Abstract
The utility model discloses a multi-path read-write system which comprises an original storage array, a first storage gateway, a second storage gateway and an application server. The first storage gateway is connected with the original storage array through optical fibers, the first storage gateway is connected on the second storage gateway through optical fibers, the application server is connected with the first storage gateway, the second storage gateway and the original storage array respectively through optical fibers, a multi-path driving module and a virtual volume set are arranged on the application server, and optical fiber cards are arranged on the original storage array, the first storage gateway, the second storage gateway and the application server. According to the multi-path read-write system, the original storage array is added based on an original basic system. Even though downtime occurs to the storage gateways, the original storage array can also map storage devices to the application server through a direct connection mode, and continuity of application and data of a user can be guaranteed under the situation.
Description
Technical field
The utility model relates to a kind of read-write system, particularly a kind of multipath read-write system.
Background technology
Multipath I/O technology (being Multipath I/O).It is a function of using a plurality of data routings to provide support for memory device.The multipath function is by providing from server or trooping and shift to improve the availability of storage resources to the path failure of storage subsystem.If server is initiated the program adapter by a plurality of fibre channel port or a plurality of iSCSI and visited logical unit number (LUN), must on this server, MPIO be installed.
But multipath read-write system before this, can't solve the path aggregation problem of storage gateway and original array, so selecting paths that can't be correct, can't guarantee the consistance of user data, so include only storage gateway, do not comprise the original storage array.Under this environment, owing to the path of the path of original array and storage gateway can't being condensed together, user's storage can only be mapped to application server by storage gateway, can the state quality of storage gateway just is directly connected to the user normally use this system, the machine in case storage gateway is delayed, user's application also just is forced to end the memory device on the application server and will loses, and then user's application is interrupted.
Technical scheme
For problems of the prior art, even the purpose of this utility model is to provide a kind of storage gateway machine of delaying, the memory device of application server still can be accessed, guarantees user's the impregnable multipath read-write system of front end applications.
in order to achieve the above object, the utility model is by the following technical solutions: a kind of multipath read-write system, comprise the original storage array, the first storage gateway, the second storage gateway and application server, described the first storage gateway is connected with the original storage array by optical fiber, described the first storage gateway is connected on the second storage gateway by optical fiber, described application server by optical fiber respectively with the first storage gateway, the second storage gateway is connected with the original storage array, described application server is provided with multipath driver module and virtual volume group, described original storage array, the first storage gateway, on the second storage gateway and application server, sonet card is installed.On described the second storage gateway, by optical fiber, be connected with storage array.
Adopt technique scheme, the utlity model has following beneficial effect: on the original base system, increased the original storage array.The machine even storage gateway is delayed, original storage array also can shine upon memory device to application server by direct-connected mode, guaranteed the continuity of user's application in this case and data.
The accompanying drawing explanation
Fig. 1 is the structural representation of a kind of multipath read-write system of the utility model.
Embodiment
The utility model is further explained below in conjunction with Figure of description and specific embodiment.
As shown in Figure 1, a kind of multipath read-write system, comprise original storage array, the first storage gateway, the second storage gateway and application server, described the first storage gateway is connected with the original storage array by optical fiber, and described original storage array has disk array be used to storing user data for user's data center.
Described the first storage gateway is connected on the second storage gateway by optical fiber, and after using storage gateway, the space availability ratio of user array and readwrite performance can be significantly increased.Utilize two storage gateways, user's original array and new array are done to a high available backup, protection user's data real time backup.
Described application server is connected with the first storage gateway, the second storage gateway and original storage array respectively by optical fiber, described application server is provided with multipath driver module and virtual volume group, user's front end applications just operates on described virtual volume group, on described original storage array, the first storage gateway, the second storage gateway and application server, sonet card is installed, relevant sonet card is responsible for the transmission of data, and remaining sonet card is in waiting status.On described the second storage gateway, by optical fiber, be connected with storage array.
Claims (2)
1. multipath read-write system, comprise the original storage array, the first storage gateway, the second storage gateway and application server, it is characterized in that described the first storage gateway is connected with the original storage array by optical fiber, described the first storage gateway is connected on the second storage gateway by optical fiber, described application server by optical fiber respectively with the first storage gateway, the second storage gateway is connected with the original storage array, described application server is provided with multipath driver module and virtual volume group, described original storage array, the first storage gateway, on the second storage gateway and application server, sonet card is installed.
2. a kind of multipath read-write system according to claim 1, is characterized in that by optical fiber, being connected with storage array on described the second storage gateway.
