SAN是否真的需要进行碎片整理。如果是这样，保持***性能的***方法是什么？

Is it true that a SAN does not need to be defragmented. If so what is the best way to keep peak performance?

不，SAN 需要进行碎片整理。

No, a SAN does needs to be defragmented.

许多SAN供应商提供的工具可以优化 SAN环境，但物理磁盘是SAN基于未解决 - 需要单独进行碎片整理。

Many SAN vendors provide tools with which to optimize the SAN enveironment, but the physical disks that the SAN is based on are not addressed -- these need to be defragmented separately.

碎片整理需要正确配置SAN，以确保整个系统（包括SAN所基于的物理磁盘）的最大性能提升，因为不正确的碎片整理可能会阻碍SAN运行。

The defrag of a SAN needs to be properly configured to ensure maximum performance gain for the entire system including the physical disks the SAN is based on, as improper defrag may hinder SAN operations.

制作东西更简单的是，Diskeeper为SAN连接的服务器提供了预先配置的Diskeeper。在这里了解它：
