hi,i have some doubts ,please have a look as follows: Some days ago, i asked the question that "About MooseFS, If the storage 500T, 3 million files, operating 500G times a day, how much memory the metadata needed? " Your answer is:For 3 million files you need to insert just 4-8GB of RAM into the master server. However,today i see the FAQ about " Does MooseFS have file size limit? Currently MooseFS imposes a maximum file size limit of 2 TiB (2,199,023,255,552 bytes). However we are considering removing this limitation in the near future, at which point the maximum file size will reach the limits of the operating system, which is currently 16EiB (18,446,744,073,709,551,616 bytes). " from the FAQ,such as "Currently MooseFS imposes a maximum file size limit of 2 TiB (2,199,023,255,552 bytes),and so on." i have some doubts,now i want to ask you some questions ,please answer me : problem one: About MooseFS,what size does it support the single file? and what size about the total numbers of file?? problem two: As your answer"For 3 million files you need to insert just 4-8GB of RAM into the master server. ", wether it supports the situation "About MooseFS, if we insert just 4-8GB of RAM into the master server,it'll support the storage 500T, 3 million files, operating 500G times a day"?? That's all ,thanks a lot! Sincerely look forward to your reply! Best regards! Hanyw |
