您甚至可以使用AIXLVM将其迁移到一个全新的SAN存储子系统(请参阅参考资料)。
You can even use the AIX LVM to migrate to a completely new SAN storage subsystem (see Resources).
因为现存的存储上不存在任何底层文件系统或数据，所以在后端存储子系统上进行分配只需要几秒种。
Since there is no underlying file system or data on the presented storage, it takes mere seconds to allocate on the back-end storage subsystems.
数字图书馆拥有大量重要的数字资源，如何保障数据的安全，提高存储子系统的处理能力显得尤为重要。
There are lots of important digital resources in the digital library. It is very significant to guarantee the data safe and increase the ability of treatment of storage system.

快照技术是产生在线热备份的重要技术手段，存储子系统中使用快照技术能够有效地缩短复制操作造成的停机时间。
Snapshot is a major technology for online hot backup, it can effectively reduce the down-time needed to perform conventional copy operations in the storage subsystem.
当前主流的存储子系统快照技术主要侧重于在单一的时间点实现快照，而实际的应用经常需要实现连续时间点的快照。
Currently most common snapshot technologies focus on implementing snapshot at a single time point, but many applications need sequential points snapshot.
在本文中，我将与您分享一些示例以展示我是如何将AIX系统从旧的SAN存储子系统迁移到新的SAN存储子系统的。
In this article, I will share some examples of how I migrated AIX systems from old to new SAN storage subsystems.
几年前，我曾需要将大量的AIX主机从一个旧的IBMESS (F20)迁移到一个崭新的IBM DS8300存储子系统。
Several years ago I needed to migrate a large number of AIX hosts from an old IBM ESS (F20) to a shiny, new IBM DS8300 storage subsystem.
需要在存储子系统上执行适当的SANzoning、LUNmasking或映射，让相同的LUN对于两个VIOS分区都可用。
Any SAN zoning, LUN masking, or mapping that needs to be done on the storage subsystem needs to be done to make the same LUNs available to both the VIOS partitions.
如果您使用AIX的时间足够长，就会遇到需要将一个现有的AIX系统从旧的SAN存储设备迁移到崭新的SAN存储子系统的情况。
If you work with AIX long enough, a time will come when you will need to migrate an existing AIX system from an old SAN storage device to a shiny, new SAN storage subsystem.
一种改进的基于闪速EEPROM存储器的存储子系统，包括一个或多个闪存阵列，每一个都带有两个数据寄存器和一个控制器电路。
An improved flash EEPROM memory-based storage subsystem includes one or more flash memory arrays, each with a duplicity of data registers and a controller circuit.
解决这个问题的一种方法是使用全冗余路径来访问外部SAN(存储区域网)设备—通过这种方式，可以减少因存储子系统访问问题导致的故障。
One way to counter this is by using a fully redundant path to access external SAN (storage area network) devices-in this way, you can reduce failures caused by storage subsystem access problems.
运行结果表明，此存储子系统不仅很好地满足了标准清晰度电视无压缩数字播放系统的要求，而且也可满足高清晰度电视数字播放系统的要求。
The operation results indicate that the storage subsystem can satisfy not only the demand of the uncompressed digital playing system for SDTV, but also the dem…
操作系统的虚拟内存子系统允许应用程序分配的内存超过系统上实际存在的内存量，不足的部分由磁盘上的临时存储组成。
The operating system's virtual memory subsystem allows applications to allocate more memory than actually exists on the system, with the shortage being made up by temporary storage on disk.
文件的结构和大小取决于底层文件系统 —即把文件数据存储到物理设备上的子系统。
The structure and size of a file depends on the underlying file system—the subsystem that persists the file data to a physical device.
tmpfs还使用磁盘交换空间来存储，并且当为存储文件而请求页面时，使用虚拟内存(VM)子系统。
Tmpfs also makes use of the disk swap space for storage, and of the virtual memory (VM) subsystem when requesting pages for storing files.
