Microsoft DZH318Z0CLSK-017L Azure Storage Reserved Capacity

Reserve 10 PB of Azure Storage capacity for the Cool access tier in US East under a three-year commitment. Microsoft DZH318Z0CLSK-017L is an Azure Storage Reserved Capacity offer for environments that maintain very large volumes of data that do not require the access profile of the Hot tier. It applies a defined reserved-capacity term to storage consumption rather than supplying physical storage hardware. The offer specifies Geo-Zone-Redundant Storage (GZRS). GZRS combines storage replication across availability zones in the primary Azure region with geographic replication, making it relevant where retained data requires both regional resilience and a geographically separated copy. The US East designation matters: reserved capacity is tied to the named Azure region and storage redundancy option. This configuration is distinguished by four fixed selections: 10 PB of capacity, the Cool storage tier, GZRS redundancy, and a three-year term. Those choices suit long-lived backup repositories, retained application data, analytics data lakes, and large archival datasets where storage scale and redundancy requirements have already been established. Select it when the intended Azure Storage workload uses Cool-tier capacity in US East and requires the GZRS replication class for the full reservation period.
