Description
Technical field
The present invention relates to sata port multiplexing technology field more particularly to a kind of sides for sata port multiplex optimization
Method.
Background technique
In the storage equipment of China, the usage amount of video monitoring storage is maximum, simultaneously for the tolerance journey of data safety
Spend highest.Therefore, sata port multiplexing technology is stored applied to video monitoring, is a trend.If the end SATA can be promoted
Stability of the mouth multiplexing under FIS mode, then application of this scheme in video storage will be more and more.
Sata port multiplex mode is mainly used for 16 disk positions storage equipment, for such equipment, according to 4TB hard disk, wound
A RAID5 (comprising a HotSpare disk) is built, equipment effective storage capacity is 50TB, video monitoring medium scale for one
Scene, if storage time is set as 14 days, then storage performance demand is 40MB/S.It can be seen that most of video monitoring storages,
In practical business, needing performance requirement to be achieved is 43MB/S.
The SATA interface bandwidth of mainstream has reached 300MB/S at present, and therefore, the physical transfer bandwidth of sata port multiplexing is
300MB/S will not become system bottleneck.However, after hard disk is RAID5, in video monitoring service, if to reach 43MB/S
Memory bandwidth, it usually needs 5-6 block hard disk, without using whole hard disks.
Sata port multiplexing technology can be realized by both of which:
1. switch mode (Command-based switching) synchronization based on order, host is only and one piece hard
Disk carries out data transmission, and before the command queue of this hard disk not yet completes, host is issued without other hard disks of normal direction and instructed.Therefore this mould
Formula is unable to fully using SATA interface bandwidth, and storage transmission performance is general, weak to bandwidth demand suitable for strong to capacity requirement
Application environment.But due to using simultaneously operating, this quasi-mode is not suitable for and RAID environment, therefore, current video
Monitoring business seldom uses the multiplexed port scheme based on order exchange.
Frame Information Structure switch mode 2. (Frame Information Structure) synchronization, host can be to
Multiple drivers simultaneously provide high performance storage connection, and ensure the data flow of stable equilibrium by arbitration algorithm.With base
Different in the exchange of order, the exchange based on FIS can collect multiple read operations to make full use of host link available higher
Bandwidth.Since FIS uses asynchronous work mode, it can be applied under RAID environment, still, compare SAS hardware, SATA
The stability of hardware is relatively weak, and under FIS mode, the data of all hard disks all pass through SATA interface and interact with host, at this time
There are hidden danger for the stability of SATA interface.
Summary of the invention
In view of the above drawbacks of the prior art, technical problem to be solved by the invention is to provide one kind to be directed to the end SATA
The method of mouth multiplex optimization, so as to solve the deficiencies in the prior art.
To achieve the above object, the present invention provides a kind of methods for sata port multiplex optimization, which is characterized in that
Including two kinds of implementation modes:
Data disks in each SATA group are divided into first and second liang after storage equipment creates RAID5 by S1, static poll pattern
This two group hard disc will be written in group, video data according to time threshold, timesharing, with when threshold 7 days alternate cycles processing；
S2, dynamical feedback mode after storage equipment creates RAID5, in first time threshold, run totally, count
To average memory bandwidth n, and in each SATA interface, the state value of the temperature of each data disks and delay from low to high into
Row sequence, is denoted as S1 { a1 ... a4 }, S2 { a1 ... a4 }, S3 { a1 ... a4 }, S4 { a1 ... a4 }.
Further, according to the size of average memory bandwidth n, with when loop to determine processing within threshold 7 days, using state value as standard
Determine the number for retaining hard disk, comprising:
A, n < 25MB/S: each group reserved state is worth 1 piece of minimum hard disk；
B, 25≤n < 50MB/S: each group reserved state is worth 2 pieces of minimum hard disks；
C, 50≤n < 80MB/S: each group reserved state is worth 3 pieces of minimum hard disks；
D, whole hard disks n > 80MB/S: are used.
The beneficial effects of the present invention are:
The present invention can the multiplexing quantity to sata port control, so that it is reduced to 1-2 by 4, to be promoted
The stability and disk whole service life of storage system.It, can when carrying out video recording inquiry meanwhile after data timesharing write-in
To realize a degree of read and write abruption, that is, when inquiring the data of a time cycle, the hard disk currently recorded a video,
Read operation is not had, guarantees that hard disc magnetic head is not read and write simultaneously, to promote the service life of hard disk.
It is described further below with reference to technical effect of the attached drawing to design of the invention, specific structure and generation, with
It is fully understood from the purpose of the present invention, feature and effect.
Detailed description of the invention
Fig. 1 is the multiplexed port figure based on order switch mode.
Fig. 2 is the multiplexed port figure based on Frame Information Structure switch mode.
Fig. 3 is the Frame Information Structure switch mode multiplexed port figure after optimization of the invention.
Specific embodiment
As shown in figure 3, a kind of method for sata port multiplex optimization, which is characterized in that including two kinds of implementation modes:
Data disks in each SATA group are divided into first and second liang after storage equipment creates RAID5 by S1, static poll pattern
This two group hard disc will be written in group, video data according to time threshold, timesharing, with when threshold 7 days alternate cycles processing；This mode it is excellent
Point be realize it is simple, it is stable, but it is inadequate to control precision, can be into if storage system is in the case of low-pressure
One step reduces the quantity of work hard disk, thus preferably lifting system stability；
S2, dynamical feedback mode after storage equipment creates RAID5, in first time threshold, run totally, count
To average memory bandwidth n, and in each SATA interface, the state value of the temperature of each data disks and delay from low to high into
Row sequence, is denoted as S1 { a1 ... a4 }, S2 { a1 ... a4 }, S3 { a1 ... a4 }, S4 { a1 ... a4 }.
Further, according to the size of average memory bandwidth n, with when loop to determine processing within threshold 7 days, using state value as standard
Determine the number for retaining hard disk, comprising:
A, n < 25MB/S: each group reserved state is worth 1 piece of minimum hard disk；
B, 25≤n < 50MB/S: each group reserved state is worth 2 pieces of minimum hard disks；
C, 50≤n < 80MB/S: each group reserved state is worth 3 pieces of minimum hard disks；
D, whole hard disks n > 80MB/S: are used.
The preferred embodiment of the present invention has been described in detail above.It should be appreciated that those skilled in the art without
It needs creative work according to the present invention can conceive and makes many modifications and variations.Therefore, all technologies in the art
Personnel are available by logical analysis, reasoning, or a limited experiment on the basis of existing technology under this invention's idea
