The idea is related to Hitachi Device Manager ETL for TrueSight Capacity Optimization.
At the moment it supports only SMI-S connection to Hitachi Disk Array VSP G Series (VSP G200, G400, G600, G800 and G1000). Connection to Hitachi Device Manager (HDM) is not provided. See BMC Docs for details - https://docs.bmc.com/docs/TSCapacity/110/deploying-and-configuring-hitachi-device-manager-etl-for-truesight-capacity-optimization-674154476.html
Following few customer requests we are asking to add HDM connectivity for VSP G Series.
- it is more secure;
- less overhead, as all storage data are collected from one centralized location;
- most of other Hitachi storage systems support HDM.
