Microsoft DZH318Z0CLSK-013Q Azure Storage 10 PB GZRS Reservation

Reserve 10 PB of Microsoft Azure Storage capacity for the Cool access tier in the US Central region. The reservation applies a 3-year committed term to geo-zone-redundant storage (GZRS), combining zonal resilience in the primary region with replication to a paired secondary region. It is suited to organizations retaining large volumes of infrequently accessed data while maintaining a defined storage redundancy configuration. Microsoft DZH318Z0CLSK-013Q represents the 10 PB capacity level rather than a physical appliance or separately deployed storage platform. It is a cloud capacity commitment for Azure Storage consumption. The Cool tier is intended for data kept online but accessed less frequently than hot operational data, making it appropriate for retained application content, historical files, media repositories, backup data, and long-lived analytics source data where access remains necessary. Within Azure Storage reserved-capacity options, this selection is distinguished by four fixed characteristics: 10 PB of reserved capacity, the Cool tier, GZRS redundancy, and US Central regional scope. The 3-year term is the longer commitment period for capacity planning where the storage footprint and redundancy requirement are expected to remain stable. Select this reservation when the intended Azure Storage usage requires Cool-tier GZRS capacity in US Central at the 10 PB level.
