SSDs shine really bright when random I/Os are being executed.
但在执行随机I/O 操作时，SSD的确更胜一筹。
This can improve the parallelism of some I/Os.
这可以提高某些I/O 的并行性。
Non-prefetch I/Os are scheduled directly from the database agents and as a result are not constrained by NUM_IOSERVERS.
由于从数据库代理程序直接调度非预取I/O，因此非预取 I/O不受 NUM_IOSERVERS 约束。
Other graphs can be selected to show the total number of I/Os performed per second which will also indicate the improvement from SSDs.
还可以选择其他曲线图来显示每秒执行的I/O总量，这也能体现通过 SSD 实现的改进。
There may be more CPU usage and getpage operations, as well as more index page read and write I/Os.
可能需要使用更多的CPU 时间和getpage操作，以及更多的索引读取和写入I/O。
Since there are no moving parts in SSDs, and any part of the memory can be read instantaneously, the number of I/Os which can be performed is also extremely higher on SSDs.
由于SSD中没有移动部件，内存中的任何部分都可以瞬时读取，SSD 上可以执行的I/O数量也非常高。
Redo Logfile Sizing Advisor - This feature recommends the optimal size of redo log files in order to avoid excessive disk I/Os due to frequent checkpointing.
RedoLogfile SizingAdvisor ——此特性推荐重做日志文件的最佳大小，从而避免因频繁出现的检查点而导致过多的磁盘I/O。
Compared with symmetry interconnection architecture, this architecture can provide more flexible interconnection traces and I/Os, and support more I/O standards.
与现有的对称互连结构相比，该结构能提供更多的互连通道，可实现对I／O数量、电平类型和互连路径的灵活配置。
