what you think about adding ceph crush support? about vasto HOT 3 OPEN

For CRUSH, the configuration is just super complicated to just add a node.

Currently the design is using Jumping Consistent Hash. I compiled a few slides here:

Why using crush if super compilcated to add a node?
ceph already not need to modify crush map by hand. When node stars it run script that add node and it disks via well known rules.
For example when run binary you can automatic add node to crushmap and all it "disks".

the complicated part is not just what scripts to run, but what state/rule needs to keep consistent when a node goes up/down, or when transitioning to a different cluster size.

The rules are much more complicated than a hash algorithm with 2 input numbers.
