NAS system:
Network-attached storage systems, file storage, and access all need to go through the local area network and also support the addition of extra storage over Fibre Channel or SCSI-based switches.
NAS Gateway:
That is, no disk file server, it uses a SAN storage array to provide extended storage capacity.
SAN architecture:
Multiple servers in the network are connected to a central disk repository consisting of one or more storage arrays, greatly improving system management and data backup.
Cloud storage:
Through the functions of cluster applications, grid technologies, or distributed file systems, a large number of different types of storage devices in the network are brought together through application software and work together to provide external data storage and service access functions.
HBA:
A pluggable card that connects a host computer to a network/storage device and supports multiple storage network protocols.
IP storage:
Using the IP protocol to connect a remote SAN, in a Fibre Channel SAN, the IP protocol is used to send FC frames in IP packets. For non-fibre Channel SANs, the iSCSI protocol is used to convert SCSI data to IP packets.
NAS storage and cloud storage
RAID:
Independent redundant disk arrays require multiple disks to improve performance and fault redundancy.
LANfree backup:
Back up data to a storage array, tape library, or other storage device without going through a LAN or WAN network.
Fibre Channel:
Data requests are transferred from the server to the disk array, and Fibre Channel switches in the SAN are used to connect servers and storage arrays.
Block-level storage:
Block-level access ensures that network users do not have to manage data when reading/copying files from disk, allowing network administrators to specify where data is stored to address performance issues.
Mainstream NAS and SAN storage
NAS is the fastest growing storage technology. SAN is currently recognized as the most promising storage technology solution. However, in terms of both trends, SAN and NAS will be fully integrated at the application level. It can be said that NAS and SAN technologies have become the mainstream technologies for data backup today. The key lies in how to develop and improve comprehensive and multi-level data backup systems on this basis.
Under the distributed network environment, through professional data storage management software, combined with the corresponding hardware and storage devices, the entire network of data backup for centralized management, in order to achieve automated backup, file archiving, data classification storage and disaster recovery Features. Cloud storage is the latest storage technology to handle large databases. In summary, in the current development of network storage technology, NAS, SAN, and cloud storage are kings of current network storage.
Security monitoring storage products have also undergone a transformation. We can clearly see the changes and development of the combination of video surveillance technology and data storage technology: from closed-circuit television monitoring (CCTV) systems featuring analog signals, to digital or partial Digital video surveillance system in the DVR storage monitoring data; to now booming network video surveillance system, we can easily see that network storage has become the most advanced storage system.
Traditional monitoring matrix and matrix keyboard
The digitized and networked development process is accelerating, and digital video recorders (DVRs), matrixes, and network video recorders (NVRs) have appeared. From the perspective of the entire development trend in the industry, network video surveillance also puts forward two requirements for networked storage: first, network deployment and access; second, networked storage devices. In order to meet the demand for large-capacity centralized storage, the storage device itself must adopt advanced network storage technology to ensure the flexibility of space expansion.
NVR monitoring system application
When it comes to storage products, you have to say DVRs and NVRs. With the trend of high-definition monitoring going high, the concept of HVRs comes into view. It is undeniable that the traditional DVR has accumulated a lot of advanced technology, such as hard disk zero-fragment processing, hard disk rotation, abnormal power-off protection and other technologies, to provide reliable protection for the reliable storage of monitoring images, NVR as a new generation of network monitoring products.
First of all, DVR's excellent features have been fully inherited, and secondly, it has also used the networking features to further enhance the reliability and flexibility of storage. However, according to market research, despite the obvious trend of network monitoring, DVR's development momentum is still good from the point of view of sales and market applications. At the same time, this also reflects the current network storage there are still some drawbacks: First of all, people's innate ideas have been formed; Second, the construction costs of network storage in the early period is too high, although the total cost will decline in the long-term development, but the early needs Investing in complex networks and easily causing port data redundancy;
NVR monitoring system application
Finally, according to the domestic level of informatization, many manufacturers are still not enough to master the technology that generates NVR independently. Therefore, various situations indicate that the current DVR is still the main force of the storage market. High-tech industries should be based on the long-term. Therefore, we cannot deny that NVR will surpass DVRs to occupy the entire storage market in the next few years. Since the spring of this year, the two major domestic DVR manufacturers have not taken the unusual route one after another, causing a storm of DVR price cuts in the industry. Does this also indicate that the DVR will eventually go out of business? We don't know. According to an analysis by the United States Parks Associates survey agency, the global market for network storage devices will reach US$13 million by 2012.
As we all know, high-definition is an important direction for the development of the security industry in the future, and it may also become a big problem for later data storage. The concept of cloud storage is slowly being integrated into the security field. Cloud storage can achieve full virtualization of storage, greatly simplifies application, saves customers' construction costs, and provides stronger storage and sharing capabilities.
Looking at the entire storage market, monitoring the trend of storage networking has become inevitable. Although there are still some deficiencies in technology and market applications, it is a fact that NVRs will replace DVRs. Failure of a generation of products does not mean that it fails. On the contrary, its depravity casts the glory of another product. NVR must also be back to open a new chapter in network storage, let us wait and see!
Detailed security network data storage ten ways
With the continuous infusion of IT elements, the trend of network security in the security industry has become increasingly apparent, and products for network surveillance cameras, network transmission, and network storage have come into being one after another. When people mention security network applications, most of them think of network surveillance cameras. In fact, the composition of the monitoring system is not limited to front-end products. If there is no back-end storage device, then huge image data can only become "clouds." There are 10 technologies related to network storage:
