福建夭滋家庭服务有限公司_了解存储:块、文件和对象

????编译自:https://www.linux.com/blog/2018/9/know-your-storage-block-file-object author:swapnil bhartiya translator:qhwdw今天生成的海量数据带来了新的存储挑战。在本文中,我们将了解各种存储类型以及如何使用它们。现在,对于创建或消费数据的公司来说,处理大量生成的数据是一个巨大的挑战。对于解决存储相关问题的技术公司来说,这也是一个挑战。Red Hat Storage的首席产品营销经理Michael St.Jean说:“数据每年都以几何形式增长,我们发现这种增长的主要原因是消费的增长和产业转型以扩大价值。毫无疑问,物联网对数据增长的贡献很大,但软件定义存储最重要的挑战是如何处理用户场景。相关数据增长。”任何挑战都意味着机遇。Azure存储、媒体和边缘计算总经理Tad Brockway说:“今天,新老数据源生成的大量数据为我们提供了一个机会,以满足客户在规模、性能、灵活性和治理方面快速增长的需求。”现代软件定义了三种存储类型。有三种不同类型的存储解决方案——块、文件和对象——每个解决方案都可以与其他解决方案一起使用,但每个解决方案都有不同的用途。块存储是最古老的数据存储形式,数据存储在固定长度的块或块中。块存储适用于企业存储环境,通常使用光纤通道或iSCSI接口。根据SuSE定义的存储高级产品经理Larry Morris的说法,“块存储需要一个应用程序来映射存储设备上存储的数据块的位置。”块存储在存储区域网络和软件定义的存储系统中是虚拟的。它是共享硬件基础结构上的抽象逻辑设备。它是基于诸如SCSI、SATA、SAS、FCP、FCoE或iSCSI等协议在服务器、虚拟服务器或系统管理程序上创建和存在的。St.Jean说,“块存储将单个卷(如虚拟或云存储节点,或旧硬盘)划分为称为块的单独实体。”每个块都独立存在,并且可以使用自己的数据传输协议和操作系统进行格式化,给用户完全的配置自主权。块存储系统是一个非常快速的存储系统,因为它不像文件存储系统那样负责文件查找。由于速度和配置的灵活性,块存储非常适合于原始服务器存储或富媒体数据库。块存储适用于主机操作系统、应用程序、数据库、完整的虚拟机和容器。传统上,块存储只能由独立的机器访问,也只能呈现给集群中的机器。基于文件的存储基于文件的存储使用文件系统来映射存储设备上数据的存储位置。该技术在直接连接或网络附加存储系统的应用领域中占有主导地位。它需要做两件事:组织数据并将其呈现给用户。圣琼说:“当使用文件存储时,数据在服务器端的存储方式与客户机用户看到的完全相同。这允许用户通过一些唯一的标识符(如文件名、位置或URL)请求文件,并使用特定的数据传输协议与存储系统进行通信。其结果是一个分层的文件结构,可以从上到下浏览。文件存储位于块存储之上,允许用户查看和访问文件和文件夹等数据,但对这些文件和文件夹下的数据块的访问受到限制。Brockway解释说,“文件存储通常用于共享文件系统,许多服务器(如NFS和CIFS/SMB)通过IP网络进行访问。访问控制是在具有用户和组权限的文件、目录和导出级别上实现的。基于文件的存储可用于存储多个用户和计算机、二进制应用程序、数据库、虚拟机和容器所需的文件。对象存储对象存储是数据存储的最新形式。它为非结构化数据提供了一个仓库。它将内容与索引分离,并允许多个文件连接到一个对象。对象是与任何相关元数据配对的数据块,这些元数据提供对象中包含的字节的上下文(如数据创建时间和数据大小)。也就是说,这两件事——数据和元数据——构成了一个对象。对象存储的一个优点是,每个数据块都与一个唯一的标识符相关联。访问数据需要唯一的标识符,并且不需要应用程序或用户知道数据实际存储在哪里。对象数据通过API访问。圣琼说:“存储在对象中的数据没有被压缩和加密,对象本身被组织在对象存储(一个包含其他对象的中央库)或容器(一个包含应用程序运行所需的所有文件的包)中。”与文件存储系统的层次结构相比,对象、对象存储和容器基本上是平的,这使得它们在存储空间较大时访问速度更快。“对象存储可以扩展到许多PB字节大小以容纳大型数据集,因此它是用于图像、音频、视频、日志、备份的数据存储的最佳选择,和分析服务。结论是,您现在知道了各种存储及其用途。稍后,我们将继续对这个主题进行更多的研究。请注意。作者:https://www.linux.com/blog/2018/9/know-your-storage-block-file-object作者:swapnil bhartiya selection:lujun 9972翻译器:qhwdw校对:wxy本文最初由lctt编译,linux china荣誉发布点击“know more”访问本文中的链接。
