Microsoft H318Z0CLSK-018R Azure Storage 10 PB Cool GRS Reservation

Reserve 10 PB of Azure Storage capacity for a three-year term in the Azure Government cloud environment. Microsoft H318Z0CLSK-018R corresponds to Cool-tier storage with geo-redundant storage (GRS), aligning the reservation with an Azure Storage configuration that maintains replicated data in a paired geographic region. The Cool access tier addresses storage retained for less frequent access than actively used data while remaining online in Azure Storage. GRS adds geographic replication beyond locally redundant copies, supporting storage architectures that require a secondary-region data replica. The reservation applies to storage capacity rather than physical equipment, making it relevant to cloud-hosted data estates with sustained capacity consumption. This specific reservation combines three attributes that must match the intended Azure service use: 10 PB capacity, the Cool storage tier, and GRS redundancy in Azure Government. Its three-year duration distinguishes it from shorter commitment options, while the Azure Government designation separates it from reservations intended for commercial Azure environments. Validate the storage tier, redundancy selection, cloud environment, and required capacity before assigning the reservation to an Azure subscription.
