Supporting Heterogeneous Pools in a Single Ceph Storage Cluster
Stefan Meyer, John P. Morrison · 2015
In a general purpose cloud system efficiencies are yet to be had from supporting diverse application requirements within a heterogeneous storage system. Such a system poses significant technical challenges since storage systems are traditionally homogeneous. This paper uses the Ceph distributed file system, and in particular its concept of storage pools, to show how a storage solution can be partitioned to provide the heterogeneity needed to support the required application requirements.
