The XtremIO Cluster Layer

This layer monitors the level of I/O activity of each cluster and space usage of each SSD in a cluster of the EMC XtremIO. In addition, this layer helps administrator to keep a check on the I/O processing capability of the cluster based on the data block size so that lag in read/write operations can be detected and precautionary measures can be initiated before any serious damage occurs.
