The metal might consist of RAM or hard disks, but in either case, file system data structures organize the sectors and bytes formatted by the hardware manufacturer.
原始材料可能由RAM或硬盘组成，但是不管是哪种情况，文件系统数据结构都是组织由硬件制造商格式化了的扇区和字节。
The same test was run using a RAM disk file system to show the difference in speed.
此外，使用RAM磁盘文件系统再次运行了这个测试，以显示速度方面的差异。
Keep in mind that these file systems as well as the kernel are stored in RAM initially during the operating system boot process.
请记住，在操作系统启动过程中，这些文件系统以及内核最初是存储在内存中的。
In a well-tuned site, this disk offload file fits entirely into the file system cache, and is served out of RAM.
在一个优化的网站上，这个磁盘卸载文件会完全存储在文件系统缓存中，它位于RAM之外。
In a nutshell, the kernel is booted as normal; but instead of mounting the "real" root file system, a miniature root filesystem is created in RAM, and that is mounted.
简而言之，内核像平常一样引导；但不安装“真实的”根文件系统，而是在RAM中创建微型根文件系统并安装该系统。
Past documentation has indicated the need for the fastest logging disks possible, so we reran the tests using a RAM disk file system, to see if doing so made a difference.
过去的文档表明需要使用最快的日志磁盘，所以我们使用RAM文件系统重新运行测试，看看结果是否有差别。
The initial RAM disk was originally created to support bridging the kernel to the ultimate root file system through a transient root file system.
初始ram磁盘最初是设计用来通过一个临时根文件系统来作为内核到最终的根文件系统之间的桥梁。
A little used and relatively new feature is the RAM disk, which allows for the use of physical RAM as the storage for a file system.
一个不常用并且较新的特性是RAM磁盘，它允许使用物理ram存储文件系统。
RAM disk root file system (ramdisk.gz)
RAM磁盘根文件系统（ramdisk.gz）
Now that you've seen how to build and use a custom initial RAM disk, this section explores how the kernel identifies and mounts the initrd as its root file system.
现在我们已经了解了如何构建并使用定制的初始ram磁盘，本节将探索内核是如何识别initrd并将其作为根文件系统进行挂载的。
This initrd serves as a temporary root file system in RAM and allows the kernel to fully boot without having to mount any physical disks.
这个initrd 会作为RAM中的临时根文件系统使用，并允许内核在没有挂载任何物理磁盘的情况下完整地实现引导。
The initrd is also useful as a non-persistent root file system mounted in a RAM disk for embedded Linux systems.
initrd对于在嵌入式系统中加载到RAM磁盘里的非持久性根文件系统来说也非常有用。
The initrd image is actually a RAM disk that contains a small file system with basic configuration files, binaries, libraries, and drivers.
initrd映像实际上是一个RAM磁盘，其中包含带有基本配置文件、二进制文件、库和驱动程序的小型文件系统。
Using bosboot, you create a boot file (that is, a bootable image) from a RAM disk, a file system, and a kernel.
使用bosboot命令可以从ram磁盘、文件系统或内核创建启动文件(即可启动映像)。
The initial RAM disk (initrd) is an initial root file system that is mounted prior to when the real root file system is available.
初始ram磁盘(initrd)是在实际根文件系统可用之前挂载到系统中的一个初始根文件系统。
A file system (perhaps in ROM or RAM).
一个文件系统(可能是在ROM或者是ram里)。
When set to 0 ( Default ) a standard sized file system cache is allocated (Less than 10MB RAM); this is recommended as it provides best Application performance.
当设置为0（默认）标准大小的文件系统缓存分配（少于10MB的内存），这是推荐的。
System performance may be improved by reducing the amount of RAM that file pages occupy - this ensures that working pages are not continually being pushed out to make way for file pages.
系统性能可能被通过减少文件页来得到提高，这样可以保证工作页不会被连续给文件页强占位置。
