This opens up the prospect of configuring VGs with a relatively small number of disks and fine-grained storage allocation options through a large number of PPs, which are small in size.
这使得我们能够通过较大数量的 PP，以较少数量的磁盘和细粒度的存储分配选项来配置 VG，其中这些 PP 的容量很小。
The terms loose coupling (a small amount of fragility) and tight coupling (a large amount of fragility) are often mistakenly used as synonyms for coarse-grained and fine-grained components.
术语松散耦合（脆弱性较小）和紧密耦合（脆弱性较大）经常被人当作粗粒度组件和细粒度组件的同义词误用。
As such, they're tuned for a relatively small number of cores (two to eight) running coarser grained, possibly blocking transactional tasks that have few inter-task dependencies.
它们是为相对少数的核心(2到8个)而调优的，这些核心运行粗粒度的、可能会阻止具有较少任务相关性的事务型任务。
