SAN (storage area network )
定义：
Storage area network (SAN) is a network that primarily connects the storage systems with the computer systems and also connects the storage systems with each other
解释：
·一种网络
·连接存储与主机，存储与存储
SAN, LAN 还有WAN构建了我们的网络系统
vSAN (virtual SAN)
定义：
A logical fabric on an FC SAN, enabling communication among a group of nodes, regardless of their physical location in the fabric.
解释：
·一种网络
·虚拟的网络（虚拟化的特点就是尽可能地脱离物理资源的限制）
·在一个物理SAN上可以画出多个vSAN.
·在跨物理SAN的元件可以画入同一vSAN中
vSAN storage
（有时候直接称为vSAN, 有的解释为irtual SAN，还可以解释为VMware SAN, 但是为了更加容易区别，还是把它称为vSAN storage或vSAN database）
定义：
is a software-defined storage offering from VMware that enables enterprises to pool their storage capabilities and to instantly and automatically provision virtual machine storage via simple policies that are driven by the virtual machine.
解释：
·一种存储
·软件定义的存储
·由VMware提出
·作用是将物理的存储池化
·好处是能更加灵活地运用存储(扩容，分配，管理等)
