Object data is managed through the active ILM policy and its ILM rules. Through ILM rules, object data is protected from loss through replicated and erasure coded copies.
Object metadata is managed by the DDS service.
More information
Content protection: replication
Following ingest, if an ILM rule’s Content Placement instructions are configured to make replicated copies of object data, copies are made and stored to disk through the LDR services of Storage Nodes that make up the configured storage pool.
Content protection: erasure coding
Following ingest, if an ILM rule includes instructions to make erasure coded copies of object data, the applicable erasure coding scheme breaks object data into data and parity fragments and distributes these fragments across the configured storage pool's Storage Nodes.
