1.The groups have already collected several petabytes of data (a petabyte can hold roughly 10 trillion copies of this article).
该组织已经收集了数以petabyte（译注：1petabyte=1015）计的数据（一个petabyte可以容纳本文的约10万亿份副本）。
2.As database size grows into terabyte and petabyte, the time and hardware resources required will grow substantially.
当数据库大小增长到GB和PB级时，所需的时间和硬件资源将极大的增长。
3.The new maximum PP size provides an architectural support for 256 petabyte disks.
新的最大PP大小提供了支持256PB个磁盘的体系结构。
4.Its millions of servers process about 1 petabyte of user-generated data every hour.
它数百万台服务器每小时处理用户生成的数据大约就有1拍它（兆兆兆即1015）字节。
5.Some places talk about petabyte datasets in the abstract; we work with them on a regular basis.
一些地方谈论petabyte数据的摘要，我们与他们一道工作定期。
6.But when data sets get to the petabyte scale, the old way simply isn't feasible.
但当数据集达到PB级别的时候，老方法就不那么可行了。
7.reported using Hadoop to sort one petabyte of data in about 16 hours (see Resources to learn more about these benchmarks).
据称雅虎使用Hadoop在16个小时内对1PB（petabyte）数据进行排序（参见参考资料更多地了解这些基准测试）。
8.If you want to scale to the petabyte level, or the billion requests a day, you need to be
如果你想伸展到拍字节（Petabyte，2的50次方，约千万亿）的级别，或者每天数十亿请求，你就需要
9.Easy scalability to multi-petabyte capacity
