DX Object Storage Platform: Advanced Node Configuration

Figure 3: Node Unassigned to a Sub-Cluster

Archive Storage Node Overview

The DX Object Storage Platform allows an administrator to designate a new or empty Storage Node as
an archive Storage Node that remains in idle / low-power state without participating in cluster activity
until its capacity is needed. This enables administrators to have additional capacity available without
paying for the associated power costs of the additional SN.
DX Object Storage automatically load balances across all Storage Nodes in the cluster in order to
maximize capacity and throughput. In adaptive power savings mode, a Storage Node does not go idle
as long as it is servicing incoming application or cluster requests, depriving an administrator of
potential power savings of a Storage Node that is not really needed by the cluster yet. Enabling
archive mode for a new Storage Node will prevent objects from being stored on the SN until the
additional capacity is needed. This is accomplished by raising the bidding on a Storage Node in archive
mode so that it does not win a bid until other nodes become full and the archived Storage Node starts
winning the bidding process and stores new content.
