异构机器调度　是啥，AddBlock时考虑机器的不同性能？

对，磁盘大小、读写性能不一样

"读写文件优先选择Client本地副本"　是说根据client与cs之间的距离吗？（比如IP）

对，现在发现即使在万兆网卡环境下，bfs也能把网卡占满
如果能让一个副本放在本地，能降低网卡1/3的负担

那这个副本什么时候删呢

bluebore commented Jan 4, 2016

这个只是普通的3副本之一，不需要额外删除
AddBlock选chunkserver的时候，优先选择和Client的ip一样的cs
SDK读的时候，也优先选择和自己IP一样的cs去读

client那台机器上有cs的概率会很大？

几乎100%
bfs的目标是管理数据中心中所有的磁盘，所以每台机器上都会有cs
