Grid Storage
Definition: Grid storage, analogous to grid computing, is a new model for deploying and managing storage distributed across multiple systems and networks, making efficient use of available storage capacity without requiring a large, centralized switching system.
网格存储类似于网格计算，在多道系统和网络中进行分布式存储管理的一个新的模型。能够高效的利用存储资源而不需要一个大的中央交换系统 A grid is, in fact, a meshed network in which no single centralized switch or hub controls routing. Grids offer almost unlimited scalability in size and performance because they aren't constrained by the need for ever-larger central switches. Grid networks thus reduce component costs and produce a reliable and resilient structure.
网格实际上是一种格状网，没有单个的中央交换机来控制路由。网格几乎在大小和行为上没有现在。不会受交换机需求的现在。格状网能够降低消费
Applying the grid concept to a computer network lets us harness available but unused reso
urces by dynamically allocating and deallocating capacity, bandwidth and processing among numerous distributed computers. A computing grid can span locations, organizations, machine architectures and software boundaries, offering power, collaboration and information access to connected users. Universities and research facilities are using grids to build what amounts to supercomputer capability from PCs, Macintoshes and Linux boxes.
将网格的概念应用到计算机网络让我们通过动态分配资源使得资源的利用率更高。这些资源分布在多台分布式计算机撒谎那个，包括存储空间，带宽等等。网格计算提供用户交互和资源的访问。大学和很多研究设备正使用网格来构建一个超机计算机。
After grid computing came into being, it was only a matter of time before a similar model would emerge for making use of distributed data storage. Most storage networks are built in star configurations, where all servers and storage devices are connected to a single central switch. In contrast, grid topology is built with a network of interconnected smaller switches that can scale as bandwidth increases and continue to deliver improved reliability and higher performance and connectivity.
分布式数据存储。网格拓扑结构建立在由许多互联的小交换机网上。能够平衡带宽增长和继续提高可靠性、靠性能，以及连通性。 What Is Grid Storage?
Based on current and proposed products, it appears that a grid storage system should include the following:
网格存储系统应该包含以下几个方面。
投资区域Modular storage arrays: These systems are connected across a storage network using serial ATA disks. The systems can be block-oriented storage arrays or network-attached storage gateways and servers.
1、微型存储阵列：这些系统连接在由ATA磁盘阵列组成的交叉存储网络上。面向块存储或网关和服务器
Common virtualization layer: Storage must be organized as a single logical pool of resources available to users.
2、通用虚拟层：存储必须组成一个用户可用资源的逻辑池。
Data redundancy and availability: Multiple copies of data should exist across nodes in the grid, creating redundant data access and availability in case of a component failure.

Common management: A single level of management across all nodes should cover the areas of data security, mobility and migration, capacity on demand, and provisioning.
4、通用数据管理：这个管理需覆盖所有交叉节点上数据的安全性，可移植性，存储空间需求。

Simplified platform/management architecture: Because common management is so important, the tasks involved in administration should be organized in modular fashion, allowing the auto discovery of new nodes in the grid and automating volume and file management.rfq
5、简单的平台/管理结构：由于通用管理非常重要，定义一种标准的管理方式来管理数据。

Three Basic Benefits
Applying grid topology to a storage network provides several benefits, including the following:
将网格拓扑结构应用到网格存储上有以下好处：
Reliability. A well-designed grid network is extremely resilient. Rather than providing just two paths between any two nodes, the grid offers multiple paths between each storage node. This makes it easy to service and replace components in case of failure, with minimal impact on system availability or downtime.
1、可靠性方面：网格给每个存储节点提供多个路径。使得很容易提供服务以及在组建出错后的数据恢复。
Performance. The same factors that lead to reliability also can improve performance. Not requiring a centralized switch with many ports eliminates a potential performance bottleneck, and applying load-balancing techniques to the multiple paths available offers consistent performance for the entire network.
2、性能方面：不仅能提高可靠性还能提高性能。不需要中央交换机。并且对多个存储路径应用负载平衡技术，为整个网络提供始终如一的高性能。
Scalability. It's easy to expand a grid network using inexpensive switches with low port counts to accommodate additional servers for increased performance, bandwidth and capacity. In essence, grid storage is a way to scale out rather than up, using relatively inexpensive storage building blocks.
3、扩展性方面：很容易通过使用廉价的交换机来扩展网络。实际上使用廉价的存储块。
