如果请求的变化很大，导致无法有效地使用操作系统的磁盘缓存，那么服务器的磁盘会很忙，到了某种程度之后，就会减慢整个过程。
If the requests are varied enough to make ineffective use of the operating system's disk cache, then the server's disks will become busy and at some point slow the whole process down.
首先，在NFS服务器上配置磁盘配额。
物理服务器：每个租户需要专用的服务器、磁盘空间和辅助设备。

完成这些步骤之后，SAN上的Linux将设置为主要的候选磁盘，在服务器电源打开和通过自检运行时将从这里启动。
After doing these steps, Linux on the SAN will be set as the primary candidate disk for booting up when the server powers on and runs through its self check.
创建VIO服务器磁盘资源。
步骤5：准备HDR备用服务器的磁盘。
如您所见，磁盘标签告诉服务器您的文件映像是sda1设备。
As you can see, the disk label tells the servers that your file image is a sda1 device.
该模式下，当日志数据存在于主服务器的磁盘上，且备用服务器已经收到了日志数据时，提交(commit)就成功了。
In this mode, a commit succeeds when the log data is on disk at the primary and it has been received by the standby server.
用于Linux分区的虚拟磁盘称作网络服务器存储空间(NWSSTG)。
The virtual disk for a Linux partition is called a Network Server Storage Space (NWSSTG).
DB 2服务器磁盘空间需求。
为p5服务器上配置的两个VIO服务器分配SAN磁盘。
Allocate the SAN disks to both of the VIO Servers configured on the p5 server.
可以使用Blade 中的内部磁盘驻留VIO服务器，也可以选择用SAN引导 Blade，因为也支持这种方式。
The internal disk within the Blade can be used to house the VIO server or you may choose to boot the Blade with the SAN, as this is also supported.
这样一来，若任何一个服务器故障，另一个服务器都能立即作为主服务器从故障的服务器接管磁盘。
This way, should one of the servers fail, the other server can take over as primary for the disks from the failed server.
但对于在磁盘或服务器崩溃后有用的数据，必须存储在另外一台服务器上。
But for this data to be useful after a disk or server crash, it must be stored on another server.
主服务器拥有对一个磁盘或磁盘阵列的写访问权，而所有SDS服务器则仅拥有只读访问权。
The primary server has write access to a disk or disk array, while all SDS servers have read-only access.
本例中，我们仅仅使用了一个磁盘，但是如果您打算在每台服务器上安装不止一个磁盘，就要确保每台服务器上的磁盘数目相同。
In this case, we only used one disk, but if you are going to have more than one disk per server, make sure that you have the same amount of disks on each server.
磁盘组件是一个或多个被分配到数据库服务器的磁盘空间单元的集合。
Disk component is a collection of one or more units of disk space assigned to the database server.
而备用服务器直到从主服务器收到消息，得知它磁盘上具有相同的日志，才写入该日志。
The standby system does not write the log until it hears from the primary that that the same log is on disk there.
在创建VIO服务器的过程中，通过为服务器分配存储控制器，就为该服务器分配了磁盘。
In creating the VIO Servers, you assign disks to the server by assigning a storage controller to that server.
如何从无法撤销配置的磁盘恢复服务器，或者取出无法移出这个磁盘的物理分区中的数据？
How could I recover a server from a disk that could not be deconfigured or have the data from a failed physical partition moved off of it?
