FlashSystem 5100 2078-UHB

The IBM 2078 Model UHB is the FlashSystem 5100 hardware component to be utilized in the Storage Utility Offering space. It is physically and functionally identical to the V5100 model 4H4 with the exception of target configurations and variable capacity billing. The variable capacity billing uses IBM Spectrum Control Storage Insights to monitor the system usage, allowing allocated storage usage above a base subscription rate to be billed per TB, per month. Allocated storage is identified as storage that is allocated to a specific host (and unusable to other hosts), whether data is written or not. For thin-provisioning, the data that is actually written is considered used. For thick provisioning, total allocated volume space is considered used
