Description

融合式虛擬化存儲系統 Converged virtualized storage system

本發明涉及伺服器架構領域,特別是涉及一種融合式虛擬化存儲系統。 The present invention relates to the field of server architecture, and in particular, to a converged virtualized storage system.

在現有的企業使用者存儲解決方案中,參見圖1所示,傳統虛擬化存儲系統100是由多個儲存裝置110(其為JBOD,全稱Just a bunch of disks,或稱硬碟簇)、多個檔案伺服器120、多個虛擬伺服器130所構成的集群式三層架構,每一層架構之間是通過複雜的線纜(例如SAS線纜或光纖等)進行互聯,並且通過複雜的軟體層面的配置完成整個系統結構的拓撲配置。如圖1所示,每一該儲存裝置110(例如JBOD1、JBOD2、JBODn等)分別與每一該檔案伺服器120(例如檔案伺服器1、檔案伺服器2、檔案伺服器n等)相連,每一該檔案伺服器120與每一該虛擬伺服器130(例如虛擬伺服器1、虛擬伺服器2、虛擬伺服器n等)相連,每一該虛擬伺服器130與一交換機140相連,該交換機140分別與多個用戶端150(例如用戶端1、用戶端2、用戶端n等)相連。其中JBOD作為存儲領域中一重要的儲存裝置,也可以被稱為a spanned disk。JBOD並非具有前端邏輯以管理硬碟上的資料分佈,而是每一硬碟進行單獨定址,以作為獨立的存儲資源。該檔案伺服器120是一種具有分時系統檔管理功能,並且提供使用者訪問檔、目的的併發 控制和安全保密措施的網路服務器。該虛擬伺服器130通過軟硬體技術將其自身分成為若干個主機,每一被分成的主機具有獨立的功能變數名稱、IP位址,但是共用真實主機的CPU、RAM、作業系統以及應用程式,相對於使用者而言,所操作的伺服器與真實獨立的主機功能一樣。因此,用戶能夠通過用戶端150、交換機140、虛擬伺服器130和檔案伺服器120訪問儲存裝置110中的資料資訊。由於每一該儲存裝置110分別與每一該檔案伺服器120相連,每一該檔案伺服器120與每一該虛擬伺服器130相連,每一該虛擬伺服器130與一交換機140相連,因此使得整個傳統虛擬化存儲系統100具有較好的冗餘設計(或餘度設計,redundancy design)。但是如此的冗餘設計,使得傳統虛擬化存儲系統100存有以下缺陷:其一,虛擬伺服器130和檔案伺服器120之間錯綜複雜的網路線纜需要軟體配置拓撲,檔案伺服器120和儲存裝置110之間錯綜複雜的網路線纜也需要軟體配置拓撲;其二,若遇到擴容等情況時,複雜的線纜連接以及配置介面會使得擴容變得非常繁瑣而效率較低。 In the existing enterprise user storage solution, as shown in FIG. 1 , the traditional virtualized storage system 100 is composed of a plurality of storage devices 110 (which are JBOD, collectively called Just a bunch of disks, or hard disk clusters). The file server 120 and the plurality of virtual servers 130 form a clustered three-layer architecture, and each layer is interconnected by a complicated cable (such as a SAS cable or an optical fiber) and passes through a complex software layer. The configuration completes the topology configuration of the entire system structure. As shown in FIG. 1, each of the storage devices 110 (for example, JBOD1, JBOD2, JBODn, etc.) is respectively connected to each of the file servers 120 (for example, file server 1, file server 2, file server n, etc.). Each of the file servers 120 is connected to each of the virtual servers 130 (eg, virtual server 1, virtual server 2, virtual server n, etc.), and each of the virtual servers 130 is connected to a switch 140. The 140 is connected to a plurality of client terminals 150 (for example, client terminal 1, client terminal 2, client terminal n, etc.). JBOD, as an important storage device in the storage field, can also be called a spanned disk. JBOD does not have front-end logic to manage the distribution of data on the hard disk, but each hard disk is individually addressed as a separate storage resource. The file server 120 is a type of system management function with time-sharing system and provides concurrent access for users and files. A web server that controls and secures security measures. The virtual server 130 divides itself into a plurality of hosts through software and hardware technologies, and each divided host has an independent function variable name and an IP address, but shares the CPU, RAM, operating system, and application of the real host. Relative to the user, the server being operated has the same function as the real independent host. Therefore, the user can access the material information in the storage device 110 through the client 150, the switch 140, the virtual server 130, and the file server 120. Since each of the storage devices 110 is connected to each of the file servers 120, each of the file servers 120 is connected to each of the virtual servers 130, and each of the virtual servers 130 is connected to a switch 140, thus The entire traditional virtualized storage system 100 has a better redundancy design (or redundancy design). However, such a redundant design causes the conventional virtualized storage system 100 to have the following drawbacks: First, the intricate network cable between the virtual server 130 and the file server 120 requires a software configuration topology, the file server 120 and the storage device. Intricate network cables between 110s also require a software configuration topology. Second, in the case of capacity expansion, complex cable connections and configuration interfaces can make the expansion very cumbersome and inefficient.

有鑑於此,極需提供一種新的融合式虛擬化存儲系統以解決上述問題。 In view of this, it is highly desirable to provide a new converged virtualized storage system to solve the above problems.

參見圖2所示,根據本發明的一目的,本發明提供一種融合式虛擬化存儲子系統200,且設置在一伺服器(例如4U的集群伺服器)中, 該融合式虛擬化存儲子系統200至少包括:第一伺服器節點210、第二伺服器節點220、存儲空間單元240以及共用存儲池230。在本發明的其他實施例中,該第一伺服器節點與該第二伺服器節點可以為多個。 Referring to FIG. 2, according to an object of the present invention, the present invention provides a converged virtualized storage subsystem 200, and is disposed in a server (for example, a 4U cluster server). The converged virtualized storage subsystem 200 includes at least a first server node 210, a second server node 220, a storage space unit 240, and a shared storage pool 230. In other embodiments of the present invention, the first server node and the second server node may be multiple.

如圖2所示,該第一伺服器節點210和第二伺服器節點220互為冗餘(redundancy)配置。亦即,該第一伺服器節點210和第二伺服器節點220中任一伺服器節點可以作為另一伺服器節點的備用。通過上述冗餘配置可以減少或避免因單個伺服器節點的故障而使該融合式虛擬化存儲子系統200不能正常運行的情況發生。尤其針對用於製造、醫療、零售等領域的存儲系統而言,資料可用性和安全性對於不間斷操作顯得極其重要。上述融合式虛擬化存儲子系統200安裝有一作業系統(圖中未示),該作業系統內定義一存儲空間單元240。該第一伺服器節點210和該第二伺服器節點220分別通過該存儲空間單元240訪問該共用存儲池230中的至少一硬碟簇310,以實現該第一伺服器節點210和該第二伺服器節點220的同步,進而保證冗餘存儲的配置。該作業系統內至少包括一虛擬伺服器211和一檔案伺服器212。該檔案伺服器212可以分別配置該第一伺服器節點210與該第二伺服器節點220,該虛擬伺服器211也可以分別配置該第一伺服器節點210與該第二伺服器節點220,具體參見圖2所示。該虛擬伺服器211(例如圖2中的虛擬伺服器1、虛擬伺服器2)是藉由該作業系統的的應用程式堆疊方式與該檔案伺服器212(例如圖2中的檔案伺服器1、檔案伺服器2)對應相連,以實現該虛擬伺服器211與該檔案伺服器212的快捷匹配。相較于現有技術通過網路線纜的連接以及相關軟體的配置拓撲,本發明通過應用程式的堆疊有助於存儲系統的執行效能,而無需花費太多系統執行時間,從而解決虛擬 伺服器211訪問檔案伺服器212的延遲和複雜的匹配問題。設置在該虛擬伺服器211內的多個主機系統(圖中未示)通過一虛擬層(圖中未示)能夠實現協同工作、統一管理和不間斷的維護,其中多個主機系統可以運行相同/不同的作業系統,該虛擬層起到抽象層作用,使物理硬體從和應用程式相關聯的作業系統去耦合,以實現更大的資源利用和靈活性。虛擬層允許具有同質或異質作業系統的虛擬機器或客戶機單獨地但並行地在相同或不同的物理機上運行。由於該虛擬伺服器211和該檔案伺服器212形成的伺服器節點210、220屬於同一層的扁平化架構,因此能夠簡化現有虛擬伺服器和檔案伺服器之間的線纜(例如SAS線纜或光纖)管理,即僅需一簡單配置即能夠實現通過多個不同的主機系統訪問該檔案伺服器212,而無需物理連接至該檔案伺服器212。此外,扁平化架構能夠提供強大的擴展能力,因此能夠容易地實施在該融合式虛擬化存儲子系統200中增加(或稱擴展)虛擬伺服器211或檔案伺服器212,進而大幅加強整個系統的可靠性和可維護性。 As shown in FIG. 2, the first server node 210 and the second server node 220 are mutually redundant configuration. That is, any one of the first server node 210 and the second server node 220 can serve as a backup for another server node. The redundant configuration described above can reduce or avoid the occurrence of failure of the converged virtualized storage subsystem 200 due to a single server node failure. Especially for storage systems used in manufacturing, medical, retail and other fields, data availability and security are extremely important for uninterrupted operation. The above-described converged virtualized storage subsystem 200 is provided with an operating system (not shown) in which a storage space unit 240 is defined. The first server node 210 and the second server node 220 respectively access the at least one hard disk cluster 310 in the shared storage pool 230 through the storage space unit 240 to implement the first server node 210 and the second The synchronization of the server node 220, thereby ensuring the configuration of redundant storage. The operating system includes at least a virtual server 211 and a file server 212. The file server 212 can be configured with the first server node 210 and the second server node 220, respectively. The virtual server 211 can also configure the first server node 210 and the second server node 220 respectively. See Figure 2. The virtual server 211 (for example, the virtual server 1 and the virtual server 2 in FIG. 2) is connected to the file server 212 by the application stacking method of the operating system (for example, the file server 1 in FIG. 2). The file server 2) is connected to achieve a quick match between the virtual server 211 and the file server 212. Compared with the prior art, through the connection of the network cable and the configuration topology of the related software, the present invention helps the performance of the storage system by stacking the application without spending too much system execution time, thereby solving the virtual The server 211 accesses the latency and complex matching issues of the file server 212. A plurality of host systems (not shown) disposed in the virtual server 211 can achieve coordinated work, unified management, and uninterrupted maintenance through a virtual layer (not shown), wherein multiple host systems can run the same / Different operating systems, the virtual layer acts as an abstraction layer that decouples the physical hardware from the application system associated with the application for greater resource utilization and flexibility. The virtual layer allows virtual machines or clients with homogeneous or heterogeneous operating systems to run on the same or different physical machines individually but in parallel. Since the server nodes 210, 220 formed by the virtual server 211 and the file server 212 belong to the same layer of flat architecture, the cable between the existing virtual server and the file server can be simplified (for example, a SAS cable or Fiber optic) management, that is, a single configuration is required to access the file server 212 through a plurality of different host systems without physically connecting to the file server 212. In addition, the flattening architecture can provide powerful scalability, so that it is easy to implement adding (or expanding) the virtual server 211 or the file server 212 in the converged virtualized storage subsystem 200, thereby greatly enhancing the entire system. Reliability and maintainability.

The first storage expansion module 241 and the second storage expansion module 242 are configured to transfer commands and data sent by the controller 250 to a hard disk drive 231 (such as a SAS drive or a SATA drive) of a hard disk cluster 310.

進一步參見圖3A及3B,該共用存儲池230的該硬碟簇310還包括第一IO模組331和第二IO模組332,第一IO模組331和第二IO模組332均包括一擴展器320(expanders),每一該擴展器320均與多個硬碟驅動器231相連,同時兩個該擴展器320分別藉由其對應的第一存儲擴展模組241與第一伺服器節點210的控制器250相連,以及藉由其對應的第二存儲擴展模組242與第二伺服器節點220的控制器250相連。該擴展器320可以採用三種路由方式:直接路由方式(direct routing)、路由表方式(routing table)以及 刪減路由方式(subtractive routing)以實現該控制器250、存儲擴展模組、擴展器320及該硬碟驅動器231之間的彼此路由。該擴展器320為可選組件。在本發明的其他實施中,該第一存儲擴展模組241及第二存儲擴展模組242可以直接連接至硬碟驅動器231。 Referring to FIG. 3A and FIG. 3B, the hard disk cluster 310 of the shared storage pool 230 further includes a first IO module 331 and a second IO module 332. The first IO module 331 and the second IO module 332 each include a Expanders 320 (expanders), each of the expanders 320 are connected to the plurality of hard disk drives 231, and the two expanders 320 are respectively connected to the first server node 210 by their corresponding first storage expansion modules 241 and 210 The controller 250 is connected and connected to the controller 250 of the second server node 220 by its corresponding second storage expansion module 242. The expander 320 can adopt three routing modes: direct routing, routing table, and Subtractive routing is performed to implement mutual routing between the controller 250, the storage expansion module, the expander 320, and the hard disk drive 231. The expander 320 is an optional component. In other implementations of the present invention, the first storage expansion module 241 and the second storage expansion module 242 may be directly connected to the hard disk drive 231.

在本發明的實施例中,如圖3A及3B所示的該第一伺服器節點210的至少一控制器250和第二伺服器節點220的至少一控制器250利用雙域SAS(Dual Domain SAS(SAS為Serial Attached SCSI的簡稱))技術,利用存儲空間單元240的第一存儲擴展模組241和第二存儲擴展模組242實現同時訪問同一硬碟驅動器231。在其他實施例中,該控制器250可以被替換為主匯流排適配器(Host Bus Adapter,簡稱HBA),其也能夠利用雙域SAS技術同時訪問同一硬碟驅動器231。由於該融合式虛擬化存儲子系統200通過採用雙域SAS技術以實現冗餘配置,因此能夠容許主匯流排適配器的故障、外部線纜(external cable)故障、擴展器(expanders)故障以及硬碟簇(JBOD)的故障,這是極其重要的。該雙域SAS技術不同與現有技術的雙路徑SATA(即Dual Path SATA)技術方案,後者僅使用單個域的方式以容許線纜的故障發生,而前者卻能夠提供完整的冗餘的雙域SAS。另外,相較於雙路徑SATA,雙域SAS能夠提供更高的可靠性、更高的性能以及資料可用性。需注意的是,雙域SAS與雙路徑SATA的主要區別在於是使用SAS驅動器,還是使用SATA驅動器。由於雙口型硬碟驅動器能夠在一個雙域SAS內提供完整途徑的冗餘配置,而SAS驅動器為雙口型硬碟驅動器,因此,在雙域SAS內應該採用SAS驅動器。在本發明的實施例中,該硬碟驅動器231為SAS驅動器,SAS驅動器具有雙口(Dual Ports)滿足上述條件。 In an embodiment of the present invention, at least one controller 250 of the first server node 210 and at least one controller 250 of the second server node 220 as shown in FIGS. 3A and 3B utilize dual domain SAS (Dual Domain SAS) (SAS is short for Serial Attached SCSI) technology, the first storage expansion module 241 and the second storage expansion module 242 of the storage space unit 240 are used to simultaneously access the same hard disk drive 231. In other embodiments, the controller 250 can be replaced with a Host Bus Adapter (HBA), which can also access the same hard disk drive 231 simultaneously using dual domain SAS technology. Since the converged virtualized storage subsystem 200 implements redundant configuration by employing dual domain SAS technology, it can tolerate failure of the main bus adapter, external cable failure, expanders failure, and hard disk. Cluster (JBOD) failure, this is extremely important. The dual-domain SAS technology differs from the prior art dual-path SATA (Dual Path SATA) technology solution, which uses only a single domain to allow cable failures, while the former provides complete redundant dual-domain SAS. . In addition, dual-domain SAS provides higher reliability, higher performance, and data availability than dual-path SATA. It is important to note that the main difference between dual-domain SAS and dual-path SATA is whether to use a SAS drive or a SATA drive. Since the dual-port hard disk drive provides a full-range redundant configuration in a dual-domain SAS, and the SAS drive is a dual-port hard disk drive, a SAS drive should be used in the dual-domain SAS. In the embodiment of the present invention, the hard disk drive 231 is a SAS drive, and the SAS drive has dual ports (Dual Ports) satisfying the above conditions.

當該硬碟驅動器231為雙口型硬碟驅動器且第一IO模組331與第二IO模組332互為冗餘配置時,使得該雙域SAS滿足冗餘設計的條件。因此,在本實施例中的雙域SAS能夠容許雙口型硬碟驅動器的其中一個埠發生故障,或者容許該第一IO模組331和第二IO模組332中的任一IO模組發生故障,或者容許支援雙域SAS的控制器250的雙埠中的一個埠發生故障,或者容許外部線纜發生故障,但不影響整個該融合式虛擬化存儲子系統200的正常工作。 When the hard disk drive 231 is a dual-port hard disk drive and the first IO module 331 and the second IO module 332 are redundantly configured with each other, the dual domain SAS is made to satisfy the condition of redundant design. Therefore, the dual-domain SAS in this embodiment can allow one of the two-port type hard disk drive to fail, or allow any one of the first IO module 331 and the second IO module 332 to occur. The failure, or one of the switches of the controller 250 that supports the dual domain SAS, fails, or allows the external cable to fail, but does not affect the normal operation of the entire virtualized storage subsystem 200.

另外,圖3A及3B的該第一伺服器節點210的至少一控制器250和第二伺服器節點220的至少一控制器250可以使用SSP協定並且通過存儲擴展模組(即第一存儲擴展模組241、第二存儲擴展模組242)和擴展器320與屬於SAS驅動器的硬碟驅動器231相連。當然,該控制器250也可以使用STP協定並且通過存儲擴展模組和擴展器320與屬於SATA驅動器的硬碟驅動器231相連。在本發明的實施例中,該控制器250是使用SSP協定並且通過存儲擴展模組和擴展器320與屬於SAS驅動器的硬碟驅動器231相連。 In addition, at least one controller 250 of the first server node 210 and at least one controller 250 of the second server node 220 of FIGS. 3A and 3B may use an SSP protocol and pass through a storage expansion module (ie, a first storage expansion module). The group 241, the second storage expansion module 242) and the expander 320 are connected to a hard disk drive 231 belonging to the SAS drive. Of course, the controller 250 can also be connected to the hard disk drive 231 belonging to the SATA drive through the storage expansion module and expander 320 using the STP protocol. In an embodiment of the invention, the controller 250 is coupled to a hard disk drive 231 belonging to the SAS drive by a storage expansion module and expander 320 using an SSP protocol.
