Therefore, by using these workloads, you can get more realistic information (CPU, disk, memory, and network) for deployment planning than with prior workloads.
并且由于信息是从ram而不是通过数据库和其他处理从磁盘加载的，所以对信息的访问几乎是瞬时的。
And because the information is being loaded from RAM, and not from disk through a database and other processing, the access to the information is almost instantaneous.
在磁盘上，超块向内核提供关于磁盘上的文件系统的结构的信息。
On disk, the superblock provides information to the kernel on the structure of the file system on disk.
OAT提供DBA所需的大量信息，比如磁盘空间使用情况、日志文件、消耗IO时间最多的sql语句、最慢的sql语句等等。
The OAT provides the much needed information required by the DBA like the disk space usage, log files, SQL statements occupying the most IO time, the slowest SQL statements, and so on.
由于该接口在所有设备中保持一致，您可以跨多个主机使用相同方法来获取正常运行时间、网络统计数据、磁盘空间甚至进程监视信息。
Because the interface is consistent across all the devices, you can get uptime, network statistics, disk space, and even process monitoring using the same methods across multiple hosts.
读任何磁盘上MBR给我们提供了所有启动系统的信息。
Reading any which MBR on either disk provides us with the whole set of information required to boot the system.
它显示磁盘统计数据，可以表明一个硬件磁盘是否负担过重，对于这种情况，可以通过把文件系统或信息分散到其他磁盘上加以改善。
It shows disk statistics and can show you if a single hardware disk is being hammered and would benefit from having filesystems or information spread and moved over other disks.
但是缓冲区尺寸小造成它不适合更大数量的日志信息，而且记录的信息不能保存到磁盘也使得难以分析一段时间内的性能。
But the small buffer size makes it unsuitable for larger quantities of log information, and the logged information isn't stored to disk so it's hard to analyze over a period of time.
此界面显示了关于系统的部分信息，如磁盘上剩余可用空间和磁盘的总空间。
This interface shows some information about your system, such as the amount of free space left in the disk and the size of your disk.

Larger disks containing several gigabytes of information will be standard, and terabyte storage — roughly the capacity of the Library of Congress — will be common.
第二个命令显示磁盘I/O信息，并有助于确定是否需要增加AIO/KAIO虚拟处理器。
The second command is to display disk I/O information and is helpful in determining whether we need to increase AIO/KAIO virtual processors. Here is the eample
再强调一下，memcached是一个用来存储常用信息的缓存，有了它，您便无需从缓慢的资源，比如磁盘或数据库，加载并处理信息了。
To reiterate, memcached is a cache for storing frequently used information to save you from loading and processing information from slower sources, such as disks or a database.
du命令并不是显示磁盘的空闲空间，而是显示磁盘使用情况的信息。
The du command, instead of showing disk free space, shows disk usage information.
vmstat 可以报告许多信息，包括内核线程、CPU活动、虚拟内存、分页、阻塞的I/O磁盘、以及相关信息（请参见清单3）。
