In this paper, the authors are focused to the real implementation of the data cluster based on the technology. The first part is focused to the solution with geographically separated nodes placed on the shared network infrastructure. Each node; store point is in different physical location and on different subnets. The second part of this paper shows the comparison of the separated node and no separated nodes. The non-separated solution is located in one room with one isolated network infrastructure. Realized test show the dependency of number of concurrent clients connected to the cluster and cluster read/write bandwidth. These tests show the potential limits of the developed solution. The test compares the effect of shared infrastructure and geographical separation of data-cluster nodes.
