具体实施方式
下文中将参考附图并结合实施例来详细说明本申请的实施例。
需要说明的是,本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象,而不必用于描述特定的顺序或先后次序。
除非另有定义,本申请所使用的所有的技术和科学术语与属于本申请的技术领域的技术人员通常理解的含义相同。在本申请的说明书中所使用的术语只是为了描述实施方式的目的,不是旨在于限制本申请。
需要说明的是,现代化数据中心(相当于上述实施例中的数据中心)皆须对所部署之服务器及机柜进行U位(或称为U空间)管理,以实现如下用途1-5:
用途1:实现空间规划。通过U位管理,可以有效规划和管理机房内设备的空间。管理员可以预先计划每个机架的U位分配,确保设备安装整齐有序,便于维护和管理。
用途2:实现散热和通风。确保服务器和其他设备之间有足够的空间,有助于良好的散热和通风。合理的U位管理可以防止设备之间过于密集,导致散热不足,影响设备性能和寿命。
用途3:便于维护和更换。当需要维护或更换设备时,U位管理可以帮助管理员快速定位并访问目标设备。这使得维护工作更加高效,减少了停机时间。
用途4:实现电缆管理。通过U位管理,可以更容易地管理设备之间的电缆。这包括电源线、网络线等。清晰的电缆管理有助于减少故障风险,并简化对电缆的跟踪和调整。
用途5:便于资源规划。在U位中安装设备时,管理员可以更好地规划资源,确保机架空间被充分利用,同时留有一定的余地以适应未来的扩展。
为实现上述U位管理用途,一个典型的数据中心U位管理架构需要执行如下内容:1)制定一个全面的U位编号和标识系统,确保每个U位都有唯一的标识符。2)创建详细的机架布局图,标明每个机架上的U位分配情况和设备信息。这个图纸可以在数据中心的物理空间和电力分布方面提供有用的信息。3)实施有效的电缆管理策略,包括横向和纵向电缆的整齐摆放,以减少混乱和提高可维护性。使用标签和颜色编码,使电缆易于识别。4)强调U位的物理安全性,确保只有授权人员能够访问机架和设备。这可能涉及到锁定机架、使用监控摄像头等安全措施。5)结合远程监控和自动化工具,以便管理员可以远程监控设备状态、实施变更和执行维护操作。这有助于减少人工干预和提高响应速度。相关技术中,典型的数据中心的U位管理架构如图1所示,典型的数据中心的U位管理架构对应的设备图如图2所示。基于图1和图2可知,典型的数据中心为实现U位管理,其架构中需要增设U位管理模块、U位网关、U位资产物联标签(相当于图2中的U位资产标签)、扩展模块、U位管理专责交换机设备等设备。其中,扩展模块、U位资产标签等则是需要为每个机柜都设置,从而导致典型的数据中心的U位管理架构需要额外增设大量设备、构建成本较高。
为解决上述问题,本申请实施例提供了一种标识符的分配系统,图3是根据本申请实施例的标识符的分配系统的架构图,该标识符的分配系统包括如下:
供电电源31,供电电源内部设置有电力线通信电路311;其中,
供电电源31,被设置为在数据中心需要为目标设备32分配标识符的情况下,为目标设备32供电,以及将为目标设备32分配的标识符传输至目标设备32;其中,目标设备32为至少一个机柜单元中的设备,且标识符用于在至少一个机柜单元中唯一标识目标设备32,标识符还用于将目标设备32的设备信息与目标设备32在至少一个机柜单元中的U位位置唯一关联。
需要说明的是,目标设备的设备信息包括但不限于目标设备的供电信息、功耗信息等。
可选的,上述目标设备包括但不限于服务器、交换机、存储设备等。服务器、交换机、存储设备等均可以设置在至少一个机柜单元中。可选的,每个供电电源为供电电源唯一连接的目标设备供电以及传输目标设备被分配的标识符。
通过本申请,供电电源,供电电源内部设置有电力线通信电路;其中,供电电源,被设置为在数据中心需要为目标设备分配标识符的情况下,为目标设备供电,以及将为目标设备分配的标识符传输至目标设备;其中,目标设备为至少一个机柜单元中的设备,且标识符用于在至少一个机柜单元中唯一标识目标设备,标识符还用于将目标设备的设备信息与目标设备在至少一个机柜单元中的U位位置唯一关联。也就是说,内部设置有电力线通信电路的供电电源,允许同时为至少一个机柜单元中的目标设备供电、以及为目标设备传输目标设备被分配的允许唯一标识目标设备的标识符;因此,可以解决现有技术中数据中心架构中需要为每个机柜额外增设设备进行U位标识符的传输,导致数据中心架构的构建成本高的问题。进而通过设置有电力线通信电路的供电电源即可在为目标设备供电的同时,也为目标设备传输被分配的标识符,从而降低了数据中心架构的构建成本。
可选的,电力线通信电路,包括:耦合器,与交流输电线串联,被设置为将从交流输电线接收到的电力信号解耦为低频供电信号和第一高频通信信号,其中,第一高频通信信号携带有标识符,交流输电线被设置为传输电力信号;第一微处理器,与耦合器串联,被设置为对第一高频通信信号进行解码,得到标识符,并将标识符发送给目标设备。
可选的,第一微处理器,还被设置为将从目标设备接收到的数据,编码为第二高频通信信号。
耦合器还被设置为将从第一微处理器接收到的第二高频通信信号传输给交流输电线。其中,交流输电线还被设置为传输第二高频通信信号。
可以理解的是,在第一高频通信信号或第二高频通信信号输入到交流输电线中,即可实现信号的耦合。例如,第一高频通信信号输入到交流输电线中,与交流输电线中的低频供电信号耦合,得到电力信号。
可选的,本申请实施例中的供电电源串联在交流输电线与目标设备之间,进而电力线通信电路也串联在交流输电线与目标设备之间。电力线通信电路中包括的耦合器和第一微处理器在标识符的分配系统中的连接方式是:耦合器分别与交流输电线和第一微处理器串联、第一微处理器分别与耦合器以及目标设备串联。可选的,本申请实施例中的低频供电信号采用220V/60Hz,高频通信信号可以采用5V/100KHz,高频通信信号包括:第一高频通信信号和第二高频通信信号。
因此,本申请实施例通过耦合器和第一微处理器,实现了同时为目标设备供电以及传输目标设备被分配的标识符的目的;避免了相关技术中,需要为数据中心配置额外设备以进行标识符传输造成的成本耗费问题,同时也节约了数据中心架构的物理空间。
可选的,耦合器,包括:耦合变压器,被设置为将接收到的电力信号传输到有源带通滤波器组,或者被设置为将从有源带通滤波器组接收的第二高频通信信号传输到交流输电线;有源带通滤波器组,与耦合变压器串联,被设置为从电力信号中分离出低频供电信号和第一高频通信信号,或者被设置为放大第二高频通信信号。
耦合器,还包括:第一电容,第一电容的第一端口串联到交流输电线,第一电容的第二端口串联耦合变压器的输入端口。可选的,第一电容被设置为过滤电力信号中的干扰和噪声。
可以理解的是,本申请实施例中,耦合器中还包括耦合变压器和有源带通滤波器组。在耦合器从交流输电线接收到电力信号的情况下,耦合变压器将电力信号传递给有源带通滤波器组,通过有源带通滤波器组将低频供电信号和第一高频通信信号分离,进而低频供电信号用于为目标设备供电、第一高频通信信号用于将携带的标识符传输给目标设备。可选的,第一高频通信信号也可以携带其他需要传输给目标设备的传输信息,本申请实施例对此不作限定。
在耦合器从第一微处理器接收到第二高频通信信号的情况下,有源带通滤波器组被设置为将第二高频通信信号放大,并通过耦合变压器传输到交流输电线中。
可选的,耦合变压器也可以实现从电力信号中分离出高频通信信号和低频供电信号。可选地,耦合变压器可以通过设计合适的电路结构来分离高频通信信号和低频供电信号。通常情况下,耦合变压器的磁芯和绕组会有不同的频率响应特性,磁芯会对高频信号具有较好的响应,而对低频信号的响应相对较弱,而绕组则可能具有相反的特性。通过合理设计磁芯和绕组的参数,可以使得高频信号更多地被传递到一个绕组中,而低频信号更多地被传递到另一个绕组中;也即,此种情况下,耦合变压器的二次侧需要存在只至少两个绕组。此外,也可以在耦合变压器加入滤波器,以分离高频信号和低频信号,从而在输出端得到经过滤波的高频信号和低频信号,从而实现信号的分离。
总的来说,耦合变压器通过设计合适的电路结构和参数,以及引入滤波器等方法,可以有效地分离高频信号和低频信号。
因此,本申请实施例通过耦合器中的耦合变压器和有源带通滤波器组实现了对电力信号的分离和/或对第一高频通信信号的放大处理,从而使得供电电源本身同时具备了通过低频电力信号供电以及对高频通信信号进行传输的功能。
在一个示例性实施例中,有源带通滤波器组,包括:输入有源带通滤波器,被设置为从电力信号中过滤出第一高频通信信号,并放大第一高频通信信号;输出有源带通滤波器,与输入有源带通滤波器并联,被设置为放大第一微处理器输出的第二高频通信信号。
目标滤波器包括低通滤波器,以及与低通滤波器串联的高通滤波器,其中,目标滤波器包括以下至少之一:输入有源带通滤波器、输出有源带通滤波器。
可以理解的是,本申请实施例中的有源带通滤波器组包括至少两个有源带通滤波器,至少两个有源带通滤波器包括:输入有源带通滤波器、输出有源带通滤波器。两个有源带通滤波器都是由串联在一起的低通滤波器和高通滤波器构成的。需要说明的是,高通滤波器的截止频率一定要小于低通滤波器的截止频率。
本申请通过输入有源带通滤波器、输出有源带通滤波器,可以在目标设备和交流输电线之间双向传输高频通信信号,从而为连接在交流输电线的目标设备与预设管理平台提供了通信信号传输方案。
在一个示例性实施例中,耦合器,还包括:第二电容,第二电容的第三端口串联耦合变压器的输出端口,第二电容的第四端口串联输入有源带通滤波器;第三电容,第三电容的第五端口串联耦合变压器的输出端口,第三电容的第六端口串联输出有源带通滤波器。

可以理解的是,预设管理平台还起到对至少一个机柜中包括的所有U位的监控管理作用,与至少一个机柜单元中的目标设备的高频通信信号通过目标设备的供电电源传输。
还包括:电力线通信数据机,电力线通信数据机分别与预设管理平台和交流输电线串联,被设置为将预设管理平台为目标设备分配的标识符编码为第一高频通信信号;电力线通信数据机,还被设置为将第二高频通信信号解码得到数据之后,将数据传输至预设管理平台,其中,第二高频通信信号携带有目标设备向预设管理平台传输的数据。
可以理解的是,本申请实施例通过预设管理平台为目标设备分配标识符。可选的,预设管理平台可以是U位管理平台,可以通过电力线通信数据机与交流输电线完成高频通信信号的传输。可选的,电力线通信数据机可以是PLC数据机(PLC modem),其中,电力线通信(Power Line Communication,简称为PLC)。

可选的,本申请中的具电力线通讯功能电源的构建流程如下,包括:
步骤S61:数位化电源构建。
数位化电源构建,即服务器电源构建。相关技术中,服务器电源架构如图6所示,包括:电磁干扰(Electromagnetic Interference,简称为EMI)滤波模块(相当于上述实施例中的电磁干扰过滤电路)、功率因数校正(Power Factor Correction,简称为PFC)交流/直流(Alternating Current/Direct Current,简称为AC/DC)功率模块、直流/直流(Direct Current/Direct Current,简称为DC/DC)转换模块、辅助源模块、电源控制模块五大功能模块。
EMI滤波模块是电源安规及EMC(Electro Magnetic Compatibility,电磁兼容性)测试关键设计模块,影响安规及EMC测试。PFC AC/DC功率模块被设置为AC/DC功率转换,可以将输入交流或者高压直流转化为约400V直流(Direct Current,简称为DC)二阶供电,另外还可以实现供电的功率因数校正;PFC AC/DC功率模块所需的关键拓扑可为无桥PFC,硬开关PFC。
DC/DC转换模块是关键功率转换模块,被设置为将400V直流电通过开关器件及变压器转换为12V/54V输出为服务器系统供电;DC/DC转换模块的关键拓扑可为谐振电感电容(inductor-inductor-capacitor,简称为LLC)谐振半桥,LLC谐振全桥,移相全桥,双相交错式LLC全桥。辅助源模块,被设置为为交流(Alternating Current,简称为AC)电源内部初次级控制器及驱动的隔离供电。关键拓扑可为返驰式或准谐振式。
电源控制模块(相当于上述实施例中的电源控制电路):现行服务器电源供应器(Server Power Supply Unit,简称为Server PSU)会由微处理器(Microcontroller Unit,简称为MCU)来完成电源供应器中转换器开关控制、风扇控制、发光二极管(Light Emitting Diode,简称为LED)控制、监控、保护、通讯等功能。
电源控制模块会分工为一次侧(PRIMARY Side)MCU及二次侧(SECONDARY Side)MCU。其中,一次侧MCU主要功能包括:功率因数校正电路(PFC)开关控制、AC输入电压电流监控与保护、涌浪电流(Inrush Current)保护开关控制、通信功能如通用异步收发器UART(即非同步收发传输器)、串行外围接口(Serial Peripheral Interface,简称是SPI)、I2C(Inter-Integrated Circuit)等、现场可更换单元(Field Replace Unit,简称为FRU)资料储存。
其中,I2C是一种串列通讯汇流排,有完整通讯协定。
二次侧MCU主要功能包括:高效率转换器(DC DC)开关控制DC输出电压电流监控与保护电源供应器(Power Supply Unit,简称为PSU)风扇控制与过温、通信功能如UART、SPI、I2C等。
步骤S62:PLC规范选定。
从占用频率带宽角度,可分为窄带PLC(NB-PLC)和宽带PLC(BB-PLC)。其中,窄带PLC的载波频率范围:在不同国家、不同地区是不一样的,美国为50~450kHz,欧洲为3~148.5kHz(95kHz以下用于接入Access通信,95kHz以上用于户内In-house通信),中国为40~500kHz。
宽带PLC的载波频率范围:在美国为4~20MHz(HomePlug Specification v 1.0),主要用于户内;欧洲为1.6~10MHz(Access)和10~30MHz(In-House);中国尚无宽带PLC的标准。从实现的通信速率来看,可分为低速PLC(LS-PLC)和高速PLC(HS-PLC),一般以2Mb/s线速为分界线。通常,NB-PLC等同于LS-PLC,BB-PLC等同于HS-PLC。另一种分类方法是按应用场合的不同。
本申请采用国内最适窄带PLC的载波频率范围40~500kHz,并且需低于0.15MHz(150KHz)避免传导及辐射骚扰的问题再加上仪器测试误差,因此本申请实施例以100KHz为通信传输率。因为很多单片机的工作电压是5V,因为大多数控制器都是5V的TTL电平,因此决定为5V工作震幅。
基于上述内容,本申请实施例将220V/60Hz低频电力讯号和高频的通信信号5V/100KHz通过耦合器结合之后再传输出去。220V/60Hz低频电力(相当于上述实施例中的低频供电信号)和高频通信信号5V/100KHz的耦合如图7所示。反之在接收端将高频的通信信号和低频电力信号经过耦合器分离后,就可以得到需要的数据传输。PLC电力信号经解耦合为220V/60Hz低频电力信号和高频通信信号5V/100KHz如图8所示。
步骤S63:将PLC模组(相当于上述实施例中的电力线通信电路)与服务器电源结合为具电力线通讯功能电源。
将PLC MCU(相当于上述实施例中的第一微处理器)及PLC Coupler(耦合器)置入电源与一次侧MCU(相当于上述实施例中的第二微处理器)结合使电源具有电力线通信功能。其中,具电力线通讯功能电源架构图如图9所示。具电力线通讯功能电源与目标设备和交流输电线连接后,对应的架构图如图10所示。
上述PLC模组的构建过程如下,包括:
步骤S631:PLC MCU选型。
电力线载波MCU是一种SOC(System on Chip,系统级控制器)载波通讯功能,主要参数是载波中心频率,频带及调制方式、以及对MCU部分的参数要求。选择用于电力线通信的MCU时,需要考虑一些特定的因素,以确最终选择的MCU能够适应应用需求。以下是一些本申请可选实施例选型可能需要考虑的关键因素,包括:1)通信标准和协议:了解电力线通信系统所需的标准和协议。常见的电力线通信标准包括ITU G.9903(G3-PLC)和HomePlug等。2)频率范围:确保MCU的电力线通信模块支持计划在其上运行的频率范围为建议值的100KHz。3)噪声和干扰抵抗性:由于电力线通信环境可能存在噪声和干扰,选择具有良好抵抗性的MCU。4)数据速率:根据应用需求选择支持足够数据速率的MCU。不同的电力线通信标准支持不同的速率。5)集成性:一些MCU可能集成了电力线通信模块,这有助于简化设计和减少系统成本。6)功耗:如果应用对功耗有严格的要求(例如,电池供电的设备),选择功耗较低的MCU。7)外设接口:确保MCU具有足够的外设接口,以连接传感器、执行器或其他外部设备。8)可编程性:选择易于编程的MCU,以便灵活适应不同的通信需求和算法。9)安全性:根据应用对安全性有要求,确保MCU支持必要的安全特性和协议。
步骤S632:PLC Coupler(耦合器)选型以及构建。
PLC Coupler(耦合器)主要功能在于电力线通讯功能与电力线间的连接,负责信号的接收与传输并隔离高电压对PLC MCU接口的影响。PLC Coupler(耦合器)主要包括:高压电容器(HV Cap)、耦合变压器(Coupling Transformer)3、有源带通滤波器(OPA Band-pass Filter,简称为OBPF)。PLC Coupler(耦合器)架构图如图11所示。
需要说明的是,高压电容器(HV Cap),其作用及选型类似电磁干扰滤波器(EMI Filter)中的Y电容,分别跨接在电力线两线和地之间。主要的目的是将隔绝高频切换杂讯,通过Y电容释放到另一侧,避免通过输入线路辐射出去,降低杂讯干扰。在这些用途中可能需要承受高电压等较大应力,因此需要使用已获得所有相关标准认证的电容。按绝缘等级,Y电容分为Y1、Y2、Y3、Y4。其中,Y1耐高压大于8kV,Y2耐高压大于5kV,Y3耐高压n/a,Y4耐高压大于2.5kV。其容值通常在PF级别,GJB151规定Y电容的容量应不大于0.1uF。
需要说明的是,耦合变压器作为一种1:1高频隔离变压器,下图12为PLC高压电容器与耦合变压器线路图。隔离变压器是指输入绕组与输出绕组带隔离的变压器,隔离变压器用以避免偶然同时触及带电体,变压器的隔离是隔离原副边绕线圈各自的电流。一次侧、二次侧绕组间有较高绝缘强度以隔离不同电位、抑制共模干扰的专用变压器。隔离变压器的变比通常是1:1。隔离变压器属于安全电源,一般用来机器维修、保养用,起保护、防雷、滤波作用。隔离变压器的原理和普通变压器的原理是一样的。都是利用电磁感应原理。隔离变压器一般(但并非全部)是指1:1的变压器。由于次级不和大地相连。次级任一根线与大地之间没有电位差,使用安全。常用作维修电源。控制变压器和电子管设备的电源也是隔离变压器。如电子管扩音机、电子管收音机与示波器,以及车床控制变压器等电源都是隔离变压器。
需要说明的是,本申请可选实施例中的有源带通滤波器包括:PLC Input OPA(Operational Amplifier,运算放大器)有源带通滤波器(相当于上述实施例中的输入有源带通滤波器)、PLC Output OPA有源带通滤波器(相当于上述实施例中的输出有源带通滤波器)。其中,OPA是运算放大器(Operational Amplifier,简称是OPA)。
其中,PLC Input OPA有源带通滤波器,目的在分离PLC 60Hz低频和高频的通信信号5V/100KHz并作信号放大。PLC 100KHz输入有源带通滤波器示意图如图13所示。带通波形图如图14、图15所示。带通滤波器它的通频带在fL~fH之间。它使信号中高于fL而低于fH的频率成分可以不受衰减地通过,而其它成分受到衰减。实际上将低通滤波器和高通滤波器串联,即可构成带通滤波器,此处需要注意高通滤波器的截止频率一定要小于低通滤波器的截止频率即fH<fL,否则新构成的滤波器就会变成全频滤波器。
可选的,上述PLC 100KHz输入有源带通滤波器设计方法包括:
1)已确定中心频率fc=100KHz、且中心频率公式,可将设计设定为C1=C2=C,R3=R4=R,公式可以再次设计简化;
2)为将设计简化,确定信号增益A=2,设定为R1=R2=R,则根据信号增益公式A=1+R1/R2,此时信号增益即为A=1+R/R=2。
3)设定R1=R2=R3=R4=10k,则C=1/(2π*100K*10K)=15.9nF,可得C1=C2=15.9nF。
PLC Output OPA输出信号放大级(相当于上述实施例中的输出有源带通滤波器),常用于类比电路中(如声音、温度、速度、压力、波形)。放大器是用来将微弱信号转换成较大信号的装置,可设计为电压放大、讯号放大及功率放大。在本申请可选实施例中,被设置为将PLC MCU输出信号(相当于上述实施例中的第二高频通信信号)放大,并通过耦合变压器将5V/100KHz信号在输出到交流输电线。
而采用两级OPA(Operational Amplifier,运算放大器)设计的原因主要有几点:1)增益调节:两级OPA设计可以提供更灵活的增益调节。第一级OPA可以提供初始的增益,而第二级OPA可以调节总体增益。这使得设计者可以根据特定的应用需求调整放大器的放大倍数。2)带宽控制:第一级OPA通常被设置为提高带宽,而第二级OPA被设置为精细调整。这种设计可以使系统更好地适应不同频率的信号,并在需要时提供更高的带宽。3)稳定性:两级OPA设计有助于提高系统的稳定性。第一级OPA可以提供足够的增益,而第二级OPA可以通过反馈回路来确保稳定性,减少可能的振荡和失真。4)噪声性能:两级设计可以在不同级别上优化噪声性能。第一级OPA可以在低频范围内降低输入噪声,而第二级OPA可以处理高频噪声,以提高整体的信噪比。5)放大器增益设计:总增益Atotal=A1 x A2,可将设计设定为R5=R6=R7=R。其中,A1=1,如图16所示;A2=R5/R6,如图17所示。因此,此时信号增益即为A2=1+R/R=2,Atotal=A1 x A2=1x2=2,可统一设计R5=R6=R7=10k。可选的,PLC 100KHz输出有源带通滤波器如图18所示。
步骤S633:与电源一次侧MCU及整合。
PLC模组与电源一次侧MCU结合为具电力线通讯功能电源。可选地,PLC MCU与电源一次侧MCU通过通用非同步收发传输UART通信方式连接,MCU中的UART连接在MCU的通用型之输入输出的简称脚位结合(General-purpose input/output,简称为GPIO),其中,UART通用非同步收发传输是一种非同步收发传输器,是电脑硬体的一部分,将资料通过串列通讯进行传输。
需要说明的是,UART通常用在与其他通讯介面(如EIA RS-232)的连接上。实物表现为独立的模组化晶片,或是微处理器中的内部周边装置(peripheral)。一般和RS-232C规格的、类似Maxim的MAX232之类的标准讯号振幅变换晶片进行搭配,作为连接外部装置的介面。在UART上追加同步方式的序列讯号变换电路的产品,被称为USART(Universal Synchronous Asynchronous Receiver Transmitter,通用同步/异步串行接收/发送器)。PLC模组与电源一次侧MCU结合后得到的PLC PSU电源控制板架构如图19所示,结合后的服务器电源即具电力线通讯功能。
通过上述供电电源即可实现对目标设备U位ID(Identity,身份标识)的管理。可选地,在目标设备是服务器的情况下,服务器BMC通过供电电源接收到U位ID((相当于上述实施例中,通过供电电源传输给目标设备的标识符)之后,允许服务器BMC对U位ID管理。
需要说明的是,U级定位,又称U位(级)资产管理,简而言之就是对数据中心机柜内的IT(Information Technology,信息技术)设备进行精准定位和空间资源的管理。目前就是以RFID(Radio Frequency IDentification,无线射频识别)技术为主的U位物联产品,可以解决服务器资产的实时盘点、定位、在线查询、U位利用率等问题。U位资产管理,在继承了RFID标签优点的同时,完全解决了RFID技术在机房U位资产管理应用场景中的缺陷,具有高可靠性、高准确性、精准定位、免维护的特点。机房U级定位经历过3个阶段:第一代技术:接触式电子标签,集成电路卡即接触式ID/IC(Integrated Circuit,集成电路)卡;第二代技术:非接触式RFID电子标签;第三代技术:无源主动式RFID。本申请可选实施例提供第四代技术:使用服务器BMC对服务器电源写入U位ID管理。
可选地,服务器BMC对U位ID管理实现分为以下两部分:部分一、PSU在FRU EEPROM(Electrically Erasable Programmable Read-Only Memory,电可擦可编程只读存储器)的位置扩充;部分二,服务器BMC对服务器电源写入U位ID。
部分一、PSU在FRU EEPROM的位置扩充。
现场可更换单元(Field Replace Unit,简称为FRU)。一般都是用在伺服器(即服务器)上的一些可更换的元件。例如主机板、电源供应器、风扇等,如果它是一个FRU就能直接快速更换。一般的伺服器产品中,都会把FRU的资讯(版厂,或是产品编号等)烧入在非挥发记忆体中(例如EEPROM,SPI flash),有些公司会把这些资讯称作为VPD(Vital product data,重要产品数据),有些直接称作FRU data。本申请可以通过读取FRU data得到该元件的厂商,产品编号等讯息。FRU data的长度和offset会随着内容而变化,内容是由底下六个区域组合而成的,除了Common Header以外,其他区域都是可要可不要的。
六个区域包括:1)Common Header:这个栏位是一定会存在的,用于定义其他区域的offset;2)Internal Use Area:通常保留给firmware做非挥发记忆体使用;3)Chassis Info Area:用于纪录chassis的相关资讯,系统上只能拥有一个这个区域;4)Board Info Area:Board info,如打板日期、板厂、S/N number等;5)Product Info Area:如果FRU本身就是个产品,就会有这个区域;6)MultiRecord Info Area:MultiRecord信息区域,提供了一种扩展FRU信息规范以覆盖新的信息类型而又不影响现有区域定义的机制。
相关技术中的PSU FRU指令表如图20所示,本申请实施例在指令9Eh下方新增指令9Fh,用于BMC向服务器电源二次侧MCU写入U位ID。其中,新增指令9Fh的内容包括:
Command ID:9Fh;
Command Name:MFR_U_ID;
SMBus Transaction Type:Write Block;
#of Data Bytes(Decimal):15;
Format:ASCII;
Power On Default Value:n/a;
基于上述新增指令9Fh,U位ID整字串即为1个15码编号。
例如:写入0Fh,36h,58h,58h,58h,58h,30h,31h,30h,31h,38h,33h,36h,5Ah,42h,30h=“6XXXX0101E36ZB0”。
部分二,服务器BMC对服务器电源写入U位ID。
服务器系统需要随时从服务器电源(Server PSU)读取及写入各种参数,以便做电源管理与系统最佳化。读取内容可分类为电压参数,电流参数,温度参数,功率参数,风扇转速等。服务器利用BMC透过I2C Bus(硬体层)访问伺服器电源,透过IPMI指令集(软体层)利用PMBus1.2规范,从Server PSU获取各项读值。I2C路径上有串接元件通信架构如图21所示,服务器BMC即可对服务器电源使用IPMI指令集(软体层)写入U位ID,并写入在PSU二次侧MCU。其中,IPMI(Intelligent Platform Management Interface)是一种Intel架构的企业系统的外围设备所采用的一种工业标准。
服务器BMC对Server PSU写入U位ID流程如图22所示,包括如下步骤S2201至S2205:
步骤S2201:U位运营管理平台(相当于上述实施例中的预设管理平台)软件产生U位ID编号。
步骤S2202:服务器BMC接收到U位ID编号,判定U位ID编号的设定服务器是否为本台服务器;如果不是,要求U位运营管理平台确认PLC路径(也即,确认供电电源),如果是,则执行步骤S2203。
步骤S2203:服务器BMC判定接收到的U位ID编号是否与本台服务器的目前编号重复,如果重复,则U位运营管理平台重新提供U位ID;不重复则执行步骤S2204。
步骤S2204:服务器PSU写入U位ID是否成功,如果成功,则执行步骤S2205,否则回到步骤S2203,通过I2C路径告知BMC重新写入。
步骤S2205,PSU完成U位ID写入。
还需要说明的是,本申请实施例具电力线通讯功能电源连接在服务器上,其设计可直接搭接在电力线的火线(L:live wire)及中性线(N:neutral wire)上。透过电源中的PLC模组传递及沟通信号。根据电力线容量搭接相对应的设备形成通讯电源网。
在U位运营管理平台通过PLC数据机(PLC modem)(相当于上述实施例中的电力线通信数据机)与通讯电源网接收与传递讯息,如图23所示。PLC数据机是通过电力线进行宽频上网的Modem,它具有即插即用的特点,俗称“电力猫”。目前上网有多种技术,第一种是电话线的拨号(即xDSL方式),第二种是有线电视线路的Cable Modem方式,第三种是双绞线的乙太网方式,第四种是电力线上网,即电力线通信。本申请可选实施例中的运维管理系统可以透过以太网路接口RJ45与PLC通讯电源网连接。
