Microsoft H318Z0CLSK-018X Azure Storage Reserved Capacity

Reserve 10 PB of Azure Storage capacity for the Cool access tier in an Azure Government environment. Microsoft H318Z0CLSK-018X provides a three-year reserved-capacity term for organizations operating large, sustained storage estates where capacity requirements are known in advance. The reservation is aligned to RA-GRS storage, combining geo-redundant replication with read access to the secondary region. The Cool tier fits data that remains online but is accessed less frequently than active-tier content. This configuration combines that access-tier selection with a 10 PB capacity commitment, making it relevant to high-volume retention repositories, archive-adjacent application data, and long-lived datasets that must remain available within the Azure Government cloud. RA-GRS is the defining redundancy selection for this reservation. It differs from capacity reservations tied to other replication options by supporting read access to replicated data in the secondary region. The 10 PB size distinguishes this configuration from smaller capacity tiers, while the three-year term distinguishes it from shorter reservation durations. Select it where the storage account configuration, Cool tier requirement, Azure Government environment, replication mode, and capacity requirement all align.
