Description

先进电信计算架构***电源管理控制的方法和设备
技术领域
本发明涉及电信设备的电源管理技术， 特别涉及一种先进电信计算 架构 （ATCA ) ***电源管理控制的方法和设备。 发明背景
ATCA是 PCI工业计算机厂家协会（PICMG )组织制定并发展的开 放工业标准架构， 定位为通信设备和计算服务器通用的硬件平台技术， 通过基于 ATCA标准的各种模块， 可以构建满足各种需求的通信设备和 计算服务器设备。通常所说的 ATCA—般是指 PICMG 3.x系列标准规范， 制定了包括机框结构、 电源、 散热、 单板结构、 背板互连拓朴、 ***管 理及交换网建议等规范。 广义的 ATCA包括 PICMG组织制定的 ATCA、 ATCA300以及 MicroTCA等标准规范。
智能平台管理接口 （IPMI )是一些计算机通信的大公司为提高服务 器的可用性指标而推出的智能化平台管理接口标准， 目的是为服务器提 供设备管理、 传感器 /事件管理 、 用户管理、 风扇框 /电源框管理、 远程 维护等功能。
PICMG3.0规范将 IPMI规范定义为 ATCA遵循的管理规范， 利用
IPMI管理规范对单板电源进行管理控制的原理框图如图 1所示，其中智 能平台管理控制器（IPMC )和智能平台管理总线 （IPMB )都是 IPMI 规范中定义的管理组成部件。 电源转换 /控制模块负责接收背板电源输 入， 并且完成单板所需要的管理电源和负载电源的转换， 其中管理电源 提供给 IPMC等管理相关电路， 负载电源则提供给负载电路。 当单板插 入背板后， 电源转换 /控制模块不受控提供管理电源， IPMC上电， 开始 正常工作。但此时，并不提供负载电源，在满足一定的条件下，单板 IPMC 通过智能平台管理总线（IPMB )与机框管理单元（Shelf Manager )进行 通信， 在获得机框管理单元的允许后， 单板 IPMC使能电源转换 /控制模 块的负载电源使能信号， 电源转换 /控制模块才会提供负载电源， 供应给 负载电路。
ATCA的单板组成如图 2所示。 ATCA规范定义了两种类型的单板， 分别是前插板 ( FRB )和后插板（ RTM )。 ATCA单板的背板侧连接器分 3个区， 分别是 Zonel、 Zone2和 Zone3区， 其中 Zonel区连接器用于 提供前插板的电源和管理平面信号， Zone2 区连接器用于提供前插板控 制平面信号、 数据平面信号和时钟信号， Zone3 区连接器用于用户自定 义的连接。 前插板由机框前面*** ATCA机框， 通过 Zone 1区和 Zone2 区连接器与背板连接， 包括电源与信号的连接。 而后插板则由机框后面 *** ATCA机框， 通过 Zone3区连接器与对应的前插板连接， 包括电源 与信号的连接。
在图 2中， 前插板和后插板上都分别安装了两个扳手， 分别是上扳 手和下扳手， 应用于对单板进行插拔辅助。 其中， 前插板的下扳手位置 还安装了一个微动开关， 当下扳手打开或合上时， 微动开关将分别处于 不同的开关状态。 前插板上的 IPMC通过对连接到微动开关上的微动开 关信号的状态的检测， 可获知下扳手处于打开还是合上状态。 扳手的状 态变化是 ATCA单板的工作状态转换的关键要素之一。
ATCA单板在工作过程中分为不同的工作状态， 图 3是 ATCA单板 工作状态转换图。 如图 3所示， 当 ATCA单板没有完全*** ATCA机框 背板时， 单板处于 M0状态。 当单板完全***背板但没有合上扳手时， 单板处于 Ml状态， 此时已经向单板提供管理电源， 智能平台管理控制 器等管理相关电路正常上电并开始工作， 但并不提供负载电源， 单板处 于未激活状态。 在单板扳手合上后， 单板进入 M2状态， 智能平台管理 控制器通过微动开关信号检测到扳手合上， 开始向机框管理单元宣告单 板在位， 并向机框管理单元申请激活单板，在获得同意后进入 M3状态。 在 M3状态， 智能平台管理控制器开始与机框管理单元进行电源协商， 在获得机框管理单元的允许后，智能平台管理控制器控制电源转换 /控制 模块提供负载电源， 单板的其它部分正常上电， 单板被激活后， 进入
M4状态， 即单板正常工作的状态。 单板拔出的过程与***的过程相反， 在单板拔出过程中， 扳手的状态变化也是单板工作状态的变化的关键要 素之一。
在目前的 ATCA***中， 对后插板的电源供应框图如图 4所示。 后 插板电源由前插板电源转换 /控制模块提供的负载电源分路提供， 通过 Zone3 区连接器提供给后插板电路， 包括后插板管理电路和后插板负载 电路， 后插板的插拔和上电过程如下。
在进行单板热插拔的过程中， 需要避免出现大电流的突变， 而前插 板通过 Zone3区连接器提供给后插板的后插板电源的电流比较大，因此， 在***后插板的过程中， 必须保证断开后插板电源的供应。 其中一种方 法是先***后插板， 然后再***前插板； 另一种方法是先***前插板， 但扳手保持开的状态，这时候因为前插板的 IPMC没有检测到扳手合上， 会保持在 Ml状态， 电源转换 /控制模块不会提供负载电源， 所以也不会 有后插板电源供应。 在完成前插板和后插板的***和连接后， 再合上前 插板的扳手开关， 智能平台管理控制器通过智能平台管理总线开始与机 框管理单元进行通信。 在进行电源协商的过程中， 智能平台管理控制器 统一考虑前插板和后插板对电源供应的需求， 在获得机框管理单元的允 许后， 使能电源转换 /控制模块的负载电源使能信号， 允许电源转换 /控 制模块提供负载电源， 同时后插板也获得后插板电源的供应。 而后插板 拔出的过程中， 必须先打开前插板的扳手， 设备按照图 3中去激活的步 骤完成单板的去激活， 断开前插板负载电源供应同时也断开后插板电源 供应后， 才可以正常拔出后插板。
ATCA300 标准是 PICMG 组织在 ATCA 标准基础上制定的适合 300mm深机拒的电信硬件平台架构。 为了满足 300mm深机拒的安装需 求， ATCA300 标准中对前插板的尺寸进行了修改， 并且去掉了 ATCA 标准中的后插板 ( RTM ) ，而增加了与后插板（RTM )有类似应用的前 转换模块（ FTM ), ATCA300中前插板和前转换模块通过前插板的 Zone3 区与前转换模块的 Zone4区连接器及背板互连。 如图 5 中的 ATCA300 插板示意所示。
从图 5可以看到， 前转换模块除了在机框中的位置、 与前插板的连 接方式外， 与 ATCA中的后插板并没有很大的区别。 对前转换模块的电 源管理方法也与后插板的电源管理方法相同， 这里就不再赘述。 在本文 中， 通过后插板 /前转换模块来代表后插板或前转换模块， 以筒化说明方 式。
由上述可以看出，前插板的电源转换 /控制模块统一提供前插板负载 电源和后插板 /前转换模块电源供应， 不支持后插板 /前转换模块电源供 应的独立管理和控制，无法灵活地对后插板 /前转换模块电源供应进行管 理控制， 无法支持热插拔， 在后插板 /前转换模块插拔过程中必须断开前 插板负载电源的供应， 导致前插板工作的中断。
而且，后插板 /前转换模块电源供应需求一般由前插板根据的后插板 设计情况进行预先设定，因此不能根据所***的不同的后插板 /前转换模 块的实际功耗， 有效利用电源资源， 从而造成电源资源的浪费。 发明内容
本发明的实施例提供了一种 ATCA***电源管理控制的方法和一种 ATCA***，能够实现对 ATCA后插板 /前转换模块电源供应的独立管理 和控制。
一种先进电信计算架构 ATCA***， 包括： 前插板和后插板 /前转换 模块，所述前插板包括为所述前插板和后插板 /前转换模块提供电源的第 一电源转换 /控制模块， 所述***还包括：

根据所述控制信号将所述前插板提供的电源提供给所述后插板 /前 转换模块。
由上述技术方案可见， 在 ATCA***中，后插板 /前转换模块的电源 提供受控于控制信号， 在控制信号允许提供电源时， 才向后插板 /前转换 模块供电。 可见， 应用本发明实施例， 能够对后插板 /前转换模块的电源 的提供进行独立控制。 附图简要说明

本步骤中， 由于前插板的 IPMC事先并不知晓后插板对负载电源的 需求， 因此在本步骤， 双方进行负载电源需求的交互。
步骤 806, 前插板的 IPMC通过 IPMB总线与机框管理单元的机框 管理控制器进行电源需求协商。
本步骤中， 前插板的 IPMC根据与后插板的 MMC交互得到的后插 板负载电源需求数据， 与机框管理单元重新进行电源需求协商。
步骤 807, 机框管理单元的机框管理控制器允许该电源需求， 前插 板的 IPMC增加后插板负载电源的分配。
步骤 808, 前插板的 IPMC通过 IPMB总线通知 MMC允许为后插 板提供负载电源。
步骤 809, MMC使能负载电源使能信号， 并将其输出到后插板的电 源转换 /控制模块。
步骤 810, 电源转换 /控制模块提供负载电源， 后插板被激活， 并结 束本流程。
步骤 811 , MMC不使能负载电源使能信号。
步骤 812, 电源转换 /控制模块不提供负载电源， 后插板未被激活， 并结束本流程。
由上述方法流程可以看出，步骤 802 ~ 812即是图 6所示的方法总体 流程中步骤 620的细化操作。 在本实施例中， 根据微动开关的状态和与 IPMC的交互结果来确定是否允许后插板的电源转换 /控制模块提供负载 电源， 从而控制大的负载电流的输出。 并且， 当本实施例中后插板负载 电源的需求根据 IPMC和 MMC的协商确定时， 有利于提高机框电源资 源的利用效率。
事实上， 在实际应用中， MMC 也可以只根据微动开关的状态来确 定是否允许向后插板提供负载电源， 在这种情况下， 前插板在最初与机 框管理单元的电源协商时， 就必然包括了后插板的负载电源协商。 步骤 803 ~ 808的操作即可省略，在步骤 802中若接收到的信号要求激活后插 板， 则直接执行步骤 809 ~ 810即可。
本实施例中， 根据用户需求判断是否要求激活后插板的方式是通过 微动开关来感应用户需求的， 当然也可以通过其他的方式进行， 例如， 通过用户向前插板的 IPMC输入控制命令的方式， 要求激活后插板。 在 这种情况下， 步骤 803~808就可以省略了。
以上即为本实施例中提供的 ATCA***电源管理控制的方法流程。 本实施例还提供了实现 ATCA***的电源管理控制的设备， 可以用于实 施上述方法。
图 9即为本发明实施例一中 ATCA***的电源管理控制的设备结构 图。 如图 9所示， 该设备中包括前插板、后插板和机框管理单元。 其中， 前插板包括 IPMC、 电源转换 /控制模块、 微动开关、 负载电路和 Zone3 区连接器； 后插板包括模块管理控制器（MMC )、 电源转换 /控制模块、 微动开关、 后插板负载电路和 Zone3 区连接器。 后插板中的电源转换 / 控制模块即为图 7所示设备中第二电源转换 /控制模块 702的具体化， MMC和微动开关即构成图 7所示设备中控制电路 703。
在该设备中，前插板中的电源转换 /控制模块提供的负载电源分路后 形成后插板电源通过 Zone3区连接器提供给后插板。 该电源在进入后插 板后被分离为后插板管理电源和后插板负载电源。 其中， 后插板管理电 源不受控地供应给后插板 MMC等管理相关电路。 后插板负载电源通过 在后插板增加的电源转换 /控制模块后供应给后插板负载电路，该负载电 源的供应受 MMC的控制，控制信号是 MMC输出到后插板中电源转换 / 控制模块的负载电源使能信号。只有 MMC使能后插板中电源转换 /控制 模块的负载电源使能信号后， 后插板负载电路才会获得后插板负载电 源。 另外， MMC是否输出负载电源使能信号， 则是根据 MMC对连接 到微动开关上的微动开关信号的检测来控制的。 该微动开关可以加在后 插板上扳手或者下扳手的位置， 后插板中 MMC通过对微动开关信号的 检测， 可以获知扳手的开合状态， 根据该开合状态， 确定是否输出负载 电源使能信号。
在上述设备中， 还可以通过 IPMC 来辅助控制后插板中电源转换 / 控制模块中负载电源的提供， 即 MMC、 微动开关和 IPMC共同构成了 图 7所示***中的控制电路。 这种情况下， 即在后插板的工作状态转换 过程中， MMC通过 Zone3区连接器提供的 IPMB总线， 与前插板中的 IPMC进行通信， 根据通信的结果确定 MMC是否输出负载电源使能信 在上述设备实施方式中，后插板的管理电源是由前插板的电源转换 / 控制模块提供的负载电源分路得到的。 在实际应用中， 后插板的管理电 源也可以通过前插板的电源转换 /控制模块提供的管理电源分路得到，通 过 Zone3区连接器提供给后插板的 MMC。
在本实施例中提供的图 9所示的设备中， 用户需求信息是通过微动 开关的状态提供的， 当然也可以是通过用户向 IPMC输入控制命令的方 式提供。 这时， 图 7所示设备中的控制电路 703即由图 9所示的设备中 的 IPMC和 MMC构成。 由 IPMC将用户需求发送给 MMC, MMC再根 据用户需求控制后插板的电源转换 /控制模块中负载电源的提供。

3.如果最初前插板*** ATCA机框， 前插板智能管理控制器与机框 管理控制器协商电源需求时， 已经预分配了所***后插板的负载电源需 求， 则可以直接跳到步骤 4。 否则， 后插板上的模块管理控制器需要通 过 IPMB总线与前插板的智能平台管理控制器进行后插板负载电源需求 的交互。 前插板的智能平台管理控制器根据交互得到的后插板负载电源 需求数据， 通过 IPMB总线与机框管理控制器再次进行电源需求协商， 获得机框管理控制器的允许后， 增加后插板负载电源的分配。
4.在获得前插板智能平台管理控制器的允许后， 后插板模块管理控 制器使能后插板的电源转换 /控制模块的负载电源使能信号，后插板负载 电源正常提供， 后插板负载电路获得后插板负载电源供应， 后插板被激 活， 进入正常工作的 M4状态。

本步骤中， MMC根据用户需求判断是否要求激活后插板为： MMC 通过对连接到微动开关上的微动开关信号进行检测， 可以获知上扳手的 开合状态； 本实施例中， 当上扳手的状态为合时，表示要求激活后插板， 即希望为后插板的负载电路提供负载电源， 当上扳手的状态为开时， 表 示不要求激活后插板， 即不希望为后插板的负载电路提供负载电源。
步骤 1003, MMC通过 IPMB总线与前插板的 IPMC通信， 要求提 供后插板负载电源的供应。
步骤 1004, 前插板的 IPMC判断是否已经预分配了后插板的负载电 源需求， 若是， 则执行步骤 1008及其后续步骤， 否则执行 1005及其后 续步骤。
步骤 1005, 前插板的 IPMC与后插板的 MMC通过 IPMB总线进行 后插板负载电源需求的交互。
本步骤中， 由于前插板的 IPMC事先并不知晓后插板对负载电源的 需求， 因此在本步骤， 双方进行负载电源需求的交互。

本步骤中， 前插板的 IPMC根据与后插板的 MMC交互得到的后插 板负载电源需求数据， 与机框管理单元重新进行电源需求协商。
步骤 1007, 机框管理单元的机框管理控制器允许该电源需求， 前插 板的 IPMC增加插板负载电源的分配。
步骤 1008, 前插板的 IPMC使能负载电源使能信号， 并将其输出到 后插板负载电源转换 /控制模块。
本实施例中，控制电源转换 /控制模块提供负载电源的控制信号与实 施例一中的相同， 这里就不再赘述。
步骤 1009,后插板负载电源转换 /控制模块提供负载电源，后插板被 激活， 并结束本流程。
步骤 1010, 前插板的 IPMC不使能负载电源使能信号。
步骤 1011 ,后插板负载电源转换 /控制模块不提供负载电源，后插板 未被激活， 并结束本流程。
由上述方法流程可以看出，步骤 1002 ~ 1011即是图 6所示的方法总 体流程中步骤 620的细化操作。 在本实施例中， 根据上扳手的开合状态 和与 IPMC 的交互结果来确定是否允许后插板负载电源转换 /控制模块 提供负载电源， 从而控制大的负载电流的输出。 并且， 当本实施例中后 插板负载电源的需求根据 IPMC和 MMC的协商确定时， 有利于提高机 框电源资源的利用效率。
本实施例中，步骤 1002中根据用户需求判断是否要求激活后插板的 方式是通过微动开关来感应用户需求的， 当然也可以通过其他的方式进 行，例如，在步骤 1002中通过用户向前插板的 IPMC输入控制命令的方 式， 要求激活后插板。 在这种情况下， 步骤 1003~1007就可以省略了。
以上即为本实施例中提供的 ATCA ***的电源管理控制的方法流 程。 本实施例还提供了实现 ATCA***的电源管理控制的设备， 可以用 于实施上述方法。
图 11 即为本发明实施例二中 ATCA***的电源管理控制的设备结 构图。 如图 11 所示， 该设备中包括前插板、 后插板和机框管理单元。 其中， 前插板包括 IPMC、 电源转换 /控制模块、 微动开关、 负载电路、 Zone3区连接器和后插板负载电源转换 /控制模块； 后插板包括模块管理 控制器（MMC )、 微动开关、 后插板负载电路和 Zone3区连接器。 后插 板负载电源转换 /控制模块即为图 7所示设备中第二电源转换 /控制模块 702的具体化， IPMC、 MMC和微动开关即构成图 7所示设备中控制电 路 703。
在该设备中，前插板中的电源转换 /控制模块提供的负载电源分路后 形成后插板电源， 该后插板电源被分离为后插板负载电源和后插板管理 电源。 其中， 后插板管理电源通过 Zone3区连接器不受控地供应给后插 板 MMC等管理相关电路； 后插板负载电源通过在前插板增加的后插板 负载电源转换 /控制模块后供应给后插板负载电路，该负载电源的供应受
IPMC的控制， 控制信号是 IPMC输出到后插板负载电源转换 /控制模块 的负载电源使能信号。只有 IPMC使能后插板负载电源转换 /控制模块的 负载电源使能信号后，后插板负载电路才会获得后插板负载电源。另夕卜， IPMC是否输出负载电源使能信号， 则是根据 MMC对连接到微动开关 上的微动开关信号的检测来控制的。 该微动开关可以加在后插板上扳手 或者下扳手的位置， 后插板中 MMC通过对微动开关信号的检测， 可以 获知扳手的开合状态， 根据该开合状态， 通过 Zone3 区连接器提供的 IPMB总线， 与前插板中的 IPMC进行通信， 告知 IPMC是否输出负载 电源使能信号。
在上述设备实施方式中，后插板的管理电源是由前插板的电源转换 / 控制模块提供的负载电源分路得到的。 在实际应用中， 后插板的管理电 源也可以通过前插板的电源转换 /控制模块提供的管理电源分路得到，通 过 Zone3区连接器提供给后插板的 MMC。

步骤 1207, 前插板的 IPMC与后插板的 MMC通过 IPMB总线进行 后插板负载电源需求的交互。
本步骤中， 由于前插板的 IPMC事先并不知晓后插板对负载电源的 需求， 因此在本步骤， 双方进行负载电源需求的交互。
步骤 1208, 前插板的 IPMC通过 IPMB总线与机框管理单元的机框 管理控制器进行电源需求协商。

步骤 1214, 前插板的 IPMC不使能管理电源使能信号， 后插板电源 转换 /控制模块不提供管理电源， 后插板未***， 并结束本流程。
由上述方法流程可以看出，步骤 1203 ~ 1212即是图 6所示的方法总 体流程中步骤 620的细化操作。 在本实施例中， 根据上扳手的开合状态 和与 IPMC 的交互结果来确定是否允许后插板负载电源转换 /控制模块 提供负载电源， 从而控制大的负载电流的输出。 并且， 当本实施例中后 插板负载电源的需求根据 IPMC和 MMC的协商确定时， 有利于提高机 框电源资源的利用效率。

在上述***后插板的过程中， 步骤 2~3还可以为： 用户将请求激活 后插板的控制命令输入给 IPMC, IPMC通过 IPMB总线，与 MMC通信， 进行后插板工作状态管理相关的交互。 二： 在前插板和后插板都正常工作的情况下， 拔出后插板。
1.打开后插板的扳手， 后插板模块管理控制器通过 IPMB总线与前 插板智能平台管理控制器进行通信， 进行后插板工作状态管理相关的交 互， 要求拔出后插板。
2.前插板智能平台管理控制器通过后插板负载电源使能信号， 控制 后插板电源转换 /控制模块， 关断后插板负载电源供应， 后插板进入单板 未激活的 Ml状态。 如果有必要， 此时前插板的智能平台管理控制器可 以通过 IPMB总线与机框管理控制器进行电源需求的协商， 释放后插板 负载电源需求， 达到提高机框电源资源利用效率的目的。
3.拔出后插板， 对应槽位的前插板的智能平台管理控制器通过检测 在位信号的状态， 获知后插板的拔出。 前插板智能平台管理控制器通过 后插板管理电源使能信号，控制后插板电源转换 /控制模块关断后插板管 理电源的供应。
由上述可以看出， 本实施例在对负载电源供应控制方面与实施例二 中的方式相同， 同样可以实现对大电流的后插板负载电源受控提供的目 的， 支持前插板正常工作情况下后插板的热插板。 同时也能够支持后插 板负载电源需求的协商， 能够有效利用电源资源。 而与实施例二的区别 在于， 进一步增加了对后插板管理电源供应的控制， 更加提高了电源资 源的利用率和设备的安全性。
上述三个实施例均以后插板为例说明本发明在进行电源管理控制时 的方法和设备的具体实施方式。 对于 ATCA300标准中的前转换模块而 言， 上述电源管理控制方法和设备同样可以适用，从而实现对 ATCA300 的前转换模块的电源进行管理。
只要在 ATCA300 的前转换模块增加管理相关电路， 如微动开关、 MMC等， 并根据采用方案的不同， 在 ATCA300前转换模块或前插板增 加不同类型的电源转换 /控制模块， 如在 ATCA300前转换模块增加电源 转换 /控制模块， 或在前插板增加前转换模块负载电源转换 /控制模块， 或在前插板增加前转换模块电源转换 /控制模块， 并通过前插板的 Zone3 区连接器和前转换模块的 Zone4区连接器及它们间的背板， 提供原方案 中 ATCA前插板和后插板通过 Zone3区连接器连接的电源、管理和控制 信号， 就可以同样实现对 ATCA300前转换模块负载电源或前转换模块 管理电源的管理控制。
以上仅为本发明的较佳实施例而已， 并非用于限定本发明的保护范 围。 凡在本发明的精神和原则之内， 所作的任何修改、 等同替换、 改进 等， 均应包含在本发明的保护范围之内。
