LUN-level switching is only available when using the DS8000 storage server and can switch the IASP between partitions or between systems.
LUN - level切换技术只有在使用DS8000存储服务器环境下才能采用，它可以在分区间或在系统间切换IASP。
Switched disk and LUN-level switching use only one copy of the IASP but can switch the connection of that IASP from one system to another.
交换磁盘和LUN - level切换仅使用一份IASP副本，就可以把IASP的连接从一个系统切换到另一个系统。
Typically, clients use switched disk or LUN-level switching within a data center to provide local protection from planned and unplanned outages not involving the disk subsystem.
客户通常会在数据中心使用交换磁盘或 LUN-level 技术来为计划内和计划外中断提供本地保护，但不涉及到磁盘子系统。
This paper proposes a design scheme on multi-level switching. We provide a detail analysis about the defects of inherent signal crosstalk existing in Matrix system.
文中对矩阵系统所存在的固有的信号串扰缺陷进行了比较详尽的分析，提出了多级切换的设计方案。
