Description

计算机设备与计算机设备的配置管理方法
本申请要求于2014年12月30日提交中国专利局、申请号为201410853336.2、发明名称为“计算机设备与计算机设备的配置管理方法”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及信息技术领域，特别涉及一种计算机设备和计算机设备的配置管理方法。
背景技术
随着数据中心和虚拟化技术的发展，数据网络可靠性通常依赖于网卡绑定技术，网卡绑定要求用户同时了解连接物理服务器的网络架构，这样才能设计出，符合数据中心可靠性的组网方案，增加了对系统维护人员的技能要求，同时也增加服务器维护难度，提高系统维护成本。为解决该问题，出现了通过服务器的管理软件来实现管理，通过管理软件，用户不再需要考虑网络组网可靠性，而是完全交给服务器的管理软件来完成，这样大大减少了用户维和护操作的复杂度，也降低了用户误操作或者由于网络配置错误导致的业务事故(例如广播风暴、业务中断等)。用户使用服务器的简化，实际上是增强了网卡和管理软件的功能，也导致管理软件和网卡的配置管理变得更加复杂。
无论是融合网卡，还是各种下一代多功能网卡，管理软件或者用户和网卡之间的配置管理通信变得越来越多(固件升级、物理功能配置、可靠性配置、虚拟机Qos配置、VLAN配置等)，网卡的可配置、可管理成为新一代服务器的一个重要功能。
为了实现服务器硬件即插即用，无状态计算成为现有服务器的必备特性，网卡、融合网络适配器(CNA，Converged Network Adaptor)，独立磁 盘阵列(RAID，Redundant Arrays of Independent Disks)卡、固态硬盘(SSD，Solid-state Drive)卡和图形处理器(GPU，Graphic Processing Unit)卡等高速外围组件互连(PCIE，Peripheral Component Interconnect Express)设备，都需要实现更换硬件但是配置不丢失功能。这些配置大都通过服务器管理软件以profile的形式存在，更换硬件或者新增硬件时，由系统管理模块SMM(System Management Module)下发所有外部设备的配置信息，达到硬件即插即用的目的。
现有技术中，SMM通过网络连接到Server设备上，通过两种方式实现对CNA/RAID/SSD等设备的配置和管理：
在Server系统上安装配置代理模块，SMM和配置代理模块通信，实现对CNA/RAID/SSD等设备的配置。
Server需要配置CNA/RAID/SSD等外部设备时，从SMM模块加载并启动一个简易的操作系统，配置完成后，再从Server本地启动业务系统。
通过在计算机设备的OS上安装配置代理工具的方式，依赖于客户选择的OS类型和版本，升级工具部署麻烦且无法控制，无法对固件版本进行检查，固件升级工具和OS系统类型强相关，开发工作量大；简易的操作系统增加系统启动时间，SMM需要通过网络连接Server主机系统，增加硬件成本，或者通过业务通道，管理和业务耦合，不利于维护和隔离。

附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动性的前提下，还可以根据这些附图获得其他的附图。

具体实施方式
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的一部分实施例，而不是全部实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动的前提下所获得的所有其他实施例，都应属于本发明保护的范围。
图1为本发明实施例一种计算机设备100的一种具体实现结构示意图。该计算机设备包括一个系统管理模块102(SMM，System Management Module)，一个PCIE Switch 101和一个中央处理器103(CPU，Centrol Processing Unit)，以及PCIE设备(以CAN、RAID和SSD的为例进行说明)。其中，SMM 102用于完成对该计算机设备的硬件管理，包括计算机设备的上下电控制、设备环境温度、单板电压监控、CNA/RAID/SSD等PCIE设备配置管理、Firmware固件升级等。SMM 102通过管理中央处理器MCPU(Management Central Process Unit)1021提供的PCIE端口连接计算机设备的PCIE Switch 101，PCIE Switch 101包含两个Up Port分别连接计算机设备的CPU 103和SMM 102的MCPU 1021，PCIE Switch 101有多个Down Port分别连接CNA/RAID/SSD等PCIE设备，计算机设备的CPU 103通过PCIE Switch访问CNA/RAID/SSD等外部设备。
根据PCIE的标准，PCIE网络属于树形结构，每个PCIE Switch在同一个时刻，只能有一个Up Port和多个Down Port。因此，图1中连接计算机设备CPU 103和SMM 102的MCPU 1021的两个Up Port，同时只能有一个Up Port在工作。正是通过在系统启动的不同阶段控制不同的Up Port与PCIE Switch101连接，使得SMM 102与PCIE Switch 101连接时，PCIE Switch 101断开与CPU 103的连接，在实现PCIE设备管理时，不依赖于计算机设备CPU 103的参与，节省了CPU 103的资源，不需要计算机设备的操作系统的参与，实现了SMM 102对PCIE设备(例如CNA/RAID/SSD等)的有效管理。同时，CNA等PCIE设备通过Down Port与PCIE Switch 101相连，不需要配置特殊的接口与SMM 102相连，简化了系统的配置。所述SMM 102通过不同的设备驱动 可实现对不同设备进行配置管理。
本发明实施例中，SMM 102通过不同的设备驱动可实现对不同设备进行配置管理，包括但不限于PCIE驱动、设备驱动和设备管理等。其中，PCIE驱动为基本的PCIE设备发现、地址空间分配等基本设备信息配置；设备驱动为各种PCIE设备专用驱动，主要满足设备管理模块对外部设备的配置管理功能；设备管理，是根据用户提供配置模板信息，完成对PCIE设备的参数配置。需要说明的是，上述SMM 102的配置管理完成后，需要重新启动计算机设备，以完成对PCIE设备的配置。
实现SMM模块中MCPU对PCIE设备进行配置管理，以及CPU正常使用PCIE设备的系统启动流程，如图2所示，包括：
步骤201：计算机系统上电；
步骤202：启动SMM；
步骤203：SMM配置PCIE Switch的上行端口为连接MCPU的端口；
步骤204：SMM对PCIE Switch下的PCIE设备进行枚举和配置；
例如可以采用PCIE标准定义的深度优先扫描算法，逐步发现PCIE Switch下挂接的所有PCIE设备，发现之后，需要配置基本的信息，例如，IO空间、内存空间等。
步骤205：SMM对PCIE Switch下的PCIE设备进行配置管理；
SMM对PCIE Switch下的PCIE设备进行配置管理包括但不限于升级fireware、配置参数(例如物理功能的个数、类型、带宽，RAID算法等)、查询PCIE设备信息等。
步骤206：配置PCIE Switch的上行端口为连接CPU的PCIE端口；
具体的，可以通过SMM模块和PCIE Switch之间的管理通道，例如mChannel管理通道，修改上行端口为连接计算机设备CPU的PCIE端口。其中，本发明实施例中的mChannel管理通道可以是两线式串行总线(I2C，Inter－Integrated Circuit)通道。
步骤207：PCIE Switch的上行端口切换到与CPU之间的PCIE端口时，所述计算机设备的CPU上电；
步骤208：计算机设备启动。
计算机设备的启动包括硬件初始化、操作系统的运行、应用程序的运行等。
上述图1的实现方式中，PCIE Switch与CPU是相互独立的，PCIE Switch在CPU的外部，PCIE Switch通过上行端口与CPU建立连接。在具体实现中，PCIE Switch也可以位于CPU中，PCIE Switch作为CPU内部集成的一个单元，该单元用于完成图1中PCIE Switch要完成的功能。如图3所示，图3为本发明实施例一种计算机设备的另一种具体实现结构示意图。该具体实现结构中，SMM模块102的MCPU1021与计算机设备的CPU203中的PCIE Switch201通过PCIE链路和管理通道mChannle相连，PCIE设备(例如CNA/RAID/SSD等)通过PCIE链路直接与计算机设备的CPU203连接，计算机设备的CPU203内部集成一个PCIE Switch201，该PCIE Switch201可以通过一个能够完成该PCIE Switch功能的芯片来实现。
图3中，PCIE Switch201还与CPU203内部的RC(Root Complex)204连接，该RC204是PCIE网络的根节点。CPU203的RC204连接PCIE Switch201的一个端口(可配置为上行端口)，SMM102模块通过mChannle通道修改PCIE Switch201的上行端口实现对PCIE Switch201的连接控制，即建立MCPU1021与PCIE Switch201的连接，将所述PCIE Switch与所述SMM之间的PCIE端口配置为上行端口，或将所述RC204与PCIE Switch201之间的PCIE端口配置为上行端口；SMM102中的MCPU1021还通过PCIE链路与PCIE Switch201连接，实现对PCIE设备(例如CNA/RAID/SSD等)进行配置管理，而不依赖于计算机设备的操作系统或者PCIE设备提供的特殊配置通道。
参考图4，图4为本发明实施例一种计算机设备400的结构示意图，包括高速外围组件互连PCIE Switch 401，系统管理模块SMM 402，中央处理器 CPU403和至少一个PCIE设备404，其中：

作为一种可选的实现方式，本发明实施例中，当所述SMM402通过与所述PCIE Switch401之间的PCIE链路实现对所述至少一个PCIE设备404进行配置管理时，所述SMM402通过所述管理通道将所述PCIE Switch401与所述SMM402之间的PCIE端口配置为上行端口。
进一步的，当所述SMM402对所述至少一个PCIE设备404进行配置管理之后，所述SMM402通过所述管理通道将所述PCIE Switch401与所述CPU403之间的PCIE端口配置为上行端口。

步骤504：在所述SMM完成对所述至少一个PCIE设备的配置管理时，所述SMM通过管理通道将所述PCIE Switch与所述CPU之间的PCIE端口配置为上行端口。
上述方法通过在系统启动的不同阶段控制SMM和CPU与PCIE Switch连接，使得SMM与PCIE Switch连接时，PCIE Switch断开与CPU的连接，在实现PCIE设备管理时，不依赖于计算机设备CPU的参与，不仅在不需要计算机设备操作系统参与的情况下实现PCIE设备的配置管理，还节省了CPU的资源；实现了SMM模块对PCIE设备的带外管理，降低和计算机设备的耦合性，提升了计算机设备的可管理性，满足大型数据中心对计算设备简化管理的要求。同时，PCIE设备通过下行端口与PCIE Switch相连，不需要配置特殊的接口与SMM相连，简化了系统的配置。
