从Nutanix的圣经中：“当策展人进行全扫描运行时，它将找到可以编码的合格范围组。符合条件的范围必须“写下”，这意味着他们已经有一段时间没有写了。
我有2个问题：
如果我只写了一些数据，那么假设没有任何阅读，则在范围存储中复制这些数据需要多长时间？
一旦数据在范围内存储，将擦除编码应用于数据之前需要多长时间？

As you can imagine, there is no set timeframe to write data between the two locations in the storage layer. Per-vDisk OpLog limit is 6GB. We can simplify it terribly and say, we are draining all 6GB (not realistic) for all vDisks at the same time (even less realistic), how long will it take?<\/p>
In real life, it would be chunks of data written to the extent store from the OpLog if the vDisk is idle for some time or when the OpLog is at 85% capacity. Regular curator scans identify chunks that are old enough to be moved to the cold tier and to be processed for EC if it is enabled.<\/p>
Cold data constitutes no write within the past 7 days. That is calculated from the moment the data arrives at the extent store.<\/p>
Let me know if that helped or if you have more questions.<\/p>","className":"post__content__best_answer"}">
