Abstract:
A storage node administration device enables setting a logical capacity of a storage region based on an I/O performance value of a storage node. In a distributed data storage system, the storage node administration device includes a setting unit setting at least one reference node from a plurality of storage nodes having different I/O performances, dividing a storage region of the storage nodes other than the reference node into a first storage region and a second storage region, referring to the I/O performance and the logical capacity of the reference node, and setting the logical capacity of each region to match the I/O performance of the storage nodes other than the reference node; a determination unit determining system configuration information which reflects a configuration change of the distributed data storage system; and a transmission unit transmitting the system configuration information to the storage nodes having different I/O performances.
