what mean :
Performance was slow when Sheepdog used the server as the node for its
consistent hashing algorithm, according to Dong. If one disk failed,
the server fetched the data from other servers and calculated the
result of the erasure code to recover the lost data, he said.
To remove the bottleneck, the team used the hard disk instead of the
server as the node for the consistent hashing algorithm, enabling all
the servers in the sub-cluster to participate in the recovery work if
a hard disk failed.
