使用存储策略筛选器表达式。
之前文档版本的存储策略。
为文档类型设置的存储策略
为文档设置的存储策略。
相反，最好只对文档类型设置存储策略属性。
Instead, it is best to only set the storage policy property on a document class.
然后将该存储策略指定给基本 P8 文档类型。
This storage policy is then assigned to the base P8 document class.
但是首先需要看看如何在P 8中创建存储策略。
But first, it is a good idea to go over how you create storage policies in P8.
也可以将一个存储区域与多个存储策略关联。
You can associate storage areas with more than one storage policy.
可支持创建定制存储策略的简单基础构架。
接下来将更详细地描述存储区域和存储策略。
Storage areas and storage policies are described in more detail in the next sections.
也可以在创建新存储区域时创建新存储策略。
You can also create a new storage policy when you create a new storage area.
这个特性仅在复制节点和在随需存储策略的复制中支持。
This feature is needed only for replicated nodes and replication on demand storage strategies.
此外，存储策略是并行性和多租户的一个重要组成部分。
In addition, the storage strategy forms an important component for parallelism and multi-tenancy.
一个存储策略有一个或多个存储区域与之关联。
A storage policy has one or more storage areas associated with it.
满足表达式的存储区域被关联到这个存储策略。
Storage areas that satisfy the expression are associated to this storage policy.
BigMemory在内存存储策略上有别于传统的缓存解决方案。
BigMemory differs from traditional caching solutions in its memory storage strategy.
本节描述如何使用存储策略筛选器表达式更具体地选择存储区域。
This section describes how to use a storage policy filter expression to perform specialized selection of a storage area.
有2种主要方法可通过存储策略充分利用P8环境中的存储资源。
There are two primary techniques for using storage policies to best utilize your storage resources in a P8 environment.
在上一节中，您显式地指定了将哪些存储区域用于特定的存储策略。
In the previous section you explicitly specified which storage areas to use for a particular storage policy.
例如，可以将用于媒体文件的文档类型的存储策略指定给具有大容量的磁盘。
For example, you might assign a document class's storage policy used for media files to disks with very large capacity.
存储策略是一种选择机制，用于确定最终存储文档内容的存储区域。
A storage policy is used as a selection mechanism to determine the storage area in which a document's content is ultimately stored.
使用CreateaStoragePolicy向导创建存储策略。
Using the create a storage policy wizard to create a storage policy.
该过程使用FEM创建一个存储策略，并为之指定一个存储区域列表。
The procedure USES FEM to create a storage policy with an explicit list of storage areas that are assigned to it.
如前所述，有两种方法可通过存储策略充分利用P8环境中的存储资源。
As described earlier, there are two techniques for using storage policies to best utilize your storage resources in a P8 environment.
例如，可以使用存储策略筛选器根据存储区域的最大大小来选择存储区域。
For example, you could use a storage policy filter to select a storage area based on the maximum size of the storage area.
然后，创建一个存储策略，该存储策略均匀地将文档分布在这些存储区域上。
Then create a storage policy that evenly distributes documents across these multiple storage areas.
虽然也可以不将新存储区域与新的或已有的存储策略相关联，但不建议这样做。
Although, you have the option of not associating the new storage area with either a new or existing storage policy, this is not recommended.
在为给定存储策略指定存储区域时，筛选器表达式提供了一种更加灵活的机制。
Filter expressions provide a more flexible mechanism for specifying which storage areas to select for a given storage policy.
可以使用存储策略建立一个存储区域场，通过分布I/O负载提高吞吐量。
You can use a storage policy to set up a storage area farm to increase throughput by distributing the I/O load.
本文后面的使用存储策略筛选器表达式一节将更详细地讨论存储策略筛选器表达式。
The Using storage policy filter expressions section later in this article discusses storage policy filter expressions in greater detail.
