摘要
存储的传统底层RAID技术自商用以来已经有30年时间了,但随着数据量的增大和单盘片容量的扩大,原有RAID技术问题越来越明显。由此提出了新的底层RAID技术——块级虚拟化技术,将单盘片重新规划,抽象了存储的真实物理地址,在软件层面上,它解析逻辑IO请求,将其映射成正确的物理地址。这种架构的创新,使存储性能和安全性得到大幅提升。
The lraditional underlying RAID technology has been 30 years, but with the increasing amount of data and the expansion of single disc capacity, the problems of original RAID technology become more and more apparent. New underlying RAID technology, namely block-level virtualization technology, is proposed, which will replan single disc and abstract the real physical address. It can analyze logic IO request and map it into the correct physical address using software. The innovation of this architecture greatly improves the storage performance and the security.
