Subject Cache Write Algorithm
Date Wed, 13 Apr 2016 12:41:45 GMT
Hello, 


Two questions on ATS cache write logic

1) How does ATS balance write load across different storage devices? (Round-robin, least I/O
load, etc??)


2) How does ATS handle caching large files near the end of cache spans? For example, I want
to cache a 200MB object but my write pointer is only 50MB from the end of the cyclone buffer?
I know ATS will not split files across cache spans, so will it skip the last 50MB and wrap
back to the beginning of the buffer?


Thanks,
Eric
