physical I-O

However, one of the known limitations of the test environment was that it had less than ideal I/O capacity (due to a limited number of physical spindles).

然而，这个测试环境的一个已知限制是它的 I/O 容量不够理想（原因是物理转轴数量有限）。

These statistics are useful to adapt system configuration to balance the I/O between physical disks and adapters.

对于调整系统配置以便在物理磁盘和适配器之间平衡 I/O 来说，这些统计信息是非常有价值的。

This physical I/O channel configuration make multipath SAN possible at the physical layer.

这个物理 I/O 通道配置在物理水平让多路径 SAN 成为可能。
