Description
Technical field
The present invention relates to memory system technologies fields, and in particular to a kind of near line disk array library with contact point.
Background technique
A large amount of data storage requirement is produced in digitlization process, wherein a large portion is derived from sensor, especially
It is imaging sensor.Video monitoring is the typical case of imaging sensor, and workflow can be divided into two parts, first is that continuously
Journal video data stream without interruption；Second is that being transferred to the video recorded.Due to the operation transferred be it is random,
It is to be triggered by external emergency event, therefore, the data access process of video monitoring has the characteristic of " sequential write, random write ".
Wherein sequential write is continual continuous process, and random write infrequently occurs, and is to transfer recorded time sequence at random
The operation of data in one time window of column.Very universal, the almost all of sensor number of similar this working law
There are similar characteristics according to record.Similar one application is data backup therewith, and the process of backup is also sequential write, the mistake of recovery
Journey is that sequence is read or selective part order is read.It is the application of video monitoring class that we, which are referred to as these applications, above.
Video monitoring class needs a large amount of memory space to support using generated data, currently the most common technology solution
Certainly scheme is using various disk arrays.Disk array is the optimal organizational form of " random write, random write ", every piece of drive in array
Dynamic device can be written into any position in disk array all in work armed state, data at any time, can also be from disk array
Any position called data in space.Disk array storage system is usually by disc driver and peripheral control system in the prior art
System is constituted.Loss of data when single disc driver appears corrupted thereon in order to prevent, peripheral control system can be according to skills
Art requires to use various redundancies, such as the correcting and eleting codes (Erasure Coding) in RAID5, RAID6 and cloud storage system
Deng.With the increase of disc driver quantity, the complexity of peripheral control system and the quantity of connecting line also increase sharply.Periphery
The core of control system is server, and server can be connected outside by bus external connection disc driver reaching server
When the upper limit of portion's interface quantity, some interfaces can also be increased by expander, nevertheless, every server can connect
Disc driver quantity be still limited.When needing to manage greater number of disc driver, it is necessary to use more
Server, in order to coordinate and manage these servers, it is also desirable to more complicated software.
With the application popularization that high-definition camera is first-class, typical monitoring storage demand is often hundreds of TB to number PB.For
Storage demand big so usually will include multiple servers and complicated software in solution, so that large-scale monitoring data
The unit carrying cost of storage is difficult to further decrease, and the Total Cost Ownership of video monitoring also will be maintained at higher level
On.
Nearline storage is one of three kinds of storage modes of data storage, and with respect to on-line storage, cost is relatively low, phase for nearline storage
It is good to offline storage convenience, and access speed is between on-line storage and offline storage.Entitled Near-line disk base,
The patent that number of patent application is 201310220277.0 discloses following technical solution: a kind of Near-line disk base comprising cabinet, is set
Server, manipulator and several disk storehouses drawer in cabinet are set, each disk storehouse drawer includes multiple disk storehouses, each magnetic
Pan Cang has accommodation groove, the disk being arranged in accommodation groove, the disk contact point and manipulator contact point be connected with disk, magnetic
Disk storehouse drawer is arranged in the one or both sides of manipulator, and manipulator makes the probe of manipulator by horizontal movement and vertical movement
Component and the manipulator in disk storehouse contact point contact, realize the connection of disk and server.Disk contact point is contacted comprising signal
Point and contact point of power source, manipulator contact point also include corresponding with the signal contact point of disk, the contact point of power source of disk
The signal contact point of manipulator and the contact point of power source of manipulator, when the probe component of manipulator is contacted with the manipulator in disk storehouse
When point contact, realize that power supply conducting is connected with signal.
But the application emphasis of foregoing invention is to manage a large amount of offline disks, that is to say, that foregoing invention is usually will
It has write full but has realized near line management by electromechanical automatic mode without common disc driver, be not suitable for having
The video monitoring class application of " sequential write, random write " characteristic.
To achieve the effect that further reduce the cost, improving reliability, reduce power consumption and improve system maintainability, have
Necessity optimizes typical disk array form in the prior art, provides a kind of suitable for the close of video monitoring class application
Line storage device.
