Description
Technical field
The present invention relates to field of cloud computer technology.More particularly, to a kind of de-centralized cluster storage system.
Background technology
Along with cloud computing and the fast development of big data, in order to provide high bandwidth, low latency data access to access and enable
Memory space is transparent extending transversely, is born and various cluster-based storage.Distinguish from framework, can generally be divided into
Centralized cluster-based storage (centralized distributed storage) and de-centralized cluster-based storage
(decentrialized distributed storage) two kinds.
Wherein, de-centralized cluster-based storage, owing to not having the central node concentrated, it is thus achieved that preferably autgmentability is with available
Property.
In prior art, de-centralized cluster storage system substantially can be divided into the following two kinds:
(1) the most unshared (share nothing) storage system.As it is shown in figure 1, in complete unshared storage system,
All of node is entirely without sharing, by interconnection technique, such as Ethernet and IB network distribution data between multiple nodes, often
Data between individual node or be duplicate relation, or ensure the available of data between each node by correcting and eleting codes technology
Property and reliability.At present the most business-like storage system, if EMC ISILON and ScaleIO is exactly this most unshared deposit
The Typical Representative of storage system；Increase income storage system, be also the generation of this complete unshared storage system such as CEPH and GlusterFS
Table.The benefit of this complete unshared storage system is that all of memory node is full symmetric, disposes more flexible.Its shortcoming
It is, for the industrial access protocal NFS/CIFS/iSCSI etc. of standard, in order to ensure the reliabilty and availability of data, to pass through
Intranet accesses non-entrance memory node and operates data redundancy, so can bring the more behaviour across interconnected
Make, thus bring the greater loss in delay.
(2) double controlled storage systems.As in figure 2 it is shown, this pair of controlled storage system includes multiple dual control unit, each is double
Control unit includes two controllers, and a disk group shared by two controllers of each dual control unit.Each dual control list
Two controllers of unit share a disk group of rear end, and two controls of each dual control unit by SAS or optical fiber
Between device by interconnected technology such as Ethernet or IB (Infiniband) network distribution data to this dual control unit after
The disk group of end.The reliability of data is by encoding the most various disk array between each hard disk in the disk group of rear end
(RAID-Redundant Arrays of Independent Disks) technology tolerates that limited disk is damaged, at limited disk
In the case of damage, data still can recover.The availability of data is ensured by dual controller, once a dual control
A controller in unit breaks down, another controller temporary takeover of this dual control unit the controller broken down
The data, services provided to user.Meanwhile, by the interconnected of controller, according to strategy, data are distributed to multiple dual control
Unit.The most business-like storage system at present, if NetAPP ONTAP GX and XtremeIO is this pair of controlled storage system
Typical Representative.Compared with complete unshared storage system, this pair of controlled storage system can reduce across a network as far as possible
Operation, data reliability is ensured by RAID technique, and availability is ensured by dual controller.Thus, double controlled storage systems can
To complete a data access service not across interconnected as far as possible.The shortcoming of this pair of controlled storage system is, in order to protect
The availability of card data, needs dual control unit extensions one by one when extending transversely, and cannot be as complete unshared storage system
System is the most extending transversely.Additionally, due to the ratio that two controllers share a disk group, controller and disk group can only
For 2:1.
