STOR2RRD provides storage performance and capacity monitoring for IBM DS8000, IBM Storwize, and IBM SVC. It generates historical, future trends, and nearly "realtime" performance utilization graphs of monitored storages. It graphically presents the IO rate, data throughput, and response times for all Ports, Pools, Ranks, Mdisks, Volumes (LUNs), and drives. It collects complete physical and logical configuration of all storages.
