwords Regularly

We suggest that you change passwords regularly to reduce the risk of being guessed or cracked.

3. Set and Update Passwords Reset Information Timely

The device supports password reset function. Please set up related information for password reset in time, including the end user's mailbox and password protection questions. If the information changes, please modify it in time. When setting password protection questions, it is suggested not to use those that can be easily guessed.

4. Enable Account Lock

The account lock feature is enabled by default, and we recommend you to keep it on to guarantee the account security. If an attacker attempts to log in with the wrong password several times, the corresponding account and the source IP address will be locked.

5. Change Default HTTP and Other Service Ports

We suggest you to change default HTTP and other service ports into any set of numbers between 1024\~65535, reducing the risk of outsiders being able to guess which ports you are using.

6. Enable HTTPS

We suggest you to enable HTTPS, so that you visit Web service through a secure communication channel.

7. MAC Address Binding

We recommend you to bind the IP and MAC address of the gateway to the device, thus reducing the risk of ARP spoofing.

8. Assign Accounts and Privileges Reasonably

According to business and management requirements, reasonably add users and assign a minimum set of permissions to them.

9. Disable Unnecessary Services and Choose Secure Modes

If not needed, it is recommended to turn off some services such as SNMP, SMTP, UPnP, etc., to reduce risks.

If necessary, it is highly recommended that you use safe modes, including but not limited to the following services:

• SNMP: Choose SNMP v3, and set up strong encryption passwords and authentication passwords.
• SMTP: Choose TLS to access mailbox server.
• FTP: Choose SFTP, and set up strong passwords.
• AP hotspot: Choose WPA2-PSK encryption mode, and set up strong passwords.

10. Audio and Video Encrypted Transmission

If your audio and video data contents are very important or sensitive, we recommend that you use encrypted transmission function, to reduce the risk of audio and video data being stolen during transmission.

Reminder: encrypted transmission will cause some loss in transmission efficiency.

11. Secure Auditing

• Check online users: we suggest that you check online users regularly to see if the device is logged in without authorization.
• Check device log: By viewing the logs, you can know the IP addresses that were used to log in to your devices and their key operations.

12. Network Log

Due to the limited storage capacity of the device, the stored log is limited. If you need to save the log for a long time, it is recommended that you enable the network log function to ensure that the critical logs are synchronized to the network log server for tracing.

13. Construct a Safe Network Environment

In order to better ensure the safety of device and reduce potential cyber risks, we recommend:

• Disable the port mapping function of the router to avoid direct access to the intranet devices from external network.
• The network should be partitioned and isolated according to the actual network needs. If there are no communication requirements between two sub networks, it is suggested to use VLAN, network GAP and other technologies to partition the network, so as to achieve the network isolation effect.
• Establish the 802.1x access authentication system to reduce the risk of unauthorized access to private networks.
• Enable IP/MAC address filtering function to limit the range of hosts allowed to access the device.
