Making application highly available is not sufficient; we should also make the disk data highly available to achieve complete high availability.
仅仅实现应用程序的高可用性是不够的，我们还应该使磁盘数据高度可用，从而实现完整的高可用性。
As will be discussed later, the application talks only to the cache, and the cache talks to the disk.

The data gets copied multiple times among the disk, kernel buffer, and user buffer before it is finally delivered to the application.
数据在被最终传入到应用程序前，在磁盘、内核缓冲区和用户缓冲区中被拷贝了多次。
Persistent preallocation If an application needs to allocate disk space before actually using it, most file systems do so by writing 0s to the not-yet-used disk space.
持久性预分配如果一个应用程序需要在实际使用磁盘空间之前对它进行分配，大部分文件系统都是通过向未使用的磁盘空间写入0来实现分配。
A key part of this process is to map the requirements of the application model (operating system, architecture, disk, memory) to parts provided by plug-ins.
该流程的一个重要部分是将应用程序模型的要求(操作系统、架构、磁盘、内存)映射到插件提供的组件。
Choosing the total number and size of primary logs to be created is a tradeoff between disk space available and the ability of the application to endure the log's full situation.
选择要创建的主日志的总数和大小时，需要在可用磁盘空间和应用程序的功能之间进行折中，以便适应日志的所有情况。
Disk activity can be due to swapping, described earlier, or it can be due to requests from the application or operating system.
磁盘活动可能源于交换，也可能源于应用程序或操作系统的请求。
A root cause for this type of problem within Ajax applications has to do with how an Ajax application handles memory, disk space, and other system resources.
Ajax应用程序内这类问题发生的根本原因与Ajax应用程序如何处理内存、磁盘空间和其他系统资源不无关系。
In the sample application, the items array stores the title as NSString objects; therefore, it can be cached to disk in the application.
在应用程序示例中，条目数组将标题保存为NSString对象；因此，它能在应用程序中被缓存到磁盘上。
These organisations might also be concerned by the large disk and memory footprints that frameworks like Spring add to every application in which they are included.
这些组织可能也担心Spring这样的框架给其所在的每个应用程序带来的大量磁盘和内存占用。
As will be discussed later, the application talks to both the side cache and the disk.
正如后文所讨论的，应用程序可以与sidecache和磁盘对话。
The dashboard always gives you the current CPU, RAM, swap, and disk usage, and shows this relative to the allocations you've configured for your application (see figure 6).
这个指示板显示当前的CUP、RAM、交换和磁盘使用信息，以及您为应用程序配置的资源分配(见图6)。
Jungle Disk is great at backup, but you can also use it with any application you'd like that can write to a network drive.
JungleDisk的备份功能很强，还可以与其它读写网络驱动器的应用程序同时协作。
Use this agent to specify a list of raw disk devices, and reserve all or a percentage of accessible disks for an application.
使用这个agent指定一个空磁盘设备列表，并为某个应用预订全部或一定百分比的可用磁盘。
On the primary site, an application workload can now run against the database, and the Metro mirror function automatically mirrors changes at the disk level to the target site.
在主站点上，应用程序工作负载现在可以针对此数据库运行，并且MetroMirror函数会自动将磁盘级别的更改镜像到目标站点。
Used to set optional properties on a cache entry, such as whether it can be cached outside of WebSphere Application Server, and whether this entry can be persisted to disk.
