Selection strategy on clustered node and client selection mode outside server cluster node.Implementation is as follows:
Assume that server cluster has n frame, each frame to have TR platform service node, if number of copies is that r client is at clothes
On business device group service node, then
A) client sends write data requests to management node；
B) management node is according to file content and system configuration scenarios, calculates all service nodes of client place frame
Stored ratio, process is as follows
If client is i-th frame, initialize selected node set SDN for sky；
The residual capacity of this frame jth node is CLij, the block number of storage is BLij, the storage preferred proportion RS of nodeij
=CLij/BLij, storage is preferably put into selected node set than two the highest nodes, i.e. SDN={DNia、DNib}；Wherein
DNia、DNibRepresent a and the b service node in i-th frame,
C) from remaining the node calculating r-2 storage each frame than maximum, r-2 node of maximum after sequence, is selected
Put into selected node set SDN, altogether r node, be used for depositing data block and copy thereof；
D) the node distribution service node during SDN is gathered by management node, to client, is write by client.
When client is not on service node, then the stored ratio of all nodes, choosing in direct calculation server cluster
Select front r maximum node, be data memory node.FromIn individual node, according to RSij=CLij/BLijSelect storage
R the node that ratio is the highest, puts in SDN list, is the optimum node chosen.
