Description
Technical field
Product scope is stored the present invention relates to controller, and in particular to a kind of side of dual controller storage extension cabinet cascade
Method.The present invention is by inventing a kind of new dual controller extension cabinet cascade system, it is possible to achieve the fault-tolerant company of different SAS domains
Connect, when wherein one link breaks down, controller stores main cabinet can normally access extension cabinet by redundant link, ensure
Front-end business is normally run.
Background technology
With the arrival in big data epoch, data volume expands rapidly and becomes big, storage and processing to mass data
Decide the future development of enterprise.This requires storage product to provide the memory space of magnanimity, generally, storage production
Product increase storage system capacity by cascading extension cabinet.
SAS (Serial Attached SCSI) is Serial Attached SCSI (SAS), is the SCSI technologies of a new generation, and current trend
Serial ATA (SATA) hard disk it is identical, be all to use serial technology to obtain higher transmission speed, and pass through to shorten and connect
Tie lines improves inner space etc..SAS is the new interfaces developed after parallel SCSI interface.The design of this interface is to change
Efficiency, availability and the extendibility of kind storage system, and the compatibility with SATA hard disc is provided.
RAID (Redundant Array of Independent Disk raid-arrays) technology is that California is big
Learn Berkeley and propose within 1987 that RAID technique can make data safer.RAID technique is initially small in order to combine
Inexpensive disk replaces big expensive disk, at the same time it is wished that the access to data will not be made to suffer a loss and develop during disk failure
The Data Protection Technologies of certain level.RAID is exactly a kind of redundant array being made up of polylith inexpensive disk, under an operating system
It is to occur as an independent large storage facilities.RAID can give full play of the advantage of polylith hard disk, can be lifted hard
Disk speed, increase capacity enough ensures Information Security there is provided fault tolerance, it is easy to the advantage of management, goes out in any one piece of hard disk
Work is may continue in the case of existing problem, the influence for the hard disk that will not be damaged.For needing to increase storage system capacity
And it is desirable that increase Information Security situation can use which.The simple disk bundles of JBOD (Just Bundle Of Disks)
Tie up, also commonly known as Span.JBOD is not the RAID of standard, and it is simply just proposed in recent years by some producers, and by
It is widely used.Span is that logically several physical disks are connected in series together one by one, so as to provide one big patrol
Collect disk.The simple storage since first disk of data on Span, after the memory space of first disk is finished, then
The data storage since disk below successively.Its access performance is fully equivalent to the accessing operation to single disk.Usual feelings
Under condition, it is forward link cascade to store main cabinet and JBOD, when wherein one JBOD (such as JBOD 3) is broken down, JBOD 3 it
All JBOD afterwards can not be accessed normally.
For this problem, the present invention provides a kind of method of dual controller storage extension cabinet cascade, all the way extension cabinet from
Store main cabinet to start, then from the close-by examples to those far off connect extension cabinet.The connection of another road extension cabinet then draws near company from opposite direction
Extension cabinet is connect, redundant link is formed, when a wherein link failure, expansion can normally be accessed by redundant link by storing main cabinet
Showcase, ensures that front-end business is normally run, and while storage system capacity is improved, ensures the safety of data.
The content of the invention
Specifically, a kind of method of dual controller storage extension cabinet cascade is claimed in the application, it is characterised in that the level
Linked method specifically includes following steps：
Since the connection all the way of dual controller storage extension cabinet cascade storing main cabinet, then from the close-by examples to those far off connection extension
Cabinet；The connection of another road extension cabinet then draws near connection extension cabinet from opposite direction, so that redundant link is formed, when wherein one
During bar link failure, extension cabinet can normally be accessed by redundant link by storing main cabinet, ensure that front-end business is normally run.
The method of dual controller storage extension cabinet cascade as described above, is further characterized in that, every extension cabinet can be
Two physical disks are connected in series together one by one.
The method of dual controller storage extension cabinet cascade as described above, is further characterized in that, extension cabinet includes IN and OUT
Mouthful, main cabinet only has two IN mouthfuls.
Brief description of the drawings
Fig. 1, dual controller storage extension cabinet cascade schematic diagram
Embodiment
Embodiment of the present invention is done below in conjunction with accompanying drawing 1 and is further described in detail：
The cascade schematic diagram that extension cabinet cabinet is connected for SAS ECP Extended Capabilities Ports shown in accompanying drawing 1.Storage device is divided into storage master
Cabinet (topmost one, accompanying drawing 1) and JBOD, main cabinet only need to external JBOD, there was only IN mouthfuls as the interface on the main cabinet of head node,
JBOD needs many cascades, as intermediate node, there is IN mouthfuls and OUT port.Since extension cabinet connection should be storing main cabinet, Ran Houyou
Proximal and distal connection extension cabinet.The connection of another road extension cabinet then draws near connection extension cabinet from opposite direction, forms redundancy chain
Road, when a wherein link failure, extension cabinet can normally be accessed by redundant link by storing main cabinet, ensure front-end business just
Often operation.
Specific extension cabinet connection method is as follows：
Dual controller extension cabinet is connected, and extension cabinet includes IN and OUT port, and main cabinet only has IN mouthfuls.
1) RAID system top left side SAS extend mouth enter->SAS extensions mouth goes out at the top of First extension cabinet
2) RAID system top right side SAS extend mouth enter->SAS extensions mouth goes out at the top of second extension cabinet
3) at the top of First extension cabinet SAS extensions mouth enter->SAS extensions mouth goes out at the top of 3rd extension cabinet
4) at the top of second extension cabinet SAS extensions mouth enter->SAS extensions mouth goes out at the top of 4th extension cabinet
5) second from the bottom extension cabinet bottom SAS extension mouth go out->The left SAS extensions mouth in RAID system bottom enters
6) last extension cabinet bottom SAS extend mouth go out->RAID system bottom, right SAS extension mouths enter
It should be evident that the only some embodiments of the present invention shown in accompanying drawing, for ordinary skill people
For member, on the premise of not paying creative work, other technical schemes can also be obtained according to these accompanying drawings, are belonged to
The scope of protection of the invention.
Technical solutions according to the invention method simple possible and obvious technical effects, can be applied wide in practice
It is general.
