Suppose I have a filer (760) with about 50 million files -- between 1k and 500M. What would be the optimum directory structure to keep them all? So far I have the following:

/vol/vol1/data/Z/XX/XXXX/<full_usr_name>/files

where XX and XXXX are the first 2 and first 4 characters of <full_usr_name> and Z is a hash spliting the <full_usr_name> between 2 filers -- yes, we have a rather large system ;)

This seems to be working fairly well, but I am wondering if there isn't a better way of doing it.

Does anyone knows how Netcaches keep their URLs in memory? Could you use that methode for the above?

Any ideas?
