Data from CNZZ: According to the data from CNZZ, domestic netizens now spend most time on web online games while the fewest on single social network game.

数据来自CNZZ：根据CNZZ的数据来看，国内的网民们在网页网络游戏上花费的时间最多，而在单人社交游戏上花费的时间最少。

We distributed the DASD for the user mail boxes over these mount points.

我们将用于用户邮件箱的DASD分布在这些挂载点上。

After being read in from DASD, the data and index pages go into these slots and remain there until the DB2 buffer manager determines that those slots should be used for some other data.

数据和索引页被从DASD中读出之后，便进入这些插槽，并留在其中，直到DB2缓冲区管理器确定那些插槽要用于其他数据。

This instructs DB2 to pass the index keys to the sort program in memory, rather than having the keys written to and read once again from sort work files on DASD.

这将指示DB2将索引键传递给内存中的排序程序，而不是再次将这些键写到DASD上的排序工作文件中，然后从中读取这些键。

互联网摘选

Years ago in I/ T the cost and space of DASD was a more important consideration.

数年前，在I/T中DASD的成本和空间是更重要的考虑因素。

互联网摘选

A storage group is a set of volumes on a physical storage device, DASD ( direct access storage devices) on the mainframe.

存储组是大型机上物理存储设备DASD（直接访问存储设备）上的一组卷。

互联网摘选

Also, we added four more CPs, increased the memory to26 GB, and added more DASD to support the full user load.

而且，我们又增加了4个CP，将内存增加到26GB，并增加更多DASD，以支持全部用户负载。

互联网摘选

Place the partitions for the table space and indexes on separate DASD volumes and ( if possible) separate control units in order to minimize I/ O contention.

将用于表空间和索引的分区放在单独的DASD卷中，并且，如果可能的话，要隔开控制单元，以减少I/O争用。

互联网摘选

The more often that the data requested by applications is in memory rather than out on DASD, the better overall performance will be.

应用程序所请求的数据出现在内存中（而不是外面的DASD上）的概率越大，总体性能就越好。

互联网摘选

The classical concurrent mode volume groups ( VGs) only supported Serial DASD and SSA disks in conjunction with the32-bit kernel.

经典并发模式卷组（Volumn Group，VG）仅支持串行DASD和SSA磁盘以及32位内核。

互联网摘选

The disadvantage is that the System z I/ O architecture specifies that only one I/ O operation can be active at any time on a specific target device ( UCB or DASD subchannel).

缺点是，System z I/O架构规定，一个特定的目标设备（UCB或DASD子通道）上每次只能有一个活动的I/O操作。

互联网摘选

However, over-allocating free space may result in wasted DASD space, less data transferred per I/ O, less efficient use of buffer pools and more pages to scan.

然而，过多地分配空余空间可能会产生浪费的DASD空间，导致每次I/O只能传输更少的数据，缓冲池的利用效率更低，并且要扫描更多的页。

互联网摘选

This is accomplished by increasing VPSIZE as long as the number of DASD I/ Os keeps decreasing until the cost of paging outweighs the benefit of the reduced I/ O.

为实现这一点，要使DASD I/O的数量持续下降，并不断增加VPSIZE，直到换页的成本超出了通过减少I/O所带来的好处为止。

互联网摘选

Typically, users will store objects into DASD initially.

典型情况下，用户最初会将对象存储在DASD中。

互联网摘选

Such designs not only waste DASD space, but also require higher resource consumption for many DB2 operations.

这种设计不仅浪费DASD空间，而且，对于很多DB2操作，还需要消耗更多的资源。

互联网摘选

In a sense," DASD is cheap," and bandwidth is also getting cheaper(" DASD "is an old IBM way of saying" hard disks"; and the phrase is a design cliche).

在某种意义上，“DASD很廉价”，带宽也变得越来越廉价（“DASD”是IBM对“硬盘”的旧称；这个措词在设计上很陈腐）。

互联网摘选

Let's simulate this scenario, assuming that objects stay six months in DASD, three years in external storage, and seven years in tapes.

让我们来模拟一下这个场景，假设对象在DASD中存储6个月，在外部存储中存储3年，在磁带中存储7年。
