Subject: An Evaluation of Object Name Hashing

Hi,
I wrote a Master's Thesis about Ceph and cold storage last year. One of
the things I looked at was modifications to object placement.
Among others, what would happen to balance (e.g objects / OSD) when
all objects of a file end up on the same OSD. I also ran tests with a
different hash algorithm (Linux dcache).
I wrote an article on my website with the analysis, changes to the
source and how I ran the tests:
