具体实施方式
参照相关附图中所描述的内容将详细揭示本发明优选实施例的内容。
目前许多市售的分层存储机制可能基于以下几种:1)每字节存储空间的费用;2)数据访问模式;3)低频率访问的数据迁移和布局至低级存储设备;然而,目前市售的存储分层机制致力于与用户日常基础访问的数据有关的质量方面。另外,这些目前市售的存储分层机制没有可配置的服务质量(QoS)参数(注:服务质量也可以简写为(QoS))可用以基于应用进程和用户数据设置用于触发分层/迁移进程的数据访问等待时间阈值。
本发明示例性实施例所述的系统和方法,诸如此处公开的那些,允许在每一用户基础和/或每一应用进程基础上设置的可配置的应用数据等待时间阈值,以便存储分层机制(例如存储迁移机制)被触发用以移动应用数据到不同级存储器中。此外,本发明披露的系统和方法可以进一步提供以下特点:1)促进与通过存储子系统托管的应用进程相关的QoS水平的显著提高;2)与存储访问相关的可预测等待时间;3)可协调性,用于确保提供最高QoS的存储资源的完全利用,从而在性能层提供充分的投资回报率(ROI);4)用于提高商业紧要和/或时间紧要应用进程需求的QoS的紧急手控管理;5)基于QoS阈值自动退出较低执行的存储;6)基于QoS阈值自动迁移用户和应用数据到不同的存储层;7)维持共享存储上可预测应用进程性能的重要改善;8)显著改善与应用进程特定数据访问相关的等待时间;9)基于策略自动分层和迁移,而无需人工干预;10)根据历史应用进程预先建模合预测以建议需要的高性能层和低性能层的容量。此外,本发明实施例所述的系统和方法,例如本文披露的,可以涉及由管理员改变企业级,配置每个用户和每个应用进程基础的QoS参数。在进一步的实施例中,所述的系统和方法根据服务质量在用户级或应用数据级水平上的应用进程概念,提供自发的存储分层和迁移。
参考图1A、图1B以及图3A至图3C,一个存储系统100,在这个存储系统上/中可以实施本发明的示例实施例所述的用于提供基于服务质量(QoS)的存储分层和迁移的方法。在示例实施例中,存储系统100可以包括处理器102。在另一实施例中,存储系统100还可以包括存储器104(例如随机存取存储器(RAM))。在又一实施例中,存储系统100还可以包括总线106。例如,所述处理器102和所述存储器104可以连接至所述总线106。本发明当前的实施例中,存储系统100还包括存储子系统,所述存储子系统还可以包括多个存储层,诸如,第一存储层108和第二存储层112。每个存储层可以包括一个或多个存储设备,这些存储设备构成存储池(例如,基卷108)。而且,第一存储层可以与第二存储层属于不同的存储级,这两个存储层通过属于第一存储层的存储设备的性能与属于第二存储层的存储设备的性能的比较来进行区分(例如,一个层的存储设备性能可能比另一个层的存储设备的性能高)。在进一步的实施例中,存储系统100的存储子系统可以通过总线106连接处理器102和存储器104。在本发明的再一个实施例中,存储系统100可以被配置(例如,通过在控制处理器102上执行的控制编程)用以允许提供基于QoS的存储分层和迁移方法通过和/或在存储系统100中执行,将在下文陈述。
参考图4,所示的流程图说明了本发明示例实施例所述的一种提供存储系统中基于服务质量的存储分层和迁移的方法。该方法400可以包括以下步骤:当应用进程访问存储系统的第一存储层时监控所述应用进程402。例如,在本发明实施例所述的存储系统100中,当一个或多个应用进程150正访问第一存储层(如图1A和1B所示)的一个存储池(例如,基卷108)时,所述一个或多个应用进程150的/对应的一个或多个QoS因子160可被监控(例如连续监控或采样)。在本发明实施例中,QoS因子160可以是与应用进程150相关联/有关系/对应的实时QoS因子。图1A说明了运行期间QoS因子160处于最佳水平时,多个应用进程150访问第一存储层的存储池108。监控(例如采样)可以实时进行以便只要应用进程150活动就保持监控窗口打开。在本发明当前实施例中,可以实时控制应用进程150的一些QoS因子160可以包括但不限于以下几种:读等待时间;写等待时间;存储介质反应时间;空闲时间(例如,当没有活动的读/写被执行的时间);数据遍及性(例如,被读和写的数据在存储子系统的存储设备中托管的应用共享内紧邻);数据定位(例如,与其他数据位置相比被访问的具体数据位置的度);数据年龄和应用文件年龄。
在另一个实施例中,该方法400可以进一步包括:基于所述的监控,确定应用进程的一QoS因子测量404。例如,当应用进程150d的(例如相关的)QoS因子160处于被监控时,确定所述QoS因子的读数和测量值。这些测量值(例如QoS因子测量值)可以在监控期间连续确定。一段时间后,与特定应用进程150相关的一个或多个QoS因子160可能会被破坏(如图1B所示通过标记“紧要QoS”),从而影响特定应用进程的总QoS阈值。本发明的示例实施例中,该方法400还包括以下步骤:比较所述QoS因子测量与以下至少一项:第一预先确定的QoS阈值(例如层阈值(TTH))和第二预先确定的QoS阈值(例如迁移阈值(MTH))406。当前实施例中,这些阈值可以用作存储系统100在等待时间方面的触发点。例如,基于实施例所述的比较,所述层阈值和迁移阈值可以用作触发点以触发存储系统100以执行以下系列步骤:a)存储分层;或b)将应用数据分别迁移到不同级的存储器,在以下详细描述中会有说明。图2所示图表(例如曲线图)说明了QoS因子的QoS水平/测量值(例如与应用数据相关的存储等待时间)对采样时间(如监控时间)绘制的图标。曲线图202的第一区域描述了当应用进程105运行在最佳QoS水平时的时间点。实线204表示实际无分层存储等待时间。虚线206表示预计的无分层存储等待时间。点线208表示应用数据被分层到不同级(例如,层)存储器后测量的实际等待时间。在采样段时间段(SP)内,QoS水平可被测量并与触发阈值(例如,层阈值(TTH)和迁移阈值(MTH))相比较。
在本发明实施例中,该方法400还包括:当所述比较表明所述QoS因子测量大于所述第一预先确定的QoS因子阈值时,创建一时间点(PiT)拷贝并设置所述PiT拷贝的访问许可为只读,其中所述PiT拷贝基于第一存储层408。例如,如图3A所示,当所述QoS因子测量与所述层阈值(TTH)的比较表明所述QoS因子测量大于所述TTH时,一个或多个PiT拷贝110可以基于所述第一存储层被创建(例如,可以离开基卷108被创建)。
本发明进一步实施例中,该方法400可以进一步:当所述比较表明QoS因子测量小于第一预先确定的QoS因子而大于第二预先确定的QoS因子时,从PiT拷贝迁移数据到第二存储层410。例如,如图3B所示,当QoS因子测量与层阈值(TTH)和迁移阈值(MTH)的比较表明QoS因子小于TTH而大于MTH时,数据会从一个或多个PiT拷贝(例如PiTs)110迁移到第二(例如下一个)存储层112。在迁移所述数据以提高当QoS因子测量在阈值之间快速波动时的情形中预防系统颠簸时,可以实施启发式方法。
在本发明的当前实施例中,该方法400可以进一步包括:在数据从所述PiT拷贝迁移到所述第二存储层完成后,设置创建第二存储层的访问许可为读和写并指引I/O命令到第二存储层412。例如,一旦所有数据从一个或多个PiT拷贝110已迁移到第二存储层412,引入的I/O命令可以被重新指引到第二存储层112并被第二存储层112应用,第二存储层112的访问许可被设置为读和写(R/W)以及PiT拷贝离开基卷108连续地被产生。
在本发明实施例中,该方法400可以进一步包括:当所述比较表明所述QoS因子测量小于所述第一预先确定的QoS因子阈值,并且小于所述第二预先确定的QoS因子阈值时,将第二存储层数据镜像到所述第一存储层414。例如,如图3C所示,当QoS因子测量与层阈值(TTH)和迁移阈值(MTH)的所述比较表明QoS因子小于TTH且小于MTH时,第二存储层112中的数据将被镜像到第一存储层108。在镜像所述的数据时可以实施启发式方法,以防止阈值间的系统颠簸。
在本发明的进一步实施例中,该方法400可以进一步包括:当所述第二存储层数据到所述第一存储层的数据的镜像是同步时,指引读命令到所述第二存储层416,并同步第一存储层和第二存储层之间的写命令418。例如,当镜像是同步时,所有读命令可以被第二存储层112应用,且所有写命令在基卷108与第二存储层112之间可以是同步的。
应该注意的是,根据本发明的所述实施例可以使用根据本说明书所教导的内容被编程的传统的通用数字计算机容易地实现,说明书中的内容对计算机领域的技术人员来说是显而易见的。基于当前公开的教导,适合的软件代码可以很容易地被熟练的编程员准备好,所述实现对软件领域的技术人员来说也是显而易见的。
应该理解本发明可以以软件包的形式来方便地实现。这样的软件包可以是利用计算机可读介质的计算机程序产品,该计算机可读介质包括储存的用于编程计算机以实现本发明已公开的功能和过程的计算机代码。所述计算机可读介质可以包括但不限于:任何类型的传统软盘、光盘、CD-ROM、磁盘、硬盘驱动器、磁光盘、ROM、RAM、EPROM、EEPROM、磁或光卡、或者其它任何合适用来存储电子指令的介质。
应该理解所述方法公开的步骤的特定顺序或层次是示例方法的例子。应当理解,基于设计偏好,所述方法中的步骤的特定顺序或层次可以重新排列,而仍在本发明的主题精神内。所附方法权利要求以样本顺序呈现了不同步骤的要素,并不必意味着仅限于所呈现的特定次序或层次。
应当相信,通过前述将理解本发明和许多其伴随的优点,显而易见,其组成的形式、结构和布置可以进行不同的变化,而不脱离本发明的范围和精神或不牺牲所有其物质优点。这里以前所述的形式只是示例说明,下列权利要求的目的是包含和包括此类变化。
