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,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。
以下描述中,为了说明而不是为了限定,提出了诸如特定系统结构、接口、技术之类的具体细节,以便透切理解本申请。然而,本领域的技术人员应当清楚,在没有这些具体细节的其它实施例中也可以实现本申请。在其它情况中,省略对众所周知的装置、电路以及方法的详细说明,以免不必要的细节妨碍本申请的描述。
本发明的实施例可被实现为计算机实现的过程(方法)、计算系统、或者诸如计算机程序产品或计算机可读介质等制品。计算机程序产品可以是计算机系统可读并且编码包括用于使计算机或计算系统执行示例过程的指令的计算机程序的计算机存储介质。计算机可读存储介质是非瞬态的计算机可读存储器设备。例如,计算机可读存储介质可经由易失性计算机存储器、非易失性存储器、硬盘驱动器、闪存驱动器、软盘或紧致盘和类似介质中的一个或多个来实现。
另外,本申请实施例中术语“和/或”,仅仅是一种描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况。另外,本文中字符“/”,一般表示前后关联对象是一种“或”的关系。
此外,本发明的说明书和权利要求书及附图中的术语“第一”和“第二”等是用于区别不同对象,而不是用于限定特定顺序。本发明实施例中所描述的“上”、“下”、“左”、“右”也只是参考附图对本发明进行说明,不作为限定用语。
本发明的技术方案可以应用于各种使用硬盘的存储设备中,尤其适用于使用SSD的场景。
其中,SSD也被称作电子硬盘或者固态电子盘,是由控制单元和固态存储单元(动态随机存取存储器(Dynamic Random Access Memory,DRAM)或FLASH芯片)组成的硬盘。SSD在接口规范和定义、功能及使用方法上与普通硬盘相同,在产品外形和尺寸上也与普通硬盘一致。由于SSD没有普通硬盘的旋转介质,因而抗震性极佳。并且SSD与普通硬盘相比,拥有以下优点:1、启动快,没有电机加速旋转的过程;2、不用磁头,快速随机读取,读延迟极小;3、相对固定的读取时间,由于寻址时间与数据存储位置无关,因此磁盘碎片不会影响读取时间;4、写入速度极快;5、无噪音;6、内部不存在任何机械活动部件,不会发生机械故障,也不怕碰撞、冲击和振动;7、工作温度范围更大,即典型的硬盘驱动器只能在5到55摄氏度范围内工作,而大多数固态硬盘可在-10到70摄氏度工作,一些工业级的SSD还可在-40到85摄氏度,甚至更大的温度范围下工作。当然,SSD与普通硬盘相比,也具有成本高、容量低、写入寿命有限等缺点。
以计算机为例,现有的计算机能够将多个硬盘组装插入硬盘阵列框中,形成廉价硬盘冗余阵列(Redundant Arrays of Inexpensive Disks,RAID),RAID的结构示意图如图2所示。可见,一台计算机中能够插入的硬盘数量是有限的,一个SSD的容量也是有限的,从而限制了计算机的容量。本发明实施例提供一种级联式硬盘,级联式硬盘之间能够通过连接器相互连接,实现了在不增加存储设备接口的情况下对存储设备的扩容。
本发明实施例提供一种级联式硬盘20,该级联式硬盘20的结构示意图如图3所示,级联式硬盘20至少包括:第一连接器200,硬盘主体203,第二连接器201,以及与第一连接器200、硬盘主体203和第二连接器201均连接的级联芯片202。
其中,第一连接器200,用于与第一硬盘或存储设备电连接;第二连接器201,用于与第二硬盘电连接;级联芯片202,用于确定将接收到的数据传输至硬盘主体203或第二连接器201。所述的第一硬盘和第二硬盘,均可以是普通硬盘,也可以是级联式硬盘,在此不做具体限制。
可见,通过在级联式硬盘中设置与其他级联式硬盘级联的连接器,并通过级联式硬盘中设置的级联芯片实现级联式硬盘之间的数据交换,使得级联式硬盘之间可以互相连接,以形成级联式硬盘组,级联式硬盘组的容量相较于单个硬盘的容量大幅增长,实现了在不增加存储设备接口的情况下对存储设备的扩容。
其中,在本发明实施例的一种可能的实现方式中,上述第一连接器200和第二连接器201都为SAS连接器。相应的,上述级联芯片202可以为SAS级联芯片。在本发明实施例的另一种可能的实现方式中,上述第一连接器200和第二连接器201都为NVME连接器,或者SATA连接器,或者FC连接器。相应的,上述级联芯片202可以为NVME级联芯片、SATA级联芯片、FC级联芯片。
SAS级联芯片、NVME级联芯片、SATA级联芯片、FC级联芯片分别指的是采用SAS协 议、NVME协议、SATA协议,FC协议的级联芯片,其功能与级联芯片202的功能相同,区别仅在于实现其功能采用的协议不同。
进一步的,为了级联的两个级联式硬盘能够紧密连接,本发明实施例提供两种连接方式:
方式一:通过在级联式硬盘的外壳上设置固定装置,使得两个级联式硬盘能够紧密连接。
方式二:将级联式硬盘先固定在连接结构件上形成级联式硬盘模块,然后通过连接结构件上设置的固定件,使得两个级联式硬盘能够紧密连接。
为了便于理解,如图4所示,本发明一实施例以上述第一连接器200和上述第二连接器201均为SAS连接器,且以两个级联式硬盘采用方式一的连接方式达到紧密连接的效果,以第一硬盘和第二硬盘均为级联式硬盘为例,对本申请实施例提供的级联式硬盘进行具体介绍。
为了便于实现,通常第一SAS连接器100可以是一个公头,第二SAS连接器101可以是一个母头;或者,第一SAS连接器100可以是一个母头,第二SAS连接器101可以是一个公头,本发明对此不作具体限制。
需要说明的是,公头和母头一般指的是成套的连接件或者延长线的两端。公头通常为针型的一端,母头通常为插槽型的一端。
进一步地,如图5所示,硬盘主体103(如图5中虚线框所指示的部分)具体包括:与级联芯片102连接的控制芯片1030,与控制芯片1030连接的备电电容1031,与控制芯片1030和备电电容1031均连接的内存1032,以及与控制芯片1030连接的至少一个闪存FLASH 1033。
示例性的,以3个级联式硬盘级联为例,3个级联式硬盘级联的示意图如图6所示,为了便于描述,将图5中上方的级联式硬盘称为级联式硬盘A,将图5中中间的级联式硬盘称为级联式硬盘B,将图5中下方的级联式硬盘称为级联式硬盘C,级联式硬盘A、级联式硬盘B和级联式硬盘C级联后称为级联式硬盘组。可以看出,级联式硬盘A的第一SAS连接器100与存储设备中相应的接口连接,级联式硬盘A的第二SAS连接器101与级联式硬盘B的第一SAS连接器100连接,级联式硬盘B的第二SAS连接器101与级联式硬盘C的第一SAS连接器100连接。同时,级联式硬盘A、级联式硬盘B和级联式硬盘C中的级联芯片102能够协同控制存储设备下发的数据的存储。例如,对于存储设备下发的需要存储在级联式硬盘A的数据,存储设备通过级联式硬盘A的第一SAS连接器100将数据传输至级联式硬盘A的级联芯片102,级联式硬盘A的级联芯片102在确定出接收到的数据需传输至级联式硬盘A的硬盘主体103时,将接收到数据传输至级联式硬盘A的硬盘主体103进行存储。对于存储设备下发的需要存储在级联式硬盘B的数据,存储设备通过级联式硬盘A的第一SAS连接器100将数据传输至级联式硬盘A的级联芯片102,级联式硬盘A的级联芯片102在确定出接收到的数据需传输至级联式硬盘A的第二SAS连接器101时,将接收到数据传输至级联式硬盘A的第二SAS连接器101,以将数据传输至级联式硬盘B。级联式硬盘B的第一SAS连接器100接收到数据后,将数据传输至级联式硬盘B的级联芯片102,级联式硬盘B的级联芯片102在确定出接收到的数据需传输至级联式硬盘B的硬盘主体103时,将接收到数据传输至级联式硬盘B的硬盘主体103进行存储。对于需要存储在级联式硬盘C的数据,其存储过程与上述过程类似,此处不再赘述。级联式硬盘A、级联式硬盘B和级联式硬盘C级联后,级联式 硬盘组的容量为级联式硬盘A的容量、级联式硬盘B的容量和级联式硬盘C的容量之和,实现了在不增加存储设备接口情况下对存储设备的扩容。
可选的,为了级联的两个级联式硬盘10能够紧密连接,如图7所示,级联式硬盘10还包括:设置在级联式硬盘10的外壳上的第一固定装置104,以及设置在级联式硬盘10的外壳上的第二固定装置105。其中,第一固定装置设置在级联式硬盘外壳的与第一级联式硬盘连接的一侧,第二固定装置设置在级联式硬盘外壳的与第二级联式硬盘连接的一侧。
其中,第一固定装置104,用于与第一级联式硬盘固定连接,增强级联式硬盘10与第一级联式硬盘之间的作用力;第二固定装置105,用于与第二级联式硬盘固定连接,增强级联式硬盘10与第二级联式硬盘之间的作用力。
示例性的,以2个级联式硬盘级联为例,2个级联式硬盘级联的示意图如图8所示,为了便于描述,将图8中上方的级联式硬盘称为级联式硬盘A,将图8中下方的级联式硬盘称为级联式硬盘B,级联式硬盘A和级联式硬盘B级联后称为级联式硬盘组。可以看出,级联式硬盘A的第二固定装置105(卡槽结构)与级联式硬盘B的第一固定装置104(卡座结构)连接,级联式硬盘B的卡座结构卡入级联式硬盘A的卡槽结构中(如图8中局部放大的部分所示)。
具体的,级联式硬盘B的第一固定装置104和级联式硬盘A的第二固定装置105为配合使用的一对粘性结构,或者配合使用的一对磁性结构,或者配合使用的一对紧固件结构。
进一步地,若级联式硬盘B的第一固定装置104和级联式硬盘A的第二固定装置105为一对紧固件结构,级联式硬盘B的第一固定装置104可以为卡座结构,相应的,级联式硬盘A的第二固定装置105可以为卡槽结构,或者,级联式硬盘B的第一固定装置104可以为卡槽结构,相应的,级联式硬盘A第二固定装置105可以为卡勾结构。其中,卡座结构能够卡入卡槽结构中。
进一步地,卡槽结构中还可以设置有弹簧,一方面可以让级联的两个级联式硬盘的连接更加稳固,另一方面利用弹簧的弹力,能便于用户进行拆卸。
需要补充的是,本发明实施例提到的第一固定装置104和第二固定装置105不仅仅可以增强级联式硬盘10与其他级联式硬盘之间的作用力,还能够在更换级联式硬盘10时便于拆卸,实现了级联式硬盘10的单独更换。以级联式硬盘B的第一固定装置104为卡座结构,级联式硬盘A的第二固定装置105为卡槽结构为例,如图9所示,在更换级联式硬盘B时,沿卡座结构卡入卡槽结构的反方向用力(如图9中箭头所指示的方向),能够实现级联式硬盘A和级联式硬盘B的分离,从而实现级联式硬盘的单独更换。
基于上述实施例的描述,通过在级联式硬盘中设置用于与其他级联式硬盘级联的连接器,并通过级联式硬盘中设置的级联芯片实现级联式硬盘之间的数据交换,使得级联式硬盘之间可以互相相连,以形成级联式硬盘组,级联式硬盘组的容量相较于单个硬盘的容量大幅增长,实现了在不增加存储设备接口的情况下对存储设备的扩容。
本发明另一实施例以上述第一连接器200和上述第二连接器201均为SAS连接器,且以两个级联式硬盘采用方式二的连接方式达到紧密连接的效果为例,对本申请实施例提供的级联式硬盘进行具体介绍。如图10所示,本发明实施例提供一种级联式硬盘40、包含该级联式硬盘40的级联式硬盘模块4,所述级联式硬盘模块4还包括用于固定级联式硬盘40的连接结构件41。
其中,级联式硬盘40至少包括:第一SAS连接器400、硬盘主体403、第二SAS连接器401,以及与第一SAS连接器400、硬盘主体403和第二SAS连接器401均连接的级联芯片402。该级联式硬盘40的结构与图3所示的硬盘结构相同,在此不再赘述。
如图12所示,连接结构件41至少包括:连接主体411,以及设置在连接主体411上的第一连接件412和第二连接件413;第一连接件412,用于将级联式硬盘模块4固定连接至第一硬盘或存储设备;第二连接件413,用于与将级联式硬盘模块4固定连接至第二硬盘。
本发明实施例提供的级联式硬盘模块4,通过在级联式硬盘模块4包括的级联式硬盘10中设置与其他级联式硬盘级联的连接器,并通过级联式硬盘40中设置的级联芯片402实现级联式硬盘之间的数据交换,使得级联式硬盘模块4之间可以互相相连,以形成级联式硬盘组。并且,通过在连接结构件41上设置连接件,使得级联的两个级联式硬盘模块之间能够紧密连接。级联式硬盘组的容量相较于单个硬盘的容量大幅增长,实现了在不增加存储设备接口的情况下对存储设备的扩容。
进一步地,如图11所示,硬盘主体403(如图11中虚线所指示的部分)具体包括:与级联芯片402连接的控制芯片4030,与控制芯片4030连接的备电电容4031,与控制芯片4030和备电电容4031均连接的内存4032,以及与控制芯片4030连接的至少一个FLASH 4033。
需要说明的是,在本发明实施例中,连接结构件41主要的作用是固定级联式硬盘40,以及实现级联式硬盘模块之间的紧密连接,也就是说,能够起到固定作用及固定连接级联式硬盘作用的结构件均属于本发明实施例的所述的连接结构件41,本实施例中对连接结构件41的具体结构并不做限制。
为了便于理解,本发明实施例以一种结构示例对连接结构件41,以及连接结构件41与级联式硬盘40的固定连接进行介绍。如图12所示,级联式硬盘40还包括:设置在级联式硬盘40的外壳上的第一固定件404。连接结构件41还包括:设置在连接主体411上的第二固定件414,第一固定件404与第二固定件414固定连接,以将级联式硬盘40固定在连接结构件41上,使得级联式硬盘40与连接结构件41扣紧固定。其中,第一固定件404设置在级联式硬盘40外壳的与连接结构件41连接的一侧,第二固定件414设置在连接主体411的与级联式硬盘40连接的一侧。
具体的,第一固定件404和第二固定件414为配合使用的一对粘性结构,或者配合使用的一对磁性结构,或者配合使用的一对紧固件结构。
进一步地,若第一固定件404和第二固定件414为一对紧固件结构,第一固定件404可以为卡槽结构,相应的,第二固定件414可以为卡勾结构,或者,第一固定件404可以为卡勾结构,相应的,第二固定件414可以为卡槽结构。其中,卡勾结构能够卡入卡槽结构中。可选的,卡勾结构中还可以设置有簧片,以方便级联式硬盘40与连接结构件41的组装。
进一步地,如图12所示,连接结构件41还可以包括:设置在连接主体411上的引导件415,第二固定件414设置在引导件415上,级联式硬盘40在外力的推动下可延引导件415滑动,使第一固定件404与第二固定件414固定连接。示例性的,如图12所示,该引导件415为导槽。
例如,如图12所示,可以在外力的推动下将级联式硬盘40通过引导件415(导槽)在连接结构件41的连接主体411内部滑动,以便带簧片的第二固定件414(卡勾结构) 和第一固定件404(卡槽结构)扣紧固定,形成如图13所示的级联式硬盘模块4。
在本发明实施例中,以2个级联式硬盘模块级联为例,2个级联式硬盘模块的连接示意图如图14所示,为了便于描述,将图14中左方的级联式硬盘模块称为级联式硬盘模块A,将图14中右方的级联式硬盘模块称为级联式硬盘模块B,级联式硬盘模块A和级联式硬盘B级联后称为级联式硬盘组。可以看出,级联式硬盘模块A包括的连接结构件的第二连接件413与级联式硬盘模块B包括的连接结构件的第一连接件412连接,如,联式硬盘模块A包括的连接结构件的卡勾结构卡入级联式硬盘模块B包括的连接结构件的卡槽结构中。需要补充的是,本发明实施例中,为了方便单个级联式硬盘模块的更换,如图14所示,拉手条43可以单独组装。连接完成后,形成如图15所示的级联式硬盘组。
示例性的,级联式硬盘模块B的第一连接件412和级联式硬盘模块A的第二连接件413为配合使用的一对粘性结构,或者配合使用的一对磁性结构,或者配合使用的一对紧固件结构。

进一步地,卡槽结构中还可以设置有簧片,利用簧片的弹力,方便用户进行拆卸。
本发明另一实施例提供一种级联式硬盘的告警方法,该方法应用于存储设备中,存储设备中包括N个级联的具有上述任一特征的级联式硬盘,或者,存储设备中包括N个级联的具有上述任一特征的级联式硬盘模块,N为大于或者等于2的整数,如图16所示,该方法包括S101-S104:
S101、存储设备获取级联式硬盘组的被占用容量。
需要说明的是,级联硬盘组指的是N个级联式硬盘或级联式硬盘模块级联后的组成的硬盘组。本发明实施例中提到的被占用容量是指级联式硬盘组中的各个级联式硬盘的被占用容量之和。示例性的,若3个级联式硬盘(分别为级联式硬盘A、级联式硬盘B和级联式硬盘C)级联后,级联式硬盘A的被占用容量为20GB,级联式硬盘B的被占用容量为50GB,级联式硬盘C的被占用容量为0,那么,级联式硬盘组的被占用容量为70GB。
S102、存储设备判断被占用容量是否大于或者等于第一预设阈值。
S103、若被占用容量大于或者等于第一预设阈值,存储设备判断级联式硬盘组中发生故障的级联式硬盘的个数是否为第二预设阈值。
S104、若级联式硬盘组中发生故障的级联式硬盘的个数为第二预设阈值,存储设备发出告警,其中,第一预设阈值与第二预设阈值一一对应。
下面,对步骤S102、步骤S103和步骤S104进行详细说明:
当级联式硬盘组的被占用容量大于或者等于第一预设阈值,且级联式硬盘组中发生故障的级联式硬盘的个数为第二预设阈值时,说明此时级联式硬盘组无法满足当前工作的需要,因此存储设备能够发出告警,提醒用户对发生故障的级联式硬盘进行更换。
同时,本发明实施例所提到的告警可以为声音、光线、震动等能够引起用户注意的告警信息,还可以为以邮件、短信、弹窗等形式发送至用户使用的电子设备的告警信息,本发明对此不作具体限制。
需要说明的是,存储设备中能够设置不止一组预设阈值(即包括第一预设阈值,以 及与第一预设阈值对应的第二预设阈值)。在一种可能的实现方式中,存储设备中能够存储一个第一预设阈值和第二预设阈值的对应列表,如表1所示:
表1
第一预设阈值 | 第二预设阈值 |
100 | 5 |
200 | 4 |
…… | …… |
500 | 1 |
其中,第二预设阈值的取值为小于级联式硬盘级联个数N的正整数。
可以理解的是,上述在存储设备中存储一个第一预设阈值和第二预设阈值的对应列表的方案只是存储第一预设阈值和第二预设阈值对应关系的一种可实现的方式,其他能够体现第一预设阈值和第二预设阈值对应关系的方案同样属于本发明实施例的保护范
围,本发明对此不作具体限制。
示例性的,若N个级联式硬盘中每个级联式硬盘的可使用容量均为X,第一预设阈值为C*X,第二预设阈值为N-C,其中,C为大于或者等于1,且小于N的整数,如图17所示,步骤S102-S104可以包括S102a-S104a:
S102a、存储设备判断被占用容量是否大于或者等于C*X。
S103a、若被占用容量大于或者等于C*X,存储设备判断级联式硬盘组中发生故障的级联式硬盘的个数是否为N-C个。
S104a、若级联式硬盘组中发生故障的级联式硬盘的个数为N-C个,存储设备发出告警。
示例性的,以级联式硬盘组中包括的级联式硬盘的个数为3,每个级联式硬盘的可使用容量均为100GB为例进行说明,本发明实施例提供的级联式硬盘的告警方法中C可以取1或者2,即级联式硬盘的告警方法中可以包括两组第一预设阈值和第二预设阈值:第一组中的第一预设阈值为100GB,第二预设阈值为2;第二组中的第一预设阈值为200GB,第二预设阈值为1。
首先,存储设备判断被占用容量是否大于或者等于100GB,若被占用容量小于100GB,则存储设备不进行告警;若被占用容量大于或者等于100GB,则存储设备判断级联式硬盘组中发生故障的级联式硬盘的个数是否为2个。若此时存储设备判断级联式硬盘组中发生故障的级联式硬盘的个数为1个或者0个,则存储设备不进行告警;若此时存储设备判断级联式硬盘组中发生故障的级联式硬盘的个数为2个,则说明此时级联式硬盘组无法满足当前工作的需要,因此存储设备发出告警。
随后,存储设备判断被占用容量是否大于或者等于200GB,若被占用容量大于或者等于200GB,则存储设备判断级联式硬盘组中发生故障的级联式硬盘的个数是否为1个。若此时存储设备判断级联式硬盘组中发生故障的级联式硬盘的个数为0个,则存储设备不进行告警;若此时存储设备判断级联式硬盘组中发生故障的级联式硬盘的个数为1个,则说明此时级联式硬盘组无法满足当前工作的需要,因此存储设备发出告警。
进一步地,该方法还可以包括S105和S106:
S105、存储设备判断级联式硬盘组中发生故障的级联式硬盘的个数是否为N个。
S106、若级联式硬盘组中发生故障的级联式硬盘的个数为N个,存储设备发出告警。
当级联式硬盘组中所有的级联式硬盘均发生故障,则存储设备直接发出告警,以提醒用户对级联式硬盘进行更换。
本发明实施例提供一种级联式硬盘的告警方法,应用于存储设备,存储设备中包括N个级联的具有上述任一特征的级联式硬盘,N为大于或者等于2的整数,级联式硬盘的告警方法包括:存储设备获取级联式硬盘组的被占用容量;在存储设备确定被占用容量大于或者等于第一预设阈值,且级联式硬盘组中发生故障的级联式硬盘的个数为第二预设阈值时,存储设备发出告警,其中,第一预设阈值与第二预设阈值一一对应。基于上述实施例的描述,存储设备通过在确定被占用容量大于或者等于第一预设阈值,且级联式硬盘组中发生故障的级联式硬盘的个数为第二预设阈值时发出告警信息,提醒用户对发生故障的级联式硬盘进行更换。同时,由于级联式硬盘之间是通过第一固定装置和第二固定装置将一个级联式硬盘的第一SAS连接器和另一个级联式硬盘的第二SAS连接器连接起来的,用户在更换级联式硬盘时能够很方便地拆卸,实现了级联式硬盘的单独更换,减少了维护的工作量。
本发明实施例还提供一种存储设备,该存储设备用于执行以上级联式硬盘的告警方法中的存储设备所执行的步骤。本发明实施例提供的存储设备可以包括相应步骤所对应的模块。
本发明实施例可以根据上述方法示例对存储设备进行功能模块的划分,例如,可以对应各个功能划分各个功能模块,也可以将两个或两个以上的功能集成在一个功能模块中。上述集成的模块既可以采用硬件的形式实现,也可以采用软件功能模块的形式实现。本发明实施例中对模块的划分时示意性的,仅仅为一种逻辑功能划分,实际实现时可以有另外的划分方式。
如图18所示,该存储设备包括:通信接口30、处理器31和存储器32。其中,通信接口30、处理器31与存储器32之间通过系统总线33连接,并完成相互间通信。
