Description
技术领域
本发明是有关于一种服务器丛集及其控制机制。
背景技术
刀锋服务器由于利用模块化设计进行优化以尽可能减少使用物理空间及能量,故可精简服务器架构。然而,刀锋服务器必须依靠人力操作或是由管理人员通过操作远程管理服务器以控制刀锋服务器的基板管理控制器(Baseboard Management Controller,BMC)来关闭电源。上述的机制必须要利用远程管理服务器及基板管理控制器,无法有效降低刀锋服务器的成本。
发明内容
本发明是有关于一种服务器丛集及其控制机制,利用检测网络的一关机封包以关闭服务器节点的电源,不需通过基板管理控制器,可有效降低刀锋服务器的成本并达到将服务器节点关机的目的。
根据本发明的第一方面,提出一种服务器丛集,包括一网络交换机以及多个服务器节点。网络交换机连接至一外部网络。每一服务器节点执行一操作系统,并各自包括一网络端口、一网络芯片及一南桥芯片。网络端口用以经一网络线连接至网络交换机。网络芯片用以当网络交换机启动后,依据所接收到的一关机封包输出一关机信号。南桥芯片用以当服务器节点为开机状态且操作系统正常工作时,依据关机信号输出一中止信号以中止服务器节点。
根据本发明的第二方面,提出一种服务器丛集的控制机制,服务器丛集包括一网络交换机以及多个服务器节点。每一服务器节点执行一操作系统,并各自包括一网络端口、一网络芯片及一南桥芯片。网络交换机连接至一外部网络。网络端口经一网络线连接至网络交换机。服务器丛集的控制机制包括下列步骤。启动网络交换机。利用网络芯片依据所接收到的一关机封包输出一关机信号。当服务器节点为开机状态且操作系统正常工作时,利用南桥芯片依据关机信号输出一中止信号以中止服务器节点。

具体实施方式
本发明是有关于一种服务器丛集(server cluster)及其控制机制,利用检测网络的一关机封包以关闭服务器节点(server node)的电源,不需通过基板管理控制器(Baseboard Management Controller,BMC),可有效降低服务器丛集的成本并达到将服务器节点关机的目的。
请参照图1,其绘示依照一实施例的服务器丛集的示意图。服务器丛集100包括一网络交换机(network switch)110以及多个服务器节点120。网络交换机110用以连接至一外部网络,例如为一因特网。每一服务器节点120包括一网络端口(port)124、一网络芯片126、一南桥(south bridge)芯片128及一脉冲延迟电路130。网络端口124经一网络连结122,例如网络线(cable),连接至网络交换机110。网络芯片126用以当网络交换机110启动后,依据所接收到的一关机封包输出一关机信号。此关机封包例如为一网络重开机(Reboot on LAN,ROL)封包或一网络唤醒(Wake on LAN,WOL)封包,然不限于此。南桥芯片128电性连接至网络芯片126;脉冲延迟电路130电性连接至网络芯片126及南桥芯片128。
对应于服务器丛集100,本发明亦提出一种服务器丛集的控制机制。请参照图2,其绘示依照一实施例的服务器丛集的控制机制的流程图。于步骤S200中,启动网络交换机110。于步骤S210中,网络芯片126接收到关机封包,并据以输出关机信号PWR_OFF_L。于步骤S220中,判断服务器节点120是否为开机状态。若服务器节点120为关机状态,则南桥芯片128及脉冲延迟电路130均不动作,回到步骤S200。若服务器节点120为开机状态,则于步骤S230中,判断服务器节点120所执行的操作系统是否为非正常状态,例如当机或hang-up等。
当服务器节点120所执行的操作系统为正常状态或正常工作,则于步骤S240中,南桥芯片128的一系统管理中断(System Management Interrupt,SMI)脚位被关机信号PWR_OFF_L致能产生一中止信号SCI以通知操作系统中止服务器节点120。于步骤S250中,服务器节点120被中止。另一方面,当服务器节点120所执行的操作系统非正常(hang-up),则于步骤S260中,脉冲延迟电路130将关机信号PWR_OFF_L转换为一延迟信号并送至南桥芯片128,使得南桥芯片128输出一电源信号PWR_BUT_L中止服务器节点120。
在上述的机制中,脉冲延迟电路130实质上会通过南桥芯片128的一信号SLP_S5_L来检测服务器节点120的开关机状态;脉冲延迟电路130并于服务器节点120为开机状态且操作系统为正常状态时将关机信号PWR_OFF_L转换为具有一脉冲宽度达4秒的低电平脉冲的延迟信号。在目前既有的规范下,此脉脉冲宽度达4秒的低电平脉冲会使得南桥芯片128强迫操作系统中止服务器节点120。
请参照图3,其绘示依照一实施例的脉冲延迟电路的一例的电路图。在脉冲延迟电路130中,脉冲宽度仅为几毫秒的关机信号PWR_OFF_L先被反相,再经由RC电路延迟脉冲宽度,最后依据信号SLP_S5_L在服务器节点120为开机状态时输出并反相为具有一脉冲宽度至少达4秒的低电平脉冲的延迟信号。
本发明上述实施例所揭露的服务器丛集及其控制机制,利用检测网络的一关机封包,例如为网络重开机(ROL)封包或一网络唤醒(WOL)封包,通过简易的逻辑电路即可达到关闭服务器节点电源的目的,不需通过基板管理控制器,可有效降低服务器丛集的成本。
综上所述,虽然本发明已以多个实施例揭露如上,然其并非用以限定本发明。本发明所属技术领域中具有通常知识者,在不脱离本发明的精神和范围内,当可作各种的更动与润饰。因此,本发明的保护范围当视所附的权利要求范围所界定者为准。
