Security cloud storage types are divided into which categories

In the security industry actually encountered a variety of storage systems, can be roughly divided into traditional storage, IT cloud storage, general cloud storage, security cloud storage four.

Traditional storage is mainly IPSAN/NAS and NVR/CVR convergence business layer to achieve the N + 0 mode. IPSAN behind the mounted disk expansion cabinet mode, to provide a single machine within the disk level raid level of reliability, the business system to be mounted separately, the use of complex, fault-tolerant poor.

NVR/CVR N+0 is to be realized in the business layer of a single machine failure can still write, for the unawareness of the situation will be the concept of cloud storage to protect, but still can not solve a series of problems such as storage failures and elastic expansion.

IT cloud storage mainly refers to IT vendors in the traditional IPSAN/NAS breakthrough to provide NAS cluster/distributed block storage. More as a general IT application scenario to the database and virtual machines to provide block devices, enterprise applications by directory space management to provide permissions and file read and write.

General cloud storage mainly refers to the general-purpose distributed storage system in accordance with a common interface to provide a write-multiple-read capability, and general big data components to open up, can be used as the underlying storage system.

Mainly S3 form of object storage and HDFS-like file system, the two in the operation of the semantics of the difference lies in one is operated according to the object mode, one is operated according to a similar traditional file system mode (posix-like semantics but non-standard).

Security cloud storage refers to the deepening of the design for the security industry video picture business scenarios, based on the distributed architecture to achieve the file storage system can provide object semantics or file semantics.

With high concurrent writing, high storage utilization, high reliability storage and other characteristics, support read-while-write, multi-network video, picture processing, file locking and other functions, to meet the security different business scenarios 7x24 hours uninterrupted application requirements.
