- 什么是SDS
SDS是一个数据存储管理解决方案，它将底层物理硬件与存储功能软件分开处理，使软件功能脱离对硬件的绑定，并提供删重，精简配置，快照，备份等功能。
SDS的特色：
1.将物理存储抽象为逻辑存储,包括：Storage Virtualization，Virtual volumes，pNFS, OpenStack Swift、Cepf等存储接口，部分对象存储平台，部分分布式存储solution。
2.策略驱动的自动化
3.a clustered file system for converged storage
SDS应该包括如下功能:
- 自动化 Automation– Simplified management that reduces the cost of maintaining the storage infrastructure.
- 标准接口 Standard Interfaces –APIs for the management, provisioning and maintenance of storage devices and services.
- 虚拟数据路径 Virtualized Data Path – Block, File and Object interfaces that support applications written to these interfaces.
- 扩展性 Scalability – Seamless ability to scale the storage infrastructure without disruption to availability or performance.
- 透明性Transparency – The ability for storage consumers to monitor and manage their own storage consumption against available resources and costs.

- SDS类型：
- Hypervisor-based
- Container-based (for example, running in a Docker container)
- Scale-out storage for unstructured data
- Distributed file systems for object storage offload
- HCI software(storage is combined with networking, compute, and virtualization software in the same package)
