1, safe birth mass storage building
Throughout the country as "harmonious society Safe City "The acceleration of construction of each project control point tens of thousands of peace, or even hundreds of thousands, according to the government, the public security department requirements, safe city of at least save the video surveillance data more than 15 days, the resulting mass of data is very impressive , the traditional DVR (DVR / NVR) can not meet actual needs, but as the carrier of its mass storage?? Storage systems are often due to the performance, price, compatibility, security and other factors into troubled companies is a difficult problem.
2, storage Technology And structure analysis
Traditional data storage technology is more mature and complete, the current mainstream memory architecture with NAS, SAN two, while the SAN can be divided into two FCSAN and IPSAN. Following the industry for monitoring the characteristics of storage demand, combined with the user's actual application, these three storage architectures in a more and selection.
2.1NAS storage architecture 2.1.1 file-level data storage
NAS device is the most important applications Enterprise Or departmental file sharing. As the NAS itself is a thin server has its own operating system and file system that can connect directly with the local area network to provide file-level data sharing, but the NAS device can not be the server's local hard drive, can not provide block storage.
2.1.2 limited bandwidth NAS is transmitted in the LAN, and has its own operating system and file system, these factors will lead to lower bandwidth NAS device to increase the NAS device to read and write response time.
2.2FCSAN storage architecture 2.2.1 Performance FCSAN greatest advantage is its excellent performance. The current mainstream FC Product The bandwidth of 2Gb / s, 4Gb / s products have been fairly common, this is a sign of FCSAN performance. The high-performance optical disk itself, but also for the FC Disk array Provides the basis for high-speed operation.
2.2.2 costly FCSAN bring high performance is another feature of high-cost, from fiber to fiber disk array itself, and then to optical switching equipment, fiber HBA cards and other peripheral equipment costs are high, and bring fiber-optic disk array The management and maintenance costs will also be spending a small fortune in the user.
2.3IPSAN storage architecture IPSAN used in the iSCSI protocol is actually an Internet protocol, is a SAN structure. By the SCSI protocol encapsulated in IP packets, making SCSI protocol to the LAN / WAN in for transmission.
2.3.1IPSAN features 1) the definition for storage area networks (SANs). IPSAN is a SAN, achieved through IP SAN, which IPSAN.
2) required to support database application block-based storage. Although transmission through the IP, but iSCSI is block-based storage, which is different from file-based NAS storage.
3) based on TCP / IP, iSCSI is encapsulated in the IP packet for transmission, so it has a TCP / IP all the advantages, such as reliable transmission can be routing.
4) the establishment and management of IP-based storage devices, Host And the client connection is established between the widely used, familiar to everyone on open standards
5) to provide advanced IP routing, management and Security Tool. Most existing network management tools can be used to manage IPSAN.
