图 6本发明实施例提供的一种数据迁移触发装置结构示意图。 具体实施方式 为使本发明实施例的目的、 技术方案和优点更加清楚, 下面将结合本 发明实施例中的附图, 对本发明实施例中的技术方案进行清楚、 完整地描 述, 显然, 所描述的实施例是本发明一部分实施例, 而不是全部的实施例。 基于本发明中的实施例, 本领域普通技术人员在没有付出创造性劳动前提 下所获得的所有其他实施例, 都属于本发明保护的范围。
图 1 为本发明实施例提供的一种数据迁移触发方法流程图。 本发明实 施例的执行主体为与存储系统进行 10交互的主机。 如图 1所示, 包括: 步骤 11 : 主机接收用户设置的数据迁移策略; 数据迁移策略包括用户 设置的迁移对象、 迁移条件和迁移后的目标盘; 迁移对象包括 SAN存储系 统中的指定文件或指定目录或指定应用程序访问的数据。
本发明实施例的 SAN存储系统至少包括 10速度不相同的两类磁盘。 例如, SAN存储系统包括第一磁盘和第二磁盘, 第一磁盘的 10速度小于第 二磁盘的 10速度。 迁移对象迁移前所在的源盘为第一磁盘时, 相应地, 迁 移对象迁移后的目标盘为第二磁盘; 迁移对象迁移前所在的源盘为第二磁 盘时, 相应地, 迁移对象迁移后的目标磁盘为第一磁盘。 根据访问需求, 数据可在分级存储系统中磁盘阵列控制器的控制下在第一磁盘和第二硬盘 之间进行迁移。
为了使用户可控制被迁移的数据, 主机为用户提供了设置数据迁移策
略的人机接口。 用户可根据具体需求, 设置数据迁移策略, 包括设置需要 被迁移的数据即设置迁移对象、 设置在什么情况下对数据进行迁移即设置 迁移条件, 设置数据迁移后的目标盘。 例如, 用户希望立即提高访问指定 文件的 10速度, 可通过人机接口设置如下数据迁移策略: 迁移对象为 SAN 存储系统中指定文件或者指定目录, 迁移条件是立即迁移, 迁移后的目标 盘为第二硬盘。 又例如, 用户希望立即提高访问指定应用程序的 10速度, 可通过人机接口设置如下数据迁移策略: 迁移对象为 SAN存储系统中指定 应用程序, 迁移条件是立即迁移, 迁移后的目标盘为第二硬盘。 又例如, 用户希望立即降低指定文件的 10速度, 可通过人机接口设置如下数据迁移 策略: 迁移对象为 SAN存储系统中指定文件, 迁移条件是立即迁移, 迁移 后的目标盘为第一硬盘。 例如, 用户希望基于访问频率进行 10加速, 可通 过人机接口设置如下数据迁移策略: 迁移对象为 SAN存储系统中访问频率 达到指定频率的数据, 迁移条件是立即迁移, 迁移后的目标盘为第二硬盘。
步骤 12: 主机解析获取数据迁移策略中迁移对象的块地址。
主机接收用户设置的数据迁移策略后, 获取数据迁移策略中迁移对象 的块地址。 主机中安装的代理程序根据迁移对象的不同, 可通过主机文件 系统的接口、 操作系统接口或系统 10路径上特定驱动层等获取迁移对象的 块地址, 迁移对象的块地址可以是迁移对象的物理地址, 也可以是迁移对
Agent代理程序
步骤 13: 主机向 SAN存储系统中磁盘阵列控制器发送迁移指示, 指示 磁盘阵列控制器根据迁移条件和迁移对象的地址将迁移对象从源盘迁移到 目标盘。
获取迁移对象的地址后, 主机向磁盘控制器发送迁移指示, 迁移指示 中包括迁移对象的地址、 迁移条件和迁移后的目标盘, 用于指示磁盘阵列 控制器在迁移条件到达时, 根据迁移对象的地址将迁移对象从源磁盘迁移 到目标盘。 如果 SAN存储系统中对物理地址进行了映射, 而主机发送的迁 移对象的地址是逻辑地址, 由 SAN存储系统中磁盘阵列控制器将迁移对象 的逻辑地址转换为物理地址。 本发明实施例由主机根据用户设置的数据迁 移策略, 确定迁移对象的地址, 并向磁盘阵列控制器下发迁移指示, 而不
是由磁盘阵列控制器确定被迁移数据的块地址。
通过数据迁移策略中设置的目标盘, 可以将迁移对象迁移到 10速度较 快的目标盘, 也可将迁移对象迁移到 10速度较慢的目标盘, 因此不仅可以 满足用户提高访问迁移对象的 10速度的需求,也可降低访问迁移对象的 10 速度的需求。
本发明实施例提供的数据迁移触发方法, 主机接收到用户设置的数据 迁移策略后, 先获取数据迁移策略中迁移对象的块地址, 之后向 SAN存储 系统中的磁盘阵列控制器发送包括迁移对象的块地址的迁移指示, 指示磁 盘阵列控制器根据数据迁移策略中迁移条件和迁移方向, 将迁移对象从源 盘迁移到目标盘。 由于, 主机根据用户设置的数据迁移策略指示磁盘阵列 控制器进行数据迁移, 并解析迁移对象的块地址, 因而 SAN存储系统可达 到根据用户需求迁移指定数据的目的。
图 2A为本发明实施例提供的另一种数据迁移触发方法流程图。 图 2B 为本发明实施例提供的一种应用场景图。 本实施例主要说明用户希望瞬间 加速指定文件的 10速度时, 主机如何触发磁盘阵列控制器对该指定文件进 行数据迁移。如图 2B所示,本实施例中分级存储系统包括磁盘和固态硬盘, 磁盘和固态硬盘存储实际的文件, 而主机操作系统中文件为镜像文件。
如图 2A所示, 本实施例包括:
步骤 21a: 主机接收用户设置的数据迁移策略, 其中, 迁移对象为 SAN 存储系统中的指定文件, 迁移后的目标盘为固态硬盘, 迁移条件为立即迁 移。
用户可以在一项数据迁移策略中给出多个待迁移的指定文件。 其中, 指文件可以是目录文件, 也可以是单个文件。 用户设置上述数据迁移策略 的目的是, 对指定文件进行瞬间加速。
步骤 22a: 主机通过 Agent程序解析 SAN存储系统中指定文件的块地 址。
主机的 Agent程序通过文件系统的接口可探测出指定文件的块地址, 即指定文件对应数据块的地址, 指定文件的地址可以是逻辑地址, 也可以 是物理地址。
步骤 23a: 主机向 SAN存储系统中磁盘阵列控制器发送第一迁移指示,
指示磁盘阵列控制器根据指定文件的块地址立即将指定文件从磁盘迁移到 固态硬盘。
主机下发的第一迁移指示中包括指定文件的地址、 迁移条件和迁移后 的目标盘。 其中迁移条件为立即迁移, 迁移的目标盘为固态硬盘。 由于主 机端的文件系统中一般都含有文件碎片, 为了保证性能和效率, 主机可以 不需要将指定文件对应所有数据块的地址——对应下发给磁盘阵列控制 器, 而只需要将指定文件的大数据块的地址下发给磁盘阵列控制器, 对于 细小碎片的地址可不下发给磁盘阵列控制器。
如图 2B所示, 主机中 Agent程序获取 SAN存储系统中指定文件 Filel 的地址, 向 SAN存储系统中磁盘阵列控制器发送第一迁移指示, 磁盘阵列 控制器根据指示将指定文件 Filel 从磁盘迁移到固态硬盘。 指定文件 Filel 迁移前在磁盘中对应的数据块为 A, 经磁盘阵列控制器迁移到固态硬盘后, 在固态硬盘中对应的数据块为 B。
另外, 步骤 21a中迁移条件可以是指定时间内迁移。 如图 2C所示, 本 发明实施例提供的又一种数据迁移触发方法包括:
步骤 21b: 主机接收用户设置的数据迁移策略, 其中, 迁移对象为 SAN 存储系统中指定文件, 迁移后的目标盘为固态硬盘, 迁移条件为在指定时 间内迁移。
用户设置上述数据迁移策略的目的是, 在指定时间内对指定文件进行 力口速。
步骤 22 b: 主机通过 Agent程序获取 SAN存储系统中指定文件的块地 址。
步骤 23b:主机向 SAN存储系统中磁盘阵列控制器发送第二迁移指示, 指示磁盘阵列控制器在指定时间内, 根据指定文件的地址将指定文件从磁 盘迁移到固态硬盘。
第二迁移指示包括指定文件的地址、 迁移条件和迁移后的目标盘, 迁 移后的目标盘为固态硬盘, 迁移条件为在指定时间内迁移。 磁盘阵列控制 器接收到第二迁移指示后, 在指定时间内, 根据指定文件的地址将指定文 件从源盘迁移到目标盘。
本发明提供的数据迁移触发方法中, 用户设置的数据迁移策略中对指
定文件立即迁移到固态硬盘, 即对指定文件进行瞬间加速。 主机接收到用 户设置的上述数据迁移策略后, 通过文件作系统接口获取指定文件的地址 后, 向磁盘阵列控制器发送第一迁移指示, 指示磁盘阵列控制器立即根据 指定文件的地址将指定文件迁移到固态硬盘, 从而满足了用户瞬间提高主 机访问指定文件的 10速度的需求。 进一步, 也可以用户设置的在指定时间 内迁移的迁移条件, 向磁盘阵列控制器发送第二迁移指示, 指示磁盘阵列 控制器在指定时间内, 根据指定文件的地址将指定文件从源盘迁移到目标 盘,从而满足了用户在指定时间内提高主机访问指定文件的 10速度的需求。
图 3A为本发明实施例提供的再一种数据迁移触发方法流程图。 图 3B 为本发明实施例提供的图 3A的应用场景图。本实施例主要说明用户希望瞬 间加速指定应用程序访问的数据的 10速度时, 主机如何触发磁盘阵列控制 器对该指定应用程序访问的数据进行迁移。 如图 3B所示, 本实施例中分级 存储系统包括磁盘和固态硬盘。
如图 3A所示, 本实施例包括:
步骤 31 : 主机接收用户设置的数据迁移策略, 其中, 迁移对象为指定 应用程序在 SAN存储系统中访问的数据, 迁移条件为立即迁移, 迁移后的 目标盘为固态硬盘。
用户设置上述数据迁移策略的目的是, 对指定应用程序访问的数据进 行瞬间加速。
步骤 32: 主机安装的 Agent程序解析指定应用程序在 SAN存储系统中 访问的数据的块地址。
用户可以在一项数据迁移策略中给出一个指定应用程序或多个应用程 序。 主机通过操作系统的接口和系统 10路径上所插入的特定 10驱动层探 测出指定应用程序访问的数据的地址, 应用程序访问的数据的地址可以是 逻辑地址, 也可以是物理地址。
步骤 33:主机向磁盘阵列控制器发送包括 S AN存储系统中指定应用程 序访问的数据的地址第三迁移指示, 指示磁盘阵列控制器根据指定应用程 序访问的数据的地址立即将指定应用程序访问的数据从磁盘迁移到固态硬 盘。
如图 3B所示,主机中 Agent获取指定应用程序 Appl在 SAN存储系统
中访问的数据的地址后, 向存储系统中磁盘阵列控制器发送第三迁移指示, 磁盘阵列控制器根据指示将定应用程序 Appl访问的数据迁移固态硬盘。指 定应用程序 Appl访问的数据迁移前在磁盘中对应的数据块为 A, 经磁盘阵 列控制器, 在固态硬盘中对应的数据块为 B。
本发明提供的数据迁移触发方法中, 用户设置的数据迁移策略中对指 定应用程序访问的数据立即迁移到固态硬盘, 即对指定应用程序访问的数 据进行瞬间加速。 主机接收到用户设置的上述数据迁移策略后, 通过操作 系统接口获取指定应用程序访问的数据后, 向磁盘阵列控制器发送第二迁 移指示, 指示磁盘阵列控制器立即根据指定主机下发的应用程序访问的数 据地址, 将指定应用程序访问的数据迁移到固态硬盘, 从而满足了用户瞬 间提高指定应用程序访问的数据的 10速度的需求。
图 4 为本发明实施例提供的再一种数据迁移触发方法流程图。 本实施 例主要说明用户希望瞬间加速指定应用程序访问的数据中访问频率达到指 定频率的数据的 10速度时, 主机如何触发磁盘阵列控制器对 SAN存储系 统中数据进行迁移。 如图 4所示, 本实施例包括:
步骤 41 : 主机接收用户设置的数据迁移策略, 其中, 迁移对象为 SAN 存储系统中指定应用程序访问的数据中访问频率达到指定频率的数据, 迁 移条件为立即迁移, 迁移后的目标盘为固态硬盘。
用户设置上述数据迁移策略的目的是, 对指定应用程序在 SAN存储系 统中访问的数据中访问频率达到指定频率的数据进行瞬间加速。
步骤 42: 主机监测指定应用程序访问的数据, 并解析指定应用程序访 问的数据中访问频率达到指定频率的数据的块地址。
步骤 43: 主机向 SAN存储系统中磁盘阵列控制器发送第四迁移指示, 指示磁盘阵列控制器根据主机指示的地址立即将访问频率达到指定频率的 数据从磁盘迁移到固态硬盘。
主机指示的块地址为指定应用程序访问的数据中访问频率达到指定频 率的数据的块地址。 第四迁移指示包括指定应用程序访问的数据中访问频 率达到指定频率的数据的地址和迁移后的目标盘。 磁盘阵列控制器根据主 机指示的地址, 立即将指定应用程序访问的数据中访问频率达到指定频率 的数据从磁盘迁移到固态硬盘。
本发明提供的数据迁移触发方法中, 用户的数据迁移策略的目的是, 对指定应用程序访问的数据中访问频率达到指定频率的数据进行瞬间加 速。 主机对指定应用程序访问的数据中访问频率进行监测后, 向磁盘阵列 控制器下发第第四迁移指示, 磁盘阵列控制器根据主机指示的地址, 立即 将指定应用程序访问的数据中访问频率达到指定频率的数据从磁盘迁移到 固态硬盘, 从而满足了用户对指定应用程序访问的数据中访问频率达到指 定频率的数据进行瞬间加速的需求。
图 5 为本发明实施例提供的再一种数据迁移触发方法流程图。 本实施 例主要说明用户希望瞬间加速热点区域的 10速度时, 主机如何触发磁盘阵 列控制器对 SAN存储系统中数据进行迁移。 如图 5所示, 本实施例包括: 步骤 51 : 主机接收用户设置的数据迁移策略, 其中, 迁移对象为主机 下发的输入输出请求在 SAN存储系统中访问的数据区域中达到指定访问频 率的数据区域, 迁移条件为立即迁移, 迁移后的目标盘为固态硬盘。

步骤 53: 主机向 SAN存储系统中磁盘阵列控制器发送第五迁移指示, 指示磁盘阵列控制器根据主机指示的块地址立即将访问频率达到指定频率 的数据从磁盘迁移到固态硬盘。
第五迁移指示中包括主机监测到的热点数据区域的地址、 迁移后的目 标盘为固态硬盘, 迁移条件为立即迁移。 上述主机指示的块地址为达到指 定访问频率的数据区域的块地址。
