To use HTI, HDP, and the other VSP G200, G400, G600 storage system software applications, you must acquire licenses with Hitachi Data Systems (see Dynamic Provisioning.)Thin Image pairs
An HTI pair consists of a P-VOL, one or more S-VOLs, and one or more pool-VOLs. An S-VOL is only necessary if you want to create an HTI pair with an S-VOL specified. Otherwise, an HTI pair consists of a P-VOL and one or more pool-VOLs.
The P-VOL is an individual logical data volume, or logical device (LDEV). The S-VOL is a V-VOL. LDEVs include V-VOLs of provisioning type HDP. Only a V-VOL created for HTI can be specified as an S-VOL. P-VOL differential data is stored as snapshot data in pool-VOLs (LDEVs).
To use HTI, HDP, and the other VSP G200, G400, G600 storage system software applications, you must acquire licenses with Hitachi Data Systems (see Dynamic Provisioning.)
