What Is Storage Resource Management?

1. Store, accumulate money or things. "Civil Assembly Cases, Households and Treasury": "The Household Ministry's Treasury Department is empty, and should be stored." "Clearance Ceremony, the Household Ministry, Kurata, Gatekeeper, and the Minister of the Servant": "Each time a new family enters the warehouse, the warehouse According to the size of the old deposits, the number of beiges is distributed evenly, and the number of beiges in a certain year is stored in a warehouse. It's embarrassing, and a few friends collect money for it, and use it for children's reading. "

For high-definition platform storage, there are generally two types of storage: distributed storage and centralized storage; storage devices generally include: NVR (Network Video Recorder) network video recorders and IPSAN storage devices. Among them, NVR, as an emerging product, plays a very important role in the popularity of network cameras, especially high-definition cameras. Its main function is to record and store network video streams, and provide functions such as real-time display and proxy forwarding. Generally, many Using embedded architecture, hard decoding supports multiple network SD or HD camera access. Take Tiandiweiye s embedded NVR as an example, it can support 16 SD or 8 HD network camera access; embedded hard decoding, real-time preview, video recording; built-in hard disk drive can store; built-in proxy forwarding module can The connected video stream is forwarded; in addition, it has two VGA and BNC output interfaces to decode the display on the wall; it can also be used as a node device to perform node monitoring and distributed storage in the system; another high-definition storage The important device is IPSAN. With the popularization of high definition, IPSAN is playing an increasingly important role in storage. IP SAN adopts the IP architecture of Ethernet transmission, which has good scalability, sharing, and low apportioned application costs. It is multi-channel HD One of the main technologies used in monitoring storage, and most of the storage medium storage uses our common hard disks, and the capacity is generally TB level. As 2TB hard disks or higher-capacity products come into our sight, large HD monitoring systems have PB-level mass storage. The solution is also widely used.

One problem facing high-definition storage is that in high-resolution multi-level networking high-definition projects, if the cost of storage is reduced, on the one hand, this requires the improvement of compression algorithms, and on the other hand, the cost of hard disks and IPSAN is reduced. In terms of algorithms, there are already manufacturers that can implement 2M code streams to transmit 720P high-definition images, so that the storage space for one hour of high-definition is about 1.8G.
