你真的懂存储系统么？
在这个数据横行的时代，每个人的生活已经离不开数据信息。财富变成支付宝上的一串数字，一张身份证和一部手机就能行走天下，是因为我们能够随时随地取用数据属于我们自己的数据。那么，对于数据来说，存储系统的重要性不言而喻。一方面要考虑的是数据存储的安全性，一方面又由于大数据时代数据需要实时进行海量处理与传输，所以存储系统的好坏直接决定了信息的“质量”。
对于存储系统的理解，一般分为狭义的存储系统与广义的存储系统。
“狭义的存储系统”一般就是人们普遍认知中的存储介质，例如光盘，U盘，闪存卡等。这些是存储必不可少的组件，
每种介质都可以在不同的应用场景下发挥出价值。之所以说是“狭义的”，主要是由于的存储大多应用于信息系统。而对于一个完整的信息系统来说，存储系统作为其中的一个关键模块，不仅仅需要有存储介质，这就是我们所说的“广义的存储系统”。
“广义的存储系统”的结构主要由以下几个组件组成，分别是存储硬件，存储软件，存储解决方案。接下来详细介绍一下，首先，存储硬件就是我们用于数据中心的存储阵列，网络设备（用于SAN）等，主要作为底层的硬件设施；其次，存储软件包含管理软件，高级特性软件，备份软件，多路径软件等，主要用于实现管理以及一些高级应用特性的实现，例如快照，分级存储和备份等；最后，存储解决方案主要在硬件软件的基础之上，针对不同应用场景推出的不同解决方案，可以是容灾解决方案，备份解决方案等。这样才组成了一个完整的存储系统，用于大型的数据中心的信息系统中！
现如今大数据应用广泛，存储对于大数据来说，是不可或缺的一个部分。大数据中的存储系统主要负责海量数据的存储及传输，所以未来存储系统的发展方向不仅要能提供存储的灵活扩展性，也需要能够快速装载数据。结合当下各大厂商的存储产品趋势，未来存储系统上层能够承载的业务会越来越多，现如今已能够同时提供块存储，文件存储，对象存储等。所以，未来存储系统还有非常多的发展可能性，为我们创造更加便利的世界！
