It produces a snapshot of the current working set (the pages actually in main memory at a given point in time).
主存中的每个位置都使用连续的数字地址编号，内存位置就使用这个地址来引用。
Every location in main memory is numbered with a sequential numeric address by which the memory location is referred.
除此之外，最大的问题是，主存储上重复数据所占的比例要比备份数据要低得多。
Beyond that, the big problem is that primary storage has a much lower percentage of duplicate data than backup data.
在主存储库与节点存储库间执行配置同步，以将已更新的应用程序部署到该节点。
Performs configuration synchronization between the master repository and the node repository, thus bringing the updated application down to the node.
当要在缓存中存储的数据量超过应用程序服务器系统的主存时，您就可以使用此功能。
You can use it when the amount of data to be stored in the cache exceeds the main memory of the application server systems.
但请记住它们指向在应用程序主存储内的内存(有效地址)，而非到SPE的本地存储。
However, remember that they point to memory in the main storage of the application (an effective address), not to the SPE's local store.
由于允许对频繁使用的数据进行快速存取，软件运行要比从主存储器中存取数据快得多。
By allowing fast access to frequently used data, software can run much faster than if it had accessed the data from the main memory.
由于数据在整个集群中进行复制，集群中的每个服务器都有足够的主存来存储整个上下文数据。
Because data is replicated across the cluster, each server in the cluster has enough main memory to store the entire context data.
重复数据删除在备份市场已经非常流行，但是因为某些因素其在主存储上的价值一直被质疑。
Deduplication has been very popular in the backup market, but its value in primary storage is questionable for several reasons.
在这种技术中，一个主存储控制器为相同或不同厂商提供的其他存储控制器提供虚拟化服务。
In this technique, a primary storage controller provides the virtualization services for other storage controllers of same or different vendors.
如果TLB没有命中，那么就需要访问存储在主存中的页表，而这样做需要消耗相当多的处理器周期。
A TLB miss requires accessing a page table that is stored in the main memory, which consumes considerably more processor cycles.
SPE在本地存储中的地址称为本地存储地址(LSA)，而在主存内的地址称为有效地址(ea)。
Addresses within an SPE's local store are called local store addresses (LSAs), while addresses within the main memory are called effective addresses (EAs).
此系统的一个主要优点是，在使用备份系统时，对部署管理器的主存储库所做的任何更改都会被提交。
One major advantage of this system is that any changes made to the deployment manager's master repository while using the backup system are committed.
在WebSphere主存储库中进行了应用程序更新（由部署管理器控制）后，将会调用此命令。
This command is expected to be invoked after the application is updated in the WebSphere master repository, which is controlled by the deployment manager.
对于DB2，系统主存的最大消耗者是它的缓冲池，这个缓冲池基本上是一个单独的、较大的共享内存区域。
For DB2, the largest consumer of system main memory is its buffer pool, which is basically a single, large Shared memory region.
当主存储配置与节点同步后，应用程序配置将复制到节点级别的存储库中，并提取到应用程序安装目的地中。
When the master repository configuration is synchronized with a node, the application configuration is replicated in the node level repository and extracted in the application install destination.
回过来参看图1，部署管理器的主存储库存储着所有版本6标准的配置文件，还设计成能够适应版本5的配置信息。
Referring back to Figure 1, the deployment manager master repository stores all configuration files at the V6 level, but is designed to also accommodate V5 configuration information.
但是当将相同的代码移植到一台主存地址从0x8000000开始的68030机器上时，这些代码就会死掉。
But the same code died horribly when someone introduced a 68030 machine with main memory starting at 0x8000000.
您可以将变量的这些“线程局部”副本看作是与缓存类似，在每次线程需要访问变量的值时帮助它避免检查主存储器。
You could consider these "thread-local" copies of variables to be similar to a cache, helping the thread avoid checking main memory each time it needs to access the variable's value.
此外，中间件还可以对这些缓存进行管理，从而减少主存的压力，并能在处理器之间复制这些信息，以改善工作负载管理。
In addition, the middleware can manage these caches to reduce pressure on main memory and copy them between processors to improve workload management.
